Patent GB-2035905-A (GB)
Title: Printing device
IPC: B41J2/235
Filed: 1979-02-15
Abstract: A matrix printer with adjacent printing elements (41 A-41N) offset at an angle (//c) to the horizontal line direction and shifted vertically (V) sufficiently to allow the centers of horizontal lines (42, 43) of successive dots to be spaced more closely than would be possible if the centers of adjacent elements had to be vertically spaced by the diameters of the adjacent elements.
Patent GB-2060964-A (GB)
Title: Electronic time-based control system
IPC: H02J13/00
Filed: 1979-10-20
Abstract: An electronic time based control system for, for example, a domestic household, comprises a master unit 10 which is connected to a number of slave units 40 via the electrical mains circuit of the household. The slave units 40 are interposed between the main circuit and various domestic appliances whereby operation of the appliances is governed by control information generated by the master unit which, in turn, is programmable by the user so that the control signals for different appliances can be produced at pre-settable times. In their simplest form, each slave unit may comprise circuitry for detecting and unscrambling control information intended for that slave unit and a power switching element such as a triac for regulating electrical power supply to the associated appliance. Such a slave unit may be housed within the electrical plug for connecting the appliance to the mains circuit thereby obviating the need for a separate housing for each such slave unit. The control information will be superimposed on the mains supply wave form and to avoid interference between separate systems operating on the same general mains supply network, the fuse connection between the general network and the household mains circuit may incorporate a filter for preventing control signals produced by the master unit from passing into the general supply network.

Title: Liquid fuel pumping apparatus
IPC: F02M59/44
Filed: 1980-05-06
Abstract: To provide excess fuel for starting internal combustion engines a liquid fuel pumping apparatus comprises a fuel pump 10 having an axially movable quantity control member 11 connected to one end of a first lever 12 which is pivoted about a fixed axis 13. An engine speed responsive device 15 acts on the lever and a second lever 16 is provided and pivoted about the said axis. A governor spring 17 acts upon the second lever in the opposite direction to the force exerted on the first lever by the speed responsive device. After starting with lever 16 in contact with a stop 19, spring 20 is compressed by the speed sensor 15 as speed increases until magnets 22, 23 make mutual contact so that thereafter the levers move in unison until the fuel pump is stopped with the loss of sensor force so that the spring 20 overcomes the magnetic force to separate the levers ready for starting again. The magnets may be replaced in a second embodiment by a spring (26) and hook (25) Fig. 2 (not shown). <IMAGE>

Patent GB-2102737-A (GB)
Title: Printing on webs
Inventor: FISCHER HERMANN
IPC: B41F7/02
Filed: 1982-07-22
Abstract: A continuous print is produced on a half-width web (3) using one printing unit. After the first pass between the two printing cylinders (22, 23) the web is guided around a return loop in which it is laterally displaced and is then conveyed a second time between the same cylinders (22, 23). On the first pass successive first images (D1) are printed and on the second pass successive second images (D2) are printed; the length of each image (D1 and D2) is equal to half the circumference of the cylinders (22, 23) (or the sum of the image lengths is equal to the full circumference) and the length of the return loop (I1-I2) is fixed at an odd numbered multiple of the image lengths, so that the printed images (D1, D2) follow one another on the web without a gap. The loop length adjustment is made by means of displaceable rollers (24, 25). If continuous printing on one side only is required, the cylinder 23 may be an impression cylinder. The image lengths may be made longer so that partial overprinting occurs. The edges of the images should be non-straight to make the joins between adjacent images less noticeable. The printing cylinders (22, 23) may be offset cylinders applied with an image from plate cylinders. <IMAGE>

Title: Plate heat exchanger
Inventor: CROSS DONALD ANDREW
IPC: F28D9/00
Filed: 1982-09-07
Abstract: In order to weld together a stack of plates to form a heat exchanger, using laser beam welding, electron beam welding or similar processes entailing welding through the plate, the plates are formed, by appropriate through the plate welding, into sub- assemblies 1 and 21 with peripheral gaskets 8 and 23 respectively, with the peripheral gaskets 23 of the sub- assemblies 21 lying wholly within the line of the peripheral gaskets 8 of the sub-assemblies 1. This means that two sub-assemblies may then be welded together through the plate and the assembly built up in this way. The duct-forming apertures 3 and 4 of the sub-assemblies are alternately isolated from flow spaces by spacers 11 and 24 respectively. These spacers are also applied by through the plate welding and secured to the next plate by through the plate welding. <IMAGE>
