Filed: 1963-05-09
Abstract: 972,754. Resilient mountings. ADAM OPEL A.G. May 9, 1963 [May 19, 1962], No.18457163. Heading F2S. [Also in Division B7] A resilient pivotal mounting 20 for attaching to a vehicle both a support tube 17 extending rearwardly from an engine and gear-box assembly and a tubular forward extension 22 of a rear axle 23 provides for resiliently constrained pivotal movement of the axle assembly 23 and the engine assembly about a transverse axis through the mounting 20, for resiliently constrained transverse displacement of the axle extension 22 with consequent entrainment of the rear end of the engine support tube 17, and for resiliently constrained rotation of the axle extension 22 without entrainment of the rear end of the engine support tube 17. A member 82 (Fig. 4) mounted on the vehicle frame carries a transverse pivot bolt 80 supporting the inner sleeve 69 of a rubber bushing 70 which is provided with fore and aft cavities 71 to provide greater resilience horizontally than vertically and has an outer sleeve 68 secured by eyelets 72 and bolts 61 within an arm 21 attached to the axle extension 22. Also attached to the arm 21 by the bolts 61 is a flanged member 54 (Fig. 6) carrying rubber bushings 55 supporting connecting pieces 50 adjustably secured by bolts 51 to a sleeve 42 mounted on the engine support tube 17 by means of rubber blocks 41 (Fig. 5) ,which yield only to a limited extent longitudinally of the tube 17 but to a greater extent in the peripheral direction to prevent rotation of the axle extension 22 from being transmitted to the tube 17. A propeller shaft 18 coupled to the engine by a sliding joint (not shown) extends through the support tube 17 and is connected by a cardan joint 35 to a rear axle input shaft mounted by means of a ball bearing 96 within the axle extension 22. Each end of the axle 23 is connected to a shock-absorber 37 and carries a cantilever arm 34 pivotally connected to a spring 30. In another embodiment (Figs. 8, 9, not shown) the mounting is constructed as a resilient universal joint which encloses the cardan joint 35 and comprises an annular rubber bushing of segmental crosssection disposed between concentric members terminating the support tube 17 and the axle extension 22, and a recessed annular bushing disposed between the end of the support tube 17 and a surrounding annular member on the vehicle frame.

Title: Improvements in or relating to mixing valves for use with oxygen blowpipes for welding and cutting metals
IPC: F23D14/38
Filed: 1944-09-27
Abstract: 590,794. Rotary disc valves. HANCOCK, L. J., and CUMBER, W. F. Sept. 27, 1944, No. 18505. [Class 135] A gas mixing valve for use with oxygen jet cutting or welding burners to mix a gas of high calorific value with a gas of low calorific value comprises two separate inlets 7, 8 for the gases to be mixed, a mixing chamber 4, a seating member 3 with a set of ports 22 communicating with one inlet 8 and another set of ports 23 communicating with the other inlet 7, and a rotary disc valve 10 with two corresponding sets of ports 22a, 23a, a port of each of the latter sets registering simultaneously with a corresponding port in the seating member 3 to provide, in different rotary positions of the valve, a different pair of passageways communicating with therespective inlets. The proportions of the mixed .gases are different for each pair of passageways but remain, constant during the opening or closing of any individual pair of passageways because the angles subtended at the centre of the valve disc by the two pairs of registering ports are the same. To compensate for the different densities and pressures of the gases, one of the ports of a registering pair of ports may be longer in a circumferential direction than its mating port so that this pair opens before or closes after the ports of the other passageway of the pair. As shown, the valve disc 10 is mounted in a housing 1 with a central bore containing a bearing 12 for the valve spindle 11, a gland 13 and a spring 14 pressing the valve disc 10 against the seating member 3. The latter is clamped to the housing 1 by screws passing through a block 5 having passages 19, 20 connected with the inlets 7, 8 for the gases of low and high calorific value respectively. The passages 19, 20 open respectively into an annular groove 18 and a central recess 17 in the seating member 3. A groove 24 permanently connected to the atmosphere by a passage 25 prevents the leakage of the higher pressure gas into the lower pressure gas. The groove may be in the valve disc as shown or in the seating member or in both. The ports 22 open into the recess 17 and the ports 23 into the groove 18. The ports 22a, 23a are arranged in pairs, a port 22a and a port 23a along four radial lines, Fig. 5, so that only two pairs of ports are in register in any one position. The proportion of the mixed gases is indicated on a disc 32 on the spindle 11. The markings on the disc 32 are visible through an opening in a plate 30 closing a housing 29 containing the worm and worm wheel 16 by which the valve is operated. According to the Provisional Specification, one of the passageways may be arranged to close slower than the other by drilling one hole nearer to or farther from the centre of the valve.

Abstract: 1,017,158. High vacuum pumps. MAXPLANCK-GES ZUR FORDERUG DER WISSENSCHAFTEN E.V. May 10, 1963 [May 15, 1962], No. 18549/63. Heading F1N. In evacuating a vessel 1 Fig. 1 (not shown) by condensation of residual gas on the surface of an element 2 cooled by refrigerant e.g., hydrogen or nitrogen admitted through a line 3 and withdrawn as vapour through a line 4 by a vacuum pump 6 the temperature of the element 2 is maintained sufficiently high for the condensate to be at least partly in crystalline form the thermal conductivity of which is greater than that of condensate in amorphous form. Pumping rate tends to decrease with increasing thickness of condensate layer and is maintained by periodically decreasing the temperature level of element 2 from an initial value sufficient to maintain constant the surface temperature of the condensate at a predetermined optimum level. Initially this temperature level is maintained by a regulating valve 5 in vapour line 4 being controlled by a temperature responsive means 8 and an indicator 9; the valve 5 having an adjustable by-pass which during closure periods of valve 5 allows sufficient vapour flow to maintain the element temperature a fraction of a degree above the required level. As pumping proceeds and a layer of condensate is built up a timer 10 periodically opens valve 5 to a lower reference temperature level and also further opens the by-pass 11. In a modification pumping rate is maintained by an electric pressure gauge 14 Fig. 2 (not shown) which sends pulses through a bridge circuit 12 to effect periodic adjustment of the setting of valve 5 and by-pass 11. At each setting valve 5 is controlled by means 8, 9.

June 27, 1931, No. 18627. [Class 1'32 (ii).] A method of applying a grip, distensible by fluid pressure, to the shaft of a sporting or other implement, or for removing the grip therefrom, comprises placing the grip 8, Fig. 8, within a tube 6, folding an end of the grip over an end 7 of the tube and reducing the pressure in the space between the grip and the tube. The shaft 4 is then inserted into the distended grip and the pressure between the tube and grip returned to atmospheric to allow the grip to contract and embrace the shaft. As shown in Fig. 9, the tube 6 is evacuated through an orifice 9 by a vertical hand pump 10. Other types of pump such as a filter pump or a hand-operated short-stroke pump may be used. The tube may be removably attached to the pump and the connection may incorporate a non-return valve 16, Fig. 13, of ball or other type. In the event of the grip being open at both ends; a tube such as that shown in Fig. 13 is used, the two ends of the grip being folded over the ends of the tube.

[Also in Division F4] An apparatus for cooling downflowing water by means of upflowing air comprises a cylindrical housing 1 within which are arranged a central vertical pillar 10 securely attached to a base plate 30 by means of a support frame 2 and having concentrically attached thereto in descending order a top cover 9, at least two spray nozzles 8 spraying a contact layer 6 supported above at least two fans 4 each provided with a screen 5 and mounted in a ducting 12 within a liquid sump bath 3. The water to be cooled is supplied through a pipe 21 and the central pillar 10, serving as a rising main, to a distributor 7 and then to distributor pipes 26 fitted with spray nozzles 8 slightly inclined to the vertical so that the spray regions of adjacent pairs of spray nozzles overlap to form an elliptical spray area on the contact layer 6. Six spray nozzles may be employed to give a substantially circular spray area 28 (Fig. 2 not shown). The cooling air which is sucked through a vertical filter 29 around the outside of the support frame 2 before reaching the fans 4 passes through the contact layer 6 and escapes from the housing through the top cover 9 comprising of alternate strips of flat and corrugated synthetic resin material spirally wound so that any water entrained in the upflowing air is deposited thereon and also to prevent any light from entering the apparatus, thus reducing the rate of growth of algae. The strips may be between 60 and 100 m.m. in width and the corrugation between 10 and 20 m.m. in height. Alternatively the top cover may be formed of honeycomb plates of the same material. Each fan, embodiments with three and five are described, may be independantly controlled, and when not in use may be sealed from the housing 1 by lowering the screen 5 on pillars, 14. The screens 5 have upturned and downturned lips 15, 19 to prevent interference of the air flow by the water, any water collecting on the screen may be discharged at discharge points 16 adjacent the housing wall 1. To maintain a constant amount of liquid in the system to which the apparatus is connected a float valve 24 and an overflow pipe 25 are fitted to the liquid sump bath 3. In an alternative embodiment the contact layer 6 includes a tube coil through which a liquid to be cooled is passed and the water is pumped on a closed circuit to trickle over the coils and cool the liquid therein, the cooling action of the water being increased by the partial vapourisation of the water by the cooling air.

Abstract: 1,187,473. Feeding record tapes. K. DIEHL. 25 April, 1967 [26 April, 1966; 11 Aug., 1966], No. 18959/67. Heading G5R. Digital signals are read from two tracks (e.g. an information track and a synchronizing track) of a tape by two independent heads which are mutually staggered by a distance less than that by which corresponding marks in the two tracks are mutually staggered. In the embodiment described, the tape is wound from one spool to another and then automatically rewound on to the first spool. As shown, a friction wheel 12 driven by an electric motor 17 drives a first spool 7 which takes up a record tape 20 until the unwinding of the tape from a second spool 6 causes the friction wheel 12 to be moved into engagement with the second spool 6 which thereupon reverses its rotation and rewinds the tape 20 until the unwinding of the tape from the first spool 7 causes the friction wheel 12 to be disengaged from the second spool 6 and held in a disenengaged intermediate position by a detent 80. As shown, unwinding of the beginning of the last turn of tape 20 from spool 6 releases a pin 27, allowing a lever 21 to swing under the action of a spring 25 so that a lug 23, as the spool 6 continues to rotate, strikes a stop 37 on an arm 33 forming part of a linkage 33, 36, 35 which is thereby caused to swing an arm 15 to transfer the friction wheel 12 from spool 7 to spool 6. A similar operation initiated by the release of a pin 28. from spool 7 brings about the disengagement. of the friction wheel 12 when rewinding is almost completed. The perforated tape 20 is of metal and is read by means of a lamp 61 and photodiodes 64, 65, 66, which are staggered (Figs. 2 and 4), one track 68 being scanned during forward movement of the tape and a. second track 69 during reverse movement. The central track 67 is used for synchronizing. The photodiodes 64, 65, 66 and the lamp bulb 62 are controlled by the arm 33 through switches 70, 75. A V-shaped portion 44 of a spring-loaded lever 41 urges the linkage 33, 36, 35 towards either of its extreme positions.
