Abstract: 1298758 Two-part couplings; ceiling roses MK ELECTRIC Ltd 19 April 1971 [9 March 1970 12 June 1970] 11171/70 and 28957/70 Heading H2E An electrical connector, e.g. a ceiling rose, comprises a base to be secured to a surface, having live terminals (17, 19, Fig. 2, not shown) and an earth terminal 18 formed with resilient hook-shaped connectors 75, 76 and a resilient U-shaped connector (80) respectively, a cover 12 having terminals (42, 43, 44, Fig. 3, not shown) formed with connector pegs 88, 89, 90, and tabs (65, 66, 67, Fig. 4, not shown) on the base which interlock with pockets (72, 71, 73) on the cover to support the cover. On rotation of the cover with respect to the base the pegs engage the connectors and separation of the base and the cover in a direction normal to the plane of rotation is prevented. The base is formed of a part 10, which carries the terminals (17, 19), 18 and their associated connectors 75, 76, (80), and a part 11 which is screwed to and forms a shroud around the part 10 and has a wall 31 in which are provided apertures (81, 82, 83). Apertures (81, 82) each have a pear-shaped portion (84) and a narrow portion (85) and the aperture (83) lies over the earth connector (80). The pegs 88, 89 each comprise a shaft 92 and a pear-shaped head 91. The cover is attached to the base by passing the heads 91 through the pear-shaped portions of the apertures (81, 82) and then rotating the cover so that shafts 92 pass through the narrow portions of the apertures and heads 91 electrically contact and slightly close the hook-shaped connectors (75, 76) and mechanically engage the wall 31 thus additionally supporting the cover. Earth connector peg 90 passes through aperture (83) and electrically contacts and partially closes the U-shaped connector (80). Neither the connectors (75, 76) nor the terminals (17, 19) are directly aligned with any portion of the apertures (81, 82). In a second embodiment (Figs. 7-10, not shown) the connector pegs (104, 105) are substantially L-shaped each having arms (106, 107) and each formed of a single strip integral with its associated terminal (42, 43) respectively. Apertures (101, 102) in the wall (31) are also substantially L-shaped. Three metal plates (120) are secured to the cover (12) to define pockets (71, 72, 73), and a lead entering the cover is clamped between the members (114). The terminals are disposed unevenly around the device so that the cover will correctly fit with the base in only one position. The arrangement may be such that a relative linear motion between the cover and the base replaces the rotary motion to assemble the connector.

Title: Differential pressure regulator valve
IPC: F16H61/30
Filed: 1975-07-10
Abstract: 1467759 Valves; hydrostatic transmission control CLARK EQUIPMENT CO 10 July 1975 [14 April 1975] 29148/75 Headings F2V and F2W [Also in Division G3] A spool type differential pressure regulating valve 128 forming part of the control mechanism of a variable displacement swash plate pump 24 in the hydrostatic transmission of a fork-lift truck includes means to vary the bias on a spool of the valve when the truck brakes 50 are applied. The transmission comprises an internal combustion engine 18 driving a fixed displacement charge pump 22 and swash plate pump 24, the latter being connected via lines 32, 34 to hydraulic motors 26 driving wheels 12. The pressures on opposite sides of a restriction 92 in an output line 80 of charge pump 22 are communicated via lines 118, 120, regulating valve 128 and reversing valve 124 to opposite ends of an hydraulic actuator 100 controlling swash plate 42. Thus the output of pump 24 is normally proportional to the speed of engine 18. Valve 128 intervenes to vary the pressure relationship between lines 118, 120 and comprises a body 146 having inlet and outlet ports 150, 156 connected to the higher pressure line 120 and corresponding ports 152, 158 in the lower pressure line 118. A vent port 204 for leakage fluid is also provided. A hollow spool having lands 182, 184 is axially slidable within body 146 to control flow between ports 150, 156 without at any time restricting flow between ports 152, 158. The spool is urged rightwards by pressure in outlet port 156 communicated to its stepped left end 194 via spool passages 186, 176 in opposition to the pressure in outlet port 158 acting on its stepped right end 185, 189 via passage 157. The latter force is assisted by the bias of an internal spring 166 acting between spool land 182 and an abutment 168 on rod 190. The latter is fast with piston portions 164, 170 slidable in body 146 relative to the spool and biased leftwards by spring 202. Piston 164 can be acted on by the rod 200 of actuator 128 responsive via port 130 to the pressure in brake line 56. Should the brake pedal 53 be partially applied during travel of the truck, the actuator rod 200 urges piston 164 and rod 190 rightwards relative to the spool (Fig. 5 position, not shown) thus reducing the leftwards bias of spring 166. Consequently the pressure at outlet port 156 in line 120 falls relative to that at port 158 in line 118, causing swash plate actuator 100 to reduce the output of pump 24. Full application of the brakes causes actuator rod 200 to move piston 164 into abutment with spool land 182 (Fig. 6 position, not shown) to force the spool further rightwards. Thus land 182 blocks inlet port 150 but lower pressure inlet port 154 is connected via annular spool groove 180 to outlet port 156. The pressures in lines 120, 118 consequently equalize causing actuator 100 to set pump 24 to a zero displacement position.
