Abstract: 1,060,616. Transistor bi-stable circuits. STANDARD TELEPHONES & CABLES Ltd. Nov. 8, 1963 [Nov. 15, 1962], No. 43278/62. Heading H3T. [Also in Divisions G1 and H1] An electrical test instrument, suitable for making continuity tests, includes a trigger circuit containing PNP transistor 1 and NPN transistor 13 whose stable operating state is determined by the magnitude of the load connected across the input terminals 7, 8. If a low resistance (less than 5 ohms) is connected between the terminals 7 and 8, the current through the transistor 1 increases so that the transistor 13 is switched on. The negative-going voltage produced at the collector of the transistor 13 is fed to the base of the transistor 1, and the opposite stable state to that occurring under no load conditions is established. The negative signal also switches on the transistor 15 and hence the lamp 19, thus indicating the low resistance condition at the terminals 7, 8. The particular resistance value at which the circuit triggers is adjustable by the potentiometer 9, and the circuit is temperature stabilized by the resistance chain 9, 10, 11, 12 (12 having a specified temperature characteristic) and the forward biased diode 21. The circuit and its batteries 4, 5 are contained in a torch-like holder, and the leads 7, 8, 24, 25 extend to a probe unit which contains the lamp 19. Details of those assemblies are given (see Division H1).

Abstract: 1,210,738. Rolling. MANNESMANNMEER A.G. 13 Sept., 1968 [13 Sept., 1967], No. 43555/68. Heading B3M. Roll changing arrangement, suitable for a tube rolling mill, includes rolls 14 each of which is supported by a bush 6 on a central axle, 1 the axle being axially withdrawable to permit removal of the roll vertically. The bush is formed at its right hand end with radial projections which engage in corresponding recesses in a driving sleeve 5.  To remove the upper roll, a bolt 3, which passes through the axle 1 to fasten the axle to the driving sleeve 5, is loosened. This loosening of the bolt first causes the roll and bush 6 to move to the right, until an extension 26 of the sleeve abuts the adjacent roll bearing 37, and then withdraws the bolt. The axle can then be removed, leaving the roll and bush supported, at the left hand side, on a projection 25<SP>1</SP> of the roll bearing 37, and on the right hand side, on the lower extension 26. The roll is free to be lifted vertically from the mill. The projection 25<SP>1</SP> can be pivoted out of the path of the lower roll to permit removal of the lower roll in a similar manner.

Abstract: 1,078,137. Fluid-pressure servomotor systems. POWER JACKS Ltd. Jan.27, 1966 [Oct.27, 1964], No.43782/64. Heading G3P. [Also in Divisions F1 and F2] A plurality of hydraulic rams 50, 51, 52 are individually controlled by associated spring- biased closed centred spool valves 53, 54, 55 supplied by a pump 64 delivering through a single line 62 having a by-pass line 65 provided with a shut-off valve 20 which is automatically closed when the piston (4) Fig.1 (not shown) of one or more master cylinders 1, 2, 3 is displaced in either axial direction within its cylinder to supply low pressure fluid through lines 57, 59, 61 or lines 56, 58, 60 to the ends of the control valve cylinders to displace the spools therein and which thus act as slave cylinders. Each master cylinder piston (4) is formed with opposed skirt portions (30, 31) having ports (28, 29) which in the spring centred neutral position connect both ends of each cylinder through medial ports (27), a common line 32 and open valve 20 to a pump supply reservoir 63. To bleed aerated fluid from a low pressure control line e.g. line 56 the latter is disconnected from the lower end of control valve 53, piston (4) of master cylinder 1 is displaced to the right and back pressure in the return line of the high pressure circuit and in by-pass 65 to which it is connected expels said aerated fluid. Each control valve 53, 54, 55 has a valve-controlled by-pass 83, (82) Fig.3 (not shown) for relieving pressure set up in the contracting side of the ram by its inertia after supply pressure has been cut-off by the valve spool being moved towards its central closed position. The sorelieved pressure acts on the end of the spool and prevents its complete closure until such time as pressure has been relieved to the return line 71 - 73 and reservoir 63. In a modification a ram (105) Fig. 5 (not shown) is cushioned near the end of its stroke by abutment of the ram rod (106) against the rod (107) of a spring-biased piston (102) within a buffer cylinder (100) and the resulting increase in cylinder space (101) which is connected by a line (108) to the upper end of the control valve slave cylinder serves to relieve pressure acting against the end of the spool which is then automatically closed by its centring spring.

A method for separating composite articles, such as cigarettes and filter cigarettes consisting of a wrapper and a filler, into component parts comprises subjecting the article to a compression action and thereafter tearing or slitting and opening out the wrapper. Cigarette groups G comprising two cigarettes Z and an interposed double length filter plug F are fed along a conveyer 1 towards two tearing and compressing wheels 2, 3 having toothed edges 4, 5 which interengage at the tearing point A. One of the wheels may be driven from the means driving the conveyer 1 and at a peripheral speed equal to the cigarette speed. The wheels 2 and 3 compress the groups as shown in Fig 2, perforate the paper, and subsequent divergence of the teeth 4 and 5 opens the cigarette paper P. The filter portions F are strong enough to withstand the action of the wheels. In a second embodiment (Fig. 3) the wheels 10 and 11 may be flexible in character. The cigarette groups are fed from a hopper 29 (Fig. 6a) on to a conveyer 26 and fall through a separator box 24 to the inside of a cup-shaped rotary wheel 19 around which the cigarette group conveyer belt 18 runs. The groups are forced against the belt 18 by centrifugal action and a series of guides guides the group between the wheels 2 and 3, the belt 18 being turned through 90 degrees before passing beneath the wheels 2 and 3. The belt is turned through a further 90 degrees after passing the wheels 2 and 3 and returns around a guide roller 20. The slit cigarette groups are impelled aaginst a plate 35 (Fig. 6b) and fall on to a vibratory screen 36. They then pass through a beater device 37 and on to a further vibratory screen 42. Usable tobacco falls into a container 49. Light particles sucked up the pipe 25 when the cigarette groups are fed into the separator box 24 fall from the duct 43 on to the residual material, filters and paper, on the screen 42.
