Title: Microwave detection circuit
IPC: G01S13/56
Filed: 1980-04-09
Abstract: In order to prevent false triggering of a microwave motion detecting device, such as an intruder detector, the device comprises a detection circuit including two wave shapers 4 which shape the input signals received from a transmitter/receiver waveguide 1 by continuously comparing the input signals to a reference voltage which varies in accordance with the input bias and emitting a high level or a low level signal in dependence on the result of the comparison. The level of the input signals is monitored by a level detector 8 and the phases of the shaped signals are compared by a phase detector 5. When the outputs of the detectors 5 and 8 indicate the presence of an object which is changing its distance from the device an alarm is triggered by a relay circuit 12. <IMAGE>
Patent GB-2053465-A (GB)
Title: Photoelectric flaw detection
IPC: G01N21/89
Filed: 1980-06-26
Abstract: An optical inspection system for detection of flaws in a moving web by scattering of dark field illumination, comprising a radiation source (not shown) and an optical stop 1 in the plane of received radiation in order to give dark field inspection of an image plane by a photocell 4, has means for correcting misalignment of the stop. The stop comprises a bright metal wire 1 mounted on the pointer 2 of a galvanometer 3. Two photocells 5 and 6 are so located that in normal conditions they receive equal amounts of radiation reflected from the wire 1 but when the wire becomes misaligned radiation striking the wire is reflected preferentially onto one or other of the two photocells. The signal from the photocells 5 and 6 actuates the galvanometer to bring the optical stop into alignment with the radiation. Alternatively the galvanometer pointer may carry a mirror which directs the light onto a fixed wire (Fig. 3 not shown) or a pair of galvanometers operating at right angles may carry mirrors which direct the light onto a convex optical stop viewed by four photocells for misalignment correction in two directions. <IMAGE>

Title: Head rest stay retaining device
Inventor: YOSHIDA YOUKI
IPC: A47C7/38
Filed: 1981-06-22
Abstract: A stay (3) supports the head rest such that the head rest can be adjusted for height. The stay (3) is provided with a continuous, engagement face (4) which has a predetermined length in a direction along the axis of the stay (3). The retaining device further includes a support cylinder (5) provided in the back of a seat to guide the stay (3) and a pushing member (8) having an engagement face which is urged into contact with the engagement face (4) of the stay (3). The stay (3) is retained due to the engagement of the engagement faces. Preferably, the engagement face (4) on the stay (3) tapers towards the axis of the stay from the upper portion of the face (4) to the lower portion thereof. Such taper enhances the safety aspect of the head rest since any sudden downward force tends to produce an increase forced contact between the engagement faces. The surface of one or both engagement faces may be corrugated so as to enhance frictional contact between the faces, and various alternative constructions for the pushing member are disclosed. <IMAGE>

Title: Laser cutting apparatus and method
IPC: B23K26/36
Filed: 1981-12-10
Abstract: An apparatus and method for cutting material from a workpiece uses a laser resonator emitting an essentially coherent beam of electromagnetic radiation having at least partial linear polarization and a converting means converting the linearly polarized laser beam into an essentially coherent beam of electromagnetic radiation having at least partial circular polarization. A directing means ensures that the circularly polarized beam is directed against the workpiece at the point of the desired cut. A conventional focusing means and axially directed gas jet may be added to enhance the cutting of the laser beam. The use of a circularly polarized beam is said to reduce key angulation and improve cut surface smoothness.

Title: Improvements in or relating to decision circuits
Inventor: PASKI ROBERT MARK
IPC: H04L25/06
Filed: 1984-05-01
Abstract: A decision circuit (20) is responsive to digital input signals (22) and to timing signals (21) for reshaping and retiming the input signals into reshaped and retimed output signals. The decision circuit also is responsive to the digital input signals and absence of the timing signals for reshaping but not retiming the digital input signals into reshaped output signals which are transmitted. Thus the circuit produces and transmits reshaped output signals even upon failure to apply the timing signals as required by previous decision circuits. The reshaping is brought about by non-linear characteristics of quantiser 30, as well as latches 41,42 which are designed to achieve non-linear reshaping when the absence of timing signals prevents latching. <IMAGE>
