Title: Toy pistol with tiltable amorce strip carrier
IPC: F41C3/08
Filed: 1931-05-04
Abstract: 368,134. Toy pistols. KANZLER, M. and ADRIAN, M., (trading as ADRIAN & RODE), Velbert, Rhineland, Germany. May 4, 1931, No. 13141. Convention date, April 23, 1931. [Class 132 (iii).] A toy pistol, e.g. a hundred-shot pistol, with an amorce carrier i on a swing-out plate h pivoted at m having the amorce carrier and the anvil plate k on the same side of the pivot m has the swing-out plate on the opposite side of the pivot m extended into a pistol barrel n. The barrel m has a slot o with which engages the pivot m so that after a fresh amorce strip has been placed on the carrier i the plate h and barrel n can be swung in and slid back so that projections p on the anvil k pass over projections r on the pistol casing and engage in the recesses q in which they are retained by pressure of the hammer b. The hammer b is provided with a cocking member e actuated by the edge f of the trigger lever c, the parts b, c being held in normal position and rapidly restored to normal position after firing by a forked spring g. During firing the amorce strip feed member s presses against the anvil k under pressure of the spring g to hold the barrel in position.

Title: Improvements in or relating to polystyrene derivatives
Inventor: JONES ALUN ANGUS
IPC: C08F8/02
Filed: 1950-05-25
Abstract: Polystyrene of a molecular weight between 20,000 and 150,000 is alkylated with di-, trior tetra - isobutylene, the quantity of isobutylene polymer used being equal in weight to that quantity of diisobutylene which would result in the molar ratio of the diisobutylene to the styrene monomer units in the polystyrene being from 0.5 : 1 to 1.25 : 1.  The alkylation reaction may be carried out by dissolving the polystyrene in a solvent such as monochlorobenzene and then adding a catalyst such as aluminium chloride, a catalyst activator such as acetic acid or nitrobenzene, the isobutylene polymer, and maintaining the temperature of the reaction mixture at 25 DEG  - 30 DEG C.  At the end of the reaction the catalyst is destroyed with hydrochloric acid and the reaction mixture may then either be mixed with lubricating oil, neutralized, filtered, and freed from monochlorobenzene by distillation, leaving the alkylated polystyrene in solution in the lubricating oil as a viscosity index improver, or the addition of the lubricating oil may be omitted and after neutralization and filtration the polystyrene is precipitated from the monochlorobenzene by the addition of an excess of methylated spirit.  Specification 640,566 is referred to.ALSO:Viscosity index improvers for lubricating oils consist of polystyrenes of molecular weights of 20,000 to 150,000 which have been alkylated with di-, tri- or tetra-isobutylene, the quantity of isobutylene polymer used being equal in weight to that quantity of diisobutylene which would result in the molar ratio of the diisobutylene to the styrene monomer units in the polystyrene being from 0.5:1 to 1.25:1.

Title: Improvements in electric telegraphy
IPC: H03M7/40
Filed: 1940-08-26
Abstract: 544,708. Type-printing telegraphy. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 26, 1940, No. 13483. Convention date, Aug. 26, 1939. [Class 40 (iii)] Relates to a tape transmitter for converting cable and like code. signals in which each code combination represents a single character into 5-unit or like code signals in which the same code combination represents one or other of two characters according to the case-shift signal previously transmitted. The case-shift signal is transmitted when, and only when, a change of case is involved. The perfor ated strip 14, Fig. 10 which is fed differentially according to the number of code elements in thc preceding character, is engaged by seven pairs of peckers, one pair 16 17 only being shown The peckers co-operate with seven pairs of levers 45, pivoted on ar oscillating frame 50 and seven pairs of levers 48, Figs. 5 and 10 pivoted at 57, to selec and move to the right in Fig. 10 one or more of 14 selector bars 55, mounted on a race way in a manner described in detail. Across the selector bars 55 is mounted a series of character bars 66, one for each character &c. to be transmitted, and the bars 66 in turn engaging a series of seven Bandot code bars 80, five of which correspond to the five units of the code and the other two control the transmission of the case-shift signals. For each setting of the selector bars 55 a particular bar 66 is selected and moved to position a combination of the five code bars 80 which in turn position five corresponding bars 135 controlling the known cam-operated transmitter 128 to send the five-unit character code signals. Bars 66 corresponding to upper case characters move bar 88, Fig. 14, up and bar 87 down, bars 66 corresponding to lower case characters having the opposite effect. Bars 87, 88 position a bar 141 which is moved to left or right whenever a change of case occurs, thereby opening a contact 156, Fig. 12, in the circuit of a relay 157 which disconnects the normal transmitter contacts 126 and connects up the auxiliary transmitter contacts 138 which send to line one of other of the caseshift signals according to which bar 87 or 88 is depressed by a bar 66. During the transmission of the case-shift signals the operation of the normal transmitter, and the feed of the tape 14, are suspended. If, owing to faulty operation, no character bar is depressed, a special signal is sent to line under the control of an additional " mis-selection " bar 55 and an additional bar 66. The differential feed of the perforated tape 14 according to the number of code elements in the character is effected by a rack 131, Fig. 10, which is moved by a spring-operated arm 24 until it engages a projection 42 on a lever 40, there being one such lever for each pair of peckers 16, 17, the arrangement being such that when either pecker of a pair is operated the arm 42 is moved out of the way of rack 131, which is arrested by the lever 40 corresponding to the first unoperated pair of peckers, namely those opposite a space between two characters in the perforated tape.

Title: Improvements in or relating to a method for chlorinating 3a,4,7,7a,-tetrahydro-4,5,6,7,8,8-hexachloro-4,7-methanoindene and the resulting product
IPC: C07C17/10
Filed: 1951-06-07
Abstract: Chlordene (3a,4,7,7a-tetrahydro-4,5,6,7,8,8-hexachloro - 4,7 - methanoindene) is chlorinated by reacting it with chlorine in the presence of an alumina catalyst.  The chlorination is carried out until not more than about 1.25 and preferably 1 mol. of chlorine has reacted per mol. of chlordene.  The reaction may be effected between about -35 DEG  and 50 DEG  C. and preferably from 0 DEG  to about 30 DEG  C.  The product contains a preponderant amount of 1,4,5,6,7,8,8-heptachloro - 3a,4,7,7a - tetrahydro - 4,7 - methanoindene and also smaller amounts of chlordane (2,3,4,5,6,7,8,8 - octachloro - 3a,4,7,7a - tetrahydro-4,7-methanoindene)and 1,2,3,4,5,6,7,8,8-nonachloro - 3a,4,7,7a - tetrahydro - 4,7 - methanoindene.  The chlorination is preferably carried out in the presence of an inert solvent which is subsequently removed, e.g. by distillation under reduced pressure.  The mixture obtained may be used directly as an insecticide, or the more potent heptachloro compound may be isolated by crystallization or chromatographic means. In an example, chlorine is added to a mixture containing chlordene, carbon tetrachloride and ground alumina while the temperature is maintained at about 25 DEG  C. to yield a product containing 62 per cent of the heptachloro compound, the remainder being chlordane. In a second example, the catalyst is alumina catalyst known as Alcoa Fluid Catalyst XF-21 and the product contains 50 per cent of the heptachloro compound.  Specification 618,432 is referred to.ALSO: 1,4,5,6,7,8,8-Heptachloro-3a,4,7,7a-tetrahydro-4,7-methanoindene and mixtures thereof with the corresponding octachloro compound (chlordane) and nonachloro compound, obtained by the chlorination of chlordene (4,5,6,7,8,8-hexachloro-3a,4,7,7a-tetrahydro-4, 7 - methanoindene) in the presence of an alumina catalyst (see Group IV (b)), are used as insecticides.  The heptachloro compound may be purified by crystallization from solution in methanol, butanol, pentane or hexane.  Examples are given of the effect on roaches of the hepta-, octa- and nonachloro compounds when dissolved in deodorized kerosene.
