Title: Improvements in magnetic core devices
IPC: H01F3/08
Filed: 1956-08-24
Abstract: 841,426. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 24, 1956 [Aug. 25, 1955], No. 25994/56. Class 40 (9). [Also in Group XXXV] A magnetic core device suitable for performing logical functions comprises a magnetic core 5 in which a remanent flux may be set up in either direction and which is provided with an output winding 7 and two input windings 11 and 13 which link different parts of the magnetic circuit. As shown in Fig. 1, the two windings link the two branches provided by an aperture 9. Remanent flux is set up by pulsing both input windings, and if either winding is pulsed in the reverse direction there is no substantial output. If, however, both are pulsed in the reverse direction simultaneously the flux is reversed, providing a large output. The device thus behaves as an AND device. In Fig. 3, an OR device is disclosed having an input winding 15 to set the remanent flux, an output winding 15 and two sampling windings 21, 23 linking different parts of the core. The pulsing of either winding 21 or 23 affects the reluctance of the circuit and gives rise to an output pulse. Other embodiments where the sampling windings are differently arranged are also disclosed (Figs. 2 and 4, not shown).

IPC: D04H3/04
Filed: 1970-07-22
Abstract: 1324661 Laminates HERCULES Inc 22 July 1970 [22 July 1969 16 Dec 1969] 26379/70 Heading B5N [Also in Division D1] Two layers, each comprising substantially parallel synthetic thermoplastic filaments in spaced apart side-by-side relationship with adjacent filaments interconnected by a plurality of fibrils, are cross laid one upon the other with the filaments of one layer being disposed at an angle of from 20 degrees to 90 degrees to those of the other layer and the two layers being bonded together to form a net-like non-woven fabric. The filaments may be 1À5 to 20 denier polypropylene, polypropylene/ethylene copolymer, nylon, polyethylene terephthalate or polyacrylonitrile, they may be foamed or bicomponent (so as to crimp on heating) and are preferably produced by fibrillating plastics film, by passing the film over a triangular crosssection rotatable bar 6 having serrated edges 7, Fig. 2. In the embodiment of Fig. 4 the warp filaments are drawn from one or more supply beams 11 by pinch rolls 18 through annular former 12 on to stationary mandrel 13. Weft filaments 14 are laid on to the covered mandrel by the rotation of the carrier 16 of supply beams 15 at an angle of 20 to 89 degrees determined by the ratio of the speed of advance of the warp and weft filaments. The tubular fabric is compressed by pinch rolls 18 into a sandwich of inner warp filaments and outer weft filaments. The rolls 18 may be heated to cause bonding by fusion at the cross-over points, or the films fused by ultrasonic heating, or an emulsion, dispersion or solution of an adhesive sprayed on by nozzles 19 and cured by oven 20. In the embodiment of Fig. 6 (not shown) the method is modified in that (a) the warp films are drawn over an adhesive roll (30) placed before mandrel 13, which carries an inert, non-adherent coating, and (b) on leaving the mandrel the fabric tube is slit along one or both edges by a knife (31) placed ahead of pinch rolls 18, so that the warp filaments are overlaid by weft filaments on one side only. In the embodiment of Fig. 7 the warp filaments are drawn off supply beam 33 by pinch rolls 34 between a pair of continuous endless wire belts or cables 35, 351. The weft filaments are supplied by beams 36 which rotate around the warp and belts 35, 35<SP>1</SP>, and slit by knives adjacent to rolls 34 to remove them from the belts. Bonding is by heated pinch rolls 34 or by application of adhesive. In the embodiment of Fig. 8 (not shown) warp filaments (40) are fed from roll (41) by pinch rolls (42) on to a moving continuous belt (43) to calender rolls 44. Its advancement is periodically interrupted whilst a cross beam (45) is rolled across the warp at a 90 degree angle, a hot wire (46) severs the laid weft filaments, and the beam retracted.

Title: Mechanism or apparatus for selecting and feeding headless pins or like pointed or sharpened members as in the production of lags or staves for carding engines
IPC: B65G47/14
Filed: 1933-09-26
Abstract: 422,003. Nailing. BATEMAN, L. H., 1, The Mount, Halton, Leeds. Sept. 26, 1933, Nos. 26469 and 33950. [Class 89 (iii)] [See also Group II] Headless pins, such as those employed in wooden lags or staves for carding treatment of flax and like fibrous materials, are subjected to pressure or a sharp blow in their passage to driving position. If this is received on the pointed end, the pin is raised and thereby rendered capable of ready removal, while, if it is received on the barrel portion, the pin is retained in position to be fed forward in correct orientation for driving. In the apparatus shown, the pins are fed individually down an inclined glassfronted shoot e from bulk stock contained in a rotary hopper a having internal peripheral projections c. The pins are received in an upright position at the lower end of the shoot e on a deflector finger or arm g by which they are laid in succession by intermittent rotation of the finger g on the periphery of a revoluble barrel p which closes the bottom of the shoot. When flat on the barrel, they are struck by the pointed end of a pivoted arm s operated by a gapped cam v. If the pin is incorrectly oriented, its pointed end is struck and it jumps clear of the shoot into a hopper for transfer back to the hopper a. Otherwise, it drops into one of a number of gaps q in the periphery of the barrel p being assisted by a pivoted finger y. A stop 14 deflects the pins from the gaps q into the mouth of a vertical glass-fronted shoot r from the lower end of which the pins are transferred in succession, by a carrier slide 21, Figs. 1, 6, into the path of a driving tool 23 by which they are driven into the lag or stave 24. Should the shoot r be full, the die 14 has a wedging engagement with the bevelled side of one of the gaps q, and rotation of the barrel p, is arrested and the drum a, arm g and arm y are stopped also, a friction clutch plate 19, which permits slipping, being placed in the drive between the spindle 7, from which these mechanisms are actuated, and the main shaft 16. The tool 23 is driven forward by a spring 26 and is retracted by a cam 27 on the shaft 16. A one-way grip 28 for the rod 31 which carries the tool 23 permits it to move to the right, in Fig. 6, to drive a pin unless it is released by a pusher 29 actuated by a cam 30. A former 36 provided with contact devices 37 located in positions corresponding to those of the lag or stave in which pins are not required, and moved in unison with the lag, is employed to energize a solenoid 32 at those positions and thus to actuate the pusher 29 so as to free the grip 28. A friction coupling 44, Fig. 1, is provided between the slide 21 and its driving means to prevent damage to the machine if a pin becomes jammed.

Abstract: 725,263. Kinematograph apparatus. PAILLARD SOC. ANON. Sept. 28, 1953 [Dec. 6, 1952], No. 26578/53. Class 97 (1). A shutter has four separate interconnected blades, one of which is radially movable from an. operative position in which all four are equally spaced to an inoperative position in which the other three are equally spaced. The form shown has blades 1, 2, 3, 4 of which 1 is secured to the shaft 5 and 4 to a sleeve 16 and 3 is rotatable on the shaft 1. The blade 2 is guided for transverse movement on the blade 1 by pins and slots 9, 6 ; 10, 7 and has a slot 8 to accommodate the shaft. The blade 2 is connected to the blade 3 through pin 11 and slot 13 and to the blade 4 through pin 12 and slot 14, a slot 15 being provided in the blade 3 to permit their engagement. The pin and slot engagements are such that rotation of the blade 4, relatively to the blade 1, produces an equal and opposite rotation of the blade 3 and a radial movement of the blade 2. The blade 4 may be moved so that it and the blade 3 are opposite and the blade 2 moves outwardly opposite the blade 1 so that all four blades are effective and equally spaced. Alternatively the blades 3 and 4 may be moved into superposition to produce, effectively, a two-bladed shutter. The relative rotation of blades 1 and 4 is produced by an axially movable collar carrying a pin engaging a helical slot in the sleeve 15 and a longitudinal slot in the shaft 5.

Title: Improvements in gamma correction circuits
IPC: H04N5/202
Filed: 1968-06-04
Abstract: 1,205,164. Gamma correction circuit. COMPAGNIE FRANCAISE THOMSON HOUSTON-HOTCHKISS BRANDT. 4 June, 1968 [1 June, 1967; 20 Dec., 1967], No. 26592/68. Heading H4F. An adjustable gamma correction circuit for a television transmitter-receiver assembly comprises a transistor current-generator 1, a gamma correction transistor 2, a differential amplifier 3, a phase reversal transistor 4 and a variable-gain amplifier and combining circuit 5. The video signal to be corrected is fed from input terminal E through the current generator 1 to the gamma correction transistor which produces two outputs, one being a first signal altered according to a fixed law of the form: (output) = = (input)γ from the use of the transistor 21 as a semiconductor junction, γ being a constant = 0À4, and the second being simply an unaltered signal whose amplitude is equal to the first due to the use of the transistor 21 as a linear amplifier. The first, altered, signal is fed via the differential amplifier 3 together with the second, unaltered, signal and an output proportional to their difference is fed to the combining circuit, and the second, unaltered, signal is via the phase reversing transistor 4 to the combining circuit 5, whence an output signal is fed to terminal S of the form: (output) = A[(input)<SP>0À4</SP>- (input)] + (input), where A is the gain of the combining circuit. The D.C. component of the video signal fed to the current generator 1 is clamped by a level blocking or clamping voltage applied at terminal 11, and the output from the current generator is blocked for signals corresponding to black and open to other signal values. The gain A of combining circuit 5 is adjustable between 0 and 1 by potentiometer 53 which may be distant from the circuit. To eliminate background noise and parasitic signals the collector of the current generator transistor 12 may be connected to a source of negative pulses fed in concomitance with the line blanking periods. Further to reduce noise a low-pass filter of lower bandwidth than the television assembly may be connected in series with the first output from the gamma correction transistor, compensation in the second output being provided by a delay line. A source of constant amplitude negative pulses may be connected to either the emitter or the base of the gamma correction transistor by means of diodes in series opposition, Figs. 6 and 7, not shown, to cause a shift in amplitude of the characteristic curve of the semi-conductor junction and match it more closely to the correction curve desired.
