Title: Improvements in or relating to methods of forming annular blanks
IPC: B21K1/04
Filed: 1961-12-19
Abstract: 934,514. Forging; punching; making roller bearing races. SVENSKA KULLAGERFABRIKEN A.B. Dec. 19, 1961 [Dec. 20, 1960; Dec. 21, 1960], No. 45402/61. Classes 83 (2) and 83 (4). An annular blank is formed by piercing a heated substantially cylindrical solid workpiece 21a from opposite ends successively, using substantially fully conical tools 24, 210. The workpiece 21a is formed by upsetting a solid cylindrical workpiece, Fig. 4 (not shown); simultaneously a locating spigot 25 is provided. During the first piercing step by punch 24, Fig. 6, the spigot seats in a recess 26 in a bed 29. The workpiece is then reversed, the conical recess located over a spring-loaded finger 27, Fig. 7, and punch 210 then pierces from the opposite end and punches out a small wad 212, Fig. 8. The spigot 25 is also pressed out. For making the inner and outer races of roller bearings, Fig. 9, an inner blank 2 which subsequently forms the inner race, is punched out of an outer workpiece 3 which forms the outer race. Simultaneously the blank 2 is pierced from one end by punch nose 5; it is then reversed and pierced from the opposite end, Fig. 11 (not shown), and then again reversed and further pierced from the first end, Fig. 12 (not shown). Finally the blank is rolled in a ring rolling mill. The punches may be wholly conical or have a rounded nose or a short cylindrical or reverselyconed nose, Figs. 13-15 (not shown). They are made of hard metal with sufficient porosity to permit lubricant from an interior reservoir to seep to the outside.

Filed: 1975-11-04
Abstract: 1512675 Testing radar apparatus TELEFONAKTIEBOLAGET L M ERICSSON 4 Nov 1975 [6 Nov 1974] 45830/75 Heading H4D A radar receiver is tested for tracking accuracy by simulating a fixed target in a known direction, by using a radiant energy beam (other than the operational radar beam) deflected in dependence on movement of the radar antenna to provide simulation signals. In the Fig. 4 system the radiant energy beam is a light or infrared beam emitted by source LE on the movable part MP of a monopulse-type radar antenna. This beam is received by a four-quadrant silicon photo-cell LR on the antenna's fixed part SP. Signals from the quadrants are combined at SE to give signals #, #S, #H representing respectively the sum of all four quadrant signals, deviation of the antenna from a reference azimuth direction, and deviation from a reference elevation direction. The signals #, #S, #H control electronic attenuators Dl, D2, D3 (detailed in Figs. 5 and 6, not shown) for modulating a pulsed signal at RF or IF frequency from source IG, the modulated signals being fed into the normal IF stages MF1-MF3 of radar receiver RM, in parallel with the normal monopulse signals. Stages MF1, MF2, MF3 feed echo display unit IND and servos TS, ES for steering the antenna in azimuth and elevation, respectively. In modifications LE and LR could be transposed, or both could be positioned on one antenna part to co-operate with a mirror on the other part.

Title: Methods and apparatus for producing stretch and bulked yarn
IPC: D02G1/10
Filed: 1961-12-22
Abstract: 1,012,968. Finishing yarns. DEERING MILLIKEN RESEARCH CORPORATION. Dec. 22, 1961 [Jan. 9, 1961], No. 46065/61. Headings D1F and D1W. In a method of treating yarn to impart stretch/ bulk properties, (a) latent crimp is intermittently introduced into a multifilament, continuous filament thermoplastic yarn as it is linearly progressed and (b) such crimp is subsequently developed e.g. by continuously overfeeding the yarn, the steps (a) and (b) constituting a single continuous process. The latent crimp may alternate with zero latent crimp or with a lesser degree of latent crimp in which latter case a crimping apparatus may comprise two different yarn engaging members selectively engageable with the yarn to impart different degrees of crimp thereto. In the apparatus shown, yarn Y is fed from a supply bobbin 11, through guides 13, over a larger diameter portion 14a of a feed roll assembly 14, to a crimper 15 wherein yarn passes in one or more wraps around portion 17a of a rotatably driven grooved heater roll 17, over the edge 21a of a blade 21 and then over a driven roll 23, whereby it acquires some patent crimp and a larger latent crimp. As the yarn passes through the crimper, it is periodically moved at regular or random intervals into and out of contact with the edge 21a by an arm 29 connected to the reciprocable armature 31a of a solenoid 31 which is actuated by an intermittent electrical signal generator 33. The latent crimp is developed by return passage of the yarn around a smaller diameter portion 14b of assembly 14 and then around portion 17b of roll 17, before the treated yarn is fed to take-up mechanism 27. Specification 909,362 is referred to.

Filed: 1969-09-23
Abstract: 1,249,700. Controlling aircraft. BENDIX CORP. 23 Sept., 1969 [1 Oct., 1968], No. 46811/69. Heading B7G. [Also in Division G1] A redundant control system for an aircraft provides three identical signal channels which actuate a controlled device 25 in response to movements of a control stick 26. Each channel has a sensing system 1, 1A, 1B, each of which provides a first selected output corresponding to the actual pitch rate sensed by gyro 30 and a second selected output corresponding to the expected pitch rate. Samplers 40, 42 sample the sensed and expected rates respectively and the difference is applied to a digital counter 70. A comparator 49 receives the expected response sample and the difference and determines if synchronization of the control signals in the three channels is necessary. If so, signals from the source 43 are utilized to set the counter 70 to synchronism with the counters in the other channels. In the event that three consecutive synchronizing sequences do not produce synchronism the counter 98 is set to actuate an alarm 100. During synchronization, the output from the counter 70 is applied to a variable gain device 117 so that the signal from the control stick sensor 123 to the input of the rotor 123 is brought to the value selected by the rotor 123, each of which is connected to all the channels. The value selected is the intermediate value of the three. This intermediate value is then fed to the controlled device 25 which in use is an hydraulic actuator for the elevators. The channels are so interconnected as to provide 27 possible signal paths.

Abstract: 1278819 Diaphragm setting device NIPPON KOGAKU K K 24 Sept 1969 [24 Sept 1968] 46998/69 Heading G2A A diaphragm comprises a number of blades 3 which are operated by two rings 1, 2 which rotate simultaneously in opposite directions. As shown, toothed portions 4a and 5d on gear rings 4 and 5 are both engaged by a pinion 6a rotated by a knob 6. Thus as knob 6 is turned, rings 4 and 5 rotate in opposite directions. The rings are linked respectively with rings 1 and 2, so that these also rotate simultaneously in opposite directions. The diaphragm blades 3, of which only one is shown, each have a pin 3a which engages in a hole 2b in ring 2, so that the blade can pivot about this pin. The blade has a cam slot 3b, in which engages a pin 1b on ring 1. Thus as the rings 1 and 2 rotate, the blades move from the "fully open" position of Fig.2 towards the "closed" position, as in Fig.3 (not shown). A scale 4b on ring 4 reads against a pointer 7. In the modification of Fig.5 (not shown) the linkage to ring 2 has a slightly different form.

Abstract: 1369802 Magnetic sheet recorder RICOH KK 13 Oct 1971 [5 Nov 1970] 47601/71 Heading G5R A magnetic recorder of the type in which a read/record head is moved in a spiral path over a stationary magnetizable record sheet, the head being mounted for radial movement on a turntable so as, to move in the desired spiral path, is characterized in that the turntable control mechanism is such that a first depression of a control key sets the table rotating and a second depression of the same key stops the table rotating. As described, depression of a control key 9, Figs. 15, 17, slides a member 86 forwards. The forward end of member 86 impinges upon an upwardly-bent portion 113a, extending through a hole 196 in the base-plate 19, of a lever 113, Fig. 16, mounted below the base-plate. As a consequence of depressing the key 9, firstly the lever 113 is moved to its position shown by dotted lines, in which position a switch 123 is actuated to turn on the motor, and two shafts 104, 108 are displaced so as to move two rim-drive wheels 103, 107, Fig. 15, into contact with a driven capstan 124, secondly the upwardly-bent portion 113a, Fig. 18, of the lever 113 rocks two brake levers 92, 93 to remove two brake shoes 93, 102 from the turntable rim, and thirdly the upwardly-bent portion 113a is latched in its displaced position by a projection 89a on a spring loaded lever 89. Thus, once the upwardly-bent portion 113a is latched by the lever 89, the key 9 can be released, being restored to its normal position by a spring 85, Fig. 17, and the turntable will continue to be driven. However, when the member 86 is retracted by the key 9, a portion 89b, Fig. 16, downwardly-bent through a hole 19a in the base-plate 19, now bears on a portion 113d of the deflected lever 113, so that the member 86 assumes an inclined position shown in full lines in Fig. 19. The result is that when key 9 is next depressed, rather than the member 86 moving straight forward to strike the projection 113a as before, because of the inclined position of the member 86, and the friction between it and the base-plate 19, the end of the member 86 misses the projection 113a, and hits a pin 89b on the locking lever 89 instead. The lever 113 is therefore unlatched, the turntable drive is removed, and the brakes are applied, and when the key 9 is released, the member 86 is retracted and twisted into its normal position by a spring strip 128, Fig. 19. The apparatus described also includes head drive means and means for retracting the head from the record when reading or recording is not taking place, all of which is described and claimed in Specification 1,369,801.
