Filed: 1963-08-20
Abstract: Photopolymerizable compositions comprise, by weight (a) 10-60 parts of an addition polymerizable, non-gaseous, ethylenically unsaturated compound containing at least one terminal ethylenic group, having a boiling point above 100 DEG  C. at normal atmospheric pressure and capable of forming a high polymer by free-radical initiated addition polymerization;  (b) 40-90 parts of cellulose acetate hydrogen succinate having a degree of acetyl substitution of 1.5 to 2.45 and of hydrogen succinate substitution of 0.4 to 1.0, as bending agent; (c) 0.1 to 10.0 parts of maleic, glutaric, glycollic, lactic or citric acid, or a mixture of two or more such acids.  The polymerizable compound (a) may be e.g. a polyethylene glycol diacrylate prepared from a diol precursor of molecular weight 300-600.  The composition may also contain a free-radical generating, light activated initiator, e.g. 2-ethylanthraquinone and those disclosed in Specification 843,238, and also a polymerization inhibitor, e.g. p-methoxyphenol, hydroquinone, aryl- and alkyl-substituted hydroquinones, t-butyl catechol, pyrogallol, copper resinate, naphthylamines, b -naphthol, cuprous chloride, 2,6 - di - t - butyl - p - cresol, phenotriazine, pyridine, nitrobenzene, dinitrobenzene, p-toluquinone, and chloranil.  The compositions may be made by merely mixing the constituents. Alternatively, the cellulose ester may be formed in situ by a melt esterification using a catalyst such as diethyl cyclohexylamine, pyridine, triethylamine, tributylamine, triamylamine, trimethylamine acetate, pyridine acetate, sodium or potassium carbonate, sodium phosphate, acetate, and borate, or lithium, calcium, potassium or magnesium acetates. The catalyst may comprise up to 20% of the composition.  In an example, a mixture of pulverized cellulose acetate (D.S. 1.85), polyethylene glycol diacrylate, succinic anhydride, p-methoxyphenol and 2-ethylanthraquinone is milled at 135 DEG  C.  After addition of diethyl cyclohexylamine catalyst and further milling to form cellulose acetate succinate, glutaric acid is added to complete the photopolymerizable composition.  The compositions are formed into sheets by calendering which are then laminated on to supports, with or without an adhesive, to form photopolymer printing plates (see Divisions B5 and G2).  Specifications 741,294, 741,441, 741,470, 807,948, 825,795, 834,337, 850,453, 854,980, 864,041, 883,558, 905,070, 935,627 and 945,807 also are referred to.

Abstract: 848,441. Condenser arrangements. C.A.V. Ltd. Nov. 2, 1956 [Nov. 22, 1955], No. 33375/55. Class 38 (4). Apparatus for electrifying an electric fence comprises an electromagnet having a pair of oppositely-wound operating coils a, b and contacts d which are normally closed, the coil a having a larger inductance than the coil b which latter coil b is serially connected to a condenser c. When a source of direct current is applied to the parallely connected coils a, b the condenser c charges up by way of the coil b. During this period the predominating effect of the coil b will maintain contacts d closed and the change of voltage across the coil b as the condenser charges will cause energization of a fence connected to the secondary winding e1 of a transformer connected across the coil b. When the condenser c is fully charged, the coil a predominates to open contacts d whereupon the condenser o discharges through the coils a, b, causing a further energization of the fence. When the condenser is discharged,-contacts d reclose and the cycle is repeated.

Title: Improvements in or relating to photographic cameras
IPC: G03B7/00
Filed: 1956-11-02
Abstract: 848,878. Photographic cameras. GAUTHIER G.m.b.H., A. Nov. 2, 1956 [March 13, 1956], No. 33562/56. Class 98(1) In a photographic camera having a shutter and an interchangeable lens mount, the diaphragm setting mechanism of which is releasably coupled through a transmission ring to the shutter speed setting ring when the lens mount is attached to the shutter, the diaphragm mechanism is urged by a spring to its closed or fully open position and has a coupling member which is moved by this spring into contact with an abutment connected to or provided by the transmission ring when the lens mount is fitted on the shutter. As shown, the camera is substantially as described in Specification 848,451 modified in that the ring 19 has a lug 19c, for engagement with a coupling pin 41 connected to the diaphragm setting mechanism and projecting through a slot 7b in the mounting plate 7. Engagement of pin 41 and lug 19c is maintained by a spring (not shown) which tends to move the diaphragm blades into the closed position. When the lens mount is detached, the spring moves the coupling pin 41 to one end of the slot 7b and thus closes the diaphragm blades. Before fitting a new lens mount, the diaphragm setting mechanism is moved as by setting ring 8 against the action of the spring so that pin 41 is at the other end of slot 7b and the blades are open. During this movement of the pin, it pushes a slide 45 to align a hole 45b therein with a bore in the mounted plate 7 so that a pin 44 (not shown) on the shutter plate can enter the bore, and also rocks a lever 42 which immediately returns under the action of a spring 47 to lock the pin 41 in its new position. The lens mount can now be fitted to the shutter by engaging pin 44 with the bore in plate 7 and during this operation the bevelled end of pin 44 rocks the lever 42 to release the pin 41 which is thereupon moved by the diaphragm spring into contact with the lug 19c. Specification 769,070 also is referred to.

Abstract: 1,101,962. Road traffic signals on vehicles, MAGNATEX Ltd. 26 Nov., 1964 [26 Aug. 1963], No. 33687/63. Heading G4Q. The coil 7 of a flasher unit of a turn indicating system is connected in series with an excess current relay C so that when the load is increased, e.g. by the addition of trailer lamps LT and RT to the circuit, the relay is operated to short-circuit part of the coil and prevent variation of the flashing rate. The relay C also connects an indicator lamp P2 in the circuit; failure of one of the three lamps will result in P2 not being illuminated as the relay will not operate. The invention is also applicable to maintain the flash rate constant in systems wherein the brightness of the lamps may be varied for day and night use. In a modification, Fig. 2 (not shown), the flasher is of the type described in Specification 936,274. In a further modification. Fig. 3 (not shown), the relay C is normally disconnected, but, on insertion of the trailer plug 31 into socket 32, is connected across the switch S so that it is energized through the lamps on the disengaged side.

Abstract: 1,076,223. Transistor circuits. HITACHI Ltd. Aug. 18, 1964 [Sept. 10, 1963], No. 33744/64. Heading H3T. [Also in Divisions G3 and H2] In a brushless D.C. motor the rotor position is indicated by a high-frequency signal appearing at one pair of stationary coils L6, L7, L8, say L8, and this signal e 3  is applied to NPN transistor TR 8  after rectification by diode D 3  as a substantially triangular wave. In addition, a bis voltage eb derived from winding L3 on transformer T 1  and rectified by diode D3 is added to the signal e 3  to alter the voltage applied to transistor TR 8  and hence its conduction time. The output of the NPN transistors controls the directly coupled PNP switching transistors TR 3 , TR 4 ; TR 6 , TR 7 ; TR 9 , TR 10  which control the supply of current to the armature windings L9, L10, L11. Since the duration of these current pulses is varied by varying the bias voltage eb the variable resistor VR 1  can be used to control the motor speed. In a modification the motor speed is stabilized by an additional circuit which sums the number of current pulses at the output of the NPN transistor in a given time and modifies the bias with this output which is proportional to speed. Reference has been directed by the Comptroller to Specification 1,032,066.
