Title: Pressure variation absorber
IPC: F04D29/66
Filed: 1978-07-12
Abstract: Pressure variation absorbing apparatus (10) is mounted adjacent to a moving fluid stream in the diffuser (14) of a centrifugal compressor for absorbing both acoustic and aerodynamic pressure variations. The absorbing apparatus (10) when mounted as a part of the diffuser wall of a centrifugal compressor not only reduces acoustic noise but also absorbs aerodynamic pressure variations increasing the efficiency of the compressor and simultaneously reducing the rate of flow at which surge occurs thereby enlarging the operational flow range of the compressor. A method of absorbing pressure variations in a moving fluid stream is also disclosed.

In an example the device is used to indicate the times of operation of hair driers, in which the. drier represented by the peg 8 was started at five minutes past 10 o'clock, the colour of the peg indicating the hour from 10-11 and its position around the clock indicating the minute of starting. Since the clock as shown indicates 10.35 then drier number 8 has been running for half an hour. Spare pegs are kept in holes at the top of the board 1.
Patent GB-2044966-A (GB)
Title: Apparatus for selectively reproducing engineering drawings by computer
IPC: G06T11/20
Filed: 1979-01-10
Abstract: A computer has an address coded store of flow diagram symbols, circuit wiring diagram symbols and schematic circuits of the related instrumentation and control systems and interfaces, and other data relating to cable schedules for said systems. Input sheets are matrix coded so as to receive the symbols and data relating to the respective flow diagrams and circuit wiring diagrams whereby input data is transferred, with the aid of matrix coding, to the computer store. This provides the advantage that an engineer prepares the input sheets but these are readily interpretable by a teletype operator. A further advantage is provided in updating the drawings to show amendments, by collating input sheets prior to data transfer to the computer. A plotter and/or printout device reproduces the stored symbols and data, the computer being programmed to selectively reproduce the stored symbols and data. On a given input request, a drawing is reproduced in a single sheet format wherein designated areas contain a flow diagram, the wiring diagram showing the respective control/instrumentation interface, the schematic diagram and the cable schedule for the respective process or part process. Secondary drawings may be reproduced which illustrate a particular component or components which are in store for reproduction of one or more of the single sheet format drawings.
Patent GB-2015194-A (GB)
Title: Sewing Machine with Microprocessor Control
IPC: G05B19/414
Filed: 1979-02-08
Abstract: A sewing machine of the domestic type has a needle bar, a feed dog and an actuator which adjusts the transverse position of the needle bar and the positional displacement of the feed dog in response to control signals provided thereto. A microcomputer integrated circuit is provided for controlling the machine in response to keyboard-selectable pattern and control information stored in a static memory which is interchangeable with other memory configurations to provide different patterns. such as alphabetic stitch patterns. The keyboard contains a numeric display with each of the patterns having a corresponding numeric equivalent which is displayed on the keyboard to indicate which pattern is selected. The microcomputer is capable of selectively and controllably operating on the stored stitch pattern data in response to input control signals from the keyboard for controllably redefining the stored stitch pattern data to selectively create output control signals for the actuator different from the output control signals corresponding to any one of the stored stitch patterns, whereby the position of the stitch framing instrumentalities may be selectively varied to redefine a stitch pattern arrangement different from any one of the stored stitch patterns. Thus, for example, a constant stitch density may be maintained for a selected pattern as the length of the pattern is varied by the operator in such a manner that the selected stitch pattern shape may be maintained, such as by interpolating the stored stitch pattern data to create additional associated stitch position coordinates which were not contained in the stored stitch pattern data. As another example, a plurality of stitch patterns may be combined by the operator by selecting the combining function which alternates between selected patterns a stitch at a time. <IMAGE>

Patent GB-2065725-A (GB)
Title: Producing bobbins
IPC: B65H63/08
Filed: 1980-11-26
Abstract: Cross-wound bobbins each of which has at least approximately the same length of yarn are produced on a rotor spinning frame 1 with an automatic doffing device 2. The rotor spinning frame 1 has a length measuring device 5, preferably a pulse counter, which produces values corresponding to the length of yarn on each cross-wound bobbin. These values are stored in a calculator unit 4. Immediately before reaching the desired length on a bobbin, the doffing device 2 is caused by a signal from the calculator unit 4 to move to the relevant cross-wound bobbin and where it waits until another signal from the unit 4. This other signal indicates the desired yarn length and initiates the doffing of the fully wound cross-wound bobbin. <IMAGE>

Title: Improvements in or relating to linings and heating element supports for furnaces
Inventor: BROWN WILLIAM LYALL
IPC: H05B3/66
Filed: 1981-08-12
Abstract: A support system for a furnace heating element. Furnace linings use traditional refractory bricks, having grooves therein forming shelf supports for heating elements. These bricks suffer from the disadvantage that they deteriorate when subject to rapid temperature changes. Ceramic fibre, can withstand these rapid temperature changes but constructing a ceramic fibre brick with grooves for supporting the elements is wasteful of materials and can lead to overheating of the elements. In order to overcome these problems one embodiment of the present invention provides a ceramic fibre board 1 which has grooves machined therein and in which are received respective strip-like ceramic fibre member 7 which define shelf supports for the furnace heating elements. The shelf supports are inclined at 60 DEG to the face of the board. <IMAGE>
