Title: Improvements in or relating to friction clutches
Inventor: BLAND ALBERT NORMAN
IPC: F16D13/71
Filed: 1957-03-08
Abstract: 833,023. Friction clutches. AUTOMOTIVE PRODUCTS CO. Ltd. March 10, 1958 [March 8, 1957], No. 7799/57. Class 80 (2). A friction clutch of the type comprising a driving engine flywheel 14 and a pressure plate 12 biased to engage a driven disc 11 by springs 25, is disengaged by operation of radial throw-out levers 29 pivoting about pins 31 carried by rearwardly extending lugs fast with the pressure plate, the throw - out levers being formed with bulges 32 which, on movement of the levers, have an approximate rolling motion on abutment plates 33 adjustably secured to a cover - plate 17 enclosing the pressure plate and the driven disc. The abutment plates 33 are tapped to receive adjusting screws 41, and have tongues 35 at their inner ends engaging in slots 36 in the cover-plate. At their outer ends, the abutment plates 33 are forked and engaged ribs 34 on the cover-plate 17. Turning the screws 41 alters the axially positions of the fulcrum points of the throw-out levers 29 formed by their bulges 32 relative to the axis of the clutch, and hence enables adjustment to be made to take-up wear of the clutch linings. Blade springs 37, riveted at 38 to the abutment plates 33, bias the abutment plates radially outwards to engage their tongues 35 frictionally with the slots 36 and the cover-plate 17. The inner ends of the throw-out levers 29 are engaged by a thrust ring 42, and the usual anti-rattle springs 43 are provided. Bolts 15 pass through circumferential projections 18 formed around the cover-plate 17 to secure the cover-plate to the flywheel 14.

Patent GB-1569798-A (GB)
Title: Process for alkali-treatment of lignocellulosic fodder material
IPC: A23K10/32
Filed: 1977-02-25
Abstract: The increase of the feed value of lignocellulosic materials is achieved by treatment with an alkaline liquid and subsequent neutralisation using an acidic liquid in a closed system with circulation of the treatment liquids. The process liquids, during the course of the treatment, are fed at a rate corresponding essentially to the liquid absorption of the lignocellulosic material, as a result of which the amount of residue solutions obtained from the treatment are kept to a minimum. The alkaline and acidic liquids are fed in this case in the form of concentrates, while the water provided for dilution is fed separately at a rate corresponding to the liquid absorption of the lignocellulosic material. The process is carried out by using an apparatus having a distribution part (24) which is mounted on the top part of the vessel (10) and is suitable for feeding alkaline and acidic liquids and has an outlet for liquids, which exit from the lignocellulosic material, which outlet is mounted on the bottom part of the vessel. The apparatus also contains a pump collecting receiver (12), which is connected to the outlet, liquids and, possibly, likewise separately, water being fed to the receiver. The operating liquid is re-applied via a circulation pump (18) and a charging line (22). <IMAGE>

Title: Photographic Camera
Inventor: REIMANN HUBERTUS
IPC: G03B7/083
Filed: 1968-02-22
Abstract: 1,177,912. Photographic cameras. PENTACON DRESDEN KAMERA-UND KINOWERKE. Feb.22, 1968, No. 8671/68. Heading G2A. A photographic camera comprises an exposure control circuit including a photo-electric resistance and a variable resistance device, a switch operated by the control circuit, an exposure-time setting control element, means for simultaneously moving the control element and varying the resistance device, and an electromagnetically operated blocking member, controlled by the switch, for locking the control member. Fig. 1 shows one embodiment of the exposure control circuit, and in operation, manual pre-selection of the diaphragm setting varies the tapping 6 on a logarithmic resistance attenuator 3, in parallel with a battery 2, to vary the voltage across a potential divider comprising a photo-electric resistor 5 and fixed resistors 7, 8, 9 and thus to vary the voltage applied to the switch of the type which responds at a particular threshold valve and consisting of transistors 10, 11, thus producing a deviation away from the response voltage of the switch. Movement of camera release 15, moves, through slip coupling 16, the control member 17, connecting contact 18 to one of the fixed resistors 7, 8, 9, and simultaneously connecting contact 19 to one of resistors 20-22 to include this latter resistor in the exposure time determining circuit (not shown). Successive connections to resistances 7, 8, 9,moves the voltage applied to the switch towards the threshold valve and when this is reached electromagnet 12 is de-energized, releasing armature 14 to engage rack 17 which can then move no further. Release device 15 is then depressed further to release the diaphragm and then the shutter. The resistance assembly 20 .. 22 is slidable relative to the contact 19 to take account of film speed. Switch contacts not shown may be provided on the control element for lighting a warning lamp in its extreme positions to indicate that the illumination is outside the range catered for by the camera. In another embodiment Fig.2 (not shown) an impedance converter between attenuator (3) and photo-resistor (5) keeps the feed voltage independent of the photo-resistor valve, and temperature dependence of the threshold voltage of the switch is reduced by connecting a thermistor (26) in series with the attenuator.

In apparatus for lubricating the working cylinder of an internal combustion engine of the liquid fuel injection type as described in the parent Specification, an hydraulic column, preferably of lubricant, is interposed between the fuel-actuated plunger and another plunger which directly actuates the metering and delivery pumps. The fuel-actuated plunger 87 is disposed in a bore in a screwed plug 86, mounted in a casing 88, and its right-hand end is subjected to the pressure of fuel supplied through passages 83, 84, 85. The left-hand end of the plunger 87 carries a head 87a which abuts a head 92 of a plunger 91 acting upon the hydraulic column contained in a pipe line 89. A spring-loaded valve 96 is disposed between the plunger 91 and the pipe line 89 to ensure that the hydraulic column does not actuate the metering and delivery pumps until an adequate pressure value is attained. On the return stroke the hydraulic column by-passes the valve 96, which remains closed, through another valve 97 loaded by a light spring 97a. Any leakage of fuel past the plunger 87 passes out through a drain 93. Any loss from the hydraulic column is made up by a supply of lubricant through a pipe 94 and admission port 95 which is cut off on forward movement of the plunger 91.
