Patent GB-2225668-A (GB)
Title: Circuit arrangements
Inventor: WEATHERUP CLIFFORD ROBERT
IPC: H01S3/097
Filed: 1988-12-02
Abstract: An arrangement for operating a laser 1, such as, for example, a strontium recombination laser, includes a magnetic switch 2 arranged in parallel with the laser 1. When a current pulse is applied to the laser 1, the inductance of the magnetic switch 2 is initially relatively high and the beginning of the current pulse passes through the laser 1. During the pulse, the inductance of the switch drops and the remainder of the pulse is then transmitted through the switch 2, bypassing the laser 1. This enables a pulse having a fast fall time to be applied to the laser 1 which is particularly advantageous for recombination type lasers. A load other than a laser may be included in the circuit. <IMAGE>

Title: Work platform and connector therefor
Inventor: MARTIN NORMAN GEOFFREY
IPC: E04G1/32
Filed: 1989-07-13
Abstract: A connector (2) for use in constructing a work platform has guide channels (6) for legs joined by a cross member (4) which bears a deck (28) and by a second cross member (8) below. A platform is assembled from two such connectors, a deck (28) and four legs (34). Restraining means (18) extend (30) at least partially over the deck (28) and hold it onto each connector (2) allowing the entire platform to be picked up as one piece. The legs (34) are held by clamps (10) which press them into the guide channels. Teeth (9, 11) on the clamps and in the channels engage the legs. A step 36 may be fitted around a leg 34 and is adjustable along the leg by tilting the tread plate 38 upwardly against the bias of a tongue 52 thereby disengaging teeth 49, 50 from the leg 34, so that the step can be slid up or down the leg 34. When the step is released the tongue 52 will bias the teeth 49, 50 into contact with the leg 34. <IMAGE>

Title: Angler's seat or bedchair
Inventor: FOX CLIFFORD ROYSTON
IPC: A47C9/10
Filed: 1989-12-22
Abstract: A seat or bedchair having individually telescopically adjustable logs (10, 14), each such leg (10, 14) being provided with ratchet means (12, 32) which enable the leg (10, 14) to be increased in length relatively freely, but which resist subsequent shortening of the leg (10, 14). As a result, once a suitable position, for example on the bank of a river, has been located, the angler's seat or bedchair may be placed on the ground and each of its legs (10, 14) may be individually adjusted simply by pulling the lower pan of the log (10, 14) downwardly until it reaches the desired length, the ratchet means (12, 32) preventing the collapse of the leg (10, 14) when the user sits on the seat or bedchair. <IMAGE>

Title: Improvements in apparatus for use in stethoscopy
Inventor: HOWELL DEREK
IPC: A61B7/04
Filed: 1959-09-04
Abstract: 893,939. Stethoscopes. FARADAY ELECTRONIC INSTRUMENTS Ltd. Aug. 31, 1960 [Sept. 4, 1959], No. 30270/59. Class 40 (4). In stethoscopic apparatus including a microphone 1, an amplifier 6 and a sound reproducer 7, the microphone output is connected to a frequency doubler 3 or other harmonic converter. The harmonic signals may pass through a low-pass filter 4 which cuts-out frequency components above 200 cycles per second and acts as a feedback trap. A potentiometer 5 has a slider 5a which may be positioned so that substantially only the output from the harmonic converter is applied to the loud-speaker, or so that the harmonic converter and low-pass filter are substantially by-passed. In intermediate positions of the slider 5a the loudspeaker is fed partly with signals from the harmonic converter and partly with signals by-passing the harmonic converter. The frequency doubler employs crystal diodes in a full-wave or bridge circuit. The stethoscope is for listening to weak low-frequency sounds such as the heart beats of an unborn baby. Specification 798,825 is referred to.
Patent GB-2230114-A (GB)
Title: A switch-mode power supply
Inventor: LEONARDI GIOVANNI MICHELE
IPC: H04N5/63
Filed: 1990-03-06
Abstract: A first switching transistor Q2 is coupled to a primary winding W1 of an isolation transformer T2. A secondary winding W2 of the transformer T2, is coupled via a switching diode D3 to a capacitor C4 of a control circuit 120 for developing a DC control voltage V4 in the capacitor C4. The DC level of the control voltage V4 varies in accordance with a B+ supply voltage. A change in B+ voltage produces a corresponding greater change in the control voltage V4. The control voltage V4 is applied to the transformer T2 when the diode D3 is conducting, for producing a pulse-width modulated control signal V5. The control signal V5 is applied to a mains coupled chopper transistor Q1 for generating and regulating the B+ supply voltage in accordance with the pulse width modulation of the control signal V5. In standby operation low power operation is provided by burst mode switching operation of oscillator 110 which occurs during an interval (t10-t12, Fig 5), the oscillator being periodically triggered by half wave rectified voltage of signal V7 at mains frequency. A soft start up is provided whereby the power supply operates initially in the burst mode until started. <IMAGE>

Title: Damping force adjusting hydraulic shock absorber
Inventor: ASHIBA MASAHIRO
IPC: F16F9/46
Filed: 1990-03-16
Abstract: A damping force adjusting hydraulic shock absorber comprises a damping force regulating valve (12) constructed of a plurality of valve bodies (42, 43) for opening and closing one of passages (13) connecting two chambers (4, 5, Fig 1). A spring member (46, 47) is provided on each valve body for biasing the valve body onto a valve seat (40) provided in the passage (13) and a plunger (52) is mounted on the valve bodies. A solenoid (53) into which the plunger is inserted moves the plunger by means of a force corresponding to the value of a current to successively operate the valve bodies. The passage is thus adjusted by controlling a current value, a damping force is then generated by damping force generating mechanisms (18, 26, Fig.1) for controlling a flow of hydraulic fluid in the passages (13, and 14, 15, Fig.1) and so obtaining a plurality of damping force characteristics.
