Title: Improvements relating to automatic electric current generating apparatus
IPC: H02P9/00
Filed: 1930-11-04
Abstract: 364,238. Self-contained supply systems. CHANCE BROS. & CO., Ltd. and SPAINK, J. H. ABBINK-, Lighthouse Works, West Smethwick, Staffordshire. Nov. 4, 1930, No. 33119. [Class 38 (iv).] Starting prime movers.-Relates to automatic current generating apparatus in which a prime mover coupled to a generator and starting motor has means responsive to the load to start and stop the engine, and comprises the combination of a generator consisting of a pair of parts, one of which serves as an engine starting motor and supplies current to a low voltage battery which is permanently connected to the distributing circuit, whilst the two generator parts operate jointly for supplying current to the distributing circuit, and means responsive to a current flowing in the distributing circuit for connecting the two parts of the generator to the said circuit and the low voltage part to the battery. When a consuming device e is connected to the line a current flows from the battery s through the relays a, b, c, one of which closes a switch a<1>, b<1> or c<1>, to connect a relay r across the battery. This relay closes switches r<1>, r<2>. Closure of switch r<2> completes the circuit of a relay k, switches k<1>, k<2> close and connect the machine d<2> to the battery s. This runs as a motor to start the prime mover. When the voltage of the generator d<1> reaches normal value a relay v opens a switch v<1> to break the circuit through the relay k. Switches k<1>, k<2> open and connect the machines d<1>, d<2> in series so that the two machines together form a compound generator to supply the load. If the engine does not start after a given time a thermal relay h will open a switch h<1> to disconnect the machine d<2> from the battery. This switch can only be closed by hand. When the consuming devices are switched off the current through the coils a, b, c falls to zero, the circuit through relay r is broken and the switches r<1>, r<2> open and the apparatus shuts down. Specification 147,663, [Class 38 (iv), Electric supply and transmission systems &c.], is referred to.

Title: Improvements in and relating to vacuum filling machines
Inventor: HUSBAND ERNEST
IPC: B65B1/16
Filed: 1963-08-21
Abstract: 978,769. Valves. RECKITT & SONS Ltd. Aug. 21, 1963, No. 33189/63. Heading F2V. [Also in Division B8] A vacuum filling machine comprises a rotating foundation member which carries a number of vertically reciprocable platforms- 1 and incorporates a reduced pressure reservoir 2, and a rotating hopper 4 with a number of filling heads 5, a filling head being directly above each platform 1 and each filling head having a supply valve which may be as described in Specification 978,768. Each supply valve is connected by a conduit 6 to a diaphragm valve 7 which is in turn connected by a conduit 8 and a bore 9 to a surface port in a valve chest 10 which rotates with the reservoir 2. As the foundation member rotates the bore 9 comes into contact with a port 15 of a stationary valve part 13 and is thereby connected to a conduit 16 in which a more highly reduced pressure than in the reservoir 2 prevails. This causes the valve 7 to open the conduit 6 to the reservoir 2 to exhaust air from the filling head and actuate the supply valve. The filling operation is terminated when a bore 12 comes into contact with a bore 14 in the stationary valve part 13 causing air to enter a conduit 11. This admission of air may also serve to remove surplus powder from the head. Finally the diaphragm valve is re-set when bore 9 comes into contact with a bore 27 and the platform 1, which during this time has been in its raised position, is then lowered.

Title: Improvements in electron discharge tube amplifiers
IPC: H03F1/36
Filed: 1937-12-01
Abstract: 506,652. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd., BARNARD, R. M., and ROCHE, A. H. Dec. 1, 1937, No. 33202. [Class 40 (v)] In a negative feedback amplifier the feedback path is constituted by a transmission line of predetermined characteristic impedance and having a length not exceeding the wavelength of the maximum frequency handled or by a short-length of coaxial cable transmission line. The Figure shows an amplifier with feedback from a resistance R1 in the cathode of the output stage to a resistance R2 in the cathode circuit of the input stage. In a modification a bridge arrangement of the feedback path is used for both the input and output. The length of the line may be comparable to the wavelength used or may be a small fraction of the wavelength corresponding to the highest frequency at which the product of the gain and the feedback exceeds unity and the terminating resistances of the line may differ from its characteristic impedance. By varying the length of the line between one half and a whole wavelength corresponding to the frequency at which instability is liable to occur the frequency discrimination of the amplifier may be controlled. Specification 374,130 is referred to.

Title: Improvements in and relating to hybrid analogue-digital computing equipment
Inventor: SMITH KENNETH LESLIE
IPC: G06J1/00
Filed: 1962-08-29
Abstract: 1,022,683. Electric analogue calculating. IBM UNITED KINGDOM HOLDINGS Ltd. Aug. 19, 1963 [Aug. 29, 1962], No. 33205/62. Heading G4G. Hybrid computing equipment for performing arithmetical operations in a sequence of stages using operators in digital form and operands in analogue form, includes analogue storage means to store the partial results of the arithmetical operations derived from the successive stages in the sequence for a period long enough to permit the modification of the digital operator controlling the next stage in the sequence, thereby holding the analogue partial result of one stage for a period before it is supplied as an operand to the next stage in the operation. Fig. 3 shows the basic unit of the equipment which comprises a digital register 10 of binary or decimal form controlling an impedance network 11. The network 11 multiplies the digital input D by the signal V r  supplied to terminal 13 to provide one input to a high gain amplifier 12. The other input to amplifier 12 is an analogue signal at terminal 16, and the output of the amplifier may either be the difference of the two inputs or the sum of the two inputs with reversed polarity (Fig. 4, not shown) according to the nature of the amplifier. With terminal 16 earthed (Fig. 5, not shown), the circuit operates either as a multiplier, with a second input supplied to terminal 13, or as a digital to analogue converter, with a reference signal supplied to terminal 13. With terminal 15 connected to terminal 13 (Fig. 6, not shown) to give negative feedback, the circuit divides the input applied at terminal 16 by the digital input D. In Fig. 7 the output of the amplifier 12 is fed to a comparator 17 which is also supplied with a reference signal. The comparator adjusts the digital register 10 until its inputs are equal, and the register 10 then indicates the digital equivalent of the analogue input at terminal 16. The basic circuit is combined with an analogue store, a main digital store, and gating circuits (Fig. 8, not shown) and may be programmed to perform arithmetical calculations. An example is given of a programme for calculating (P+p) C(1+at), (Fig. 9, not shown). An example is also given of a programme for calculating the square root of P using the iteration Y n+1 =0À5 (Y n +P/Y), Fig. 10 (not shown).

Title: Improvements in the manufacture and production of alkylene derivatives from alkylene oxides
IPC: C08G65/28
Filed: 1929-11-11
Abstract: <PICT:0342022/IV/1> Hydroxyalkyl compounds are prepared in the absence of a catalyst by leading a mixture of an alkylene oxide with water or an organic hydroxyl or carboxyl compound e.g. an alcohol, phenol, or carboxylic acid, continously through a reaction tower, which may be enamelled, where it is immediately heated to a high temperature usually above 130 DEG  C., the product being freed from unchanged materials, preferably in a continuous manner.  It is also preferred to use the hydroxyl or carboxyl compound in excess. Only small amounts of alkylene oxide are brought into reaction at any one time.  After separation from the product, the unchanged portion of the component used in excess may be used again.  The process is usually carried out at pressures between 5 and 30 or more atmospheres.  The heat of reaction may be used for p  preheating fresh initial material or for the separation of the products.  In the apparatus shown, a pump 1 forces the reacting materials through a heat exchanger 4, whence the mixture passes by a pipe 10 to a pressure-tight cylindrical reaction vessel 7, which contains a heating coil 6, 61 and is provided with thermometric devices 8, 81. The mixture is then passed via the pipe 5 to the heating coil of the heat-exchanger and is withdrawn for separation of the product through the pipe 9.  In the examples (1) a mixture of one molecular proportion of ethylene oxide and 2 of ethyl alcohol is heated to 180 DEG  C., a pressure of 30 atmospheres being attained.  The product, ethylene glycol monoethyl ether, is freed from excess of ethyl alcohol by distillation.  (2) Propylene glycol monomethyl ether (CH3-O-CH2-CHOH-CH3) is obtained from 1,2 propylene oxide and methanol.  (3) Ethylene glycol is obtained from ethylene oxide and water.  (4) Ethylene glycol monoacetate is obtained from ethylene oxide and glacial acetic acid.  The reaction tower used is enamelled. (5) Ethylene glycol monophenyl ether is obtained from ethylene glycol and phenol.  (6) The methyl ether of o -chloropropylene glycol is obtained from methanol and epichlorhydrin.
