Title: Improvements in or relating to aerials and aerial systems for use in wireless telegraphy and telephony
IPC: H01Q21/10
Filed: 1926-10-08
Abstract: 285,106. Franklin, C. S., and Marconi's Wireless Telegraph Co., Ltd. Oct. 8. 1926. Addition to 242,342. Aerials.-In an aerial electrically long in comparison with the signal wave-length, the radiation from alternate half wave-length sections is arranged to be substantially less than the radiation from the intervening sections. As shown the section B comprises a non-radiating section B and tail portions T1B, and T2B so proportioned that the effective radiation of this section, and similarly the section D, is approximately only 30 per cent of that from the plain oscillating sections A, C, E. This improves the radiating efficiency of the aerial as a whole, particularly in respect of the sections such as A more remote from the feeder R. A number of such aerials may be grouped, and inductively coupled, or connected together in pairs as described in Specification 263,943.

Title: Improvements in or relating to automatic pilots
IPC: G05D1/04
Filed: 1944-12-15
Abstract: 662,832. Automatic craft control systems. BENDIX AVIATION CORPORATION. Dec. 15, 1944 [Dec. 31, 1943], No. 25240/44. Class 38 (iv). In an automatic pilot for a craft a control surface, responsive to signals from a direction or attitude reference device upon deviation of the craft from a predetermined direction or attitude, is also automatically responsive to variable signals produced independently of the firstmentioned signals by the operation of a control device to change the direction or attitude of the craft independently of the reference device. In the arrangement described the rudder 12 of a craft is automatically controlled in response to signals transmitted electrically from a gyro-stabilized earth inductor compass 10 and a rate-of-turn gyro 13, and the ailerons 19 and elevators 20 are automatically controlled in response to signals transmitted electrically from pick-offs 15 and 16 respectively, associated with perpendicular axes of an artificial horizon gyro 14. The system is of the type described in Specifications 662,831 and 662,833, with the addition of the following manual controls: (a) a pitch trim knob 247  adjusting the position of the stator of the inductive receiver of signals from the pitch pick-off of the artificial horizon gyro to preset the pitch attitude of the craft; (b) a bank trim knob 219 adjusting the position of the stator of the inductive receiver of signals from the bank pick-off of the artificial horizon gyro to preset the bank attitude of the craft; (c) a turn knob 230 simultaneously adjusting the position of the rotor of the inductive receiver of signals from the bank pick-off of the artificial horizon gyro and, through slotted lever 224. the position of the rotor of the inductive receiver of signals from the rate-of-turn gyro to preset a banked turn. Operation of this knob in either direction from a neutral position to effect a turn in either direction also results in (i) movement, through cam 225 and lever 226, of the rotor of the inductive receiver of signals from the pitch pick-off of the artificial horizon gyro to give the necessary " up-elevator " to prevent tendency of the craft to dive during turn, and (ii) the opening of a switch 233 to de-energize a magnetic clutch 65 so that the rudder no longer responds to signals from the earth inductor compass. After the required turn has been made, however, manual return of the knob to the neutral position recloses the above-mentioned switch so that the craft is maintained on its new course; (d) an airspeed compensator knob 243 adjusting the pivot point of lever 224 to alter the ratio of adjustment of the bank and rate-of-turn receiver rotors referred to at (c) above to give a banked turn suited to the speed of the craft. The assembly of the above controls on a common panel is described.
Patent GB-255047-A (GB)
Abstract: 255,047. Suida, H. July 13, 1925, [Convention date]. Acetic acid.-In the preparation of concentrated from dilute acetic acid by heating a mixture of crude acetic acid and water with an extractive medium of high boiling point, e.g. cresol, a solvent of low boiling point insoluble in water and containing chlorine, e.g. trichlorethylene, is added to the extractive medium. Dilute acid superheated with steam in a column E is treated with a mixture of one part of trichlorethylene and two parts of cresol from a tank 1. The evolved vapours are led off through a pipe 6 and sprayed with cooling water from a dephlegmator D in a column Z filled with rings &c., the temperature being adjusted so that no cresol passes off through the pipe 9, but only trichlorethylene vapours mixed with a little water which are condensed in a condenser K<1> and flow from a pipe 10 and sprayer 15 into a washing column W. The condensate from the column 2 is further cooled in a condenser K<2> and then flows into a separator S, where the lighter water separates from the heavier cresol and trichlorethylene mixture and is removed through a tap 13 and pipe 16 to the bottom of the column W, the triohlorethylene and cresol being returned to the still E through pipes 14, 4 and a funnel 3. The descending trichlorethylene in the washer W is washed by the ascending water, and pure water flows off through a pipe 18 while purified trichlorethylene flows to a tank R, where it is pumped back to the tank 1. Specifications 230,447 and 255,043 are referred to.

Title: Improvements in deflecting output circuits for cathode ray tubes
IPC: H03K4/28
Filed: 1939-09-18
Abstract: 534,705. Valve generating circuits. THORNTON, A. A. (Philco Radio & Television Corporation). Sept. 18, 1939, No. 26059. [Class 40 (v)] Relates to circuits for producing saw-tooth currents in inductive loads 3 having distributed capacity 17 in which the load circuit oscillates at its natural frequency and is impulsed by energy from a valve 4 to which voltage pulses 6 are applied. In order to improve the linearity of the current in the inductive load, a second circuit, e.g. valve 8, is in series with the load 3 and the effective resistance of this circuit is controlled by connecting the screen grid of valve 4 to the control grid of valve 8 through a circuit 10, 11, 12. The wave-form of the voltage 6 applied to the grid of valve 4 is such that energy flows into transformer 3 only during the latter portion of each scanning cycle when the voltage 6 exceeds the cut-off level g of the tube, the negative peaks h ensuring the cut-off of the valve 4 when the load 3, 17 is oscillating freely. The inverted triode 8, following this cut-off period during which the current in the load circuit is reversed, controls the dissipation in its own internal resistance of the energy stored in the coil during the time the valve 4 is conducting.

Abstract: 953,184. Magnetic storage apparatus. SIEMENS & HALSKE A.G. July 27, 1960 [July 27, 1959], No. 26114/60. Heading H3B. The self-inductance of the wires of a magnetic core matrix is reduced by placing a non-magnetic conductive plate adjacent the wires. As shown in Fig. 1, the cores M of the matrix are mounted on a copper plate P1 and between posts K1 projecting from the plate. A copper cover-plate P2 rests on top of the posts K1 and the surrounding insulating wire terminal strips R. To increase the proximity of the wires with the plate P1 studs K2 may be raised from the plate between each set of four cores as shown in Fig. 3. The top plate P2 may be adjustable to vary its spacing from the wires and may also carry studs corresponding to the studs K2. Matching inpedances may be connected between the ends of each wire and the conductive plates. Instead of using pre-formed conductive plates it is said that metal may be cast about the wires and between the cores provided none of the cores is completely linked with cast metal. The plates P1 and P2 may be of non-conductive material coated with a conductive layer.

Title: High-speed function generator
IPC: G06F1/035
Filed: 1973-06-01
Abstract: 1423281 Sine/cosine generators SINGER CO 1 June 1973 [2 June 1972] 26288/73 Headings G4H and G4A In a sine-cosine generator, a memory holding sine values is addressed via a complementing circuit. As disclosed the memory is read-only and has two parts to store digital imformation about the sines of angles between 0 and 90 degrees, each angle A modulo 90 degrees being represented as B + C where C is much less than B, and the identity: sin (B+C) = sin B cos C + cos B sin C, is approximated as: sin (B + C) = sin B+cosB<SP>1</SP> sin C, three hexadecimal digits specifying A apart from the quadrant information, the least significant representing C, the three with the last replaced by zero representing B, and B<SP>1</SP> being the three with the last two replaced by zero. The first memory part stores the values of sin B (slightly reduced to facilitate complementing-see below). The second memory part stores the values of cos B<SP>1</SP> sin C. The three hexadecimal digits pass through a complementer consisting of an inverter and adder (for adding one) where the binary number formed by the three (binary-coded) hexadecimal digits is complemented or not depending on whether sine or cosine is required and on the quadrant of the input information. Addition of one in the complementing is inhibited if the hexadecimal digits are all zero, to avoid error in evaluating sin 90 degrees, sin 270 degrees, cos 0 degrees and cos 180 degrees. Of the three digits emerging from the complementer, the two most significant address the first memory part and the most significant and least significant address the second memory part. The least significant output bit from the first part disables the second part if equal to one to delete the second term of the above equation for angles from 87À87 to 90 degrees. The rest of the output from the first part and the output from the second part are added in a second adder. An inverter follows the adder to permit complementing if the output is negative and is required in complemented form (a control signal allows the latter to be specified). If complementing is not required, the reduction referred to in the stored values of sin B is compensated by adding one in the second adder and inversion is not performed. If complementing is required, compensation is omitted but inversion is performed. A sign bit is appended to the output, depending on quadrant and whether sine or cosine was ordered.
