An iron joint is mounted to the aperture of the casing and is formed with an electrically conductive metal coating having a corrosion resistance greater than that of iron on the surface thereof. The iron joint is comprised of a cylindrical portion and a conical outer surface portion welded to the edge of the aperture by resistance welding. A pipe for sucking or discharging gas to or from the casing is brazed into the cylindrical portion of the iron joint with a copper brazing material.

Abstract: A peristaltic pump for pumping fluids through a flexible tube is described which has a quick release and engagement mechanism that permits easy and rapid removal or insertion of the flexible tube into the device. The quick release and engagement mechanism of the invention consists of a shoe mounted for vertical displacement on the body of the pump. Upward movement of the shoe engages the flexible tube holding the fluid to be pumped and locks the tube against the roller assembly containing an eccentrically mounted roller which intermittently engages the tube and forces fluid out of it. To disengage the flexible tube from the pump, the shoe is moved downward out of contact with the flexible tube.

The housing closely follows the contours of the motor and the pump block and is provided with external projections for accommodating accessories for use with the pump unit. A handle is integrally formed at an upward projection of the housing, the upward projection serving as an enclosure for a capacitor connected to the motor.

Abstract: A pneumatic drive circuit for a pneumatically-driven artificial ventricle having a gas chamber and a blood chamber separated by a flexible diaphragm. The drive circuit comprises a source of pressurized gas at a preselected pressure. Valves operatively associated with the gas chamber of the ventricle admit gas to the gas chamber during systole and exhaust gas from the gas chamber during diastole. The drive circuit includes pneumatic logic circuitry for actuating the valves. The logic circuitry includes circuitry for causing the valves to admit gas to the gas chamber during systole at a pressure which increases gradually from zero pressure to a pressure less than the preselected pressure, and then increases rapidly to the preselected pressure.

Abstract: A fan cover for a bypass vacuum motor unit is produced by forming outlet apertures in an intermediate flat blank and thereafter deforming the blank into a pan-shaped structure with the outlet apertures disposed on its cylindrical sidewall. The fan cover affords economies in tooling for its manufacture, uniformity in performance, and reduced noise in operation.

Abstract: An apparatus for transferring a small amount of fluid has at least three vibration pump units which are connected in series. Each vibration pump unit has a fluid transfer pipe, a vibrator mounted on the outer peripheral surface of the fluid transfer pipe and adapted to cause the transfer pipe to vibrate in a respiring manner, an inner peripheral electrode on the inner peripheral surface of the vibrator, an outer peripheral electrode on the outer peripheral surface of the vibrator, a high-frequency voltage applying device for applying a high-frequency voltage between the inner peripheral electrode and the outer peripheral electrode thereby causing the vibrator to vibrate in respiring manner, and a fluid diode exhibiting resistance to reversing of the fluid and connected to the fluid outlet of the fluid transfer pipe in such a manner as to permit the fluid to be discharged from the fluid pipe. The adjacent vibration pumps operate with a predetermined phase difference therebetween.

Abstract: A golf training device in which there is a removable semi-spherical golf club grip structure, substantially in the shape of a golf ball, with a dimpled surfae, that can be attached to the grip of a golf club and held in the hand of the golfer in order to give the sensation of holding a golf ball in the hand while putting or chipping. The sensation of holding a golf ball with a dimpled surrafce, in the hand while putting or chipping allows the golfer to judge how much force is necessary to apply to the putting or chipping stroke in order to cause a golf ball to travel a desired specific distance to the hole. When this training device is removed from the golf club, the sensation of holding a golf ball in the hand remains, imparting greater sensation and increased skill to the golfer while putting and chipping.

Abstract: A compressor includes a closed casing having a suction chamber and a discharge chamber. A rotating member is arranged in the casing and has a spiral bore extending along the axis of rotation of the rotating member. The bore has first and second end openings communicating with the suction and discharge chambers, respectively. A spiral internal member is inserted into the bore to rotate relative to the rotating member as the rotating member is rotated by an electric motor section in the casing. In conjunction with an inner surface of the bore, the internal member defines a plurality of closed spaces moving from the first end opening to the second end opening. A fluid in the suction chamber is transported from the first end opening to the second end opening while confined within the spaces, and is then discharged into the discharge chamber. The discharge of the fluid is controlled by a valve mechanism.

Abstract: One or more throttles are accommodated in a compression line and/or in a suction line to damp surges in reciprocating compressors. The size of the open cross-section of the throttle can be varied. The size is established to prevent surges from exceeding a prescribed limit.

Abstract: The invention provides a compact device for selecting the numbers to play in a game of chance, such as a lottery game. The device includes a number generator portion comprising a number wheel having a circumferential edge partitioned into segments, each bearing a different numerical indicia from the field of lottery numbers. A motor is connected to the number wheel so that when the motor is activated by a switch, the number wheel rotates about the motor axis. The number wheel and motor are contained in a housing having a window portion aligned so that only one of the numerical indicia of the number wheel is visible through the window at a time. By repetitive activation of the switch, a series of more or less random numbers will thus be generated. The housing can be configured so that it forms a relatively small, cylindrical barrel, suitable for attachment to a similarly-sized accessory portion such as a pen or flashlight.

Abstract: A spray pump for metered delivery of a liquid from a spray cylinder by means of a spray piston having a motor-driven screwed-shaft gear unit located in a housing, the movably supported drive element of which can be brought into engagement with the movable spray part outside the housing. To ensure that the smooth-running characteristics of the spray pump are not impaired by dirt on a threaded shaft of the screwed-shaft gear unit, the threaded shaft is arranged and supported inside the housing. Moreover, for this purpose the drive element is passed through the wall of the housing and is supported movably around its longitudinal axis in the housing for actuation of the coupling.
