Title: Improvements in printing, gumming or like mechanisms
Inventor: WELVAERT CLAUDE ALEXANDRE CHAR
IPC: B41F33/04
Filed: 1958-02-20
Abstract: <PICT:0897364/III/1> A gumming mechanism comprises a driven roller for feeding a layer of gum or paste contained in a bath, an applying roller rotatably mounted on a pivoted arm spring-urged towards applying position and engaged by a pad engaging an article to be gummed, a transfer roller oscillating between the feed and applying rollers and freely mounted on a pivoted arm spring-urged to carry a cam follower into engagement with a rotatable cam for oscillating the arm, a hook member adapted, on movement of the applying roller arm away from applying position, to engage a projection on the cam-operated arm to restrain it from oscillating movement, and a solenoid responsive to the action of an article-responsive detecting member for causing such pivotal movement of the applying arm in the absence of an article.  On rotation of the gumming-roller 17, a cam 43 oscillates the transfer roller 38 between the fountain roller 44 and the applying roller 24.  On detection by means not shown of the absence of a carton 11 to be gummed, a solenoid 32 is energized to rotate an extension 29 of an arm 26 pivoted at 27 and supporting the roller 24, so that the latter is moved out of contact with the roller 17.  Consequently, a hook 56 on a member 53 pivotally mounted on the axis of the roller 24, and spring-urged against a stop 54 on the arm 26, is moved into engagement with an extension of the spindle 57 of the roller 38 to prevent the oscillation of the latter.  The fountain roller 44 also ceases to rotate, being normally driven stepwise by a pawl 47 pivoted at 48 to the lever 39 carrying the roller 48. If the hook 56 moves into latching position before the spindle 57 is in such position, the latter snaps into place by forcing down the hook against its spring.

Title: Improvements in sheet dispensers
IPC: G03B17/26
Filed: 1964-02-11
Abstract: 1,039,644. Feeding sheets. W. ZINDLER, [trading as LUMAPRINT ZINDLER KOMMGES.]. Feb. 11, 1964 [Feb. 25, 1963], No. 5568/64. Heading B6B. In apparatus for dispensing light-sensitive sheets of paper from a closed container, the latter is closed by a second container for other sheets and which is slidable on the first container and has a pivotal connection therewith. To dispense a sheet, the second container 2 is slid rearwardly over the closed container 1 against the action of a spring 24 to cause a roller 35 to roll over the pile of sensitive sheets, and on the return movement of the container 2 by the spring 24, the roller 35 is locked against rotation and forces the top sheet of the pile along a ramp 8 and through a slot which formed by the temporary further separation of edges 9 and 15 on the containers 1 and 2, respectively. The functional parts causing the sheets to be dispensed are carried by the removable container 2. The container 1 has a base 3, side walls 4, and a rear wall 6; and the container 2 has a top wall 16 an intermediate wall 10, side walls 11, a rear wall 13, and a front wall 14 having a lip 15 which extends inside the container 1 to overlap the ramp 8 and is spaced slightly from the edge 9 to leave a small gap which does not allow light rays to enter the container 1. The roller 35 has an elastic covering and is rotatably mounted on an arm 33 pivoted at 32 in a recess 51 in the plate 10, and a pawl 36 bears on the roller at an angle thereto such that the roller can rotate in a clockwise direction, but is wedged by the pawl which digs into the roller surface to prevent counterclockwise rotation. An extension 41 of the arm 33 is engaged by a push-button 42 in the plate 10 so that the roller 35 can be raised. The top container 2 has an opening 17, which is normally closed by a slidable cover 18, to allow insertion and removal of sheets of positive emulsion paper. The intermediate wall 10 of the container 2 has rollers 29, 30 which roll over the top edges 31 of the walls of the container 1, and brackets on the wall 10 support a rod 22 on which is displaceable a catch device 25 which is urged by the spring 24 to engage a recess in the rear wall 6 of the container 1 to form a hinge connection.

Title: Improved automatic control for electrical heater circuits
Inventor: WALLACE JOHN VIPOND
IPC: G05D23/24
Filed: 1953-02-27
Abstract: 742,726. Automatic temperature control systems; automatic regulators. NAPIER & SON, Ltd., D. Feb. 18, 1954 [Feb. 27, 1953], No. 5627/53. Class 38 (4). Aircraft de-icing heaters 14 are connected through contacts 11 to a D.C. or A.C. supply when a relay 24 is energized by operation of a manual switch 21. Under these conditions a winding 15 of a carbon pile regulator 16 is connected across a shunt 13 in the heater circuit so that a bridge circuit including regulator 16 renders a rectifier 30 conductive to shunt the bridge output. But heater resistance rises with increase of heater temperature, thus reducing the energization of winding 15 until, at the predetermined temperature, the bridge output polarity reverses and rectifier 30 is non- conductive. Relay 31 is then operated by the bridge output to de-energize heaters 14 through relays 37 and 24. A relay 46 is also de-energized by contacts 45 of relay 24 to connect a second winding 41 of regulator 16 in series with heaters 14 in a high resistance circuit across the supply. The current in this circuit, which is too small to cause appreciable heating, rises as the heater temperature falls until, at a predetermined temperature the bridge is balanced and the heaters switched on again. Heater temperature is thus maintained between two limits. A carbon pile regulator 27 in the bridge circuit responds to supply voltage and compensates for variations of the latter. A carbon pile regulator 42 responds to the voltage across the heaters during cooling and maintains that voltage constant to increase the corresponding current change in winding 41. A suitable construction of carbon pile is shown in Fig. 2 in which the carbon stack 16 is housed in a tubular armature 53 mounted on flexible spiders 54, 55. Windings 15 and 41 act on the armature in opposition to a spring 64 the forcedeflection characteristic of which is adjustable by a threaded core 66. Pile contacts 51, 52 are connected to lead 62 and the casing respectively.

Abstract: 936,090. Air filters. VOKES Ltd. Feb. 15, 1962 [Feb. 15, 1961], No. 5677/61. Class 8(2). Prevention of rise in oil level due to sludge collecting at the bottom of the bath 9 of an oil-bath air filter is effected by a vertical overflow pipe 22 discharging into a reservoir 10 beneath the bath 9 and means is provided whereby this overflow is modified during periods of fluctuating air flow and hence of fluctuating oil levels. To this end the upper end of pipe 22 is covered by an inverted pot 21 surrounded by a central tube 3 having oil drain holes 25 below its closed upper end and which serves to support an upper annular filter element 4 and two lower elements 5, 6 within a casing 1. The air space near the upper end of pot 21 is connected to the air space just below element 6 by a tube 23, the air space of reservoir 10 and a tube 18. In operation dust-laden air is drawn through an annular inlet defined by lips 8, 11 of the casing 1 and results in a fall in oil level in that portion of the bath 9 surrounding the tube 3, from 24 to 27 or 28 according to air flow. This is accompanied by a rise in oil level to 27 or 28 within the tube 3 caused by suction therein and this oil is prevented from gaining access to the overflow pipe 22 by the pot 21. The oil bath is secured to the casing by adjustable support struts 19 and the elements 5, 6 are adjustably clamped to the tube 3.

Abstract: 1,240,053. 053. Accelerometers. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Feb.4, 1970 [Feb. 4, 1969], No. 5865/69. Heading G1K. [Also in Division F2] Apparatus sensitive to a change in the speed of a shaft 18 includes a body 12 rotatable by the shaft through a resilient connection 13 twistable to displace the body along its axis of rotation upon a change in the shaft speed. A half-coupling 11 is mounted on an axle 18, whose rate of change of angular velocity is to be measured, and is connected by three resilient fingers 13 to a half-coupling 12 with a conical extension free to move axially in a complementary conical recess in the half-coupling 11 under the control of the resilient fingers 13. The fingers 13 may be stamped from a resilient metal such as beryllium copper or stainless steel and rivetted to the half-couplings or they may be of rubber or plastics and bonded to the half-couplings, Alternatively a rubber tube with skewed slots may be clamped to the half-couplings. The halfcoupling 12 is preferably formed as a fly-wheel with the mass concentrated symmetrically round the periphery. Axial displacement of the half-coupling 12 is sensed by three-port valve, the size of the exhaust port of which is controlled by a ball 25 carried by a cup 27 on a cantilever spring 26 on which a push rod 17 bears so as to transmit any axial displacement of the half-coupling 12 which is thus converted into a corresponding change of pressure at an outlet port 23. The range can be adjusted by moving a jet block 24. The outlet pressure can be used to control a vehicle braking system in relation to deceleration or alternatively when slip occurs.

Abstract: 1392173 Electro-chemical analysis TECHNICON INSTRUMENTS CORP 7 June 1972 [9 March 1971] 6378/71 Heading G1N Oxygen (or other electro-chemically-reducible gas) is determined by passing the gas stream through a POROUS CATHODE immersed in an electrolyte and measuring the current in an external cell. By adjusting the gas pressure in the porous electrode from 0.1# 2 atmospheres a range of 7 p.p.m. to 100% may be detected. Cell Construction. As shown Fig.1 a pump 4 feeds gas through a conduit to two cathode elements 5 in an electrolyte tank 1. The cathode elements may be a porous silver nickel alloy. The gas exits through a restrictor 6. A platinium anode 9 is housed in compartment 10 so that free oxygen is not liberated into the tank. A mercury/mercuryoxide reference electrode 11 is housed in another compartment. The electrolyte may be 20% KOH solution. Circuit Fig.2. The voltage difference between reference electrode 11 and a reference source 22 controls an operational amplifier 20 and booster amplifier 21 to energize the anode 9. Series dropper 23 is connected to a recorder 24. Residual current effect may be compensated conventionally by a second working electrode (not shown) to back off the residual current or by pulsed current techniques. Applications. O 2  may be stripped from e.g. river water or sewage by an inert carrier gas. It may also be used for indirect measurement where organic material is oxidized by permanganate or dichromate and the excess oxidant then reacted with H 2 O 2  to liberate O 2 .
