Patent GB-506998-A (GB)
Abstract: 506,998. Discharge apparatus. STUMPF, F., and RING, F. Dec. 4, 1937, No. 33615. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 6, 1938.] Drawings to Specification. [Class 39 (i)] A leakage effect from the mutually insulated elements of a mosaic electrode is simulated electrically by supplying the elements with electrons from a cathode the potential of which is varied periodically according to a desired predetermined law through a range including a value such that no electrons reach any of the elements and a value such that all the elements receive electrons from all electronemitting parts of the cathode. It is shown that a saw-tooth law simulates an ohmic leakage resistance exactly, but sinusoidal or other laws may be followed. The mosaic may be scanned by a light ray. The frequency of variation of the cathode potential in a picture analyser is made greater than the picture point frequency, when this frequency acts as a carrier modulated by the picture signals. The output electrode may be rendered inoperative during the period when the elements are receiving electrons from the cathode, by reducing its potential below that of the mosaic ; the scanning ray also may be suppressed during this period. The output electrode may be replaced by a secondary-emission multiplier. The Specification as open to inspection under Sect. 91 describes also irradiating the mosaic with electrons of uniformly distributed velocity. This subject-matter does not appear in the Specification as accepted.

Patent GB-1094190-A (GB)
Title: Process for the production of condensed, mixed metal alcoholates
IPC: C07C31/32
Filed: 1964-12-23
Abstract: Condensed mixed metal alcoholates are obtained by hydrolysing a mixture of two or more alcoholates of different metals having the formula M(OR)x, where M is a metal of Group IIIb, IVb or IVa of the Periodic Table, including boron and silicon, R is a hydrocarbon radical and x is the valency of the metal M.  Mixtures consisting only of a titanium alcoholate and a silicon alcoholate are excluded. When the alcoholates have similar rates of hydrolysis they may be mixed and the water added; but when the rates of hydrolysis are different either the alcoholate with the lower hydrolysis rate is first partially hydrolysed before the alcoholate with the higher rate is added, or the hydrolysis is carried out in the presence of a catalyst comprising an alcoholate of a metal of Group IVa of the Periodic Table.  In examples, condensed, mixed metal alcoholates are obtained by hydrolysing aluminium s-butylate and tetraethyl silicate in the presence of isopropyl titanate, by hydrolysing tri-n-butyl borate and tetraethyl silicate in the presence of isopropyltitanate, and by hydrolysing tri-n-butyl borate and aluminium-s-butylate in the presence of isopropyl titanate.

Filed: 1973-11-13
Abstract: 1450918 Data processors CONTROL DATA CORP 13 Nov 1973 [8 March 1973] 52597/73 Heading G4A A plurality of addressable registers 50 are connected for information transfer with arithmetic and logic units 56, 57 and memory (over bus 99), the memory addressing unit, Fig. 3, including an object program address register 81, and incrementer 83, Fig. 2A, providing successive program addresses relative to a reference address (register 113, Fig. 3) and an exchange address register 103 and associated incrementer 127 providing successive alternative addresses representative of a program stored in memory outside the field of the object program. A comparator 87, Fig. 2A determines whether a program address supplied by register 81 is present in an instruction address stock 77 and, if it is, the corresponding instruction word is read from a stack 78 to an instruction register 91. The program address register 81 is loaded from an incrementer/decrementer 83 or from a branch address register 84 which in turn is loaded from an exchange address register 61, Fig. 2B or a selected general purpose register 50 used in performing operations specified by the instructions. Each instruction is divided into parcels by gates 92, 93 which are supplied to a translater 94 and program register 95 the latter receiving program codes K which, for example in jump instructions, may be added to program addresses via operand registers 64, 63 for loading the program address register 81 via a register 50 and branch address register 84. If the program address is not present in stack 77, a flag 100 is set to indicate addition of an object program reference address from an exchange parameter word register 61 to the program address to form an absolute address for a memory fetch operation to stack 78. A sequence of words may be transferred in this way by incrementing the address. A library call instruction causes a jump to a common program area available to a plurality of users in a multiprogrammed system, and in this case the program code K comprises an absolute memory address and initiates a memory fetch without further modification 20 bits of the address being transferred to register 81 as the new program address. An exchange instruction initiates a jump to a new program by adding the program code K to an exchange program address field of register 61, the new address causing the out of stack flag 100 to be set and a memory fetch operation to take place to obtain an exchange packet consisting of a new exchange parameter word destined for register 61 and 16 data words destined for different registers 50. The program address of the word in register 61 besides being "loaded in" register 81 is added to the reference address and the exchange address for the new program, also in the parameter word in register 61, to access memory at the new program area. An interlock register 40 enables transfer of data between processors in a multi-processor system without passage through memory.

Abstract: 1,241,030. Vigilance testing devices. BIVIATOR S.A. 12 Nov., 1968 [20 Nov., 1967; 11 Jan., 1968], No. 53505/68. Heading A5K. A device for testing a person's vigilance comprises a plurality of simultaneously and independently operable luminous indicators, at least two energy sources adapted to individually operate separate ones of the indicators at different luminosities or frequencies of variation of luminosity, thereby allowing comparison of two or more indicators whereof the luminosity of at least one indicator varies at a frequency within the person's flicker fusion threshold range, which frequency may be continuously adjustable within said range for said one indicator. A vehicle driver testing device comprises a row of seven luminous indicators 1 to 7, and associated interlocked test switches 1c to 7c which are interconnected with a commutator unit so that, when a test switch 10 is closed, one indicator is chosen in a random manner to flicker and the others are connected to a d.c. supply. If the driver has sufficient vigilance he will pick out the flickering indicator and may press the handle operable switch from the set 1b to 7b, associated one with each indicator, associated with the flickering indicator to complete the ignition circuit of the vehicle to enable it to be started. At the end of a relatively short time switch 10 is automatically opened to break the ignition circuit unless the appropriate switch 1b to 7b has been previously operated to complete the circuit and supply current to a holding coil 12 of a shorting switch 11 for switch 10. A second vehicle driver testing device, Fig. 2 (not shown) comprises a luminous indicator (22) driven by a generator (26), preset to a certain frequency, and a second luminous indicator (23) alongside the first driven by a generator (28) having a scale (25) attached to a potentiometer for adjusting its frequency. To start the vehicle an ignition switch (42) is first closed and if the driver has the required level of vigilance he may adjust the frequency of flickering of the second indicator (23) to match that of first indicator (22). The frequencies are compared by a comparator (29) which when they are equal actuates interlocking circuitry which enables the car to be started if the driver has a level of vigilance such that he is able to join a movable contact (40) to a fixed (39), and hence complete a circuit, by passing the movable contact (40) vertically between two contact bars (41) without touching either of them with contact (40). The interlocking circuitry also prevents starting of the car if the frequencies of the indicators are not first matched before the contacts (39) and (40) are joined in the manner described above.

Abstract: 1,196,336. Thermal storage apparatus. HCH. BERTRAMS A.G. 27 Nov., 1967 [7 Dec., 1966; 24 June, 1967], No. 53763/67. Heading F4U. Heat is transferred from heat storage apparatus employing an eutectic mixture of salts as the storage medium to water flowing in a heating system via an intermediate heat transfer fluid. As shown, the eutectic 2 fills a container 1 provided with vertical tubes 3 extending between lower and upper compartments 4, 5. Before the eutectic is heated by electric heating elements 10, the tubes 3 and compartments 4, 5 are filled with water so that during heating steam is generated and water is forced out of compartment 4 through pipe 7 into an expansion vessel. Water in a central heating system is circulated through a coil 6 in compartment 5 and steam is condensed on the coil, the condensate being collected in compartment 4. Container 1 may be surrounded by, and spaced from, a casing, the gap between the casing and container communicating with the upper and lower compartments (Fig. 3, not shown). The gap may alternatively replace the tubes 3 and a plurality of eutectic containers may be assembled to form a battery (Figs. 4 to 6, not shown). In a further embodiment (Fig. 7, not shown), the steam generated in the casing surrounding the eutectic container is circulated through an external heat exchanger, the rate of circulation being valve-controlled in accordance with the requirements of the central heating system.

Abstract: 1409085 Data transmission: synchronizing LICENTIA PATENT VERWALTUNGS GmbH 22 Nov 1972 [22 Nov 1971] 54019/72 Heading H4P In a two-stage coding system for correcting transmission errors, i.e. (1) additions/deletions resulting in incorrect block size and (2) phase displacement, a first (interval) code is arranged to indicate, on reception, errors where binary characters are added/deleted from blocks, also correct phase displacement, with a second (external) code arranged to correct sync. errors using the indication provided by the first code. The codes may be formed by polynomial operation, e.g. Bose-Chaudhuri on the information characters to which redundant sync. patterns are added.  At the transmitter, 2l+1 binary characters from a sync. pattern generator SG, are fed through switches S1, S3 to line and through mod 2 adder A2 into coder C1 back coupled through switch S2.  Subsequently with switch S2 in position 2 information characters k<SP>1</SP> = k-(2l+1) from source Q are passed into coder C2 also back coupled through mod 2 adder A1 performing the operation g(x) = 1+x<SP>k1</SP>, into coder C1, and to line. With S3 in position 2 and source Q and coder C1 stopped, 2 redundancy characters are emitted to line. This completes the first coding operation.  Source Q is then restarted and information passed to line and into coder C2 which on termination of the information issues the redundancy code to line through switch S1 position 3, this completing the second coding operation. At the receiver, Fig. 3, incoming code words are received into shift register P1 and unit K which eliminates any errors introduced in transmission. Unit B corrects sync. phase errors in words free from transmission errors by the use of the cyclically overlapping sync. pattern. When phase errors have been corrected information characters are passed into store P3, also to shift register P4 back coupled through mod 2 adder P4 and switch S position 1 which "calculates" the error syndrome pattern. For the previous second code word an "address" has been already placed in store P2 which causes switch S to be reversed to position 2 at a time determined by sync. phase error hence the pattern is superimposed through mod 2 adder A2 with the content of P3 before issue to a receiving device.
