The blade 86 is actuated by an external front handle 105 on a bellows-sealed axially-movable shaft 104 and has a snap-in locking protuberance 150. The blade 86, Fig. 7, moves between upper and lower guide surfaces, on an inlet port assembly which incorporates a two-part segmental valve body 120, 122 and an elastomeric seal 98 whose lips 110, 108 respectively engage the lower end of the bowl and the upper face of the valve blade 86. Flush water held in a tank surrounding the bowl is pumped manually to a vortex spray nozzle (38, Figs. 2, 6 not shown) by a bellows pump (40), the water conduit including an air cushion pocket (48) to provide a smooth flow. In order to clamp the upper and lower sections 14, 12 together, the seat section 14 has on its underside, Figs. 3, 4 (not shown) a pair of slidably-mounted parallel straps (82) actuated by a common handle (58) and having key-hole apertures (72) and ramps (74) which cooperate with raised screw heads (94) on the holding tank section 12.

The platform 19 is divided into stalls 112 by radial arms 57 rotatably mounted on a hollow vertically extending central pipe 31 which is supported from below and by arms 36 attached to enclosure 12, and which houses a wash line 37, milk line 39 and vacuum line 41. A collar 51 with radially, outwardly directed pipes insertable in arms 57 is provided on, and is rotatable about, pipe 31. Circular L-shaped angle irons, downwardly directed arms and further horizontally extending pipes together with the arms 57 comprise a frame structure 50 which is rotated by motor means 97 via a frictionally engaged chain 95, causing the cows to walk slowly around the platform 19, while being milked, from ingress point 133 to egress point 134 and thence through gate 136. The frame structure 50 is further supported on rollers by one of the circular L-shaped angle irons which engages on its vertical side with further rollers to provide a horizontal stabilizing force. The outer parts 111 of frame 50 are pivotable from their first position shown in Figure 1 to a position which allows more access for cleaning purposes. The position of the feed trough 25 permits a cow to turn its head to feed thus reducing the amount of space required. A dribble trough 135 is provided to catch food falling from the cow.

Abstract: 1533654 Hydraulic valve gear BRITISH LEYLAND UK Ltd 3 Dec 1975 (22 Nov 1974] 50616/74 Heading F1B [Also in Division F2] A self-adjusting I.C. engine inlet valve hydraulic tappet assembly is constructed to provide a controlled amount of lost-motion between the tappet assembly and the inlet valve 15 so as to vary the lift imparted to the valve 15 from a cam C in response to the engine speed and the viscosity of the oil in the tappet assembly during engine operation. The tappet assembly comprises a cam engaging first tappet member 24 slidably supported in a control sleeve 26 and having a bearing support wall 23, 22 slidably supporting a second tappet member 21 maintained in contact with the end 20 of the inlet valve 15 by a spring 25, the support wall 23 forming an enclosure 30 between the tappet members 24, 21. Inlet and outlet ports 29, 28 in the tappet 24 are arranged to co-operate with rectangular and triangular inlet and outlet orifices 31, 32, in the sleeve 26 which has a toothed flange 33, 34 and is turnable about its axis 1 by a control regulating rack 35 linearly displaceable by a throttle linkage (not shown), each turning movement of the sleeve 26, in response to the engine throttle setting, serving to vary the height of the triangular outlet orifice 32 to thus vary the exhaust rate, to an outlet duct 38, of the engine oil fed to the enclosure 30 from an engine oil source i.e. inlet plenom 41, one-way valve 24, duct 40 and inlet port 29, such variations of the exhaust rate automatically varying the lost-motion within the tappet assembly and hence the valve lift and opening period. The rack 35 additionally has a tapered restrictor 37 which enables flow from the output duct 38 into a return plenom 39 to be regulated, the narrow end of the restrictor 37 serving at low engine speeds to restrict oil flow from the enclosure, whilst, at higher engine speeds, the wider end of the restrictor 37 is interposed in the exhaust oil path to allow unrestricted flow of such oil as does escape from the enclosure 30. Increased oil leakage from the tappet assembly due to reduced oil viscosity at elevated oil temperatures is compensated by a thermal device which is responsive to the oil temperature in or near the enclosure 30 and acts to further move the rack 35 appropriately adjust the valve lift accordingly. The regulating rack 35 may be used as an engine speed regulator in place of the usual carburetter butterfly type throttle valve, all throttling being undertaken by the variable inlet valve lift.

Abstract: 1,202,917. Protective arrangements. ELEKTROPHYSIKALISCHE ANSTALT BERNHARD BERGHAUS. 8 Nov., 1967 [9 Nov., 1966], No. 50779/67. Heading H2K. In a protective arrangement for a glow discharge apparatus used for metallurgical processes, an auxiliary electrode is provided in addition to the main electrode or workpiece, a change in the ratio between the currents supplied to the electrodes producing a control signal. As shown, the currents I s , I w  to the auxiliary and main electrodes (not shown) cause voltage drops U s , U w  across series resistors 5, 6. These voltages are applied differentially through a resistor 11 across the base-emitter circuit of a transistor 10. In the event of arcing, the voltage U w  increases relative to the voltage U s , and the transistor 10 conducts to operate a relay 12 or to provide an output voltage V A . The relay 12 may effect a brief disconnection of the supply to the apparatus and if the disconnections are frequent, the final interruption of the supply occurs. If the circuit of the auxiliary electrode becomes defective, the blowing of a fuse in that circuit ensures operation of the protective arrangement. For a three-phase apparatus the arrangement described above is triplicated.
