Title: Improvements in or relating to the manufacture of polyperfluorochloroolefins
IPC: C08F14/24
Filed: 1949-03-08
Abstract: Perfluorochloroolefines containing no more than one chlorine atom per carbon atom, such as trifluorochloroethylene, are polymerized in the presence of a perhalogenated acyl peroxide such as trichloroacetyl, trifluoroacetyl, dichlorofluoroacetyl, or difluorochloracetyl peroxide, at a temperature sufficiently low, and for a sufficient residence time to produce a normally solid polymer which is hard but not brittle and has a softening point above 150 DEG  C., the residence time not being substantially in excess of seven days, and the temperature not being substantially in excess of 25 DEG  C. or substantially below -20 DEG  C.  Polymerization may be carried out in a batchwise or continuous manner and is preferably effected by introducing the catalyst into the polymerization zone dissolved in a solvent such as trichlorofluoromethane.  The polymers may be after-treated by pyrolysis, filtration, or fluorination. Fluorination may be carried out with fluorine or a fluorinating agent such as antimony pentafluoride or cobalt trifluoride.  The polymers may be moulded, extruded, or formed into sheets.  Specification 578,168 is referred to.  The Specification as open to inspection under Sect. 91, states that perfluorochloroolefines may be polymerized in the presence of other catalysts such as benzoyl and chloroacetyl peroxides, or may be polymerized in the absence of a catalyst or with a less active catalyst at higher temperatures of up to 600 DEG  C. and at pressures of up to 30,000 p.s.i.g.  The perfluorochloroolefines may also be polymerized in the presence of chain transfer agents such as chloroform, carbon tetrachloride, and trichloroethylene, at temperatures above 65 DEG  C. to produce polymer oils, which may be after-treated by pyrolysis, filtration, fluorination, and fractionation by distillation or solvent extraction.  This subject-matter does not appear in the Specification as accepted.ALSO:Perfluorochloro-olefines containing no more than one chlorine atom per carbon atom, such as trifluorochloroethylene, are prepared by dechlorinating a perchlorofluorocarbon, such as 1,2,2 - trichlorotrifluoroethane, in the presence of a metal dechlorinating agent such as zinc, tin, magnesium, iron, and aluminium, and a metal halide solvent such as methyl, ethyl, n-propyl, and n-butyl alcohols, dioxane, glycerol, butyl carbitol, and the solvents known under the Registered Trade Mark "Cellosolve," and then recovering the perfluorochloro-olefine from the products of the dechlorination reaction by distillation. The products are polymerized in the presence of perhalogenated acyl peroxides such as bis-trichloroacetyl peroxide which is prepared by reacting trichloroacetyl chloride with sodium peroxide at -15 DEG  C., and extracting the bis-trichloroacetyl peroxide with trichlorofluoromethane. Specification 578,168 is referred to.

Title: Improvements in or relating to photographic shutters
IPC: G03B9/22
Filed: 1944-04-05
Abstract: 578,971. Photographic shutters. KODAK, Ltd. April 5, 1944, No. 6366. Convention date, May 4, 1943. [Class 98 (i)] The master member of a photographic shutter carries two spaced protuberances which during the operation of the shutter engage an arm projecting from the bladeoperating ring, one protuberance engaging and moving the arm in one direction to open the shutter and the other engaging and moving the arm in the opposite direction to close the shutter. The shutter blades 4 are pivoted and carry pins 6 which engage in slots 7 in the blade ring 8. An arm 9 extends upwardly from the ring 8 and carries an angular cam 13 at its upper end 12: The master member 15 has a blade-opening pin 19 and bladeclosing pin 20, the former with a bevelled edge 40. A slot 22 in the master member 15 permariently engages a pin 23 carried by the arcuate arm 24. A projection 26 on the arm 24 projects into the path of a pivoted latch 27 carried by the trigger arm 29. In operation, the finger-piece 30 is pressed downwardly and in the early stages rotates the master member 15 against the spring 17 from the position in Fig. 1 to that in Fig. 2, the bevelled edge 40 of the pin 19 riding under the end 12 of the blade arm 9. The end 41 of the latch 27 then strikes a cam 42 and the arm 24 is released and returns under the influence of the spring 17. During this movement, the pin 19 gains momentum quickly before striking the cam surface 13 of the arm 9 and rocking the blade ring to open the shutter blades. After a small further movement, the pin 19 swings past the top edge of the arm 9 and the master member continues rotating until the pin 20 hits the arm 9 in a reverse direction and closes the shutter.

IPC: G02B21/00
Filed: 1953-03-09
Abstract: 724,562. Optical-gauging apparatus. SOC. GENEVOISE D'INSTRUMENTS DE PHYSIQUE. March 9, 1953 [March 14, 1952], No. 6420/53. Addition to 704,267. Class 106 (2). The apparatus described in the parent Specification is modified to allow the examination of a cross-section of a workpiece, such as a turbine blade, having a flange or shoulder 6a at its upper end. The turbine blade 6 to be examined is located in similar manner to that described in the parent Specification on the optical axis AA so that illumination from lamps 8 and condensers 10 falls on the part BB as sharply defined by the sleeve 12. The light from the illuminated portion is reflected from a mirror 19 through an objective lens 2 on to a screen 3 via mirrors 4, 5, so that the device according to the invention is characterized by a mirror perpendicular to the optical axis, surrounding the part to be examined which extends through the mirror, while the illuminating means are located in a plane located between the objective and the mirror so that the latter is constrained to return towards the objective, the rays of the flat beam of light reflected by the part undergoing examination onto the mirror. The mirror 19 is preferably in two portions 19a, 19b, as shown in Fig. 2, shaped to fit closely to the shape of the turbine blade 6. In a modification shown in Fig. 3 the mirror 19 is replaced by a semi-transparent sheet 26, and a second arrangement of lamps 27 and condensers 28 and a shield 30 is arranged below the sheet 26. The arrangement is such that the optical distance C-D-E is equal to the optical distance B-D-E so that two crosssectional images may be focused and examined simultaneously on the viewing screen. The area CC being examined by the direct rays passing through the sheet 26, and the area BB being examined by the reflected ray B-D-E being reflected by the sheet 26. It is thus possible to examine simultaneously the two terminal cross-sections of the blades and thereby to check the modifications in the angles of the leading and trailing edges thereof.

Title: Improvements in or relating to telephone systems
IPC: H04M17/02
Filed: 1920-03-04
Abstract: 164,135. Automatic Telephone Manufacturing Co., Ltd., and Savin, J. March 4, 1920. Coin-freed and metering systems.-Arrangements are made whereby a subscriber cannot make a call without performing an operation distinct from that of lifting the receiver. If the call is effective, the usual current reversal in the case of automatic exchange systems effects the operation of the meter or the collection of the coin; if the call is non-effective, the coin may be recovered by the subscriber. In the system shown in Fig. 1, the subscriber after lifting the receiver 1 cannot effectively dial his call since the dialsprings 11 are short-circuited by the circuit 1, 4, contact 5, and contact 9. On pressing the key 6, however, the contact 5 is broken and the magnet 8 is energized, tilting its polarized armature 7 so as to break the short-circuit at the contact 9. At the same time, the pawl 12 is forced by the spring 13 to engage the next tooth of the ratchet 14 of the meter. If the call is effective, the reversal of the line current restores the armature 7 to the position shown, thus metering the call and' providing a circuit for the conversation. In manual exchange systems, the button 6 is operated at the operator's request and by earthing the line furnishes a signal at the exchange. In a modification, a coin performs the same function as the buton 6. It is retained bv the armature 7 until communication is established when it is collected. In a further modification, Fig. 3, the coin is returned to the caller if the call is non- effective by movement of the rod 18, the collet 20 at the same time breaking circuit with the exchange to prevent fraud. A dash-pot 25 prevents too rapid movement of the rod 18. In case the caller forgets to recover a coin, means are provided whereby hanging up the receiver or, according to the Provisional Specification, leaving the telephone box, effects its collection. As shown, hanging up the receiver completes a circuit through the contact 24 and an auxiliary winding 22 on the magnet 8 which causes restoration of the armature to the normal position.
