Patent GB-2105775-A (GB)
Title: Door-stay
Inventor: KARJALAINEN VAINO
IPC: E05C17/50
Filed: 1982-09-09
Abstract: A device for retaining a door or the like in an open position comprises a rotatable member (2), in bearings (4,5) provided in an aperture formed in the door. One end of the rotatable member has an actuating device (1) associated therewith and the other end thereof is in the form of a clasp (7) or hook member. The actuating device (1) is rotatable between two end positions. In one position, the rotatable member (2) permits opening and closing of the door and, in the fully open position of the door, strikes against a cushion portion (9) of a pin (8) located on the floor and acting as a limit stop. In such fully-open state, the actuating device (1) can be rotated into its other end position whereupon the clasp or hook member (7) engages the surface of the cushion member (9) remote from the door and the door is thus prevented from closing until the actuating means (1) is returned to its original position (A). <IMAGE>

Title: Electronic weighing machine
Inventor: KNOTHE ERICH
IPC: G01G7/04
Filed: 1983-05-20
Abstract: In an electronic weighing machine in which a current in a coil 9 is adjusted to balance a weight on a pan 7, pulses from an A/D converter 14 indicative of the weight are fed through an OR gate 15 and counted in a counter 16 during an active interval. In a subsequent quiescent interval clock pulses from a microprocessor 17 are fed through the gate 15 to the counter until this overflows and sets to zero. From the number of these clock pulses and the capacity of the counter the original count and thus the weight can be determined by the microprocessor and displayed. Only two lines join the counter and microprocessor. <IMAGE>

Patent GB-2181863-A (GB)
Title: Lasers
Inventor: BOWES DONALD
IPC: H01S3/134
Filed: 1986-10-27
Abstract: Laser apparatus (Figs. 11 to 14) includes linked relatively movable members with reflecting mirrors in the joints for transmitting the laser beam. The laser 10, Fig. 1 has a support tube (40, Fig. 2a, 2b) supporting and maintaining the alignment of the optical resonator structure 24, the tube containing active medium and being in communication with the discharge tube 26 in which lasing occurs. An active temperature controller maintains the gas lasing medium in the tube (40) at a substantially constant temperature above ambient by means of a temperature sensor 20 and a servo 22. An active pressure controller uses a pressure sensor 30, an electronic processor, and a motor-driven needle valve 14 to maintain the pressure of the lasing medium in the laser 10 within the desired operating pressure range. The laser can be switched in operation from a continuous mode to a pulsing mode. An active power control system (Fig. 10) maintains the power output of the laser at the desired level, through an active feedback loop in which the output beam is used to generate a voltage signal for control of discharge current. Because the optical resonator structure 24 is light weight, it can be mounted on a movable mechanical assembly (155, Fig. 11) for delivery of the beam to a desired location. The laser may form part of a distributive lasing system comprising a centralized pump 36 delivering the lasing medium to a plurality of remotely located optical resonator structures 24, each of which may have a separate heat exchanger 18 (Fig. 16b). <IMAGE>
