Title: Improvements relating to data processing systems

Filed: 1964-12-07
Abstract: 1,027,423. Electric digital data-storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 7, 1964 [Dec. 24, 1963], No. 49622/64. Heading G4C. Data is transferred into and out of a memory under direct control of address decoders associated with the memory. For input, the 80 columns of a punched card are sensed concurrently to produce signals which are ordered and grouped by a control panel, and then passed to a transistor and AND-gate input matrix (Fig. 5, not shown) controlled by the address decoders which serializes the signals from the 80 columns at the position (along the column) currently being sensed. These serialized signals are fed to a coder (Fig. 6, not shown) in which cams produce a binary-coded indication of the said position, to cause this to be stored (via a buffer register) in input locations of the (core) memory corresponding to columns with holes at that position. Output from an output region of the memory to a punch is similar, being via the buffer register, a decoder, matrix and control panel.

Title: System for damping the oscillations of a grab
IPC: E02F3/96
Filed: 1964-12-07
Abstract: 1,021,969. Grab excavators. SOC. NOUVELLE DES ATELIERS DE VENISSIEUX Dec. 7, 1964 [Dec. 5, 1963], No. 49706/64. Heading E1F. In a grab excavator, obtained by replacing the shovel of a shovel excavator with a grab, oscillations of the grab about the pivotal connection between it and the vertically swingable boom of the excavator are damped out by a boom-mounted piston cylinder unit associated with a throttling device for limiting between the end chambers of the unit passage of hydraulic fluid in response to movements of the unit's piston which is mechanically coupled to the grab. When arranged for shovel excavating operations the throttling device is disassociated from the unit to the ends of which pressurised hydraulic fluid is then arranged to be supplied as required to allow the unit which is mechanically connected to the shovel to pivot the shovel relative to the boom structure.

Abstract: 1,073,560. Semi-conductor devices. GENERAL ELECTRIC CO. Nov. 30, 1965 [Dec. 28, 1964], No. 50698/65. Heading H1K. The surface breakdown voltage of a junction (15) is increased by surrounding an enclosed region (16) with a surface region (17) of the same conductivity type but having a lower conductivity, Fig. 1 (not shown). The lower conductivity surface region may be surrounded by a further region (26) of even lower conductivity, Fig. 2 (not shown). The surface region may extend to the periphery of the wafer, Fig. 3 (not shown), and the major portion may be etched away to leave a mesa structure. Fig. 4 (not shown). In a mesa-type diode the surface region may extend over the etched surface, Fig. 5 (not shown). The extent of the surface region may be limited by a heavily doped "stopper" region (43) of the same conductivity type as the main part of the wafer, Fig. 6 (not shown), and this "stopper" region may extend over the sides and lower face of the wafer, Fig. 7 (not shown). A transistor may be produced by diffusing an emitter region into the enclosed region, Fig. 8 (not shown), or both emitter and collector regions may be formed integrally with a surface region which extends over the whole of the surface of the wafer and separating them by means of a heavily doped stopper region which also provides access to the base region, Fig. 9 (not shown). One or more of the regions of an SCR may be surrounded by a surface region and the emitter junction may be partially short-circuited, Fig. 10 (not shown), and the edge of the wafer may be bevelled, Fig. 11 (not shown). The enclosed surface regions may be formed by masking the surface of the wafer with a layer of silicon dioxide and diffusing-in the impurity through a window to form the highly doped enclosed region and simultaneously diffusing-in the impurity through the bulk of the oxide to form the lightly doped surface region. The semi-conductor material may be silicon or germanium and the impurities may be a phosphorus, boron, or gallium. In all the embodiments at least part of the oxide mask is left on the device to provide a passivation layer.

Abstract: 1432866 Asymmetric membranes GENERAL ELECTRIC CO 2 Nov 1973 [18 Dec 1972] 51112/73 Heading B5B A membrane having a porosity increasing from adjacent one major surface of the membrane to the second major surface comprises as the polymeric material polyarylene oxide, polycarbonate, polyvinyl acetate polyalkyl methacrylate, polysulphone and polymers of monovinyl aromatic hydrocarbons, the membrane containing a 1-25% of grafted elastomeric material as particles of size range 0À1-10 microns distributed therein, the elastomeric material being in a state insoluble in the polymer material and the grafting material being soluble in the polymer material. The porosity is due to the presence of branch like network of pores extending through a mass of polymer crystals interconnected in a rigid network. The membrane is prepared as in Specification 1,295,585 with the exception that the grafted elastomeric material is added to the casting solution. The liquid coating solution is applied via the head 11 to the moving belt 12 as a layer 5-25 mils. thick. The belt transports the layer 23 horizontally for a period equal to the desolvation time then transports the layer a leaching bath 24, the roller 14 being two spaced rollers that engage the edges only of the belt not covered with the coating. The wet solidified layer at some point is separated from the belt via the roller 26 and the unsupported swollen layer is conducted over rollers 27 and 28 through a long path so that the solvent content of the solidified layer is reduced to a low level and the internal stresses have been relaxed. The layer 23 is removed via roller 29 to dryers (not shown) and the belt 12 is reconditioned by transport via rollers 17 and 18 through a washing in a tank 31 and a dryer (e.g. belt drying rollers 32, 33) before return to the coating drum 22. The belt is any flexible surface and the washing liquid in tank 31 is water.

The initial whole cell harvest may be stored before use, after freezing, freeze drying, or being killed with thimerosal.ALSO:Antigenic material, for use in preparation of vaccine for B pertussis, is extracted from isolated B. pertussis cell wall material by treatment with a solution of sufficient deoxycholic acid salt to give a final concentration of 0.1 to 10% wt./vol., at 2 to 5 DEG C. and alkaline pH of a cell wall suspension equivalent to 100 to 2000 bacteria/ml.  The cells may be grown on conventional media, and ruptured mechanically, (see Division C6), and are then washed free from cellular material, extracted as above, the deoxycholate removed by, e.g. dialysis ion exchange, or ultra-filtration, and the solution used to prepare vaccines. These may be mono- or polyvalent, the latter containing toxoids such as Tetanus or Diptheria toxoid, or may be adsorbed onto adjuvants such as aluminium hydroxide or phosphate, or precipitated with alum.  The vaccines may contain preservatives such as thimerosal, benzethonium chloride, benzyl alcohol, or g -picolonium chloride.
