Title: Improvements in yarns coated with synthetic thermoplastic material
Inventor: JACKSON ALBERT EDMUND
IPC: B29C48/06
Filed: 1965-02-03
Abstract: 1,079,551. Moulding by extrusion. GEORGE ANGUS & CO. Ltd. Jan. 31, 1966 [Feb. 3, 1965], No. 4757/65. Heading B5A. Thermal degradation of a core 10 of continuous or spun natural or synthetic fibres is reduced when extrusion coated with molten, thermoplastics material 23 by passing the core through a cooled mandrel 18 which is also thermally insulated from die head 14. As shown, mandrel 18 is housed within a sleeve 24 and is heat-insulated therefrom by rings 19. Sleeve 24 causes the formation of a conical tube 25 which is drawn on to core 10 by applying a vacuum via line 28 and the thickness of tube 25 may be varied by rotating sleeve 24 which is screwed at 29 into the die head. Water is circulated in mandrel 18 via lines 19 and 26. In a second embodiment, Fig. 1 (not shown), sleeve 24 is dispensed with. Core 10 is cooled before reaching the die head by, for example, placing a bobbin of the material in a refrigerated environment, by passing the core through a tunnel of refrigerated air or through a bath of cooled non-wetting liquid, e.g. mercury, or by passing the core over drums or rollers containing a freezing mixture or low temperature refrigerant. The coated core is cooled, possibly by one of the above-mentioned means. Core 10 is passed through die head 14 at a linear speed of up to 3500 ft./min. and may be stretched to counteract shrinkage, e.g. by rotating take-off rolls (17), Fig. 3 (not shown), at a higher rate than feed rolls (11). The core material may be of polypropylene, nylon, polyethylene teraphthalate, polyethylene, polyvinyl alcohol or polyvinylidene chloride and the coating material may be of plasticized or unplasticized PVC, nylon, polypropylene, fluorinated thermoplastics or elastomeric polyurethanes.

Title: Improvements in or relating to the fire-proofing of rubber
IPC: C08K3/36
Filed: 1942-04-10
Abstract: Natural or synthetic rubber, balata and guttapercha are rendered fireproof by admixture with a gel obtained by hydrolysing a silicon ester and removing the alcohol.  The hydrolysis may be effected by means of a salt having fireproofing properties such as ammonia, boric acid or magnesium chloride.  In an example, a solution of ethyl silicate in industrial spirit is admixed with an aqueous solution of ammonium chloride and boric acid and a solution of magnesium chloride is added.  A heavy gelatinous precipitate forms and is redissolved by addition of further ethyl silicate solution.  The solution is evaporated at 100 DEG  C. until a firm gel is obtained and this is incorporated with rubber either in an internal mixer or on mixing rolls. Specification 574,548, [Group IV], is referred to.

A blank 102 is carried by slidable pivotally mounted gripping arms 312, 314 arranged to open on retraction when arm 316 engages cam 317. Each document carrier is provided with teeth co-operating with a pivotally mounted stop (Figs. 5, 6, not shown) to locate the card in a column reading or punching position. Gaps may be provided in the teeth to allow portions of either the read or the data receiving card to be passed over. The data sensor has a punch block 120 reciprocating in channels 128 in a side frame of the reader and moved by bell crank 121 and eccentric 122 on shaft 123. The punch block carries a document sensing arm 140 pivotally mounted to the block and spring loaded to move sensing fingers 143 towards the document 101. The sensing arm has a portion 141 arranged to contact a pivotally mounted interposer arm 160 coupled to arm 140 by spring 175. Block 120 carries a punch 111 sliding in guide block 112 and co-operating with die 110 to perforate document 102 if a perforation exists in document 101. During movement of a document, cam 170 holds arm 140 away from the document and block 120 is partly retracted. When both documents are stationary a clutch is operated to rotate a shaft 123 and cam 170. Block 120 is raised and arm 140 is released. If a perforation is sensed arm 141 moves arm 160 to a position as shown wherein end 166 of arm 160 is situated between block 120 and punch 111. As block 120 is retracted projection 165 of arm 160 is retained in hollow 125 in block 120 and the punch is moved while the sensor is withdrawn from document 101. If a perforation is not present (Fig. 2, not shown) projection 165 is situated below hollow 124 and when block 120 is retracted punch 111 is not moved. The punch may be coupled to a relay 180 to provide electrical output signals or an output switch may be operated by arm 141 or arm 160.

Abstract: 1450464 Electronic timepieces CITIZEN WATCH CO Ltd 4 Feb 1974 04945/74 Heading G3T In an electronic timepiece comprising a reference oscillator 1, e.g. a crystal oscillator, a frequency divider 2, a counter 3 and a display mechanism 4, the frequency of the oscillator 1 is compensated for variation with temperature by circuitry 5 including a temperature detector 6 which delivers a signal when the temperature exceeds a predetermined level. Preferably the device 6 is a transistor (Tr1) Fig. 5 (not shown) or a diode (D 3 ) Fig. 10 (not shown) e.g. a Schottky diode, and a voltage is applied thereto which, at the predetermined temperature, is the devices threshold voltage, so that when this temperature is reached a digital output signal is changed. To the detector 6 may be connected a buffer amplifier and a constant voltage circuit Figs. 6-9 (not shown). The temperature compensating circuitry 5 futher comprises a voltage generator 9, Figs. 16, 17, which, under the control of a coded signal generator 10 e.g. a shift register, applies a voltage to the temperature detector 6. The digital output signal of detector 6 is fed to a signal discriminator 11. In the embodiment of Fig. 16 the output of discriminator 11 is fed to logic circuitry 12 which adds extra pulses to the input to divider 2 from oscillator 1. In the embodiment of Figs. 3, 17 the discriminator output is fed to switch circuitry TG1-4 which stabilizes oscillator 1 against frequency variation with temperature by selectively switching in capacitors in parallel with the oscillator. The device 5 may contain a plurality of detectors (6a-d) Fig. 11 (not shown) the respective digital outputs of which change at different temperatures. By feeding the outputs through logic circuitry (7) the frequency-temperature characteristic of the oscillator 1 is corrected a plurality of times withing a given temperature range Fig. 12 (not shown).  In the embodiment of Fig. 13, the base electrodes of a plurality of transistors are connected via resistors R b1 -R Bn  to respective sliders which engage a common potentiometer Ro. Alternatively the connections to Ro may be fixed, Fig. 14 (not shown). In either case part of Ro may be variable or replaceable to enable the embodiments to be used with oscillators having different frequency temperature characterization.
