Title: Improvements in copolymers and methods of making them
IPC: C08F214/24
Filed: 1944-05-15
Abstract: Trifluorochloroethylene and acrylonitrile are copolymerized in the presence of ultra-violet light or a peroxygen compound, e.g. benzoyl peroxide.  The process may be carried out in bulk, in a solvent such as acetone or in emulsion using as emulsifying agent a higher alcohol sulphate, an alkyl aryl sulphonate or a sulphonated long chain alkyl ester of an aliphatic carboxylic acid.  The product is infusible and insoluble.  In an example the monomers, together with a mixture of lead tetraethyl and benzoyl peroxide are introduced at -70 DEG  C. into a vessel transparent to ultra-violet light which is then sealed to maintain the monomers liquid at room temperature, and exposed to ultra-violet light. The copolymers may be used as fillers or abrasives in tooth powders and pastes or may be hydrolysed as described in Specification 351,508.

Abstract: 890,826. Printing-telegraph receiving apparatus. SIEMENS & HALSKE A.G. March 16, 1960 [March 16, 1959], No. 9277/60. Class 40(3). Perforating apparatus for signals comprising code combinations of elements in which a plurality of code combinations are applied in succession to the said apparatus to condition a corresponding number of sets of punches which are actuated simultaneously. The code combinations may be applied to storage means associated with the sets of punch members, and in one arrangement all the signals of a plurality except the final signal are passed to storage members, and the final signal is applied directly to an associated set of punch members. In the diagrammatic arrangement, Fig. 1, the five signal units of a first signal 1 are applied to a storage device Sp and with a very slight delay are passed to a first set St1 of punch members. During the movement of the tape between the punching -operations during the first half revolution of a control shaft, a switch member u is moved to its opposite position so that the second signal is passed directly to the second set St2 of punch members. Both sets of punch members are operated simultaneously during the second half-revolution of the control shaft, during which the switch member u is restored to the position shown. The two groups of perforations may be disposed laterally on a tape of double width, Fig. 3 (not shown), which may be advanced by two sprocket wheels engaging separate sets of feed perforations, Fig. 4 (not shown). In a modification, Figs. 5 and 7, the tape 27 with its plane vertical is fed between punch heads 21, 22 having its sets 25, 24 respectively of punch members staggered in the longitudinal direction of the tape. The pins 35 of the opposed sets 24, 25 are associated with die plates 31, 32 having opposite the pins, sets of holes 34 leading to enlarged portions 34a communicating with cut-out recesses 36, 37 for the passage of the punched-out paper discs or chads to a waste container.

Title: Photographic camera with built-in flashlight apparatus
IPC: G03B9/70
Filed: 1963-03-08
Abstract: 1,019,505. Photographic cameras with built-in flash light apparatus. AGFA A.G. March 8, 1963 [March 9, 1962], No. 9346/63. Heading G2A. A photographic camera with built-in flash light apparatus has attachment means for further flash light apparatus of different ignition time, variable ignition timing means and means for setting the timing means in accordance with the flash light apparatus to be used, the setting means being controllable for setting to at least one ignition timing position by bringing into working position a part of the corresponding apparatus. Insertion of a bulb 7 in spring contacts 4, 5 depresses pin 19, thereby moving spring contact 13 into position 13<SP>1</SP> nearer a contact lever 12. A bulb holder 10 is in parallel with the contacts 4, 5. The contact 13 is carried by an arm 20 of a speed regulating device for the shutter blades 42, 43 opened by lever 47. The lever 47 carries an accelerator arm 50 carrying contact lever 12. Lever 47 is rotated in the direction of arrow c to make an exposure, thus causing arm 50 to meet an abutment 52 and slide along it and tension spring 51. The spring 51 accelerates arm 50 when it disengages abutment 52 and rotates lever 38 to open shutter blades, thus giving an exposure time suitable for electronic flash. For an exposure using the built-in flash bulb 7, insertion of the bulb causes depression of pin 19 thereby rotating setting means 21 to position abutment 37 outside the path of lever 38 to produce a slower shutter speed. A manual setting lever 22 can also rotate setting means 21. In another embodiment a masking lever 71 Fig. 2 (not shown) covers a flash light socket 65. Displacement of lever 71 in the direction of arrow g to expose the socket 65 displaces an abutment in the direction of arrow f to lift contact 61 to interrupt the circuit to the built-in flash light apparatus. A control rod 75 connected to the lever 71 allows rotation of the setting means 21 by a spring 79, thus setting a faster shutter speed as described in relation to Fig. 1. In a further embodiment, the spring contact 13 Fig. 3 (not shown) is moved into a position suitable for synchronization of built-in flash light apparatus by a pin 80 urged upwardly by spring 83. The camera includes a further flash light apparatus with a reflector having sections 85, 86, such that by pivoting section 86 about hinge 87 in the direction i a member 89 depresses arm 81 and thus moves the pin 80 downwardly to adjust the position of spring contact 13 to vary the ignition timing.

Title: Improvements relating to hopper feeders for textile carding machines
IPC: D01G23/04
Filed: 1956-03-29
Abstract: 826,409. Hopper feeders. TAYLOR & SON Ltd., F. W., and TAYLOR, N. March 25, 1957 [March 29, 1956], No. 9844/56. Class 120(1) [Also in Groups XVIII and XXXVIII] In a weighing-type hopper feeder, each batch of weighed material from a weigh pan 1, before being deposited on the feeder sheet 6, is re-weighed in a second weigh pan 2 to detect inaccuracy in the first weighing, and the speed of the machine is adjusted in accordance with the result of the second weighing after a delay such that any correction becomes effective when the batch in question reaches the licker-in rollers of a carding machine being fed. During filling, pan 2 is supported on arms 4; when the pan is full, arms 4 are moved by a cam 5 to lower the pan on to a weigh beam 3 fitted with a centre-zero type spring balance 9. A counterweight 13 is adjusted on beam 3 so that with a given weight of fibre in pan 2 the beam takes up a zero position indicated by a pointer 12. After weighing is effected, arms 4 lift pan 2 off beam 3 so that abutments 8 engage catches on the pan causing it to open and discharge the fibre on to a feeder sheet 6; as the pan rises further it is caused to close ready to receive the next weighing from pan 1. If a batch of fibre delivered to pan 2 is not of the correct weight, there is a proportionate displacement of beam 3 from the zero position during the weighing operation. This displacement is used to effect a corresponding change in speed of feeder sheet 6, licker-in rollers 7, cam 5 and the lattice sheet which feeds weigh pan 1, the control becoming effective once in each cycle; the control may be carried out by means of a variable condenser controlling a valve for varying the shunt current of a driving motor or by means of a vane with a series of holes and a photo-cell giving impulses to a rheostat in the shunt field; the change in speed is delayed until the batch in question is about to be delivered by rollers 7, for example by using a magnetic tape which stores the electrical impulses affecting the control. Balance 9 is adjusted in position on a graduated scale 11 according to the desired weight of the batches, so that a given deflection of beam 3 will always be obtained for a given percentage inaccuracy in the weight of a batch.
