Title: Improvements in or relating to heat treatment of materials by electricity
IPC: H05B6/04
Filed: 1925-07-23
Abstract: 258,049. Brown, W. J., and Metropolitan-Vickers Electrical Co., Ltd. July 23,1925. Induction furnaces.-Surface hardening and like heat treatment of bodies of electrically conducting materials is effected by placing the body 11 in a solenoid 12 through which is passed an alternating current of such frequency that heat is developed at the surface only of the body and then quenching the body before the interior thereof reaches an undesirably high temperature. A formula is given for a body in the form of a bright circular cylinder. The solenoid may be enclosed in a silica tube 25 heated by gas-jets 28 so as to raise the temperature of the lagged container 27 to the temperature to which it is desired to raise the surface of the pinion 11. When the latter is magnetic use may be made of its loss of this property at a high temperature to cause its release and immersion in the quenching bath 24. If desired the body may be quenched by jets projected through the convolutions of the solenoid while still being subjected to the electromagnetic field. The solenoid may be coupled to a valve 14 having an anode circuit supplied from a source 20 of high voltage current through a high frequency choke 21. The valve cathode is heated by means not shown. Condensers 13, 19, a blocking condenser 15, a grid leak 18, and a high frequency choke 16 electromagnetically coupled to an inductance 17 are arranged as shown.

Title: Radar system for measuring position and velocity of a distant object
IPC: G01S13/66
Filed: 1966-04-29
Abstract: 1,145,783. Radar. INTERNATIONAL STANDARD ELECTRIC CORP. 29 April, 1966 [30 April, 1965], No. 18857/66. Heading H4D. In a radar system for determining the position and velocity vector of an object, a main station measures that position utilizing signals re-transmitted from the object, two auxiliary tracking stations and the main station each measure a radial velocity component of the velocity vector, and the main and auxiliary stations are synchronized in frequency and phase by inter-communication means so that the measured velocity components can be compounded to give the velocity vector. The main station measures range and direction of a satellite; directional determination may be two-dimensional utilizing interferometry or a monopulse radar, and range measurement may utilize phase shift of modulation tones. Radial velocity component measurement utilizes Doppler frequency shift. In an embodiment the main station transmits to each auxiliary station a carrier modulated with a synchronizing signal S and a signal H for positioning the auxiliary station's tracking aerial, all the main station signals (including the carrier wave) being derived from a single oscillator, Fig. 3 (not shown); a further, C.W., signal is transmitted to the satellite. At an auxiliary station a phase-locked loop produces the synchronizing signal S<SP>1</SP> having a phase shift ## relative to that signal at the main station due to station separation; from signal S<SP>1</SP> there are derived four reference signals which control a second phase-locked loop for determining the Doppler frequency shift #f; the auxiliary station transmits to the main station a carrier modulated with a signal at (1 Mc/s. + #f), the signal S<SP>1</SP> and a telephony-communication signal H<SP>1</SP>, Fig. 4 (not shown). The synchronizing signals at the auxiliary stations are synchronized in frequency with the main station but have a phase shift: to bring the signals received at an auxiliary station into phase with those at the main station an inter-station phase-locked loop is established: the signal S<SP>1</SP> as received at the main station has a relative phase shift of 2## and. is processed in an arrangement, Fig. 5 (not shown) to yield a synchronizing signal with a phase shift of - ##: the synchronizing signal as received at the auxiliary station is thereby synchronized in frequency and phase with that at the main station. The modulations utilized are preferably frequency modulations.

Abstract: 1521814 Electronic timepieces TIMEX CORP 10 May 1976 [2 Sept 1975] 19199/76 Heading G3T [Also in Division G5] In an electrochromic display cell 8, e.g. in a figureof-eight array in an electronic timepiece, simultaneous fade-in and fade-out without the ambiguities of 'erase before write' and vice-versa is provided by a squarewave drive voltage Ï, alternating between two levels, supplied to a counter electrode 10 common to all segments, the segment electrodes of those to be written being connected to the opposite level only during the 'write' half cycle, while the segment electrodes of those to be erased are connected to the level opposite to the supply only during the 'erase' half-cycle. In their inactive half-cycles the segment electrode potentials float, leaving the 'write' electrodes at a mean negative voltage and the 'erase' electrodes at a mean positive voltage relative to the counter electrodes. The frequency is chosen so that only a fraction of the write or erase process takes place in one cycle, giving apparent smooth fade-in and fade-out. Each segment electrode is connected to the write (low) and erase (high) levels by switches 12, 14, closed by AND gates 16, 17 when the respective supply wave 0 or its inverse # is high and a command high signal is received on inputs 19, 21. In a timepiece circuit, Figs. 4, 5 (not shown), a decoder is provided for each segment of the arrays, driven by hours, minutes, month and date counters, providing logic signals to 'write' and 'erase' AND gates of those segments to be changed, via a flip-flop memory.

Abstract: 1417049 Rotary drum mixers H L MORGENSTERN 26 April 1973 19922/73 Heading B1F [Also in Divisions B7 and B8] In a method of transporting concrete ingredients to a job site and mixing it, the cement for a batch is transported separately in a trailer drawn behind the mixing truck and is pneumatically conveyed into contact with the other ingredients within the mixing drum using a low pressure air supply. The trailer may also convey the ingredients for one or more further batches. An apparatus comprises a mixing truck 1 towing a trailer 2 having hoppers 13, 14, 15 for cement, 16, 17 for aggregate, and tanks 18, 19, 20 for water, all except the tank 20 containing premeasured quantities. Water and aggregate for the initial batch are filled into the mixing drum at the batching plant; on arrival at the job site cement is added by a pneumatic conveyer 22, and distributed in the mix, by low-pressure air (7-10 p.s.i.) provided by an engine-exhaust blower 7. After the first batch is discharged the aggregate and water for a further batch may be supplied to the drum by a belt conveyer 35 and hose (53, Fig. 5 not shown). The low pressure air is also used to fluidize the cement hoppers and to provide top pressure to them and to the water tanks to assist discharge (see Fig. 3, not shown). High pressure air (100-110 p.s.i.) from the vehicle braking system is used to operate vibrators (30) associated with the cement and aggregate hoppers and actuate the various gates and valves (see Fig. 4, not shown). A hydraulic pump 5 supplies power to the belt-conveyer 35 and for raising and lowering the trailer draw-bar 10.
