Title: Method of and apparatus for translating wireless and other telegraphic messages
IPC: H04L15/20
Filed: 1923-03-21
Abstract: 220,971. Creed & Co., Ltd., and Creed, F. G. March 21, 1923. Strip-perforating machines.-Wireless or other telegraphic messages recorded in the form of an irregular or broken line on a sheet or tape by photographic, mechanical, electrochemical, or like means are automatically reproduced in the form of printed characters by the following arrangement. Light is focused upon the tape a fed by rollers c and, after reflection by or transmission through plain portions a<1> of the record b along a line at the centre of the type, in the case of a broken-line record, or to one side of the tape in the case of the irregular line record shown, acts upon a lightsensitive device such as a selenium cell h arranged in an electric circuit with a divided battery g and a balancing resistance i. Potential differences or increased potentials produced between the points f<1>, f<2> of the circuit by the plain portions a<1> are amplified by one or more thermionic valves u, or by jet or selenium relays &c. and operate an unpolarized relay x, the contact y of which produces positive or negative impulses in a relay 4 or other circuit, in order and at intervals corresponding to the message. The impulses may control a tape-perforating telegraphic receiver 5 such as described in Specifications 5490/05, [Class 40, Electric telegraphs &c.], and 165,820, [Class 40 (iii), Telegraphs, Electric], the perforated tape 6 thus produced controlling printing-apparatus 7 such as described in Specifications 8990/07, 164,370, and 184,558, [Class 100 (iv), Typewriters &c.]. Alternatively, the current impulses may control printing- apparatus directly through electromagnetic means.

Title: Improvements in street bollards
IPC: E01F9/615
Filed: 1946-03-18
Abstract: 607,016. Road signs. PINCHIN, H. W. March 18, 1946, No. 8324. [Class 3(ii)] [Also in Group X] A street bollard is mounted on a ball and socket or other universal joint at its base and is retained in or returned to upright position by a counterweight. As shown, a bollard 10 is screwed to a ball 14 and contains a plug 15 to which a counterweight 29 is attached by a universal joint 23, 26 and flexible connection 28. To damp the movement of the bollard, the counterweight is formed as a piston and moves in a cylinder 30 containing liquid. The piston is provided with two ports 31, 32 of unequal size, the larger of which 31 has a valve 33 at its lower end, the arrangement being such that the damping action will be greater as the weight moves downward than as it moves upward. A rapid return of the bollard to its vertical position will thus be avoided. The bollard carries a flexible covering 21 for the ball 14, and at its free end mounts a reflector 12 and head 11, the wall of which has cut-out stencil letters, the interior being reflective. Light from a lamp unit 37 mounted on a socket plate 17 is directed into the head to illuminate the stencil.
Patent GB-523136-A (GB)
Title: Improvements in or relating to photographic shutters
IPC: G03B9/22
Filed: 1939-03-15
Abstract: 523,136. Photographic shutters. KODAK, Ltd. March 15, 1939, No. 8331. Convention date, March 16, 1938. [Class 98 (i)] The setting lever of a shutter sets a master member against the action of a power spring through a lost-motion connection which permits further movement of the lever after the master member has been latched by a trigger release. The effect of play in connecting members between the setting lever and film advancing means may be thereby eliminated. In the shutter shown, a master member 17 is rotated against the action of a spring 20 by a pin 25 operating in a radial slot in the power member and carried by the setting lever 7. At the end of the setting movement, in which the master member is latched by an arm 11 on the release trigger 5, the pin 25 rides on to the end face of a shoulder 24 on the master member, to the position shown, in which position lost motion may occur between the setting lever and the master member. In addition to being latched by the trigger arm 11, the master member is also latched by the engagement of the pin 25, with the end of the shoulder 24. The setting lever 7 is carried by an arcuate member 16 sliding in a similar slot 26 and having a lug 15 at its end which in the set position of the shutter engages an arm 12 of the trigger 5 so that when the trigger is operated it causes an initial movement of the member 16 and the setting lever which causes the pin 25 to unlatch the master member 17, and also reduces the inertia effect of the lever 7 and arcuate member 16 on the operation of the shutter.

Title: Improvements in or relating to apparatus for measuring the extension of ferro-magnetic material during the process of rolling
IPC: G01B7/04
Filed: 1947-03-27
Abstract: 627,000. Electric indicating systems. LOVE, A., SIK, G., and BALDWIN INSTRUMENT CO., Ltd. March 27, 1947, No. 8377. [Class 40 (i)] Apparatus for measuring the extension of ferro-magnetic material during a rolling process comprises means for magnetizing a strip of the roll both before and after the rollers by energizing coils 13, 17 fed from a common A.C. supply, and a pick-up coil 14, 18 associated with each magnetizing coil arranged to feed jointly into a phase discriminator 28, so that the difference in travelling speed of the material before and after compression can be determined from the phase difference in the pick-up coils. The pro-compression coils 13, 14 are in line in the direction of travel of the material, but displaced from the axis of the post-compression coils 17, 18, which are also in line in the direction of travel of the material. The distance between coils 17 and 18 is fixed, but the distance between coils 13 and 14 is variable by means of a calibrated drum attached to coil 13 by means of a lever 15 capable of moving coil 13 a small amount in the direction of travel. The distance between the coils of each pair is initially arranged to be such that the pick-up voltages are in phase when the extension of the material is the desired amount. The frequency of the A.C. energizing supply is tied to the speed of the rollers by driving the alternator and rollers from a common source.

Title: Improvements in and relating to cop winding mechanisms
Inventor: REINERS DR WILHELM
IPC: B65H54/14
Filed: 1937-03-22
Abstract: 486,474. Winding yarns. REISERS, W., (trading as SCHLAFHORST & CO., W.). March 22, 1937, No. 8393. Convention date, April 22, 1936. Addition to 474,738. [Classes 120 (ii) and 120 (iii)] The cop-winding machine described in the parent Specification is modified so that the spindles are donned with short starting tubes or cones upon which one end of the cops are wound, a swinging storage container or tube holder being provided for each spindle and holding a number of tubes or being provided with one tube at a time from a feed magazine or shoot; the swing- ing container is, during winding, disposed at the side of the spindle and during donning is rocked with the tube or tubes into alignment with the spindle and is then moved parallel thereto to don a tube and, after releasing the latter, is rocked away from the spindle and moved back to its original offset position from which it started. As shown the swinging container or tube holder 147 carries a number of short tubes 10, which can be released singly from the bottom by opening a spring-loaded catch, and is carried by a double-armed lever 62 rotatable on a rod 222 and having its lower end slotted to engage a horizontal rod 146 on a pivoted lever 63 actuated by a cam 66 on the shaft 39. The tube 10 on which the winding is started is initially placed on the winding spindle 4 and abuts against a counterhead 220 on an arm 221 fixed to a rack 225 gearing with a wheel 226 on a shaft 39 and when the winding is completed the arm 221 has moved to the right off the spindle 4 and contacts with a collar 223 on the rod 222 which carries a, doffing cone 219a encircling the spindle 4. The movement of the rod 222 causes the cone to push the completed cop off the spindle and the cam 66 then swings the holder 147 into line with the spindle, the counterhead 220 being retracted to push the holder to the left so that the lowest tube 10 therein is pushed on to the spindle 4 ; the holder 147 is then swung away from the spindle, the spring-loaded catch automatically opening to allow this, and, finally, is moved back to its original position at the side of the spindle 4. The formation of the cop is assisted by a cone 145 rotatable on an axle 144 in an arm 143 on a shaft 142 carrying a spring-loaded arm 141 engaged by a cam 140 on the shaft 39, the cam swinging the cone aside to allow the cop to be doffed on completion of the winding. The holder 147 may be detachably secured to the lever 62 and when arranged to carry single tube as shown by the dotted lines, the holder, after donning, is moved in front of a magazine or shoot 98 provided with a shutter which then. allows a single tube to slide into the holder.

Title: Improvement to the self acting mule as regards winding of threads on to the spindles, and taking in of the carriage towards the roller beam
IPC: D01H3/06
Filed: 1952-04-07
Abstract: 719,727. Spinning-mules; taking-in motions. BHIDE, C. S: April 7, 1952, No. 8797/52. Class 120(2) A spinning-mule in which the threads draw the carriage towards the roller beam as they are being wound on to the spindles has a catch device arranged to prevent downward movement of the counterfaller during winding by contact with a ratchet wheel keyed on the counterfaller shaft, the spindles being driven at a constant speed through the backing-off wheel, fast pulley and rim pulley. During the outward run, the carriage is driven by a pinion mounted in a bracket on the carriage and splined on a rotatable shaft extending in the direction of carriage movement parallel to a fixed rack with which the pinion engages. After backing-off has taken place in the usual way, the backing-off wheel is maintained in engagement with the fast pulley, but its direction of rotation is reversed by means controlled by the faller leg. As the faller leg rises at the end of the inward run, the counterfaller also rises and is locked by a spring-urged catch B in contact with the ratchet wheel A on the counterfaller shaft and is held until the end of the inward run when an elbow B<SP>1</SP> on the catch B makes contact with a fixed bracket V<SP>2</SP> and moves the catch B. At the same time, a bracket V<SP>1</SP> strikes the faller leg and causes it to descend. This movement of the faller leg disengages the backing-off wheel.
