Patent GB-673463-A (GB)
Abstract: 673,463. Electric control systems. PARFITT, F. P, Aug. 12, 1947. No. 22422/47. Class 40 (i). In a radio-controlled vehicle system, a control function on the vehicle is effected only on the simultaneous reception of two or more separable signals. In the system disclosed, for controlling the course and speed of a target launch, a single carrier wave is amplitude modulated by various signal frequencies, two modulation frequencies being used to effect each above mentioned control function in each sense: The starting of the vehicle may also be similarly controlled by two modulation frequencies and stopping controlled by sending a single frequency or by falling of the carrier strength to a predetermined value. Transmitter, The control unit, Fig. 4, which is described in Specification 673,465, comprises a starting switch 122, stopping switch 123, throttle "open" and "close" switches 120, 121, respectively, and a two-way switch 68 for altering the course of the vehicle to port or starboard. Operation of the stopping switch 123 connects earth from terminal 80 to a terminal 6 ; operation of any of the other switches connects this earth to a corresponding pair of the terminals 1 to 5, the connection being effected intermittently by a motor driven cam 64 in the case of course control. The earth markings on terminals 1-6 are extended over lines 112, 124 ... 128, Fig. 3, to operate respectively normally blocked oscillators 100, ... 105, tuned to different frequencies. The oscillator outputs are serially connected over line 119 to a conventional radio-transmitter, Fig. 2 (not shown), the radiated carrier being amplitude modulated by the signal frequencies from the one or more operative oscillators. Receiver. The modulation products are demodulated by a conventional superheterodyne receiver, Fig. 5 (not shown) and passed over line 170, Fig. 6 to serially connected circuits 171, ... 176 tuned respectively to the six modulation frequencies. The transmitted signal frequencies are separated and selected by these tuned circuits and operate the associated normally blocked valves to energize selectively, relays 184, 186 ... 190. A stopping signal energizes relay 184 to open contacts 185 whereby a relay, Fig. 7 (not shown) is deenergized to short-circuit the ignition circuits of the vehicle I.C. engines. Further contacts in series with the contacts 185 are arranged in the receiver to be opened by a relay and similarly stop the vehicle engines, should the received carrier strength fall below a predetermined value. The relays 186-190 each have two normally open contact pairs interconnected so that when any control signal other than stopping is initiated a circuit is completed over contacts of the operative pair of the relays 186 ... 190 to mark a contact 191, 2, 3 or 197, 8, 9 which effects the controls as disclosed in Specification 633 787, [Group XXXV], for starting, Specification 673,464, [Group XXXV], for course setting, and Specification 673,465 for throttle control.

Title: Accelerating and decelerating passengers in a transport system.
IPC: B66B29/08
Filed: 1978-12-19
Abstract: A horizontal conveyor 2 is driven at high speed. Alongside each of its ends are two horizontal conveyors 4 and 6. The conveyor 4 travels at low speed until boarded by a passenger e.g. through a revolving barrier 10 which is then automatically locked. The conveyor 4 accelerates so that the passenger can easily step onto conveyor 2 at X. Preferably the presence of the passenger on conveyor 2 is detected by sensor LS2 which causes the conveyor 4 to decelerate back to its low speed state and the barrier 10 to automatically unlock to allow another passenger access to conveyor 4. At Y the passenger transfers to conveyor 6 travelling at the high speed which conveyor 6 decelerates to low speed which allows the passenger to easily alight. The deceleration of the conveyor 6 is preferably initiated by the presence of a passenger on conveyor 6 detected by sensor LS4. Presence of the alighting passengers preferably detected by sensor LS5 causing the conveyor 6 to re-accelerate to high speed. <IMAGE>

Title: Stacking
IPC: B65G60/00
Filed: 1979-06-21
Abstract: A method of handling products consisting of producing or depositing products on boards 2, and then of stacking the boards supporting the products, is characterised in that boards are used which have feet 18 forming a projection in an upwards and/or downwards direction, which projection is at least equal to the height of the product above the board and in that the boards are stacked by superimposing them by means of said feet, in the form of a stack which can be handled by means of a fork-lift truck. With this method it is possible to produce, handle and store stacks of products without a separate support structure and without crushing the stacked products. Jacks 26 raise a loaded board to the bottom of a stack supported on pivoted stops 27. The boards and products are separately unloaded from the top of the stack. The products may be of concrete.

Patent GB-2041687-A (GB)
Title: Narrow beam scanning radar or lidar
IPC: G01S7/28
Filed: 1979-12-18
Abstract: In an object detection system in which pulsed electromagnetic radiation is transmitted in a narrow beam which is scanned, e.g. rotated, the scanning rate is made so fast, in relation to the aerial beam width and pulse repetition rate, that the beam dwell time is less than the period between successive radiated pulses. The pulse repetition rate, for pulses of the same frequency is not an integral multiple of the scanning frequency. Beam positions in successive scans and thus at non coincident azimuths, and the full 360 DEG  area is only covered after several scan periods, successive echoes from a target being likewise spaced by several scan periods. The invention is applicable to microwave radar systems or, to a pulsed laser system in which a narrow beam radiation from a laser 10 is scanned by a rotating scanner 11 at a scanning rate which is much higher than employed in conventional radar apparatus. This system enables the advantages to be obtained of the very narrow beam in giving good definition and minimising clutter but, because of the narrow beam and high scanning rate, imposes a maximum range for reception of signals reflected from the target or otherwise (e.g. jamming) locked to the transmitted pulses. <IMAGE>

Title: Warp-knit Lace Strip and Method of Manufacture
IPC: D04B21/10
Filed: 1980-02-18
Abstract: An entirely warp-knit lace strip having sinuate scallops knit of scallop- forming yarn, the scallops preferably having outwardly protruding U-shaped picots at their edges. The protruding parts are held or attached to soluble yarn portions. As desired, the soluble yarns 5 are dissolved to free the scallops and picots. Several portions of lace texture are made integrally from two kinds of yarn, an insoluble one and a soluble one, which are threaded on the same guide bar. The guide bar serves to knit the insoluble fabric portions I and the soluble portions II in an alternating arrangement along the direction of the needle bar. Simultaneously scallops B are formed on the edge of the insoluble fabric by means of another guide bar and protruding picots 6 are formed on these scallops. When adjacent insoluble fabric portions are connected by insoluble yarn, they are not separated on dissolution. This makes finishing processes, such as drying, easier. <IMAGE>
