Abstract: 1340968 Locks DAIMLER-BENZ AG 28 Oct 1971 [2 Nov 1970] 50209/71 Heading E2A A steering lock for a vehicle comprises a lock casing 3 carrying a cylinder lock mechanism 2 which includes a housing 4 containing a rotatable cylinder 5 carrying plate type tumblers 6, a cap 15 with an annular extension 16 securing the lock mechanism to the casing and a locking pin 8, which is disposed in an opening in the housing, is urged outwardly by a spring 12 and extends through the casing and engages in a groove 14 in the said extension which is made of high strength material, an aperture 9 being provided in the cylinder to permit dismantling of the lock, the aperture being in the region of an end portion of one of the tumblers and being intended to receive the end portion of the locking pin such end portion being shaped so that when the pin is in the aperture in which position it is disengaged from the groove in the extension, movement of the tumbler is not impeded. The lock is dismantled by first inserting the key in the cylinder and turning the cylinder until the aperture is underneath the pin 14; the cap can then be partially drawn off the casing since the shape of the groove and the shape of the end of the pin is such that withdrawing movement of the cap forces the pin into the aperture; the cap can be withdrawn to a position which enables the spring to move the pin either into a recess 17 in the cap or beyond the end of the cap and this frees the cylinder for rotation by the key to the position in which the key can be withdrawn; the cap can then be completely removed. As shown the end portion of the pin which engages in the aperture is slotted so that movement of the pin into the aperture is not prevented since the end portion of the tumbler enters the slot, sides of the pin end portion are also recessed to clear neighbouring tumblers.

Abstract: 1,267,788. Coupling together optical glass fibres. STANDARD TELEPHONES & CABLES Ltd. 27 Oct., 1970, No. 50956/70. Heading C1H. To couple together end to end, two optical glass fibres, each comprising a core and cladding sheath, the ends of the fibres are formed into substantially plane faces which are butted together in a two-part glass jig made of a glass having a fusion temperature matched to the glass diffusion temperature of the fibres, the jig then being heated to cause fusion of the two parts of the jig, which thereby retains the fibre ends under light radial compression, and to cause the diffusion of the core and cladding glasses into each other adjacent the ends. The jigs two parts 1 and 2 hold the fibre ends 4 in a right-angled groove 3 of such depth that before heating, the fibre 4 is just above the level of the lower part 2 so that on fusion, there is light pressure to hold the fibre ends in position. Diffusion of the core and cladding glasses allows for any slight mismatch or eccentricity of the fibre cores.

Title: Document reading apparatus
IPC: G06V10/12
Filed: 1973-11-07
Abstract: 1443527 Character recognition systems INTERNATIONAL BUSINESS MACHINES CORP 7 Nov 1973 [26 Dec 1972] 51660/73 Heading G4R A document reading apparatus includes a guide surface on which a character-bearing document to be machine read is placed. The surface has an array of elements which are energized in turn to radiate a signal through the document, each element having such a position that it lies beneath a respective character on the document. A read head placed over a character on the document senses the radiated signal which, by its time of occurrence, is indicative of the position of the character. In addition the radiated signal is used to determine any misorientation or off-centring of the read head relative to the element. The read head also scans the character to generate signals for recognition purposes. The guide surface in the embodiment described has stops against which the document is placed so that the characters on the document are correctly positioned over the elements. Each element comprises a crossed array of infra-red light-emitting diodes, e.g. as shown at the right in Fig. 3a. The read head is hand-held, and comprises a bundle of optical fibres, leading to a photosensor matrix, and a number of light sources surrounding the bundle. When the head is correctly centred and oriented on a character the crossed array will be at the centre of the read head face, as shown at the left in Fig. 3a. Character reading takes place in two cycles. In the first cycle a crossed array is energized at an instant indicative of the position of the array on the guide surface and the infra-red radiation passes through the document and is sensed by the read head. The read head output passes via a store to a centring unit which determines the position and orientation of the cross within the field view by the head. If the cross lies within a certain distance from the axis of the head, as indicated by the innermost circle in Fig. 3a-3c, signals indicating the degree of off-centring and angular misorientation are generated. In the second cycle the read head senses light reflected from the document and passes signals representsing the character viewed to the centring uniwhich, dependent on the centring signals generated in the first cycle, generates correctly centred signals for use in a recognition unit. If the cross lies beyond the said certain distance signals may be generated telling the operator which way to move the head to centre the head on the character. The head may have a field of view which covers more than one character.

Abstract: 1,205,046. Recovery and purification of adiponitrile. ASAHI KASEI KOGYO K.K. 16 Nov., 1967 [16 Nov., 1966], No. 62219/67. Heading C2C. [Also in Division C7] In a process for recovering adiponitrile from an adiponitrile-containing reaction mixture obtained in the electrolytic dimerization of acrylonitrile using a catholyte which is kept in an emulsion state and which contains a supporting electrolyte, the emulsified catholyte (if desired after allowing it to settle out into two phases, i.e. an oil phase and an aqueous phase, removing a part of the aqueous phase thus separated therefrom, and recombining the oil phase and the remaining aqueous phase) is distilled in an acrylonitrile rectifying tower to remove a part of the acrylonitrile and water therefrom and the residue obtained is separated into two phases, i.e. an oil phase and an aqueous phase, and adiponitrile is recovered from the oil phase thus separated, the supporting electrolyte being capable of separating the concentrated residue obtained by distillation of catholyte into the two phases. The aqueous phase component separated from the residue in the acrylonitrile rectifying tower may be recycled to the catholyte tank, while the oil phase component comprising adiponitrile, water and a supporting electrolyte may firstly be extracted with water and/or a saturated solution of acrylonitrile and the adiponitrile subsequently recovered by charging said oil phase to a lower boiling component separator from the top of which a distillate comprising water, acrylonitrile and ethylene cyanohydrin is obtained and from the bottom of which is obtained a residue comprising adiponitrile and also, as impurities, biscyanoethyl ether and acrylonitrile oligomer, which residue is charged to an adiponitrile rectifying tower from the top of which purer adiponitrile is distilled and from the bottom of which is obtained a residue comprising adiponitrile, biscyanoethyl ether and acrylonitrile oligomer which is charged to an adiponitrile stripper, the vapour from the top of which is supplied to the lower boiling component separator, leaving a liquid residue of acrylonitrile oligomer, biscyanoethyl ether and supporting electrolyte which is withdrawn. As an alternative the whole of the distillate from the acrylonitrile rectifying tower may be supplied to a propionitrile separator in which propionitrile and water are left as a residue as acrylonitrile and water are distilled off, the acrylonitrile being recycled to the catholyte tank. The supporting electrolyte in the catholyte employed should be capable of separating the concentrated residue obtained by distillation of catholyte consisting of the oil and aqueous phases into two phases and may be, for example, a sulphate, halide, monomethyl sulphate or monoethyl sulphate which contains as cation a quaternary ammonium, ammonium or alkali metal ion. Other conventional additives may be present and a suitable flow diagram for the process is described.

Filed: 1971-11-10
Abstract: 1361038 Pressure casting machines IDRA-PRESSEN GmbH 10 Nov 1971 [26 Nov 1970] 52221/71 Heading B3F  In a method of pressure diecasting in which pressure is applied to the press piston 2 in three phases, the initiation of the intensified pressure applied to the press piston during the third phase is effected in dependence on the position of said press piston. The machine has a multiplier piston 5 movable in a cylinder 4, the chamber 7 formed in front of the piston 5 being connected to a pressure reservoir 8 via a valve 9. A second pressure reservoir 18 is connected to a chamber 16 which is opened or shut off in relation to the piston 5 by a valve having a closure piece 19. With a reversing valve 21 in the position shown, the pressures in the chambers 16, 32 and 33 are equal and the closure members 19 and 11 are maintained in their closed positions. After a first, slow movement of the press piston 2, the valve 21 is actuated by the press piston or by the rod 3 linking it to the injection piston. This causes the chamber 32 to be connected to a line 35 leading to a tank 34 so that atmospheric pressure now prevails in the chamber 32. This allows the member 19 to move to its open position thus causing the pressure in the reservoir 18 to be applied to the piston 5. An bydraulically operated time delay device 27 may be located in the line leading from the chamber 33 to the tank 35. The operation of this is initiated on the actuation of the reversing valve 21. After the valve 23 of said time delay device has moved from the position shown, the chamber 33 is open to atmospheric pressure and the valve 9 opens, thus allowing the fluid in the chamber 7 to pass to the reservoir 8 and the piston 5 to move to the left under the influence of the pressure of the fluid from the reservoir 18. This constitutes the third phase in the injection process and is arranged to take place after the mould has been filled with metal. The second phase begins on reversal of the valve 21 and is brought about by means not disclosed.
