Title: Telemetering system
IPC: G01S13/76
Filed: 1945-05-18
Abstract: 603,440. Telemetering systems. STANDARD TELEPHONES & CABLES, Ltd. May 18, 1945, No. 12649. Convention date, June 12, 1944. [Class 40 (i)] Meter readings on a moving vehicle, e.g. an aeroplane, and the distance between the vehicle and a fixed station are indicated by means of radio frequency impulses. Pulses from a pulse generator 3 are transmitted at a constant rate from a fixed station 1 to a moving vehicle 2 where some are reflected back to the station by a reflector 11 and others are received by an antenna 10, passed through a variable delay 13 controlled in accordance with the reading of a meter 16, and then retransmitted to the station 1. The reflected and retransmitted pulses are received on antenna 9 and applied to the Y-plates 24 of a cathode-ray oscillograph, thereby producing indications 26, 27 respectively on the screen. A sweep potential is applied to the X-plates by the pulse generator 3 via a sweep generator 22. The spacing between the pulses 26, 27, is proportional to the meter reading and the distance between the pulse 26 and the origin of the sweep line 25 is proportional to the distance between the stations 1, 2. When only meter readings are to be indicated the reflector 11 is not required as the time between the generated pulses is made so great that the pulse 26 coincides with the origin of the sweep line 25. When transmitters 4, 14 operate at different frequencies the station receiver 8 is tuned to the same frequency-as transmitter 14 ; another receiver having to be provided when the distance between the stations is to be measured. In a modification, Fig. 3 (not shown) the oscillograph is replaced by a meter of the cross-coil phase type, Fig. 4 (not shown). In another modification, Fig. 5 (not shown), the reflected and retransmitted pulses respectively " make " and " break the circuit of a power meter connected to a supply so that the meter reading is an indication of the time between the pulses and, therefore, of the reading of the meter 16. When short-pulse delays are required, the delay device 13 consists of an adjustable passive delay network ; for longer delays an adjustable trigger circuit is used, and for very long delays an acoustic device, Fig. 6 (not shown), is used.

Title: A process for the production of cottonseed oil based coating compositions
IPC: C09F7/00
Filed: 1957-04-23
Abstract: Varnish based on cottonseed oil is obtained by cooking cottonseed oil with rosin and metallic oxides, preferably a mixture of calcium oxide, zinc oxide, lead monoxide and manganese dioxide, until the resulting varnish acquires the viscosity desired, suitably 300 c.s. The lead monoxide is preferably present to the extent of 0.5-1.25 per cent of the oil by weight and the manganese dioxide to the extent of 0.33-0.76 per cent, cobalt acetate also being present if desired.  A preferred embodiment comprises adding 10 per cent of the oil to the molten rosin at 200 DEG  C., heating the mass to 240-270 DEG  C., adding the oxides followed by the bulk of the oil, and then cooking the resulting mixture at 310 DEG  C.  In a modification which results in a better-quality product, the acidity of the rosin is reduced by esterification with glycerol,this esterification being suitably performed at 270-280 DEG  C. after the addition of calcium and zinc oxides, but before addition of other oxides.  After the varnish has reached the desired viscosity it may be cooled to 200 DEG  C. and thinned with turpentine or white spirit.

Patent GB-131831-A (GB)
IPC: D03D45/20
Abstract: 131,831. Leumann, F. Feb. 18, 1919. Shuttles, changing bobbins in, automatically. -- In looms having a number of shuttles and mechanism including a weft feeler for replacing an exhausted bobbin with another of the same colour from a stationary magazine having as many bobbin compartments as there are boxes in the change shuttle-box, the feeler closes a circuit including a relay associated with the appropriate magazine compartment and adapted to ctose another circuit, which, at the proper time, operates through a magnet a lever device arranged to allow a bobbin of the desired colour to drop by gravitation into position under a transferrer. The change-box is operated by hooks 15<1>, Fig. V, controlled by rods 13' and cards 14. A rod 13<1> pushed in by a card acts on a rod a<1>, a mushroom head of which acts on and is engaged by a pivoted bar q so as to hold displaced a lever p<1>, which connects contacts x<1>, y<1> until the rod a' is freed by the advance of another rod on a change of shuttle taking place. The feeler z, Fig. VII, closes one of, say, four circuits when a bobbin is exhausted according to the shuttle in use, each circuit including the electric source M, feeler z, and metal plate on the bobbin, lever and contacts such as p<1>, x<1>, y<1>, and a magnet such as m<1>. The core o, Fig. 1, of the energized magnet m is drawn down and its rod k frees a cone i on a rod u, which is displaced as shown by a spring r so that an arm n thereon touches a contact d in another circuit, including a contact 16, which is closed at the proper time by an eccentric and lever mechanism, the lay having meanwhile moved back, opening the formerly closed circuit at the feeler z before an oscillating lever c becomes operative. When the exhausted shuttle returns to the fixed box at the replenishing side of the loom either at the next or a subsequent pick, the lever such as p<1> again connects the contacts x<1>, y<1> and, the contact 16 becoming closed at the proper time, the circuit through the parts 16, n<1>, d<1>, x<1>, p<1>, y<1> and the corresponding magnet m is closed and the rod k is depressed and acts through a lever c to raise a hooked lever h, which is caught and moved by the lever c, then in the proper position. Movement of the lever h turns a lever w to depress a lever l against a spring f. Supports 5, 24 on the pivot pin of the lever l are moved away from underneath the lowest bobbin 2 in the vertical magazine compartment A, A<1>, and a lever 25 loose on the pivot pin is freed to be moved by a spring 6 against the next bobbin 1, the lowest bobbin 2 being released to drop under a transferrer while the other bobbins are held up. A nose n<5> on the lever w acts on a lever n<6>, s to restore the rod u to its original position with the cone i engaged by a rod k, and extra movement of this rod causes the arm n to act on a lever n<7> to close contacts 26, 27 and energize a magnet, which causes a lever on the transferrer to be engaged by a nose on the lay to operate the transferrer, the bobbin 2 being pushed past spring fingers g<1>, g<2> into the shuttle N.

Patent GB-809186-A (GB)
Title: A process of preparing unsaturated aromatic halogen compounds
IPC: C07C17/00
Filed: 1957-04-26
Abstract: Omega-halostyrene, homologues thereof and halo indenes are prepared by pyrolysis of the boric ester of the corresponding halohydrin, preferably in vacuo.  The boric esters may be prepared by known methods, e.g. by heating the halohydrin with boric acid or boron oxides.  Preferably a catalytic amount of a suitable inhibitor such as hydroquinone is added.  The molar ratio of halohydrin to boric acid should preferably be a little less than 1 : 1.  Either crude or pure halohydrins may be used as the starting material.  Any impurities present may be removed during the formation of the boric esters and before pyrolysis if required. The process of the invention may be carried out by introducing boric acid together with the halohydrin into a normal vacuum distillation equipment and heating the mixture slowly in vacuo while distilling off the water formed. The heating is continued until the halostyrene or haloindene distills off.  Temperatures for the pyrolysis above 150 DEG  C., and a vacuum of 15 to 18 tons give favourable results.  Suitable compounds to which the method may be applied are those in which an aromatic system is connected to a chain of at least two carbon atoms of which the former carries an hydroxyl group and the latter a halogen atom. Examples are given of the preparation of omega bromostyrene from styrene bromohydrin and boric acid, 4-methyl-omega-bromostyrene from 4-methylstyrene bromohydrin and boric acid, 2-bromo-indene from indene bromohydrin and boric acid, omega bromostyrene from styrene bromohydrin and boron trioxide, and omega-chlorostyrene from styrene chlorohydrin and boric acid.  All the examples are carried out in the presence of hydroquinone.  Specifications 746,042 and 746,043 are referred to.

Abstract: 1498743 Radar TOKYO SHIBAURA ELECTRIC CO Ltd 1 April 1975 [1 April 1974 28 Oct 1974] 13339/75 Heading H4D The Specification describes a compact microwave transmitting and receiving device for use in, e.g. a doppler intruder detector, comprising a rectangular waveguide having one end closed by a short-circuiting plate, and, disposed within the waveguide an oscillating diode and a mixer diode each at a distance of half the waveguide wavelength or a multiple thereof from the short circuiting plate. In a first embodiment, Figs. 1 and 2, rectangular waveguide 11 has end 12 closed and end 13 open to act as a radiating aperture with flange 14 for attachment to an antenna (not shown). The transmitter, a Gunn diode 15 is mounted off axis with respect to the central axis joining the top and bottom walls of the waveguide within the waveguide between a post 18 insulated from the top wall by sheet 17 and a stationary screw 19 mounted in the bottom wall. Receiver mixerdiode 16 is similarly mounted displaced from the centre axis an equal distance as Gunn diode 15. Tuning screws 23 and 24 are mounted in the top wall a distance l 2 , equal to a quarter waveguide wave length, on either side of the TX and RX diodes. Operating voltage Vg for a Gunn diode 15 is supplied through lead 25 and conductive post 18, while the mixed down signal from diode 16 which receives direct radiation from Gunn diode 15 and relected energy from a moving target is supplied along line 26 to a filter 27 which is tuned to a doppler frequency for use in, e.g. an automatic door, a burglary alarm device or a car-collision preventing device. The mixer diode is positioned at a distance from the Gunn diode so that its sensitivity is maximized. In a second embodiment, (Fig. 4, not shown), the Gunn diode is disposed actually on the centre axis. In a third embodiment, Fig. 5, the Gunn transmitting diode 34 is mounted as in Fig. 1, but the mixer diode 35 is mounted fixedly between brass post 39; which extends from the top waveguide wall into hollow cylindrical coaxial line holder 40, fixed by screw engagement into the bottom wall of waveguide 30; and the short-circuited closed end wall 41 of the coaxial line holder 40. The length of the coaxial line body is calculated from certain given formulae, and it is stated that better matching of the mixer diode is obtained than with the Fig. 1 embodiment. In Fig. 10 (not shown) the arrangement of Fig. 5 is modified in that the Gunn diode is mounted on the central axis, and the mixer diode (35) may be mounted at a position intermediate the ends of post (39).
