Title: Improvements in or relating to electrical information storage equipment
Inventor: RIDLER DESMOND SYDNEY
IPC: H04J3/00
Filed: 1952-08-13
Abstract: 728,154. Digital electric calculating apparatus. STANDARD TELEPHONES & CABLES, Ltd. Aug. 13, 1952, No. 20351/52. Class 106 (1). An electric information storage circuit comprises a chain of single core magnetic storage devices, each device forming one stage of the circuit and settable to a first or second stable magnetic state to form an information pattern, means for applying stepping pulses to all the devices in common, whereby all those in the first state are changed to the second state, interconnections between each pair of consecutive devices over which an output pulse passes when the first device of a pair changes from the first to the second state, the pulse setting the second device to its first state, and means controlled by a stepping pulse for ensuring that an output pulse is unable to affect the second device of a pair before the stepping pulse ends, whereby each stepping pulse moves the pattern of stored information one stage along the chain. The windings Wd enable the initial setting up of a pattern of information in the magnetic cores T1 ... T4. Upon the application of a positive stepping pulse + P to all the windings Wb, those cores found in the " 1 " (the " first ") state are changed to the " 0 " (" second ") state, the change of flux in each core causing an output pulse to develop in winding We. No change and no output pulse occurs in cores already in the " 0 " state. Output pulses developed in windings Wc pass respective rectifiers U2, U4, &c. and charge condensers C1, C2, &c. Rectifiers U3, U5, &c. are blocked as long as the stepping pulse +P lasts, maintaining the charges until, at the termination of the pulse +P, those condensers C1, C2 &c. which have been charged drive current through windings Wa to change the conditions of succeeding cores to the " 1 " state. Thus the pattern of information steps along from left to right, and may be entered into and read out of the storage circuit in this manner. Specification 663,574, [Group XXXIX], is referred to.

Title: An improved method of heat casting refractory blocks
IPC: B28B1/54
Filed: 1947-07-31
Abstract: 629,710. Casting refractory blocks. ELECTROREFRACTAIRE. July 31, 1947, No. 20822. Convention date, May 22, 1940. [Class 87 (ii)] A method of making solid cast refractory blocks comprises pouring molten refractory material into a mould 1 e.g. of sand provided with a gate through a font mould 2 of a volume insufficient to prevent pipe formation, removing the font mould after a rigid wall or shell 3 has formed inside the latter due to solidification, breaking away this shell when all the molten material has drained away from it into the casting, protecting the gate with a heat conserving cover 11 e.g. of firebrick, during a substantial part of the solidification which produces a pipe 6, and thereafter removing the cover and filling the pipe with additional molten material. After removal of the font shell 3 together with the top sand slab 1a irregular refractory protuberances and adhering'sand may be scraped away from the rim of the gate. The top of the casting is then covered with insulating powder 5 and the cover 11 placed in position. As fast as the septa 6a form in the pipe 6 they are broken away by momentarily removing the cover 11 and poking with a bar. The font mould is then replaced during refilling of the pipe. The casting is finally annealed. To prevent insulating powder 5 from falling into the casting when the cover 11 is removed, the gate of the casting may be surmounted by a ring (not shown) serving as a retaining wall for the powder. The cover 11 is placed over the ring. Specification 298,983, [Class 87 (ii)], is referred to.

Title: Improvements in organic compounds containing silicon
IPC: C07F7/18
Filed: 1952-08-20
Abstract: Organosilicon condensation products are formed by heating an aliphatic dihydric alcohol with vinyl-trichlorosilane, the mol. ratio of alcoholic hydroxyl groups to chlorine atoms in the reactants being greater than 1:1.  It is preferred that the mol. ratio does not exceed 2:1.  The product is a free flowing liquid when the mol. ratio is greater than 1.3:1, and is an ungelled material soluble in organic solvents when the mol. ratio is between 1:1 and 1.3:1.  In the latter case the reaction may be carried out in a solvent having a boiling point above 100 DEG C., e.g. toluene, xylene or a hydrocarbon which boils above 200 DEG C.  The reaction is exothermic but is heated to complete the reaction, e.g. at 200 DEG C.  The hydrogen chloride formed during the reaction should be removed as a gas or neutralized by the addition of a hydrogen chloride acceptor, e.g. an alkaline earth metal carbonate.  The aliphatic dihydric alcohol may be a glycol such as ethylene glycol, propylene glycol, trimethylene glycol or a butylene glycol, or a polyglycol such as diethylene, triethylene or dipropylene glycol.  In examples 1 to 4, vinyltrichlorosilane is heated with propylene glycol, diethylene glycol and 2-ethylhexanediol-1.  In example 5, propylene glycol is heated with vinyltrichlorosilane in xylene.ALSO:The invention comprises the product formed by heating an aliphatic dihydric alcohol with vinyltrichlorosilane, the mol. ratio of alcoholic hydroxyl groups to chlorine atoms in the reactants being greater than 1 : 1.  It is preferred that the mol. ratio does not exceed 2 : 1.  The product is a free flowing liquid when the mol. ratio is greater than 1.3 : 1, and is an ungelled material soluble in organic solvents when the mol. ratio is between 1 : 1 and 1.3 : 1.  In the latter case the reaction may be carried out in a solvent having a boiling point above 100 DEG C., e.g. toluene, xylene or a hydrocarbon which boils above 200 DEG C. The reaction is exothermic but is heated to complete the reaction, e.g. at 200 DEG  C.  The hydrogen chloride formed during the reaction should be removed as a gas or neutralized by the addition of a hydrogen chloride acceptor, e.g. an alkaline earth metal carbonate. The aliphatic dihydric alcohol may be a glycol such as ethylene glycol, propylene glycol, trimethylene glycol or a butylene glycol, or a polyglycol such as diethylene, triethylene or dipropylene glycol.  In the examples, vinyltrichlorosilane is reacted with each of diethylene and propylene glycol and 2-ethylhexanediol-1,3.

Title: Selective filtering system for electric pulse trains
IPC: H04N5/08
Filed: 1945-08-17
Abstract: 597,323. Pulse discriminating and demodulating- circuits. STANDARD TELEPHONES & CABLES, Ltd. Aug. 17, 1945, No. 21107. Convention date, May 24, 1943. [Class 40 (v)] Undesired pulses are eliminated from a pulse train by passing the train through two or more filtering devices, each adapted to assist in eliminating pulses whose shape differs from the desired pulse in one of a number of different characteristics. A pulse train, Fig. 3 (a), comprising desired pulses 10 and undesired pulses 11 ... 14, is fed to a clipping amplifier 16, Fig. 2, to clip the train at the level 17 to eliminate small amplitude pulses 11. The output, Fig. 3 (b), is applied to a positively biassed amplifier 22, only large amplitude pulses 12 being effective in producing an output pulse 12a, Fig. 3 (c), which is fed to one grid of a mixing valve 30, the output from the clipper 16 also being fed to the other grid so that the pulse 12 is eliminated in the output, Fig. 3 (d). In order to remove pulses 14 having differently sloped edges but the same base width, a slice is taken between levels 111, 112 by feeding a double diode 100 so biassed that the anode 103 is cut off between pulses while anode 108 passes current. The resulting waveform is fed to valve 42, the fall in potential across resistor R appearing as in Fig. 3 (e), the pulse 14 having the width 115, 116 if the signal has been passed through the slicing valve 100. The pulses cause the tuned circuit L, C to ring, the valve 46 damping the circuit when valve 42 ceases to conduct so that waveform, Fig. 3 (f), is fed to the clipper valve 60. By adjusting the bias on valve 60 clipping is performed at the level 92, a pulse 80a being fed out from the circuit. This may be clipped further at level 86a, curve g and differentiated to give pulses 80b, 80c curve h. By adjusting the tuned circuit L, C to a period equal to twice the pulse width 115, 116 of the sliced pulse 14, an output pulse corresponding to pulse 14 may be produced, curves (i) and (j) (not shown).
