Patent GB-2149304-A (GB)
Title: Liquid dispensing device and air freshener
Inventor: WRIGHT REGINALD PETER
IPC: A61L9/03
Filed: 1983-11-05
Abstract: The present invention relates to a liquid dispensing device which can automatically dispense a dose of a perfumed composition at regular intervals to freshen air within, for example, a room. The device according to the invention for dispensing droplets of a liquid composition in a controlled manner comprises at least one container to provide a reservoir of the liquid to be dispensed and a rigidly-contained volume of gas in communication with the reservoir. The device also includes a dispenser arranged to receive liquid to be dispensed from the reservoir, the dispenser, reservoir and gas volume being associated in a manner such that liquid is held in the reservoir against a flow resistance having a value high enough to prevent dispensing of liquid in the absence of a rise in temperature of the gas when the device is disposed for dispensing. However, the dispenser is also arranged so that one or more droplets can be dispensed as desired by raising the temperature of the gas to increase its pressure to that necessary to overcome the flow resistance and to force one or more droplets of said liquid to be dispensed through the dispenser. <IMAGE>

Title: Line spacing mechanism for electronic typewriter
Inventor: GUBAU GIUSEPPE
IPC: B41J7/48
Filed: 1983-12-12
Abstract: A platen 23 is rotated by an attached ratchet wheel 147 driven by a pawl 152. A lever 148 determines the number of ratchet teeth over which the pawl operates so as to determine the line spacing increment in known way. The pawl is mounted on a lever 146 which is oscillated by a strut 149 driven by a cam follower lever 145 cooperating with a cam 143 driven by a dc motor 140 via reduction gears 141. A second cam 142 controls a changeover switch 144 which controls the energisation of the motor 140 in such a way that single cycles of the cam shaft are performed in response to each line feed command. <IMAGE>

Title: Railway track maintenance
Inventor: COOPER JAMES
IPC: E01B27/18
Filed: 1984-01-04
Abstract: A railway track is maintained by raising the sleepers (as by apparatus 8), placing beneath them packing layers of settable plastics material or fibrous concrete (as from a tank 14 through line 16) and lowering the sleepers onto the packing layers as soon as these have sufficiently set to support the sleepers. Where the material of the packing layer is initially readily flowable, flow can be restrained by reducing the porosity of the adjacent ballast (as by applying sheet material or by using device 10 to inject a chemical bonding agent into the ballast). <IMAGE>

Title: Increasing keyboard functions by depressing a plurality of keys simultaneously
Inventor: LAPEYRE JAMES MARTIAL
IPC: G06F3/14
Filed: 1984-01-12
Abstract: A key board has a geometric arrangement having intersections of three keys achieved by offsetting or staggering adjacent keys. This provides a greater number of choices from a given number of keys actuable manually one, two or three at a time. The key layout permits touch typing with one hand where twelve keys provides full alphanumeric capabilities. Finger positions conform with human hand structure and include raised ridges for identifying some of the fingerstroke key selection locations. Thus, accurate high speed typing with either hand is feasible in a telephone dial space frame. The keyboard communicates by an X by Y communication channel matri or telephone system compatible tone signals with computers, telephones, teletypes and like utility devices. Program steps and function selection is afforded by a self cataloged two (or more) keystroke sequence to reduce programming time and increase the number of selections possible per key. Thus, as few as four keys and four wires can afford fourteen manual selections by a single finger stroke in a single live key mode. <IMAGE>

Title: Door safety device
Inventor: OATLEY GERALD ARTHUR
IPC: E05B17/00
Filed: 1984-02-16
Abstract: A hinged door 1 has a safety device to reduce the risk, when the door closes, of fingers being trapped, particularly at the hinged end of the door. The safety device comprises a bolt 4 which is spring-loaded so that it normally protrudes beyond the edge of the door and strikes the door frame 2 before the door closes to a dangerous extent. The bolt 4 is coupled by a Bowden cable 7 or other linkage to the door handle 3. The bolt 4 can be withdrawn, to allow the door to close, by turning the door handle to retract the latch. A deliberate act of retracting the door latch is therefore required before the door can be shut. The bolt 4 may be made up of rubber or other resilient material to avoid damage to the frame. The actuating mechanism 6 for withdrawing the bolt 4 may be separate from the latch mechanism and mounted between the door surface and the usual face plate surrounding the spindle of the door latch. <IMAGE>

Title: Improvements in or relating to video player control
Inventor: KERR GORDON WILLIAM
IPC: G11B21/08
Filed: 1984-09-10
Abstract: A position search control arrangement is provided which enables searching to be performed on video players not provided with this function together with automatic restoration of playing position upon power-up following a mains failure during play. A data stripper removes encoded data from the playback signal to produce a current value of a positional variable (frame number, chapter number or time code). This is compared with a desired value and the player controls actuated in accordance with the difference. This may be by operating semiconductor switches in parallel with the player's mechanical switches, or by feeding a signal which simulates remote control signals, or by actuating the player's keys by suitable electro-mechanical devices. The control arrangement includes a periodically updated non-volatile store which is used to set the desired value upon power-up following a mains failure. The control arrangement may be incorporated in an "intelligent" video disc player.

Title: Slotted waveguide antennas and arrays
Inventor: SANGSTER ALAN JOHN
IPC: H01Q21/00
Filed: 1986-02-05
Abstract: Array antennas constructed from some forms of waveguide radiators with sidewall slots exhibit cross polarisation and periodic errors. This problem arises from the difficulty of obtaining phase reversal in the radiation from adjacent slots in such a radiator other than by slot inclination. The present invention offers two solutions. Firstly, a radiator 10 having a number of non- inclined sidewall slots such as 13 and 14 and a septum 15 with inclined slots such as 25 and 26 which provide a phase relationship in the radiation from the sidewall slots which ensures that no significant cross polarisation errors nor grating lobes occur. A number of radiators 10 can be used to form an array. Secondly, arrays using radiators with sidewall slots, in which the distance between these slots, the dimensions of the radiators and the relative positions of individual radiators are such that the phase relationships in radiation from the slots of the array prevent significant grating lobes (Fig. 5). <IMAGE>
