Patent GB-2204797-A (GB)
Title: Medical infusion apparatus
Inventor: FRANK PETER
IPC: A61M5/14
Filed: 1988-04-29
Abstract: Medical infusion apparatus (2) comprises a housing (4) in which a standard flexible liquid reservoir (10) is disposed. A constant-force spring applies pressure to the reservoir to force liquid out of the reservoir (10) and along a conduit to a patient. The spring (40) is energised by the opening of a lid (8) of the housing (4) which permits replacement of the reservoir (10). The liquid flowing out of the reservoir (10) passes through a moulded conduit part (12) which is configured so that it is positioned at a predetermined location with respect to a flow monitor. The flow monitor injects a pulse of heat (53), and detects the rate at which the heat pulse travels along the conduit. A microprocessor (66) uses the sensed flow rate to control a stepper motor (84) which regulates fluid flow by squeezing the conduit (56) via a spring-biased member (96). The apparatus has active and standby modes in which the monitor (74) is operated respectively more and less frequently.

Title: Open web steel joist
Inventor: HANNAH WILLIAM JAMES
IPC: E04C3/04
Filed: 1988-07-06
Abstract: A fabricated open web steel joist is provided. The top and bottom chords of the joist are each formed of L-shaped angles 20, arranged in back-to-back relation; and the web is formed of a plurality of W-shaped pre-formed bar sections 26. Adjacent ends of each of the "W"'s are located between the opposed faces of the top chord. If the joist requires an odd number of panels, a "V" (a one-half "W") is inserted between two W's within the length of joint, usually at the centre thereof. The joist is welded, with each end and each apex of each "W" and "V" being welded to each of the chord components. The assembly of the joist includes the jig assembly and clamping of all of the components of the joist, welding only the adjacent ends of the "W"'s (and "V", if used) and the apexes of the "W"'s in the upper chord first, inverting the still clamped assembly, and welding the now upper located apexes in the bottom chord. The welding is carried out in a vertical-up manner, in each instance. <IMAGE>

Title: Vehicle seat
Inventor: KOEJER WOLFGANG
IPC: B60N2/20
Filed: 1991-04-16
Abstract: A vehicle seat with a backrest that can be swung freely and with an interlock device by means of which a flipping motion of the backrest can be prevented in positive locking fashion. The interlock device has a catch lever 9 whose hinge point 12 lies between its first end section, which interacts with a stop 8 and its second end section. The latter is pivotably connected to a second lever 10 by means of a pivot pin 13 whose longitudinal axis lies parallel to the flipping axle 2 of the backrest. The second lever is connected, in the area of the stop to the part of the seat, said part supporting the stop. It is connected so that it can pivot about an axis that is parallel to the pivoting axis of the catch lever. When the interlock device is in its interlock position (Fig 1), the longitudinal axis of the pivot pin 13, the pivoting axis of the catch lever 12, and the contact point of the stop 8 for the catch lever define a triangle whose tip is formed by the pivot axis of the catch lever 12 and points towards the flipping axle. <IMAGE>

Title: A resonant scanner control system for a laser printer
Inventor: SCHERMER MACK J
IPC: G06F1/08
Filed: 1991-05-20
Abstract: A resonant scanner control system controls a laser source 10 using a pixel clock 22 which operates during an entire scan operation and tracks the pixel-to-pixel and cycle-to-cycle operations of the scanner. The pixel clock 22 includes a voltage-controlled oscillator ("VCO") whose output is controlled by the difference between a voltage corresponding to the VCO output signal and a voltage associated with pixel-related control information. The VCO output signal clocks the laser source controller 12 and a pixel address counter. The pixel address counter, in turn, addresses a memory which contains information relating pixel locations to the angular velocity of the scanner's oscillating mirror 14A, that is, the pixel-related control information. The information is converted to a voltage and applied to the VCO. The VCO adjusts its frequency in response to the difference between this voltage and a voltage related to the VCO output signal. The VCO thus supplies to the laser controller 12 a clock signal which is adjusted in accordance with the pixel-to-pixel operations of the scanner. The memory also produces, through a delay or latch, a scan synchronization signal. The phase of this signal is compared with the phase of a synchronization signal which is produced during each scan cycle at a predetermined time, to produce a phase error signal used to adjust the voltage associated with the pixel-related control information before that voltage is applied to the VCO. The VCO thus adjusts its output based on the phase error, and so effectively adjusts the phase of the pixel clock to correspond to changes in the cycle-to-cycle operation of the scanner. <IMAGE>
