IPC: A61L/
Filed: 1980-10-16
Abstract: Protective sealing compositions in the form of molded rings or sheets for application around surgical fluid drainage openings, which compositions comprise a gelled mixture of a water-absorbing particulate hydrocolloid gum (e.g. Karayagum) and a non-toxic liquid polyhydroxy alcohol (e.g. glycerin or propylene glycol) are provided with increased resistance to the drained fluid (viz. urine or intestinal fluids) by incorporating a small amount of colloidal silica.

Patent GB-2083620-A (GB)
Title: Optical position sensor
IPC: G01B11/03
Filed: 1981-03-16
Abstract: Novel optical position sensor which, when illuminated by a lightline produces an electrical signal containing information about where the lightline strikes the surface of the sensor in relation to its origin (10). The sensor is provided with two or more detectors (5, 6, 7, 8) with wedge-shaped light sensitive area. Said detectors are located with point symmetry in relation to the origin. Two of said detectors are inner detectors (5, 6) accurately measuring the position of the lightline and located on both sides of a symmetry line (9) being parallel to the measuring direction (x) and substantially at right angles to the lightline. When the sensor is used to sense a position of an object, the lightline strikes the two inner detectors (5, 6) which are so orientated that the signal from one increases and the signal from the other one decreases if the position sensor is laterally displaced in the measurement direction (x).

Patent GB-2103393-A (GB)
Title: D.C. Motor speed control apparatus
Inventor: GRAVE GEORGES ANDRE
IPC: H02P7/282
Filed: 1982-07-02
Abstract: Pulses having a period which depends on the motor speed are derived from a series resistor (R0) and fed to a comparator (12) via a shaper (22) and an integrator (23). The result of the comparison is used as a control signal for the control circuit to maintain the motor speed at a predetermined value. In order that correction for rapid speed fluctuations should be satisfactory the control circuit is constructed to operate as a controlled voltage source the internal resistance of which is negative so as to compensate for the internal resistance of the motor. To this end it comprises a resistor (R1) the value of which is K times that of the internal resistance of the motor, a system of transistors having paralleled inputs for applying a current to the resistor and K times that current to the motor, and a difference amplifier for adjusting these currents in such manner as to maintain the voltage across the motor (which depends on the motor back emf and hence on the motor speed) equal to the voltage across the resistor. The control signal from the integrator causes an additional current (I2) proportional thereto to be drawn through the resistor.

Title: Aligning stacks of sheets
Inventor: WOOD DAVID
IPC: B65H31/34

Title: Low profile optical coupling for an optoelectronic module
Inventor: STITT ROBERT M
IPC: G02B6/42
Filed: 1983-09-14
Abstract: Means and method is disclosed for achieving a low profile optical coupling to a module comprising an optoelectronic device (2) together with other circuitry. Maintaining the optoelectronic device (2) parallel to a substrate (1) on which it and the associated circuitry are mounted enables the use of standard, well known manufacturing assembly techniques while providing electrical connection to the electric ports of said optoelectronic device (2). Subsequent to the electrical interconnection operation, the optoelectronic device (2) is moved, together with its connections (6) to a position substantially orthogonal with the mounting substrate (1), by bending a portion of a metal strip fixed to the substrate. Optical fiber (14) light coupling is utilized. The low profile of the overall module package is achieved by introducing the optical fiber (14) in a direction generally parallel with the substrate (1) and perpendicular to the light active surface of the optic port of the optoelectronic device (2), by a beat-up portion 4 of the metal strip. The structure and method are applicable to both hybrid integrated circuit assembly technology as well as to conventional metallic lead frames for plastic encapsulation. <IMAGE>

Title: Amplitude-modulated radio transmitter
Inventor: PREEDY ANTHONY REGINALD
IPC: H03C1/62
Filed: 1983-11-10
Abstract: The transmitter output is progressively compressed as the level of modulation increases; the a.g.c. mechanism of a conventional receiver provides complementary expansion. The control may be such that the peak level of the output envelope is substantially constant. A first modulator 14 modulates a carrier from an oscillator 18 with an audio input signal. A second modulator 20 modulates the output from the first modulator with a control signal Vc which is derived from the output of the second modulator 20 by a control circuit 22 effecting peak detection and smoothing. Other arrangements for high power transmitters and with feed- forward open-loop control are described. The invention reduces mean transmitter power consumption for a given service performance. <IMAGE>
