Abstract: Frozen compositions of lactic acid producing bacteria which incorporate an alkali metal salt of glycerophosphoric acid are described. These salts reduce damage to the bacteria upon freezing and storage which with certain bacteria is evidenced by enhanced lactic acid forming activity upon thawing and use of the compositions as fermented dairy product starter cultures.

Abstract: A control for brakes in trailer vehicles comprising a circuit providing pulsed signals to the brakes. It is preferred that the time or width of each pulse is equal but the frequency of brake pulsing is increased in accord with inertially sensed stress. The frequency of signal is directly related to the movement of a dampened cantilever beam which normally blocks the passage of light to a light sensitive target or monitor but wherein the passage of light increases and is attenuated by the beam as the beam moves, under inertial imbalance, to permit added light to be sensed. In addition, the control circuit, vulnerable to short circuits in the vehicle circuit from control element to brakes, is continuously monitored by a disconnect element which senses the existence of the short circuit and accomplishes a disabling of current through the control circuit at a threshold to avoid injury to the control circuit.

Abstract: An improved compression pivot and support combination as for remote control rearview mirrors and the like, having an arcuate lobe integrally depending from a bar and the bar including integral spherical extensions at the ends thereof and wherein the connecting bar has a triangular cross section configuration intersecting the spherical profiles of the spherical extensions. The support sockets or dimples into which the spherical extensions are inserted are spaced apart in the support face and one of such dimples is elongate.

Abstract: Colorimetric indicator compositions and their method of manufacture. A first reagent composition is included in the indicator compositions so that when a second reagent composition is applied to an exposed surface of the indicator compositions a reaction occurs to produce a color change. The indicator compositions include as one component a thermoplastic resin which is soluble in a liquid carrier for the second reagent composition at ambient temperatures. Particularly preferred indicator compositions incorporate a particulate coloring or contrast agent in the resin which, when the liquid carrier containing the second reagent composition is applied on an exposed surface of the indicator compositions containing the first reagent composition, dissolves the resin at the surface to provide a contrasting color background of dispersed particles in the liquid carrier.

Abstract: A method for testing milk to determine its ability to be fermented by bacteria in order to produce cheese, cottage cheese and the like is described. The method utilizes a colorimetric oxidation-reduction dye which rapidly changes color when the milk is readily fermentable.

Abstract: A vehicle sensitive inertial retractor for safety belting and the like which includes a frame or base supporting a webbing receptacle in the form of a spring motor loaded reel or drum and biased to rewind. The frame also supports a saddle and the saddle provides a fulcrum seat for an inertially displaceable pendulum mass. A lever, pivotal in the frame is positioned to engage the pendulum in a following relation and a finger portion of the lever holds a face clutch plate against movement corresponding to the outgoing of the adjacent drum or reel which accompanies withdrawal of webbing. The clutch plate includes a cam portion which normally blocks a spring biased pawl bar from lock engagement with ratchet wheels on the reel or drum. Clutch rotation limiting means are also provided in the frame of the retractor restricting the extremes of rotation of the clutch plate in the manner of a stop.

Abstract: A method is described for making fermented or "sour" flour having distinctive flavor and acidic properties when incorporated into baked products. Flour and substantial amounts of water are mixed together and fermented with a non-toxic Lactobacillus bacterium and then dried to less than about fourteen (14%) percent by weight water so as to provide a finely divided flour. The use of Lactobacillus plantarum is particularly disclosed.

Abstract: A pole shaft is provided with continuous loop drive chain means to raise and lower a luminaire ring assembly mounted thereon. A detachable fixed head assembly is provided at the top of the pole shaft and has locating and locking means for fixedly retaining the luminaire ring in its fully raised position. The detachable fixed head assembly is provided with radially extending support arms having sheaves which support lifting and lowering suspension cables that engage the luminaire ring. The suspension cables extend inside the pole shaft and operatively engage a transition plate provided in association with the continuous loop drive chain means. A motor drive assembly is provided in the base of the pole shaft which operates the continuous loop drive chain means and associated limit switch positioning means which control the amount of travel of the continuous loop drive chain.

Abstract: The method of orally feeding animals including humans Lactobacillus lactis NRRL B-5628 to restrict the growth of other digestive system (such as mouth, crop and/or stomach) bacteria is described. NRRL B-5628 is particularly useful in the treatment of scouring, diarrhea or colibacillosis in baby pigs and other newborn animals by reducing the intestinal population of E. coli as the native coliform bacterium. The oral feeding of NRRL B-5628 is also used in farrowing sows to reduce intestinal bacteria and in turn to reduce such bacterial populations in the newborn pigs. Mastitis-metrites syndrome in gilts, sows and cows is reduced by such oral feeding.

Abstract: A method for forming integral internal channels defined by a wall with an annular cross-section inside high softening temperature glass tubing is described. In particular, a reduced pressure is provided inside a rotating tube with heating outside which softens the glass for deformation by the reduced pressure while a smaller tube is maintained in position in contact with the inside walls of the larger tube. The pressure in the smaller tube is usually the same as that in the larger tube and is such that it can collapse at the point of contact to form at least one fusion band along the inside wall of the larger tube. The position of the smaller tube is maintained such that the larger tube has concave depressions between the fusion bands. Usually the heating is accomplished by a gas flame ring burner positioned under the larger tube and moved progressively along the larger tube until the desired fusion of the tubes is completed.

Abstract: A piston ring tension gage consisting of a ring compression test fixture provided with a digital strain readout indicating for automatically determining the pressure exerted by a piston ring assembly in a simulated operative use position. The ring compression test fixture comprises a fixed semi-circular plate which coacts with a pivotally mounted movable semi-circular plate to retain a piston ring assembly therebetween. A pneumatic cylinder and piston rod provided with a strain load sensing means acts directly against the movable plate so as to determine the pressure exerted by the piston ring being tested. Vibratory means are provided in association with the ring compression test fixture so as to obtain friction free test reading. The tension measuring, vibration and tension reading steps are automatically sequenced at a controlled rate to provide repetitive accuracy in the testing.

Abstract: A locker retractor for seat belt harness and the like which includes an interposer element articulated by movement of the drum or reel to selectively block or release a spring biased pawl bar and holding the pawl bar away from locking a ratchet on one or both of the reel flanges or selectively freeing the pawl bar so that it may lock the ratchet in prevention of further drum rotation in the withdrawal direction. The shift from blocking to non-blocking position is achieved by a slight retraction of the webbing after initial free withdrawal, whereupon the interposer element falls free of its blocking relation. The interposer is a latch-like element pivotally and slidably connected to the frame and oriented and frictionally directed by a ring element turned by the moving of the drum. The interposer described is also useful in providing quiet free-pull and retraction in inertial retractors as described in copending application Ser. No. 258,576 filed on June 1, 1972 now U.S. Pat. No. 3,865,320.

Abstract: A saddle pawl and pendulum support for vehicle sensitive inertial retractors having a saddle element which pivotally supports a pawl and which also supports, in spaced-apart relation, a pendulum operable on an omnidirectional seat. The pendulum includes a head element detachable from the pendulum mass and the head element rests on the circular knife edge of the seat and registers beneath a tab extension of the pawl so that upon the tilting of the pendulum in respect to the vertical axis through the seat, the head tilts and engages the tab and tilts the pawl into locking engagement with rotary ratchet teeth provided on a retractor drum or spool. The mass of the pendulum depends beneath the seat and is secured to the head by means of a rod which extends axially through the circular knife edge seat.
