Abstract: A filter system for achieving continuous filtering by the provision of three filter chambers disposed about a common vertical axis, each containing a filter bed comprised of buoyant particles through which the fluid to be filtered is passed in an upward direction and wherein provision is made for rehabbing the beds of particulate material as they become filled with solids, preferably in succession to enable continuous operation.

Abstract: A fitting for connecting a drum containing a fluid product to a pipeline leading to a place of use without introducing contaminant.

Abstract: As herein illustrated, the device comprises a central, elongate, hollow core embodying oppositely-diverging, truncated cones integrally-connected at their smaller ends to each other, an annular gripping portion disposed about the core intermediate the opposite ends defining with the core an annular chamber about the core and a plurality of radial fins disposed in the chamber about the core connected at their opposite ends to the core and the annular gripping portion. The annular gripping portion is of generally spherical configuration and is connected at its opposite ends to the core by annular flanges. Desirably, the annular gripping portion is in the neutral area of the aero slip stream created by the ends of the leading and trailing cone ends.

Abstract: A device for automatically opening and closing a door by turning the door through an angle of 90.degree. from an open to a closed position and vice versa.

Abstract: A golf club provided with a head formed of a translucent plastic within which is disposed, preferably adjacent to the striking face, a chemiluminescent light stick.

Abstract: This invention relates to shoesoles for the bottom of golf shoes and especially to shoesoles provided with, in addition to conventional spikes at the forepart and heel, ground-engaging protrusions distribution along the inner and outer marginal edges of the soles to enhance the stance of the golfer.

Abstract: An intraruminal device has hinged wings (6) which lie along the body of the device during administration to the animal but which are urged outwardly by a spring (14) acting on a piston (12) shortly thereafter. The wings (6) are locked in the extended position: the piston (12) prevents them returning to the starting position, and T-bars (10) prevent them continuing to an "arms-over-head" position.The locking means may comprise a latch. The spring (14) may be replaced by a water-swellable polymer which expands on contact with rumen fluids.The device is used to administer drugs or minerals to the rumen of a ruminant over a prolonged period.

Abstract: Contact lens (1) comprising a rear contact surface (2) presenting a spherical region described by an arc of a circle passing by the vertex (S). In order to improve the optical properties while improving the adaptability and compatibility, the contact lens (1) presents an aspherical region adjacent to the spherical region; the curve representing the aspherical region and the arc of a circle representing the spherical region have in the transition a substantially equal curvature radius (R.sub.o) and a substantially equal slope.

Abstract: An elongate handle for attachment to the stem of a valve provided with a clamp for receiving the stem and a bolt and nut for drawing the clamp into clamping engagement with the stem.

Abstract: A trench box wherein there are spaced, parallel side wall panels between which there are spacer panels and wherein the upper longitudinal edges of the side wall panels and spacer panels are transversely inclined.

Abstract: A bent wire spring module embodying a clamp element at the upper end interengageable with the cross wire of a grid frame without requiring the formation of deviations in the cross wire to which it is attached.

Abstract: Apparatus and method for packaging particulate product in bags for deposit into cartons of predetermined cross section and height. Sheet material is formed about a filling tube. The sheet material is sealed and severed beneath the filling tube creating the top of one bag and the bottom of the next. Product is dropped through the filling tube into the formed sheet material which is vibrated. A sensor may be used to determine if product exceeds a predetermined height. After a predetermined amount of product has been dropped into the sheet material, the material is lowered, sealed and severd to form a filled bag.

Abstract: Apparatus for forming bags of predetermined length with a predetermined weight of product, the apparatus being provided with a vibrator for effecting vibration of a bag shaper and a sensor adjacent the bag shaper for determining when the product has subsided to a level less than the height of the bag so that jaws may be engaged to seal the top of the bag without being jammed by product.

Abstract: A feeding means for feeding a material web in a packaging machine comprises feeding chains, sprocket wheels and an engagement element for feeding the feeding chains. In order to facilitate the insertion and clamping of the material web the engagement member is designed such that in a first portion of the travelling section the movable clamping member is lifted from the fixed clamping member in a substantially vertical direction and in a second portion of the travelling section following the first portion the movable clamping member is additionally moved laterally away from the edge of the material web to be gripped.

Abstract: An electrolytic cell of a liquid disinfection device has a housing with an inlet and outlet, and electrodes arranged in transverse planes and surrounding a central supporting element through which electrical leads can be provided. The electrodes can be concentric annular electrodes supported on radial supports, or can be unitary, being punched from sheets with gaps and webs between them.

Abstract: A bedspread with a panel attached to one end thereof to overlay pillows at the head of the bed, wherein the bedspread and the panel are provided with aligning tabs at the head end spaced apart a distance corresponding to the width of the mattress to thus enable centering the bedspread and the panel with respect to the mattress and pillows so that equal lengths thereof hang down at opposite sides.

Abstract: A grid frame for a spring assembly comprising a border wire transversely and longitudinally-crossing line wires, and spring wires disposed between adjacent line wires either transversely of the frame or longitudinally thereof.

Abstract: A hanger for a flexible wall covering in the form of an elongate flexible strip adapted to be attached to a wall adjacent the ceiling, provided with elastically interengageable jaws normally standing apart to admit an edge of the wall covering and thereafter interengageable to anchor the wall covering suspended therefrom in contact with the wall.

Abstract: A device for removing putty from a window frame in the form of an L-shaped blade and a support to which the blade is adjustably attached, the support being provided with a handle and guide by means of which the blade can be moved along the window frame adjacent the groove within which the putty is located to remove the putty from the groove.
