Title: Methods of manufacturing liquid jet recording heads
Inventor: NOGUCHI HIROMICHI
IPC: B41J2/045
Filed: 1987-04-23
Abstract: As described, a lower substrate 1 is provided with a layer of selectively removable material over areas where ink channels 13 are to be formed, and a layer of uncured radiation-curable material 10 is applied overall. After emplacing the upper substrate 4, the device is irradiated through a mask such that the ink chamber area 12 is not exposed, whereby the unmasked areas of material 10 are cured and adhere to the substrates. The selectively removable channel formers and the uncured material 10 defining the ink chamber 12 are then removed to complete the device. The selectively removable material may be: 
 
  (i) a dry film photoresist which has been shaped to define the channels by exposure and development 
  (ii) a solvent soluble polymer which has been shaped by masking with a resist, exposing and developing the resist, and dissolving the unmasked polymer 
  (iii) a pattern printed in resin.

Title: Device suitable for the administration of a therapeutic substance
Inventor: RAYMAN GERRARD ABDOOL
IPC: A61M5/14
Filed: 1987-07-24
Abstract: The invention relates to a device suitable for use in the intermittent or even continuous administration of a therapeutic substance such as insulin or morphine. The device comprises a cannula (1) of biocompatible plastics material for indwelling in a patient and defining a through-passage (16), together with a hub (2) also defining a through-passage (3). The respective cannula and hub passages are isolatable from each other by separator means such as a self-sealing diaphragm (8) disposed between them. In the device the arrangement of the respective passages themselves together with said diaphragm or the like is such as to permit a needle (14) to penetrate the hub and cannula through them and, when necessary, to extend beyond the distal end (1') of the cannula. The through-passage of the hub is also constructed and arranged so that it guides an injection needle passed therethrough to pass through the diaphragm (8) at a position where the needle is aligned with the through-passage (16) of the cannula.

Title: Door stop
Inventor: WARD ALAN STEPHEN
IPC: E05C17/48
Filed: 1988-01-06
Abstract: A door stop comprises an upstanding stop member 6 projecting upwardly through an aperture in an arcuate guide channel 2 carried by a base for mounting on the floor adjacent the leading edge of the door. The stop member carries transverse lugs 7 to reduce tilting and is preferably spring loaded. It may be rubber covered. The stop member travels from an inoperative position Y outside the arc of swing of the door to an operative position Z within the arc so as to prevent the door from being opened further. Between the extremities at an intermediate position shown the stop lies closely adjacent the face of a closed door whereby the stop cannot be released until the door is closed - this cannot be done by a potential intruder. <IMAGE>

Title: Remote control mechanism
Inventor: DUNCAN COLIN ERIC
IPC: F16C1/10
Filed: 1988-01-21
Abstract: A control member (1,2,3) for opening an engine choke or other element is axially displaceable relative to a fixed housing (6) against a resistance imposed by a spring (13) acting against a transverse bar (14) which bears against the control member. The housing (7) defines a cavity which opens transversely with respect to the axis of the control member (1,2,3) and is provided with guideways (17,17') along which the opposed ends of the bar (14) are slidable. For assembly purposes, the bar (14) is insertable from the open side of the cavity into a position in which the control member 1,2,3 can be axially threaded through the housing, beneath the bar. The spring (13) can form part of or make contact with an electrical terminal (9, 11) via which an electrical circuit is closed when the control member (1,2,3) is displaced to bring the bar (14) into contact with an electrically conductive part (2) of such control member. <IMAGE>

Title: Improvements in sealed cable glands
Inventor: WALES ALAN CHARLES DURWARD
IPC: H02G3/06
Filed: 1988-04-13
Abstract: A cable gland assembly comprises a plastics gland body (12) through which a cable (36) passes. An internally threaded plastics compression nut (24) engages one end of the body.

The sleeve resists the tendency of the engaging threads on the body and nut to ride over one another as the nut is tightened. The radially inner surface (28) of the sleeve is tapered to urge a sealing ring into sealing contact with the cable. The other end of the gland body projects through an aperture in a wail and is secured in place by an internally threaded retaining ring (40). The ring has at least one radially projecting lug (42, 52) provided with an electrical connector (46), for connecting to the cable armouring (50). <IMAGE>

Title: Time controller
Inventor: COLLINS RODERICK JOHN
IPC: G05B19/045
Filed: 1988-07-13
Abstract: A controller, for example for a central heating/hot water heating installation, comprises an electronic logic and timing device including ROM (1) and RAM (2) circuits programmed, preferably during its manufacture, to perform a set of one or more 'on' switching operations and one or more 'off' switching operations at pre-set invariable times relative to one another but independently of real time. The RAM and ROM circuits are interfaced with an output stage (4) by a comparator (3), the output stage including a solid state switch (6) for switching the load 'on' or 'off' as the case may be. In use, the controller performs its functions in a pre-determined order relative to real time upon actuation of a start switch (5). The controller obviates the need for the relatively expensive user-programmable facilities, time display etc of conventional controllers. <IMAGE>

Patent GB-2237470-A (GB)
Title: Intruder alarm system
Inventor: ALDRED IAN RICHARD
IPC: G01S13/04
Filed: 1990-08-17
Abstract: An intruder alarm system using FMCW radar. An FMCW signal (16) is generated (21) and mixed (25) with reflected signals (17) to produce an output signal (15) having a frequency dependent on range. The output signal (15) is applied to a threshold circuit (34) which triggers (T) the alarm (31, 32) on detecting the relatively sudden change in signal amplitude caused by a disturbance. The threshold circuit produces a dynamic threshold comprising upper and lower thresholds either side of a threshold determined by the running average of the output signal. Only sudden changes relative to background are thus detected. The output signal (15) is filtered (28, 29) so that the system is responsive only to disturbances occuring within predetermined range limits. The filter (28) characteristic is chosen so as to tend to suppress the effect of range on the amplitude of the reflected signal (17), thus providing a substantially constant sensitivity to disturbances over the operative range. <IMAGE>

Title: Socket wrench
Inventor: HSU C C FRANK
IPC: B25B13/46
Filed: 1990-12-05
Abstract: The wrench includes a pair of rollers 21 connected by an eccentric shaft 22 received in a box end 11. A C-shaped ring 30 with two arms 35, 36 is rotatably mounted on the eccentric shaft 22. A gradually narrowing space is formed between the outer surface of the eccentric shaft 22 and the inner wall 121 of the box end. A pin 50 connects the pair of rollers 21. One arm 36 of the C-shaped ring 30 is associated with the pin 50. When the handle 13 is rotated in a first direction, the arm 36 abuts the pin 50, thus preventing the arm 36 from moving into the narrowing space. When the handle 13 is rotated in the opposite direction, the arm 36 moves away from the pin 50, and the other arm 35 wedges into the narrowing space, thus driving the wrench. <IMAGE>
