Patent GB-390097-A (GB)
Title: Improvements in the manufacture of rubber chlorination products
IPC: C08C19/04
Filed: 1932-10-26
Abstract: Rubber latices are subjected to an oxidizing process, and subsequently to chlorination to produce a chlorinated rubber soluble in organic solvents.  The oxidation may be performed by the addition of hydrogen peroxide, or by the passing of air or oxygen through the latex; it is accelerated by the addition of catalysts such as ferric chloride, nickel sulphate, cobalt nitrate, copper sulphate, manganese sulphate, copper oleate, cobalt linoleate, or by exposure to light. The chlorination may be performed with the addition of agents such as aluminium chloride, ferric chloride, or phosphorus oxychloride, capable of splitting off hydrochloric acid.  The chlorinated rubber may be stabilized as in Specification 383,154.  The term latex includes natural, concentrated, purified, agglomerated latices, artificial dispersions of rubber, and emulsions of polymerized butadiene, isoprene, &c.  Numerous examples are given, of which the following is typical: 30 parts of a 25 per cent solution of sodium salt of dibutylnaphthalene sulphonic acid are added to 40 parts of a 60 per cent latex concentrate.  Oxygen containing 6 per cent ozone is bubbled through at 20 litres per hour for 2 hours at room temperature.  Chlorine is then introduced at 40 DEG  C. until chlorinated rubber containing 40-60 per cent chlorine is obtained. This is filtered and dried, and yields a white powder soluble in benzene, tetrachlormethane and tetrahydronaphthalene.

Title: Electric power supply systems
IPC: B60R21/01
Filed: 1972-06-27
Abstract: 1387446 DC supply systems; protective arrangements NISSAN MOTOR CO Ltd 27 June 1972 [30 June 1971] 30104/72 Headings H2H and H2K A power supply system comprises a D.C. power source 11, a first rectifier 14, a series circuit including a resistor 12 and a capacitor 15, a second rectifier 23 connected in parallel with the resistor and a circuit for monitoring the conduction of the capacitor 15. A load R L , which may be the actuator of a protector bag for preventing injury to motor vehicle passengers during a collision, is connected across terminals 17, 18. When a key switch 13 is closed the capacitor 15 is charged and is discharged through the load via the rectifier 23 when a switch 16 is closed. The capacitor 15 enables power to be supplied to the load if the battery 11 becomes disconnected and the monitor circuit, including comparators 38, 39 and NAND gates 40, 41, indicates deterioration or breakage of the capacitor 15. The comparator 39 produces a logical "1" output when the voltage at a point J3 of an R-C circuit 35, 36 exceeds the reference voltage at a point J2 of a potential divider 33, 34. Similarly the comparator 38 produces a logical "1" output when the voltage at a point J1 exceeds that at the point J2. The time constant of the R-C circuit 35, 36 is small compared with that of the R-C circuit 12, 15 provided that the capacitor 15 is in its normal condition so that a logical "1" signal is present on a terminal 45. Decrease of the capacitance of the capacitor 15 due to deterioration causes a logical "0" signal to appear at the terminal 45 whilst short circuiting of the capacitor 15 produces a logical "0" signal at a terminal 43.

Title: Improvements in temperature indicating and regulating apparatus
IPC: G05D23/24
Filed: 1936-11-06
Abstract: 486,762. Measuring currents. MOREAU, H. Nov. 6, 1936, No. 30310. Convention date, Nov. 6, 1935. [Class 37] [Also in Group XXXV] In a temperature regulating and indicating device comprising galvanometer coils 1, 2, connected in series with temperature sensitive coils 3, 4, the resistances of which are relatively variable'with variations in the temperature to be regulated, the galvanometer needle 5 is adapted on deflection to engage one of two contacts 6, 7, as a result of which the appropriate coil 3, 4 is shunted by a relay 15 of less resistance than the shunted coil so that a firm contact between the needle 5 and the contact 6 or 7 is obtained, the relay 15 serving to close the circuit of a temperature regulating relay 37 or 25 and of an electromagnet 8 or 9 corresponding to the engaged contact piece so that the latter is retracted by the electromagnet and the temperature can be indicated by the position of the needle. The resistance 3 varies with temperature and as the temperature falls the needle 5 engages contact 7 which is in its outer position. As a result the low resistance relay 15 is energized which operates switches 18, 20, 22 to their closed positions and thus energizes relay 25, which moves switches 16, 27, 34 to the dotted positions shown. Electromagnet 8 is thereby de-energized so that contact 6 moves into the path of the needle 5, relay 15 is de-energized thereby opening switches 18, 20, 22, and switch 34 puts into action a servomotor which starts burners &c. for raising the temperature. Electromagnet 9 is energized by the closing of contacts 40, 27, and the contact piece 7 is withdrawn from the path of the needle 5 which can therefore indicate the temperature. As this rises the needle approaches contact 6 and if it engages therewith, relay 15 is again energized and coil 4 is shunted thereby. Switches 18, 20, 22 are again closed, whereby relay 39 is energized and restores switches 16, 27, 34 to the full line positions, thus stopping the additional burners, energizing the electromagnet 8 to remove the contact 6 from the needle path and de-energizing the electromagnet 9. If, after engagement of the needle with the contact 7 and the retraction of the latter from the needle path, the temperature continues to fall, the needle engages contact 8a, as a result of which the coil 4 is shunted by a low-resistance relay 42, which closes a switch 45, energizing a relay 48. This closes contacts 49, 50 for operating an alarm and if necessary inserting other burners. The temperature thus rises rapidly and if contact is made between the needle and contact piece 6, the relay 52 is energized in addition to the effects enumerated above and opens the contact 49, 50 to cut out the additional burners. A contact similar to the contact 8a may be provided beyond the contact 6, and all the contacts 6, 7, 8a are adjustable on their support 10, contact 8a being insulated therefrom.

Filed: 1939-11-20
Abstract: 581,001. Photographic diazotype processes. FRANGIALLI, P. Nov. 20, 1939, No. 30407. Convention date, Nov. 19, 1938. [Class 98 (ii)] Positive images are obtained using a lightsensitive diazo compound capable of coupling with a product of its light-decomposition to give an azo dye by exposing under an original (such as a drawing) on a translucent carrier to highly actinic illumination, removing the original, and giving an exposure to slightly actinic illumination or for a short period to an actinic source. The strongly actinic light for the first exposure may be a carbon arc, and the light for the second exposure Wood's light, diffuse daylight, or a high-pressure mercury vapour lamp. A short exposure to the carbon arc may, alternatively, be given. The paper may be damped between the two exposures, and may be allowed to remain in the dark after the second exposure to allow coupling to take place. Hygroscopic substances such as glycerol or glycol may be added to the sensitive material. Urea may also be added. The diazo compound may be an iminazole derivative, for example the diazo compound from C-methylamino-4- naphthiminazole. The Specification as open to inspection under Sect. 91 states that with pencil drawings with slightly opaque lines, the second exposure is unnecessary. This subject-matter does not appear in the Specification as accepted.

Abstract: 461,365. Automatic guns. BIRKIGT, M. Nov. 4, 1935, No. 30431. Convention date, Sept. 16. [Class 92 (ii)] Relates to automatic guns of the kind in which the striker post 7, Fig. 3, is movable relatively to the breech block 6 to release a looking latch 13, Fig. 1, pivoted to the block which engages a notch 15 in the gun casing, the latch serving also by engagement with a recess 19 in the post to lock the parts 6, 7 together throughout the opening and closing movements of the block and until the latch re-engages the notch 15 when the post is released for firing. According to the invention, the abutment surfaces between the recess 19 and the latch are at right angles to the latch so that during closing there is no lateral force tending to press the latch against the guide surface 24, and, further, the latch has a surface 20 engaging at the end of the closing movement a fixed incline 21 on the casing to start the movement of the latch into the notch 15. In the form shown, a gas-operated piston acts through rods s to move the post 7 rearwards relatively to the breech block the latch 13 being released from the notch 15 by the engagement of inclines 17, 16. The portion 14 of the latch is then moved into the recess 19 to lock the parts 6, 7 together whilst the breech block is moved rearwards by the gas pressure on the cartridge case. On the return movement, the post 7, pressed forward by the return spring 5, engages the latch by perpendicular surfaces y, and, when the breech block reaches the closed position, the locking rotation of the latch started by the surfaces 20, 21 is completed by an incline 23 on the post.

Filed: 1956-10-08
Abstract: 830,216. Lift control systems. INVENTIO A.G. Oct. 8, 1956 [Oct. 19, 1955], No. 30540/56. Class 78 (3). A lift control device for arranging the order in which landing calls are answered, comprises a selector which searches the landing call circuit step by step in a predetermined order and causes the calls to be answered in that order. The selector comprises arms 1, 2 which are moved clockwise only over contacts 3-6 and 7-10 by a motor 12, and the circuit includes landing push button switches 131-134, which are operatively connected by means (not shown) with contacts 141-144, relays 151-154 which each control movement of the car to a selected floor, door closed switches 19, a floor switch 20, slow to close contacts 18 which are closed when the car is braked, and a relay 17 having contacts 171, 172. In operation, closing of one landing switch, e.g. 133, also closes contacts 143 thereby causing the arms 1, 2 to move to contacts 5, 9 whereupon relay 17 is energized so stopping motor 12 and, if switches 18-20 are closed, closing a circuit to relay 153 which then drives the car to the third floor. As soon as the car is free again the arms 1, 2 move clockwise to select the next operated landing call. According to a modification (Fig. 2, not shown) the apparatus is incorporated in a system having means for storing landing calls. In a further modification (Fig. 3, not shown) the device modifies a system of the kind in which the car normally moves to the highest unanswered down call then answers registered down calls in turn until fully loaded whereafter it passes further down calls, by causing the car to return to the highest previously passed down call on its next run. If one stop is of greater importance than the others the sets of contacts 3-6, 7-10 may each include more than one contact for that floor.
