Title: Improvements in or relating to writing instruments
IPC: G09F23/00
Filed: 1960-11-17
Abstract: 938,485. Writing instruments. F. T. JOHMANN. Nov. 17, 1960 [Dec. 14, 1959], No. 39558/60. Class 146 (3). A writing instrument has a retractable writing point at each end, and depression of one or either of the ends against a rigid surface causes simultaneous projection or retraction of the points. As shown in Fig. 1 the twopart barrel 10, 10<SP>1</SP> has a sleeve 21 slidably mounted therein. One end 22 of the sleeve is closed and carries a tubular nipple 23 in which the rear end of a ball-point writing unit 15<SP>1</SP> is frictionally engaged. Two annular latch members 24, 25 are frictionally fitted in the sleeve 21, the member 25 having teeth 28 and the member 24 having pairs of teeth 27 separated from each other by deep recesses 26. The teeth 28 are circumferentially offset from the teeth 27. A cylindrical member 29 is slidable in the bores of the latch members 24, 25 and carries in an annular recess a laterally projecting ball 32. A second ball-point writing-unit 15 is frictionally engaged in a blind bore at one end of the member 29. The unit comprising the member 29 and writing- unit 15 is biased away from the unit comprising the sleeve 21 and latch members 24, 25 by a spring 34, but the units are held together by the ball 32 which engages either in a deep recess 26 of the latch member 24 (as shown) or in a shallow recess between the teeth 27. The outer ends of the writing units 15, 15<SP>1</SP> are telescopically arranged in hoods 14, 14<SP>1</SP> respectively, which are themselves slidable in the open ends of the barrel portions 10, 10<SP>1</SP> and which are biased towards positions in which they enclose the ball points 18, 18<SP>1</SP> by springs 36, 36<SP>1</SP>. As shown, both ball points are exposed for writing; pressing of either ball point on a rigid surface causes the ball 32 to move out of the recess 26 and into engagement with the inclined edge of a tooth 28 which causes the ball to rotate slightly in relation to the latch member 24. When pressure is released the spring 34 brings the ball 32 into engagement with a shallow recess between two teeth 27 so that the combined length of the parts 15<SP>1</SP>, 21, 29, 15 is shortened, and a new balance of the opposing springs 36, 36<SP>1</SP> is established so that the sleeve 21 moves a short distance longitudinally in the barrel and both ball-points are enclosed by the hoods 14, 14<SP>1</SP>. A further depression and release of either ballpoint causes the ball 32 to return to the recess 26 and both ball points are thereby returned to the projected position. Specification 876,206 is referred to.

Title: Data processing system
IPC: G06F9/448
Filed: 1974-09-12
Abstract: 1444306 Data processing system INTERNATIONAL STANDARD ELECTRIC CORP 12 Sept 1974 [19 Sept 1973] 39791/74 Heading G4A In a data processing system in which each main routine is performed by executing a respective sequence of sub-routines, each available sub-routine is executed by a respective basic circuit GE1-GE5, the basic circuits being wired together via an interconnection network VS and control circuit SS such that, in response to a signal Sm requesting a main routine, the appropriate basic circuits are energized in the appropriate sequence. Initially a main routine request Sm to control circuit SS sets flip-flop FF1 which, via line 5 and interconnection network VS energizes basic circuit GE1 at input 11 and enables AND gates at the inputs 21 and 41 to basic circuits GE2 and GE4. Basic circuit GE1 executes a sub-routine of instructions received over inputs 12 and on completing the sub-routine energizes output 14 which, via the enabled input 21, energizes basic circuit GE2. The sequence continues until the last basic circuit in the sequence, viz GE4, energizes output 44 which, via AND U2, gives a routine complete signal E. If following the completion of routine GE2, an alternative main routine is required output 23 is energized to reset FF1 and, via AND U1, set FF2. Flip-flop FF2 initiates a sequence of sub-routines in a similar way ending with a signal on line 54 to produce the routine complete signal E. The signal E may be connected to a further main routine request input which initiates a further sequence. A modified control circuit is described, Figs. 4 and 5 (not shown) in which respective routine request inputs (S1-Sm) set respective flip-flops (FF11-FF1m) whose outputs via a NAND gate set flip-flop FF1. The output of FF1 is gated by the outputs of flip-flops (FF11- FF1m) to m outputs 5, the energized one of which selects a main routine. The output from the last basic circuit in the sequence indicating completion of the sequence or the alternative routine select output from a basic circuit are gated by the m outputs 5 to set one of a set of flip-flops (FF21-FF3m) which set a flip-flop (FF2) and a new routine select signal is developed. The process repeats through n levels until n main routines have been performed. The system may be used to control a telephone exchange.

Title: Methods of optically aligning two objects
IPC: G03F9/00
Filed: 1974-09-19
Abstract: 1481099 Aligning objects photo-electrically INTERNATIONAL BUSINESS MACHINES CORP 19 Sept 1974 [11 Oct 1973] 40804/74 Heading G1A An object having an alignment pattern in relief to enable it to be photo-electrically aligned with another object is coated with a reflective layer to make the pattern more easily detected. In Fig. 1 a system is shown for aligning a semi-conductor wafer 11 with a mask 13. The system is described in detail in Specification 1414658. The wafer 11  has a relief alignment pattern in it, and it is found that due to multiple reflections in oxide and resist layers on the wafer the pattern can be obscured. For this reason the wafer is covered with a reflective layer which reflects light at an alignment wavelength but transmits at a wavelength which can expose the photo-resist layers beneath it. Suitable coatings are dyes such as Rhodamine B, Erythrosin, Wasser Blau or Sudan II, or metals such as aluminium, gold or silver, usable wavelengths being given in the description. The coatings are not wholly reflective at the alignment wavelengths, but are sufficiently absorbing to prevent any significant amount of light being passed through the coating, reflected off a lower layer and being transmitted back through the coating.

Title: Fluid-entrained material conveying systems
IPC: B65G47/00
Filed: 1962-11-02
Abstract: 969,995. Pneumatic conveyers. BAKER PERKINS Ltd. Nov. 2, 1962 [Nov. 2, 1961], No. 41500/62. Heading B8A. [Also in Division G1] In a pneumatic conveyer system in which particulate material is circulated through a ring main 10, 13, Fig. 4, and delivered in predetermined amounts to weighing hoppers 5 through diverting valves 14 which are automatically closed when the predetermined amount has been delivered, additional control means operates to close the valves 14 in successive stages so that the rate of delivery is reduced for more accurate measurement of the final quantity. In the example, the material passes directly through the valve 14 when the butterfly plate 18 is in the closed position B so that no material is delivered to the hopper 5. With the plate 18 in the fully open position A the material is deflected downwards into the hopper as at b, the air passing under the plate 18 as at c to continue circulation through the pipe 13. In an intermediate position D the plate 18 deflects only a proportion of the material into the hopper 5 to thereby reduce the rate of filling. The valve plate 18 is actuated through a crank 20 by a pair of hydraulic piston and cylinder assemblies 23, 25, the cylinder 23 on one assembly being rigidly connected to the pistonrod 24 of the other assembly. In operation, a first weight reading of the hopper scales operates solenoid controls, Fig. 6 (not shown), to actuate the piston and cylinder assembly 23 only so that the flap 18 is partially closed to the position D. At the final weight reading the piston and cylinder assembly 25 is actuated to bring the flap 18 to the fully-closed position. In a modification, Fig. 7 (not shown), the flap 18 is actuated by a single piston and cylinder assembly having a trip switch incorporated to cut off the pneumatic supply when the flap 18 reaches its partially closed position, the supply being re-connected when the hopper reaches the predetermined weight, and thereby fully closing the valve.

Abstract: 1,101,137. Woodworking. NATIONAL RESEARCH DEVELOPMENT CORPORATION. 20 Dec., 1965 [13 Oct., 1964], No. 41813/64. Heading B5L. A process for rendering timber more flexible comprises initially steaming the timber, compressing the steamed timber along a direction substantially parallel with the grain, releasing the timber and allowing it to equilibrate with the combination of temperature and relative humidity at which it is to be used, and then, for a second time, compressing and releasing the timber. In each case, the release may follow immediately or for a dwell time ranging from a few seconds to an hour, after the compression. In the first compression, the timber, such as steamed beech, is subjected to a compressive stress of the order of 3000 lbs/sq. in. and is compressed by 20% to 25%. In the second compression, the timber is cold and dry and the compressive stress is of the order of 9000 lbs/sq. in. Timber so treated is stated to be capable of being bent cold with an improved radius of curvature before failure occurs. The apparatus for compressing the timber may be as described in Specification 1,087,141.
