Title: Method of and apparatus for fixing fittings on glass panels
IPC: B22D19/00
Filed: 1965-06-21
Abstract: 1,080,271. Casting composite articles. COMPAGNIE DE SAINT-GOBAIN. June 21, 1965 [June 20, 1964], No. 26121/65. Heading B3F. [Also in Division B5] In a method of attaching fittings to glass panels in which the fittings are east in position on the panel, the panel is moved to a casting station on a roller conveyer and is accurately positioned against stops 19 and 20. Fluid means 25 lower the conveyer portion with the panel so that it is located on the lower half moulds 22, 23, 23<SP>1</SP>, and the upper half moulds 26, 27, 27<SP>1</SP> are then lowered by fluid means 30 on to the panel. The completed mould has a cavity which forms a casting with a part on each side of the glass panel interconnected by a bridge portion. The material to be cast which may be metal or plastics material is then injected into the moulds. The materials chosen for casting are those which have a greater contraction that the glass so that on cooling the finished cast fitting grips the panel. The particular fittings described include hinges and locks for glass doors.

Title: A device for advancing shrinkable and stretchable web materials such as textile fabrics
IPC: D06B23/04
Filed: 1951-11-08
Abstract: 735,341. Feeding webs. RYDBOHOLMS AKTIEBOLAG. Nov. 8, 1951 [Feb. 22, 1951], No. 26163/51. Class 100 (1). Web material 4, such as textile fabric, is fed from a pile 5 over a roller 6 to a bath 3 containing liquid wherein it passes around rollers 7, 8, 9, 10 and 11. The rollers 7, 9, and 11, are driven from shafts 15, 19, and 23 by belts of rubber or similar material which is more elastic than the material being fed. If the material shrinks in length between the rollers 9 and 11, the roller 11 rotates at a correspondingly lower speed, since the taut portion of the belt driving that roller is stretched, while the slack portion is correspondingly contracted, such that speed of the roller 11 is adapted to the resistance of the fabric passing over it. Similarly, if the material stretches between the rollers 9 and 11 the speed of the roller 11 is increased. Feed rollers 28 and 29 are driven at such a speed that a loop 30 is formed between a roller 27 and the rollers 28, 29, the length of the loop being controlled by a detector roller 31 carrying a rod 34 operable to engage limit switches 36 and 35 which control, through relays, the speed of a motor driving the rollers 28, 29.

Abstract: 1304562 Bowling scoring system BRUNSWICK CORP 2 June 1970 [5 June 1969] 26680/70 Heading A6D A bowling scoring system including an automatic pinsetter, pinfall detecting means, manually operable bowler identification means and a scoring computer, is modified by the addition of manually operable practice bowling indicator means and means responsive to the indication given preventing computer action on practice scores. Each of a plurality of bowling lanes e.g. 10, 11, is provided with an automatic pinsetter APL, APR, which is cyclically operable to set new pins in its associated lane and includes a rake 13 movable to a lane blocking position either if a bowler fails to identify himself through a bowler identification console 15 or to clear deadwood from the associated bowling lane A pinfall detector is provided for each lane to determine pinfall after each ball is bowled in the associated lane, and a score computer is connected to all the pinfall detectors to receive pinfall information and convert it into frame-by-frame bowling scores. Bowler identification means for each bowler is provided on console 15, and includes at least one manual operator to be actuated by a bowler before rolling the first ball in a scoring frame to enable that bowler's pinfall in that frame to be credited to him by the computer. An interlock is operative to stop the pinsetter with its rake in the lane blocking position when the bowler identification means for that lane has not been operated by the bowler and also disables the automatic pinsetter and the pinfall detector for that particular lane. Manually operable practice bowling signalling means is provided to be operable by a bowler in order that a ball may be bowled without the computer scoring the result and means responsive to a signal from the practice bowling signalling means precludes pinfall information from being utilised by the computer by disabling either the computer or the pinfall detector, and signals the interlock to raise the rake from the lane blocking position to enable a practice ball to be bowled.

Abstract: 806,792. Electric signal transmission systems. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. May 7, 1957 [Aug. 31, 1956], No. 26681/56. Class 40 (4). [Also in Group XL (c)] In a signal delay circuit the signals to be delayed are applied to a short-circuited delay line the two-way delay of which is equal to the required delay of the signal. The input of the line is applied to one discharge tube and the undelayed signals to the other discharge tube of a differential amplifier so that only the delayed signal appears at its output. The Figure shows the application to a pulse delaying circuit in which the positive input pulse is supplied at 1 to a cathode follower stage 2 across the output load 3 of which is connected a delay line 4 shortcircuited at its distant end the two-way delay of which is equal to the required delay to be given to the input pulse. The resistance 3 is equal to the characteristic impedance of the line 4 so that after reflection at the output end a composite pulse is produced at the input end of the line comprising a positive pulse followed by a delayed negative pulse. This signal is applied to one tube 6 of a differential amplifier to the grid of the other tube 5 of which the undelayed input signal is applied and the resistors 7, 8 are adjusted so that the output 9 of the differential amplifier comprises only the delayed pulse required, the undelayed pulse being balanced out.

When throttle 2 is closed or slightly open atmospheric pressure is communicated to chamber 8a so that the obturator is held in the closed position to prevent exhaust recycling. When orifices 10a, 10b lie respectively upstream and downstream of the edge of the throttle 2 the obturator is lifted to allow some recycling and when both orifices are upstream of the edge of throttle 2 the obturator is lifted to allow full recycling. At fully open throttle positions the increase of pressure in chamber 8a closes the obturator. Orifice 17 prevents pulse transmission to chamber 8a. Obturator 6 may have an edge formed as a scraper to remove deposits from passage 5a.

Abstract: An elastomer is made by reacting (a) a siloxane of the formula HO[SiR2O]nH, (b) a silane of the formula R1Si(OAc)3 or Si(OAc)4 in amount such that there is at least 0,33 mol. of R1Si(OAc)3 or at least 0,25 mol. of Si(OAc)4 per mol. of Si-bonded OH group in siloxane (a), and (c) MgO in amount such that there is at least 1,5 mols. of MgO per mol. of silane (b), wherein each Ac is a saturated aliphatic monoacyl radical derived from a carboxylic acid, each R and R1 is a monovalent hydrocarbon or halogenated hydrocarbon (saturated or unsaturated) or cyanoalkyl radical, and n is an integer of at least 5.  In a modification, a part of siloxane (a) may be reacted at room temperature with silane (b) to form a reactive intermediate (d) of the formula (AcO)2SiR1O[R2SiO]nSiR1(OAc)2 or (AcO)3SiO[R2SiO]nSi(OAc)3, which can be substituted for silane (b) in the elastomer-forming process. Reaction occurs spontaneously upon mixing the above reactants, usually at a temperature within the range of 15 DEG  to 100 DEG C., to produce a cured rubber.  Plasticizers, dielectric materials, oxidation inhibitors, heat stability additives, pigments and fillers such as reinforcing silica fillers which have been hydrophobed as described in Specification 699,759, may also be added.  In typical examples (1) methyl triacetoxy silane and MgO were added to a base composition consisting of two liquid 3.3.3-trifluoropropylmethyl siloxanes, one having terminal OH groups and the other terminal methyl radicals, a hydrophobed reinforcing silica and powdered Al, and the resulting mixture was poured into a container and cured in 18 hours at room temperature; and (6) MgO and HO[Si(CH3)2O]300H were dispersed in a petroleum ether solution of a gum of the formula HO[Si(CH3)2O]3000H, a trimethylsilyl-surface modified SiO2 and methyl triacetoxysilane and the resulting composition cured, after application to a metal panel, to a tough rubber in 18 hours at 200 DEG C.
