Title: An improved apparatus for indicating variations in moisture content in a fabric
IPC: G01N27/04
Filed: 1946-10-01
Abstract: 621,516. Determining moisture-content of materials. FIELDEN, J. E. Oct. 1, 1946, No. 29199. [Class 37] Apparatus for determining the distribution of moisture across the width of an impregnated fabric consists of two pairs of electrodes d and e placed one electrode on each side of the fabric near the opposite edges. The resistances between the electrodes of each pair are compared with two equal resistances band c by means of a Wheatstone bridge arrangement, the output of which is amplified by two valves i and g. The anodes of the valves are connected together, and the cathodes are joined through a variable potentiometer k, a meter m being connected directly between the cathodes. Any difference in moisture content at the edges produces a difference in resistance between the pairs of electrodes, and is shown by a reading of the meter, indicating which side has the larger moisture content. Facilities are provided for an initial balance of the bridge. Specification 619,534 is referred to.

Title: Organosilicon compositions
Inventor: HARVEY JOHN HOWARD DEREK
IPC: C07F7/02
Filed: 1964-07-17
Abstract: An organosilicon composition is prepared by hydrolysing a mixture of by-product chlorosilicon compounds, obtained by reaction of an alkyl chloride (e.g. methyl chloride) with silicon. HCl formed is removed either by physical separation or by neutralization with Ca(OH)2. The product may be recovered as a solid or if mixed with Ca(OH)2 suspension may be recovered as a slurry or paste.  An excess of Ca(OH)2 over that required to neutralize the HCl may be used.  The products are used to impart water repellant properties to masonry, cement or plaster and also in forming pelletized fertilizers, pesticides and herbicides and are incorporated prior to the hardening stage.ALSO:The water repellant properties of a hardened solid composition are improved by incorporating therein, prior to the hardening step, an organosilicon composition obtained by hydrolysing a mixture of by-product silicon compounds obtained from the reaction of an alkyl chloride and Si to produce alkyl chlorosilanes, removing the aqueous acid either by physical separation or neutralization with Ca(OH)2 and recovering the product either as a solid or slurry.  The compositions may be included in, e.g. 0.4-2% of the dry ingredients in building materials such as cement and plaster.  They may also be used in pelletized fertilizers to control their rate of degradation and release to the soil.

Title: Electric fire alarm and circuit fault control system
IPC: G08B29/04
Filed: 1954-10-14
Abstract: 765,491. Electric fire alarms. EKMAN, O. I. H. Oct. 14, 1954, No. 29602/54. Class 118(1). A fire alarm and fault control system comprises a two-wire loop circuit a and b having sections I, II ... X, each of which sections is provided with double-throw thermo switches T, and units SI which include a normally closed double-pole switch S which may be opened manually to give alarm. The switches S are each shunted by a resistance CI and a metal rectifier RT which in normal circuit conditions blocks current flow from b to a. Relays Ra, Rb provided in series with wires a and b deenergize upon a break in a or b respectively, and may be closed manually or electrically and have additional sets of contacts (not shown) to give circuit condition signals. The resistance of relay Ra in wire a is greater than that of the resistance R in wire b so that the potential of wire b at any one section point is normally greater than that of wire a at a corresponding point. A fire signal is given only when a and b are simultaneously broken, and when this occurs both relays operate to change over the switches 12a, 12b, 13a, 13b and connect the ends of the wires a, b at each end to duplicated bridges W (only one shown). The wire b which is now connected via lines 15, 19 to the negative battery terminal is at a lower potential than the wire a so that the rectifiers RT become conductive and permit the resistance CI to be balanced by the rheostatic or selection switches SS in the bridges W. When balance is attained the relay 18 drops out and signals the number of the broken section. Relays 16, 17 give fault signals in the event of the bridge W being deenergized. If wires a and b are short-circuited then current passes from the positive terminal of the battery through holding relay Ra and resistance R in parallel and back along the wire a to the negative terminal of the battery, thus shorting out relay Rb since its positive supply via resistance R now travels through wire a to the negative of the battery.

Filed: 1971-06-24
Abstract: 1394431 Data processing systems PLESSEY CO Ltd 16 June 1972 [24 June 1971] 29670/71 Heading G4A [Also in Division H4] Data transfer between a plurality of processors CPU, memory modules SM and peripheral units PD-PP is via data paths PBAPBC unique to the individual processors, and each memory module SM and peripheral unit incorporates an individual access unit SA1- SA3, PAD-PAP which includes an address recognition means responsive to an address defining the associated storage module or peripheral unit, the peripheral access units also including a plurality of addressable registers which are accessible, from a processor by supplying on that processors' data path an address having a first field defining the peripheral unit and a second field defining one of the registers. The registers may store control information, and status information relating to the peripheral unit and data to be transferred to and from the peripheral unit. Also included in the system shown are a plurality of microprogrammed channel modules CUX, CUY having individual data parts CBX, CBY and multiplexers MPXM, MPXN linking the data paths PBA-PBC and CBX, CBY to peripheral data lines PDM, PDN. Address recognition means are also included in the multiplexers and the access units CAX, CAY of the channel modules, the latter providing access to command, status and data registers in the modules. Each processor CPU can thus directly address any storage location or any command, status or data register of any channel module or peripheral unit and any channel module may directly address any storage location or any peripheral command, status or data register. Thus no special I/O instructions are required since data transfer can be performed using simple memory read and write instructions executed by a processor or a channel module. Direct communication between a processor and a channel module allows the setting up of I/O block transfers which are performed word by word by the channel module independently of the initiating processor. The provision of the multiplexers allows addition of processors and storage modules to the system without the need for a variable number of ports on each peripheral access unit. Each storage module access unit has provision for queue-sorting access demands on a three-level priority basis, equal level demands being resolved on a first-come, first served basis. The multiplexers have a similar demand queue-sorting arrangement.

Title: Electric vehicle speed control systems

Filed: 1975-07-16
Abstract: 1519853 Control of D.C. motors LINDE AG 16 July 1975 [16 July 1974] 29734/75 Heading H2J In a speed control for an electrically propelled vehicle, a diaphragm arranged in the light path to a photo-transducer is arranged to be moved from a central rest position in opposite directions for forward and reverse motion, means also being provided to inhibit drive current when the diaphragm is passing through its central rest position. In Fig. 2, a luminescence diode 13 and a photo-resistor 14 are mounted in a block 10 having a slot 12 in which is movable a diaphragm 6 secured to a shaft 5, the latter being rotatable by the speed control pedal (2) of an electric vehicle coupled to shaft 5 by a lever (3) and pivot member (4), Fig. 1 (not shown). The resistor 14 forms part of an impedance transformer including resistors r4, r5 and transistor T2 and controlling a transistor T1, whose output voltage at 17, 18 is used to vary the speed of the vehicle driving motor (preferably D.C.) through a conventional pulse control unit for a semiconductor switch controlling the supply (preferably from a battery) to the motor. The portion of the diaphragm 6 in the slot 12 includes an aperture (7), Fig. 1 (not shown), whereby movement of the control pedal varies the amount of light reaching photoresistor 14 and hence the speed of the motor. Shaft 5 also carries cam members 8, 9 actuating a reversing switch for the motor, the diaphragm 6 being movable from a central rest position to provide speed control in either direction of rotation. To prevent current surges when the motor is reversed, caused by the change in photo-resistor 14 lagging the change in diaphragm movement to produce an incorrect transformer output voltage at the central position of the pedal, the reversing switch includes contacts 19, 20 which open at the central position to switch off transistor T2, the output voltage controlling T1 then being determined by resistors r4, r6 chosen to ensure that the motor current is zero at the central position. The diaphragm may be designed to vary the change of light over its path of movement, so that the corresponding speed change is non- uniform to provide greater control sensitivity at low speeds. Similarly light changes for the same movement may be different for opposite directions of diaphragm movement to provide a lower speed range for reverse movement of the vehicle. Alternatively, the light changes may be chosen to provide the same speed ranges. The resistor 14 may be replaced by a photocell, the diaphragm may be completely black or expose the light in its central position and the various electrical components may be constructed as a printed circuit. The motor current may be controlled by contactors instead of a semiconductor switch.
