Title: Hydraulic reciprocating apparatus
IPC: F16H43/00
Filed: 1974-03-19
Abstract: 1501092 Hydraulic reciprocating motors KEELAVITE HYDRAULICS Ltd 19 March 1975 [19 March 1974] 12160/74 Heading F1A [Also in Division B4]  Hydraulic reciprocating apparatus for operating the rock breaking chisel of a percussive tool comprises a piston 3 resiliently biased in direction A and having opposed shoulders 7, 8, a housing 1 defining with the shoulders 7, 8 respective chambers 11, 12, and a valve 26 arranged to connect the chamber 11 alternately to a pressurized supply line 21, 22, 23 and to the other chamber 12. The resilient bias is preferably a gas cushion 5. The valve 26 includes a spool having one of its ends loaded by a small positioning piston 35 and its other end by a large positioning piston 34. As shown the piston 3 is just about to start a stroke in the direction B. The valve 26 is therefore held in its rightward position by the supply pressure in the line 21, 36 acting on the positioning piston 35, the other positioning piston 34 having been depressurized through a line 41, a port 14 uncovered by the shoulder 8, the chamber 12 and a passage 15 connected to a drain 15. Thus liquid from the line 21, 22, 23 flows through a line 24 to the chamber 11 and causes the piston to move. When a groove 10 in the piston 3 aligns with ports 13, 14, the line 41 becomes pressurized from a line 42 connected to the supply line. This causes the valve to changeover and inter-connect the chambers 11, 12 via lines 24, 27 whereby the gas cushion causes a stroke in the direction A. To inhibit cavitation more liquid is displaced from the chamber 11 than is received in the chamber 12, the excess being discharged to the drain 16. In alternative constructions the valve 26 is controlled by the pressure changes in the gas cushion 5 or by a pilot valve (31) responsive to pressure changes in the line 42, Fig. 1 (not shown).

Abstract: 1,066,171. Bundling-machines; endless conveyors. B. H. BUNN CO. March 24, 1964 [May 6, 1963 (2)], No. 12505/64. Headings B8A and B8C. A group of envelopes is made up into a bundle by compacting the ends and then tying a length of twine around the group whilst it is moving through the machine. In the embodiment one end of a group of upright envelopes 24, Fig. 2 (not shown), is forced between a vertical plate 69 and a leaf spring 72, which are carried by plates 70, 73 fixed to individual links of a conveyer chain 47. A rail 82 may be provided to limit the position of the bundle end. The other end of the bundle is compacted as it is forced against a spoke 91, Fig. 5 (not shown), of a braked wheel 27 by a vertical plate 79 also fixed to the conveyer. The twine is then fastened horizontally about the bundle as the wheel 27 is slowly pushed round. The bundle 28 is then released from the plate 69 and spring 72 (see also Fig. 8, not shown), and slides down a cam-plate 114 on to a table 30, from which it is pushed by an arm 132 (see also Fig. 11, not shown), towards a second tying machine. There the bundle is compacted by a clamp 141, Fig. 9 (not shown), while a cross-tie is made by rotation of a twine arm 143, Fig. 1, the finished bundle being pushed from the machine by the next oncoming bundle. The first tying machine has a twine arm 103, Fig. 1, rotatable about a vertical axis but the second machine may be of any type. The whole apparatus may be automatically controlled, and safety devices may stop the machine if there are no bundles or twine present. The conveyer chains 47, 48, Fig. 2 (not shown), are provided with guiding extensions 55, Fig. 8 (not shown), engaging the sides of the upper track. The return runs are supported by outwardly bent members 61 (see also Fig. 3, not shown), which engage with the upwardly bent portions 58, 59 of structural members 56, 57 extending the length of the lower track. The plates 70, 73, Fig. 2 (not shown), are fixed to the individual links of the chain so that as the chain goes round the sprocket the two plates will be separated, Fig. 8 (not shown), and the bundle released. The second conveyer chain 117, Fig. 11 (not shown), is provided with pusher arms 131, 132, each pivotally connected to a chain-pin. The abutment of cam-plate 149, Fig. 12 (not shown), on extended pins 150, 151 prevents rotation of the arm 132 during straight line movement, but allows the arm 132 to turn (see also Fig. 11, not shown), when the chain passes over the sprocket 119, and so leaves the bundle without giving it any additional impulse. Guides 135, 136 may be provided to give additional support to the arm supports.

Abstract: 866,052. Two-part couplings. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 2, 1958 [April 18, 1957], No. 12734/57. Class 38 (1). In a socket connector for receiving a printed circuit card, each contact is loosely located in a recess in the connector so that on application of the card any initial engagement between the contact and the printed circuit is light but continued movement of the card causes the contact to interact with a surface of the recess to produce movement of the contact portion of the contact transversely of the printed circuit into firm engagement therewith. Fig. 1 shows one embodiment wherein a corrugated portion 15 of the contact projects from the recess 13 therefor. The card 19 is inserted at an angle into a channel 18 and subsequently swung into its final position, where it is secured by a screw 21, such movement depressing the contact so that a bent-back portion thereof engages a surface 20 and produces full contact-pressure between portion 15 and the card. A similar construction is shown in Fig. 2 except that in this case the contact has a projecting endportion 23 which is engaged by a bracket 22 on the card as the latter is drawn into the connector. Such engagement causes flexing of the portion 15 into contact with the card. The portion 23 may be inclined so as to engage an inclined surface on the bracket (Fig. 3, not shown). Inclined surfaces may be provided on both the bracket and the connector body, as shown at 25, 24<SP>1</SP> in Fig. 4, so that the contact portion 15 is urged from both ends towards the card.
