Patent GB-936197-A (GB)
Title: Fluid motor mechanism
Inventor: STELZER WILLIAM
IPC: B60T13/24
Filed: 1961-03-28
Abstract: 936,197. Fluid pressure brakes. KELSEYHAYES CO. March 28, 1961, No. 11259/61. Class 103 (1). A fluid pressure servo-assisted braking system includes a fluid-pressure motor in which there is provided a resilient reaction element 80 (Figs. 2 and 4), between a manually-operable member 49 which is adapted to operate a valve mechanism 51 which normally balances pressures on opposite sides of a pressureresponsive unit 30 and is operable to connect a variable pressure chamber 64 to a source of pressure different from the atmosphere; the resilient element 80 being acted upon by a reaction member 91 fixed to the manuallyoperable member 49 and a portion 86 of the pressure responsive unit to transmit reaction to the manually-operable member to resist valve operating movement. The pressureresponsive unit comprises a stamped annular shell 31 and a co-operating diaphragm 33 clamped at its outer periphery 34 against the casing sections 11, 12 at its inner periphery 36 by a plate 37 against the shell 31. In the inoperative position shown, valve 51 is closed against the seat 50 on manually-operable member 49 attached to operating rod 46 to permit vacuum present in chamber 66, leading to a vacuum source via connection 67, to be transmitted via passages 69, 70, 62, 63 to variable pressure chamber 64 to the right of diaphragm 33. When the pedal 48 is depressed, push-rod 46 is moved to the left to move manuallyoperable member 49 until the valve 51 engages the seat 59 so that the valve elements are in a lap position. Further movement of member 49 lifts valve seat 50 away from the valve 51 to permit air to flow from ports 75 around the valve seat 50 and through passages 62 and 63 into the variable pressure chamber 64 to initiate movement of the pressure-responsive unit 30 and move axial member 18 to the left and moving hydraulic master cylinder plunger 23 to the left to pressurize the line 26 to the wheel brake cylinders 27 of the vehicle. In the lap position of the valve elements the flange 90 of reaction member 91 will lightly engage projection 83 (Fig. 4), on the resilient element 80 and further movement will slightly deform the projection 83 without appreciably resisting movement of the manually-operable member 49. Increased movement of member 49 causes the resilient element 80 to be engaged fully by flange 90 and permits reaction to the brake pedal proportional to the force being exerted by the pressure responsive unit. Flange 86 on hub 40 of the pressure-responsive member also bears against the reaction member and the flange 86 also co-operates with a flange on the axial member 18; there being a slidable connection between the member 31 and associated elements of the pressure-responsive member 30 relative to the flange 78 of the axial member 18. Specification 846,211 is referred to.

Abstract: 698,330. Counting-apparatus. SIMON (HOLDINGS), Ltd., H. Aug. 30, 1950 [May 15, 1950], No. 12035/50. Divided out of 698,323. Classes 106 (i) and 106 (iv). Means for recording the relationship between the output of a product of a cereal mill and the input to or the total output of the mill, comprises a number of weighers for weighing equal batches of the output product, each adapted to deliver an electrical impulse after a batch has been weighed, means for totalizing impulses from all the output product weighers and advancing a counting mechanism in accordance with the sum, means for delivering electrical impulses after specified numbers of equal batches of total output or of input material have been delivered, and printing mechanism adapted to be brought into operation by the last-mentioned impulses to print the total then indicated by the counting mechanism, thereby recording the amount of output product in relation to the total output or the input. In a first embodiment, a standard grain input weigher, set to make predetermined weighments, discharges at approximately regular intervals, actuating through a striker 10 a tentooth ratchet-wheel 11 driving a disc 12 through a 1 : 10 Geneva gear. Thus, contacts tl are closed once per hundred weighings. Standard output weighers, one for each flour stream, are set to make weighments of one-half the input weighments ; at each discharge a striker 13 on the weigh bucket release mechanism closes contacts o1 and completes a circuit through a magnet CM, thereby, driving through pawl-and-ratchet means a printing counter 14. Differential gears 19 provide for summing the impulses from a plurality of output weighers, and the total registered on the counter 14 is printed when the contacts tl close after each 100 input weighings, the indication being arranged to represent directly the percentage extraction. The counter is automatically zeroized after each printing. A slow-acting relay C serves to disconnect the apparatus from the output weigher in the event of a fault developing ; it also operates audible and visual alarms. In another embodiment the percentage relationship of a particular type of finished product to the total output of all finished pro. ducts of a cereal mill is recorded, the printing being effected after delivery of a certain number of batches of the whole output.

Abstract: 1380766 Inhalers H HIRTZ and H-J HIRTZ 15 March 1972 [7 Dec 1971] 12103/72 Addition to 1310949 Heading AST [Also in Division E2]  A device for treating a patient's respiratory passages with warm air substantially as described in the Specification 1310949 in which a first assembly comprising a mask 20 and a reservoir 28 is withdrawable from a second assembly comprising a heater 22 and at least one outer wall 32. When assembled the heater 22 and the reservoir 28 surround a chamber 40 upstream of the mask. The reservoir 28 is concentric with the heater within the outer wall. The reservoir is a hollow cylinder of porous rigid material e.g. lime sand stone, pumice stone, a filtering stone or a ceramic and is fitted at one end with a plastics ring 51 which has projections 52 which form a first bayonet joint with recesses 48 in an intermediate member 45 forming part of a chamber 21 attached to the mask. Inner wall 31 and the outer wall 32 are releasably interconnected and connected to the intermediate member by a second bayonet joint construction Figures 5 to 9 (not shown). The heater 22 is attached to the inner wall 31 by a member 39 so that when the intermediate member and the inner wall are rotated to release the second bayonet joint the reservoir still attached to the intermediate member can be removed from around the heater. The reservoir can then be replaced or replenished with water or medicating liquid from a separate container (76) (Fig. 12 not shown). As the inner wall is rotated to release the bayonet joint electric supply contact pins 25 attached to a holder 70 operatively connected with the inner wall are rotated relative to a plug receiving socket 71 in the outer wall so that if a plug 26 is inserted it cannot connect with the pins. In use the air to be inhaled is drawn through apertures 35 in the base of the outer wall into an annular passage 34 between the outer and inner walls, through apertures 36 in the inner wall 31, over the reservoir and through apertures 37 in the member 39 into the chamber 40 where it is warmed to the desired temperature controlled by a thermostat 27 as it passes to the mask. An elastomeric seal 53 is fitted between the assemblies.
