Title: Improvements in keyless locks
IPC: E05B37/16
Filed: 1921-10-13
Abstract: 191,799. Raydon, L. G. Oct. 13, 1921. Locks, permutation.-A hand-shot spring-retracted bolt is held in its shot position by the recessed shanks of rotatable permutation buttons and by a pin on a disc entering a slot in the bolt, release being effected by setting the permutation buttons and by rotating the disc step by step to release the pin carried by it, by pushing in certain of a number of similar push buttons in a predetermined order. In the form shown in Figs. 8 and 9, the bolt a, shot by its knob a<3>, has a recess a<1> engaged by a pin d on the disc c. This disc has a number of holes c<1> - - c<4> with inclined sides to co-operate with the conical or inclined ends of spring press-buttons 1 - - 4. Two rotating permutation buttons 5, 6 have recessed shanks engaging recesses in the bolt. After the buttons 5, 6 have been set so that they do not obstruct the bolt, the pin d is released from the bolt, allowing it to be retracted by its spring, bv pressing in the push buttons in the order 1 - - 4. The insertion of the button 1 into the recess c<1> rotates the disc sufficiently to bring the hole c<2> below the button 2, which, on insertion, rotates the disc another step and allows the insertion of button 3 and so on, the pin d moving step by step out of the slot a<1>. Operation of a button in its wrong order reverses the movement of the disc and brings the pin d a step further into the slot a<1>. Dummy buttons may be provided. The buttons may be arranged round the disc as shown in Fig. 7, the disc having a flange with holes cut in it to coact with the wedge-shaped ends of the push buttons 1 - - 4. The rotatable buttons 6, of which only one is shown, are in this case recessed and are turned to allow the bolt to pass through their recesses. The heads of the rotatable shanks are squared so that the buttons may be removed and replaced in different positions relative to the shanks to change the combination.
Patent GB-1193297-A (GB)
Title: Device for the Fine Adjustment of Photomasks with respect to Semiconductor Elements
IPC: G03F7/20
Filed: 1967-06-13
Abstract: 1,193,297. Semi-conductor devices. TELEFUNKEN PATENTVERWERTUNGSG.m.b.H. 13 June, 1967 [1 July, 1966], No. 27247/67. Heading H1K. [Also in Division G2] The position of a photomask relative to that of a semi-conductor element is adjusted by means of rod-shaped electro-mechanical transducers. As shown, Fig. 1, after a preliminary coarse adjustment, a photomask 4 mounted on a carrier 5 is positioned over a semi-conductor element 1, by two magneto-strictive transducers 10, 11. The correct position is determined by aligning two apertures 6 in mask 4 with corresponding pairs of apertures 3a, 3b, in the semiconductor element and base-plate respectively. Detection is by means of a radiation source 7 and a pair of photo-diodes 8 connected to an indicator 9. The transducers 10, 11 are energized by means of D.C. sources 16, 17 and variable resistors 14, 15 and may have superimposed A.C. energization from sources 18, 19 to produce a small oscillation of the mask. The photo-diode may be connected to a phasesensitive rectifier, the output of which is zero when the mean position of the mask is correctly positioned. The output of the measuring circuit can be used to control the current applied to the transducers to provide an automatic positioning system. Instead of bores 3a the semiconductor element 1 may have thin regions through which the radiation is transmitted and if IR radiation is used the bores may be omitted altogether if the element is sufficiently thin. In a modification of the sensing system, Fig. 3 (not shown), a pair of light reflective spots are provided on the surface of semi-conductor element 1 instead of the bores 3a, 3b, and the mask is positioned using an incident light microscope situated above the aperture in the mask. A photo-cell can be used to provide a control voltage for an automatic positioning system. The system can be adapted to provide for rotation of the mask by replacing each of the single transducers 10, 11 by a pair of parallel transducers, differences in energization of the transducers rotating the mask, Fig. 2 (not shown). In an automatic system the A.C. supplies to the various transducers can have different frequencies to aid the production of the required control signals. If necessary the mask carrier can be supported by thin bearing rods extending perpendicularly to the plane of the mask, and these rods may comprise transducers for adjusting the height of the mask above the surface of the semiconductor element. The transducers may also comprise electrostrictive or piezo-electric rods. The positioning device may also be utilized for adjusting a mask in a projection process.

Title: Improvements in or relating to the manufacture of electric cables
IPC: H01B3/08
Filed: 1948-10-20
Abstract: Asbestos is subjected to pulverization while hot and then to calcination prior to use as insulation in electric cables.  During the pulverization the asbestos is ground to a powder which will pass through a sieve of approximately 900 mesh per square centimetre, and is then compressed into blocks which are calcined at a temperature of over 800 DEG  C.  The blocks thus formed are inserted in a workpiece comprising one or more conducting cores and a metallic sheath.  The workpiece is reduced to the desired dimensions by successive steps of mechanical working with or without one or more annealing stages.  The calcination process is said to reduce the hygroscopic tendency of the asbestos.

Title: Improvements in and relating to flame-proofing agents containing titanium and antimony
Inventor: LANE FRANK WESLEY
IPC: D06M11/20
Filed: 1950-11-10
Abstract: A flame-proofing agent for cellulosic and certain other materials comprises a water-soluble complex compound of antimony and titanium, the negative radical in which is derived from a monobasic acid, e.g. nitric, hydrobromic, hydroiodic, but preferably hydrochloric.  The agent is suitably used in monobasic acid solution, the acid value being less than that required to form the normal salts of the titanium and antimony.  The solution may be produced by combining titanium tetrachloride with antimony oxide in the presence of water so that a ratio of 1 mol. H Cl for each 2 mols. titanyl chloride and also for each mol. antimony chloride exists.  Preferably there is present not less than 2.5 atoms chloride ions over and above those present in each molecule antimony chloride.  The solution contains 25-500 grams/litre combined titanium and antimony oxides. Alternatively, a dry product may be obtained by reacting 1 mol. antimony oxide with 1-4 mols. titanium tetrachloride.  Fuming of the product in a moist atmosphere may be avoided by adding a little water to react with residual titanium tetrachloride.  The product dissolves in hydrochloric, chloracetic, acetic, &c. acids.  Other monobasic acid compounds of titanium and antimony may also be mixed.
