Title: Remote control for a car by laser beam
IPC: G05D1/02
Filed: 1974-02-01
Abstract: 1448623 Automatic control of position or course CONSTRUCTIONS MILLS-K 1 Feb 1974 [12 Feb 1973] 04721/74 Headings G3N and G3 R In the remote control of an automotive vehicle, particularly a trolley for picking-up and depositing pallets bearing loads at any desired point in a warehouse storage area, a plurality of laser emitters and receivers are used to remotely guide the vehicle along selected paths and to transmit data to the vehicle, e.g. stop, start, forward, reverse, turn left, turn right &c. As shown Fig. 8 the laser emitters are located along two adjacent sides of the store area and define a grid. The receivers are located on at least two complementary faces of the vehicle. Alternatively the laser emitters may be on the vehicle and the receivers may be stationary. Guiding the vehicle along a desired trajectory requires a receiver having at least three photo-diode detectors, on the vehicle. As shown Fig. 1, when the vehicle is on a desired path the laser beam strikes a detector C. If it deviates to the left such that the beam strikes a detector D the latter sends a signal to a unit Pd whereby an electric motor causes the vehicle wheels to pivot through a predetermined angle # thus steering the vehicle back on to the desired path. The amount of pivotting movement is stored in a memory Md. When the detector C again intercepts the laser beam the output therefrom is applied to an AND gate together with that from the memory Md so that the AND gate will transmit a signal to unit P'd causing the wheels to pivot back through the angle # in the opposite direction, and cancelling the memory. With more than one detector on each side of C, the further from C of a detector which intercept the laser beam the greater the number of angular steps of the wheel pivotting motors to return the vehicle to its proper trajectory. The operating instructions data may be transmitted by pulsing the respective laser beams in a coded manner, e.g. by periodic interruption of the beam by means of a perforated disc (D) driven by a variable speed motor (M) as illustrated in Fig. 4 (not shown). Each laser emitter simultaneously provides for steering and control data transmission and is connected to a computer in whose memory co-ordinates of loads already deposited in a warehouse area are stored and which controls the trolley movement to deliver a load at a proper destination or to pick-up a load. The computer may be connected to peripheral equipment which visualizes the movements and fixed positions.

Abstract: 446,850. Starting; reversing. CROSSLEY, SIR K. I., and CARTER, H. D., c /o Crossley Bros., Ltd., Openshaw, Manchester. Feb. 14, 1935, No. 4749. [Class 7 (v)] To reverse a multicylinder compressionignition oil engine, compressed air is supplied to the engine cylinders by a distributing valve comprising a rotary ported sleeve g having one or more pairs of angularly and axially spaced ports h, i, j, k, &c., one port of each pair admitting compressed air to pipes a .. d leading to the engine cylinders for forward and reverse starting respectively. Reversal is effected by moving the sleeve g axially by means of a lever x, bringing ports i, k, &c. into register with the pipes a.. d instead of ports h, j, &c. The sleeve g is driven through skew gearing t, u and is connected by splines z to a shaft f carrying fuel-pump cams v, so that axial movement of the sleeve is accompanied by angular movement of the sleeve and of the cams v to adjust the phase of the starting-air admission and the fuel injection. The starting air is admitted to the interior of the sleeve g from a pipe q and a groove r through a port s in the sleeve. Each pair of ports h, i, &c. may co-operate with a number of casing ports arranged around the sleeve in order to reduce the length of the device. Specification 399,265 is referred to.

Abstract: A polymer of the general formula <FORM:0925722/IV(a)/1> wherein R1 and R2 are alkyl, cycloalkyl, aryl, aralkyl or alkaryl; R3 is R1 or <FORM:0925722/IV(a)/2> or <FORM:0925722/IV(a)/3> or the three dimensional polymeric network obtainable on hydrolysis of <FORM:0925722/IV(a)/4> or SiX4 wherein X is halo or alkoxy; R4 is R1 or H; R5 and R6 are H or <FORM:0925722/IV(a)/5> Z is a divalent hydrocarbon radical having from 1-10 C atoms; q is 0 or 1; Y is sulphur or oxygen when P is pentavalent and is absent when P is trivalent; and m and n are integers, may be made by effecting addition of a phosphorus compound of the formula <FORM:0925722/IV(a)/6> across the double bond of an unsaturated silane of the formula <FORM:0925722/IV(a)/7> , hydrolysing the Si-bonded hydrolysable radicals by means of an aqueous medium and condensing the resulting Si-OH groups by heating.  The addition reaction is described and claimed in Specification 925,721 and may be effected at temperatures between 0 DEG  and 200 DEG C., in the absence or presence of catalysts or U.V. radiation, and in the absence or presence of inert organic solvents.  The hydrolysis can be conducted at 25 DEG C., or together with condensation at 120 DEG  to 200 DEG C., with dilute mineral acid, e.g. HCl, or aqueous alkaline compounds, e.g. alkali metal hydroxides or bicarbonates, ammonia and dimethylformamide.  The polymers may be end-blocked in known manner with triorganosilyl groups.  Products containing trivalent P may be converted into products containing pentavalent P by treatment with sulphur or mild oxidizing agents.  In a typical example (1) diethylphosphine was mixed with divinyldichlorosilane and irradiated with U.V. light to yield, after vacuum distillation, a viscous oil which, on hydrolysis and condensation, gave a clear, viscous oil; this product could be oxidized with H2O2 or be reacted with S to yield the corresponding polyphosphineoxide- or polyphosphinesulphide-polysiloxane.  Uses: As water-repellents, hydraulic fluids antifoaming agents, insecticides, germicides, pesticides, antioxidants, flame retarders, plasticizers, vulcanization accelerators, dielectric materials and as lubricants for rubber and plastics.

Abstract: 1460465 Roller test stand ROBERT BOSCH GmbH 5 Feb 1974 [6 Feb 1973] 5202/74 Heading G1N A roller test stand for motor vehicles comprises; an electrical machine 4 e.g. an eddy current brake, for driving or braking at least one roller 3 of the stand; a control circuit for controlling the roller speed by way of the machine, the circuit having a potentiometer 9 and lever 10 for determining the desired value for the speed and a correction element in the form of a potentiometer 17 of which the tapping 16 is adjusted by lever 5 as a function of the reaction torque arising during operation of the machine. The correction is necessary because the controller 8 has proportional-plus-differential action so a permanent control deviation will occur. To correct this a lower desired speed value has to be simulated by the correction element. Thus if an undesired increase in roller speed occurs due to increase in brake horsepower from the vehicle wheel 1 the tapping 16 is adjusted by lever 5 due to torque reaction of the machine. As a result a corrective voltage of inverse polarity to that from 9, 10 is supplied to the inverting input of the amplifier 19. So a lower desired speed value is simulated and the actual speed is controlled back to the true desired value. The torque reaction produced when machine 4 brakes the roller acts on a pressure cell 6 via the lever 5 which cell is connected to an indicator 7.

Title: Improvement in radio-pulse-echo systems
IPC: G01S13/02
Filed: 1944-03-20
Abstract: 594,525. Radar. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. March 20, 1944, No. 5209. Convention date, Jan. 23, 1943. [Class 40 (v)] Groups of pulses trom a radar sender 10, Fig. 1, are emitted in succession from four directive aerials U, R, D, L in beams whose directions are slightly up, right, down and left respectively with respect to the mean axis of the beams, and the pulses received on the same aerials take charge in succession of the A.V.C. of the I.F. amplifier and also of motors 71, 72, which effect automatic following in elevation and traverse respectively. The pulse frequency may be 4 kc./s. and the wiper 12 which distributes the pulses from the sender 10 to the aerials U, R, D, L may make 60 revolutions per second. When the aerial system is out of alignment, the echoes received on the four aerials will differ in strength, and in order that fluctuation may not ensue in the range indications in the range apparatus 30, volume-control voltages are stored on separate. condensers C1... C4 and applied to a part 27 of the I.F. amplifier through cam switches such as 42, 43, which are synchronized with the wiper 12. The receiver may be protected against the outgoing pulse and against clutter from near objects by pulses from a circuit 57 which periodically reduces the gain and is provided through the circuit 56 with a gate pulse which desensitizes the receiver except in the neighbourhood of the time of arrival of an echo. Automatic following in elevation is effected by a motor 71 and in traverse by a motor 72, the control potentials being derived from the A.V.C. condensers C1, C3 and C2, C4 respectively and applied through cam switches 63, 64 and 66, 67 and through amplifiers 61 and 62. The voltage applied to each motor, so long as the aerial system is out of alignment, comprises an alternating component whose phase is reversed as the aerial system passes through alignment and the motors, which are of the A.C. type with synchronous field, reverse their direction of rotation in response to reversal of phase. The motor-control cam switches such as 63 may or may not be isochronous with the A.V.C. cams such as 42; in the latter case they may retain their switching frequency when the aerial switching frequency is changed for purposes of security.
