Patent GB-1440057-A (GB)
Title: Air refrigeration apparatus
IPC: F25D21/04
Filed: 1975-05-06
Abstract: 1440057 Refrigerators CLARK EQUIPMENT CO 6 May 1975 [17 May 1974] 18934/75 In a refrigeration apparatus, e.g. a refrigerated display case 2, in which air is circulated by a fan 20 through a cooler 16, the air cooler 16 is provided with two air inlets 24, 28, the arrangement being such that when the inlet 24 is blocked by frost, the air enters through the inlet 28 thereby extending the cooling period between defrost cycles. As shown, air is withdrawn from the refrigerated space 4 by the fan 20 which passes the air from a plenum chamber 18 into a passage 22. From the passage 22, air normally passes into the inlet 24 of the cooler 16, but as frost builds up on the inlet 24, pressure builds up in the chamber 36 between the fan and the cooler and an increasing volume of air passes through a restriction 30 into a plenum chamber 34 thence into the second inlet 28 of the cooler 16. The velocity of the air through the restriction 30 is sufficient, when cooler inlet 24 is closed, to cause airborne frost to be thrown across the inlet 28 into a frost collecting cavity 32 as the air flow turns through 90 degrees into the inlet 28, thereby preventing this frost from blocking inlet 28.

Title: Hydrostatic servo-steering mechanism for the steering of automotive  vehicles and like machines
IPC: B62D5/093
Filed: 1972-04-24
Abstract: 1344449 Power steering VYZKUMNY USTAV STAVEBNICH A ZEMNICH STROJU 24 April 1972 [22 April 1971] 18953/72 Heading B7H A hydrostatic servo-steering mechanism for a vehicle, e.g. an earthmover, includes a power circuit 1 (shown in heavy lines) including a pump 3, a distributer valve 7 and a servomotor 10; a steering circuit 2 including an input pump 18 actuated by the steering wheel 20 and an output motor 30 connected to the steerable wheels 15, 151 and means for varying the steering ratio of the steering circuit 2. The steering ratio may be varied either continuously or in steps. In a first embodiment (Fig. 1) the input or control pump 18 is connected by steering lines 21, 22 and branch lines 24, 25 to the distributer valve 7 to control the flow of pressure fluid from the pump 3 to the servomotor 10. The steering lines 21, 22 are also connected by lines 28, 29 to the opposite ends of piston and cylinder output motor 30 which acts as a follow-up or feed-back cylinder. The motor 30 has a differential piston 31 which divides the cylinder 30 into three chambers 32, 33, 34. The central chamber 33 is connected by line 35 and selector valve 23 either to steering line 21 or 22. With the valve 23 in the position shown the chamber 33 is connected to steering line 22 and this arrangement provides a high steering ratio (i.e. a large number of turns of the steering wheel from lock to lock) which is suitable when the earth mover is being driven on the highway or in the event of a pump failure when the cylinder 30 acts as a telemotor. With the valve 23 in its second position the chamber 33 is connected to the steering line 21 to provide a low steering ratio suitable for use when the earthmover is in operation. The valve 23 may be shifted manually or may be automatically shifted from its second position to its first position should the pressure in either of the steering lines 21 or 22 rise above a predetermined value (e.g. in the event of a pump failure). In a second embodiment (Fig. 4) the steering circuit is provided with two feed-back cylinders 40, 40<SP>1</SP> which are connected to the steering lines 21, 22 by a selector valve 23<SP>111</SP> and again the two positions of the valve 23<SP>111</SP> provide a high (as shown) or low steering ratio. In a third embodiment (not shown) the feedback cylinder is a conventional double acting piston and cylinder and the steering ratio is varied by adjusting the effective length of the steering arm 14<SP>1</SP> by moving the connection with the piston-rod along the arm. The connection may be moved by a screw or by a pneumatic or hydraulic motor. In a fourth embodiment (not shown) the steering ratio is varied by varying the displacement of input pump 18. The pump may be a duplex pump having two constant displacement sections arranged in parallel and a selector valve is used to connect either one or both sections into the steering circuit. Alternatively the pump may be a variable displacement pump.

As shown, the figure comprises an upper part 1 carrying a club 25 and rotatably mounted on a rod 6 extending from a lower part 4. A waist part 3, also rotatable about the rod 6, is disposed between the upper and lower parts to which it is connected by oppositely acting springs 22, 19, respectively. In the normal " address " position of the club, a stop 18 on the waist part is held in abutment with a stop on the lower part by the spring 19, and a stop on the upper part is held in abutment with the stop 18 by the spring 22. The club is retracted by pressure of the finger on a projection 26 on the upper part, the spring 22 being thereby tensioned and the waist part remaining stationary. On release of the projection 26, the club returns to strike the ball, the momentum being sufficient to cause the waist part to rotate against the action of the spring 19 and allow the club to " follow through." In modifications, the rod 6 is fixed to the waist part and is rotatable in the upper and lower parts, and the projection 26 is replaced by a bell crank or geared operating device.
