Tape BB is secured by spring contacts A mounted in insulated spring loaded block B. The block is mounted on an eccentric pivot C to allow its position to be adjusted. One end of each contact is attached to a printed circuit board and the other end contacts a metal spring plate D mounted on an insulating board K. A sprocket drum J is coupled to a ratchet wheel N prevented from moving clockwise by wire spring P. A pawl Q engages a tooth of the ratchet under the action of springs (not shown). The pawl is slidable horizontal and has an L-shaped cut-out V. A rotary disc Z has a pin AB received in the cut-out to engage shoulder AC of the cut-out to move the pawl to the right in Fig. 1. The pawl is moved one tooth position and is spring loaded to engage the next tooth on the ratchet before the pin is released from the shoulder. The pawl then moves to the left to rotate the sprocket drum and this movement may occur at a rate as slow as once per day.  A perforation position on each row of the data is used for position sensing. Each pair of rows forming a word may have holes for one word and no holes for the adjacent word or may have one hole and no perforation. The sensor either detects equality i.e. both holes or no holes, for correct positioning or detects inequality.

Abstract: 1502010 Endless and rotary conveyer systems; feeding objects and wrappers together CARLE & MONTANARI SpA 31 Dec 1975 [3 Jan 1975] 53382/75 Headings B8A and B8C Bars S of soap in holders 1 on a conveyer belt A, are picked out of the holders by pairs 3 of grippers on a rotary elevator B. At the top of the travel of the latter, grippers 34, 35 lift the block out of the grippers 3 and carry it parallel with the movement of carriers on a conveyer D. As the block is rising on the elevator B a suction rod 25 picks up a set of wrappers (31), (32), (33), (Fig. 7, not shown), and lays them on the block. As the latter is engaged by the conveyer D it is passed into a wrapper-folding member E. Each suction rod 25 is mounted on a rotary main plate 14 of the elevator and is connected to a vacuum manifold 26 (Fig. 3). Each pairs of grippers 3 of the elevator B are each pivotally mounted on the plate 14, and are in geared engagement. One of the grippers of the pair is controlled by a cam 22. Each pair of grippers is caused to rotate as the plate 14 rotates, by a gear train arrangement (Fig. 4, not shown), so that relative to the fixed machine frame, the grippers actually remain in fixed orientation. The lower gripper 34 is operated from a cam 48 (Fig. 8) via rods 44, 45, which pass concentrically within the drive shaft of the plate 14. The upper gripper 35 is carried by a vertically movable parallel linkage 50 from a longitudinally - slidable carriage 51. These two movements are also derived from the cam 48.

Abstract: 1356696 Centrifugal separator SULZER BROS Ltd 19 Nov 1971 [23 Dec 19701 53901/71 Heading B2P A centrifuge, e.g. for separating oil (or liquid fuel) and heavier impurities from cooling water for an i.c. engine, comprises a hollow rotor 14 forming a separating chamber 21 having an inlet for liquid to be cleaned and an exit aperture 28 for cleaned liquid, and a drive chamber 20 having a liquid outlet 27 arranged to produce a jet the reaction of which imparts a rotary force on the rotor,- there being no communication between the separating chamber and the drive chamber. Cooling water to be cleaned is introduced through ducts 25, 24 into the separating chamber 21 and, after being cleaned, passes out via exit apertures 28 (which preferably extend tangentially to act also as drive nozzles) into an annular discharge chamber 30 formed between the rotor 14 and a stationary housing 11, 12. A baffle plate 32 ensures that the cleaned water flows down along the inner wall of the housing. Oil or fuel removed from the cooling water discharges through a duct 33 to an exit duct 34 in the rotor spindle 13. Operating medium, in this case cooling water, is pumped through ducts 23, 22 into the drive chamber 20 which is separated from the separating chamber 21 by a partition 18 and from which the operating medium is discharged through outlets 27, which are in the form of tangential drive nozzles, into the chamber 30. Heavier particles contained in the cooling water are deposited on the wall of the rotor. The centrifuge 10 may form part of a cleaning installation for the cooling water of a marine diesel engine as shown in Fig. 2. Polluted cooling water is fed to a tank 41 through a pipe 43. A top layer having a high oil concentration forms in the tank 41 and cooling water to be cleaned is drawn from this layer through a suction line 52', 52 by means of a float 53 bearing an intake cup 54. Clean cooling water flows through a pipe 42 to another tank 40 from which it is fed to the engine by a pump 45 and a pipe 46. The pump 45 also delivers water via a pipe 47 to drive the centrifuge 10 and via a branch pipe 50 which contains an ejector 51 which draws the cooling water to be cleaned through the reaction line 52', 52 and feeds it to the centrifuge. The pipe 50 is provided with a spill valve 55 to control pressure in the line 52', 52. Separated oil is discharged from the centrifuge through a pipe 57 to a reservoir 58. The tanks 40, 41 have a common venting pipe 44.

Abstract: 1,199,429. Resistance welding systems. WELTRONIC CO. 7 Dec., 1967, No. 55688/67. Heading H2H. In a resistance welding circuit, means are provided for sensing the instant at which each half cycle of the load current passes through zero which means initiate through a further circuit providing a variable delay the connection of a load to a source. A circuit is also provided to allow the ignition firing pulses to a pair of ignitrons only when they are blocked. When the load current through ignitrons 1Ig, 2Ig ceases, the voltage across them increases which is detected by a transformer 4T causing a transistor 4Q to block, hence the potential on a conductor 122 rises and passes a current to a heat adjusting potentiometer P2 and a resistor P5 to charge a capacitor C27 which determines the firing delay. At a determined voltage, unijunction, transistor UJT3 fires rendering a thyristor SCR7 conductive which through a diode RE46 grounds the base of a transistor 3Q, blocking it. This allows a voltage, also from transformer 4T, through a diode RE39 and 4 layer diode RE52, to fire a thyristor SCR6 discharging a capacitor C24 through a transformer 3T creating a pulse to fire SCR2 to fire 2IG. Capacitor C24 is charged in the opposite half cycle. An identical circuit 102 is provided for igniting 1IG, also supplying a firing pulse only if both ignitrons are quiescent. The circuit may incorporate a known arrangement (not shown) whereby the first cycle has its firing pulses delayed with respect to the remainder (sec for example Specification 1,067,893). Thyristors SCR2 and (SCR1) (not shown) may be employed directly in the load current circuit.
