Inventor: BERRIE ALISTAIR HOWARD
IPC: C09B35/031
Filed: 1968-12-09

Title: Automatic tuning circuit
IPC: H03J7/26
Filed: 1972-12-18
Abstract: 1376387 Touch responsive switching systems SABA SCHWARZWALDER APPARATE -BAU-ANSTALT AUGUST SCHWER SOHNE GmbH 18 Dec 1972 [17 Dec 1971] 58281/72 Heading G1N [Also in Division H3]  In an automatic tuning circuit for a receiver in which capacitance diodes are used for tuning and the tuning voltage UT is obtained by charging and discharging a capacitor 15 via two constant current means 13, 14, the charging and discharging action by means of a respective bi-stable 9, 10 is automatically interrupted on reaching a received signal 27 and the existing charge is retained by a fine tuning voltage 28, and tuning is effected by touching an electrode 1, 2. Touching an electrode 1, 2 suppresses an oscillator 3, 4 such that brief touching initiates automatic tuning by producing an impulse through a capacitor 7, 8 to set an associated bi-stable 9, 10 whereas a longer period of touching the electrode causes a time constant circuit 17, 18 to be switched in after a predetermined delay to se the associated bi-stable 9, 10 and cause continuous tuning which is interrupted after releasing touching the electrode by a reset impulse to the bi-stable derived from a received signal 27. To avoid accidentally initiating continuous tuning operation due to successively touching the electrode 1, 2 a capacitor 23, 24 is discharged in the intervals between touching the electrode via a diode 21, 22 and a transistor 5, 6. The bi-stable 9 or 10 set by a brief or a larger touching of the electrode 1 or 2 causes the capacitor 15 to charge or discharge via current source 14 or current drain 13 until a received signal is obtained at 27 to reset the bi-stable 9 or 10. The tuning voltage UT is then maintained by the fine tuning voltage obtained at 28 via the FET 16. When the electrode 1 or 2 is touched for the longer period the suppression of oscillation at 3 or 4 turns off the transistor 5 or 6, after 1-5 seconds capacitor 23, 24 has charged sufficiently and the circuit 17 or 18 operates to set the bi-stable 9 and 10 to provide continuous tuning. The diodes 25 and 26 are provided to reset the bi-stables 9, 10 when the tuning voltage UT reaches an upper or lower limit.

As shown, the junctions 14 defining the resistive regions 6 are shorted by the common portion 4 of the emitter terminal within aperture 16 to prevent transistor action. Figs. 3 and 4 (not shown) illustrate an embodiment of copending Specification 1,278,442, and depict two double emitter transistors forming part of an integrated circuit. The resistors associated with the four fingers are defined by paths in a common diffused region; in accordance with an embodiment of the present invention, the individual resistors may instead be formed by replacing the common region by individual diffused regions within a common body part of the opposite conductivity type. In the various structures unbalance in the various emitter connections which would be occasioned by relative differences in path length from the respective resistor to the point of attachment of the external emitter lead on the common electrode portion may be allowed for in manufacture by making the common electrode portion of continuously varying width or by making the impurity concentration and/or diffusion depth of the resistance regions different or by providing different path lengths in the various resistance regions or by varying the areas of contact to the respective regions.

Filed: 1968-12-16
Abstract: 1,212,060. Control circuits for welding apparaus. ELCO CORP. 16 Dec., 1968, No. 59779/68. Heading H2H. [Also in Division H3] Wedding control circuit comprises a device for passing a welding current through a metallic junction only when the impedance across the welding electrodes is below a predetermined value. The circuit is used in conjunction with apparatus for welding together two conductors initially separated by thermoplastic insulation; The electrodes are heated and apply pressure to the conductors to soften the insulation and squeeze it out from the area to be welded, and welding occurs only when electrical contact has been made between the conductors. In the arrangement shown in Fig. 2, the control circuit 14, which comprises a signal generator 22 and an amplifier 23, holds open contacts 16 in the welding supply circuit by means of a relay 24 during the period of heating and removing the insulation 19. When electrical contact is made through the electrodes 13, the signal generator 22 is shunted and the resulting, output from the amplifier is insufficient to keep the relay 24 energized. Hence, the contacts 16 close and power from a source 12 flows through the transformer 11 to the electrodes 13 to make the weld. Circuits for the signal generator and amplifier, including thermionic values, are described with reference to Fig. 3 (not shown).

Abstract: 1284594 Attaching sutures to needles DEKNATEL Inc 16 Dec 1969 [25 Aug 1969] 61353/69 Heading A5R [Also in Divisions B3 and Dl] A method of attaching a suture to a needle comprises forming a needle point 17 at one end of a length of initially soft wire, forming a generally V-sectioned channel 11 in the side of the needle, partially closing the channel, for example to a U-sectioned shape, by bending the walls towards one another, hardening the needle, and forcing the walls 12, 13 closer together to hold one end of a suture located in the channel. The preclosing of the channel is preferably performed in a die comprising two members having opposed semi-cylindrical recesses therein within which the walls 12, 13 are bent towards each other. The subsequent closing of the walls 12, 13 onto the suture is preferably accomplished without annealing the needle, or after only one annealing stage for very hard needles. Nibs (15), Fig. 2 (not shown) may be formed in the channel 11 to grip the suture.

Abstract: A bolster-type shearing machine is provided with two coacting knives (43,44) for cutting off the stock. One bolster (41) is driven for providing shearing movements of the machine, the other (42) being stationary during these movements. Both knife-carrying bolsters (41,42) are made displaceably guided in each other and each of them carries, adjacent its associated knife (43,44), a support (45,46) for the stock.

Title: Assessing where ball strikes ground in tennis
IPC: G01V8/20
Filed: 1978-11-10
Abstract: A device to assist the assessment of where the ball strikes the ground in tennis which uses a wide light ray or a plurality of electrically activated pencil-like rays to monitor narrow areas of the court adjacent to but distant from and outside of the areas in which the ball should strike if it is a 'good' ball.

Title: Matrix for injections
IPC: G09F7/00
Filed: 1979-06-18
Abstract: At daily injection of drugs, such as insulin, it is extremely important constantly to change the spot for injection and not to return to the same spot until after about a month. If you inject too often within the same area of skin there can easily appear damages to the skin such as cavities, in durations and witherings, which can result in the impaired resorption of the drug. The invention offers a possibility to distribute the spots for injection in a safe and simple way with the assistance of a matrix for injection (1) in the form of an elastic material which is cuffed around the area for injection, and the said matrix for injection (1) is provided with a number of holes (2), numbered after the days of the month and through which the injection is performed. The holes are peripherically edge-supported, and as a result of that a dome-shaped "tissue-cushion" appears when the matrix (1) is strapped, which facilitates the perforation by the needle and as a result reduces the sensitivity and promotes the resorption of the injected drug such as insulin.
