Patent GB-2069152-A (GB)
Title: Integrated circuit testing
IPC: B67C3/26
Filed: 1981-01-27
Abstract: A method of testing integrated circuits in which the supply voltage to the circuit is reduced to a value slightly greater than the marginal voltage for the circuit, the marginal voltage being the voltage at which defects in the circuit result in errors in the circuit output when a logical test is applied to it. A focussed or collimated beam of radiation is then scanned across the face of the circuit die. When the beam is directed onto the location of a fault on the circuit die, the resultant photoelectric current causes the fault to manifest itself during a logical test of the circuit and thus this fault location can be pinpointed. <IMAGE>

Title: Releasable, self-detackifying laminate construction
IPC: C09J7/29
Filed: 1981-02-06
Abstract: A laminated construction having differential release characteristics which will yield a self-detackifying adhesive surface upon delamination is produced by coating a film of a polymeric material (14) onto one side of a face stock material (10), optionally impregnated or coated with a release additive (12), and then laminating this construction to an adhesive (16) which has been coated onto a release liner (18). The release liner (18) is removed and the remaining portion of the laminate is affixed to a suitable substrate utilizing the exposed adhesive surface. The polymeric material (14) is chosen so that upon delamination of the face stock (10) from the substrate, it remains affixed to the adhesive coating. This results in a self-detackified adhesive surface on the substrate. The laminate construction is useful for tags, labels, stickers, and for sending credit, business, or membership cards on preprinted mailers to ultimate users. <IMAGE>

Title: Single facer for making single faces corrugated material
IPC: B31F1/28
Filed: 1981-02-17
Abstract: The second corrugating roll (2) of a machine for making single-faced corrugated board is provided with a number of longitudinal channels (13) each containing an insert (14).

Title: Fire and explosion detection
IPC: G08B17/12
Filed: 1981-11-27
Abstract: A system for discriminating between radiation produced by a source of fire or explosion to be detected (e.g. a hydrocarbon fire) and radiation produced by for example incendiary ammunition or pyrophoric combustion caused by an inert round has radiation detectors 10 and 12 respectively responsive to the intensity of radiation in wavelength bands at about 1 micron and 4.4 microns. Threshold units 16 and 32 respectively produce an electrical signal only when the output of detectors 10 and 12 respectively exceed a predetermined value. A rate of rise unit 24 produces a signal only when the rate of rise of the output of detector 10 exceeds a predetermined value. An output gate 18 receives these three signals and causes a delay unit 38 to produce a fire or explosion indicating output only when the output of gate 18 continuously exists for at least a predetermined period of time. <IMAGE>

Title: Analog type of electronic timepiece
Inventor: NISHIMURA KATSUO
IPC: G04C3/14
Filed: 1982-03-25
Abstract: In an analog type of electronic timepiece provided with an alarm function, means are provided whereby the timepiece hands (64, 66) are rapidly rotated into positions indicating a preset alarm time, when changeover from a normal operating mode to alarm time mode is designated, and are rapidly rotated back to indicate current time when return to the normal operating mode is designated. Signals for controlling these rapid rotations of the hands (64, 66) are generated using only two counter circuits (MC, SC), in timekeeping function circuit 96, for measuring and storing the difference between the alarm time and current time, and the system differs from prior art arrangements in that no errors are introduced into the time information during the intervals in which changeover between current time display and alarm time display takes place. A change-over control circuit (90) controls the application of timing pulses. <IMAGE>

Title: Web roll; strengthening core
Inventor: HIETANEN JUKKA
IPC: B65H75/28
Filed: 1982-06-04
Abstract: A web of material is wound onto a core by glueing the leading end of the web of material to the core 10 and by also glueing the first part of the web such that several initial layers of the web stick to each other and to the core and so thicken and strengthen the core, thus enabling a relatively weak core to be used for reeling webs of different lengths and travelling at different speeds. 
<??>A web of material (2) coming from a slitting machine (4), a sheet cutter or an unreeling frame is reeled onto a core (10), members (9) supporting and rotating the roll (11). In front of the members (9) there are members (8) e.g. sprays, rollers, brushes or scrapers which extend across the web of material (2) on that side of the web of material which will face towards the core (10), for applying a fluid substance, such as glue, water, color and/or various additives to the web of material being reeled. 
<??>The web roll may also have an outer protective wrapping composed of at least the final two layers of the web of material, glued to each other. During transporting and handling of such a strengthened and protected web roll it will not be necessary to strengthen the ends of the cores by inserts or sleeves.

Title: Tube insert
Inventor: DANIELS RAYMOND R J
IPC: B60B33/00
Filed: 1982-09-06
Abstract: A castor retaining tube insert 10 comprises a body portion 12 configured for sliding insertion into an open end of a tubular strut, an end stop 14 and a castor spigot retaining bore 16. The body portion 12 has six elongate bearing surfaces 18, 20, 22, 24, 26 and 28 arranged in a double cruciform shape, each having ramp portions, for example 36 and 38, adjacent recesses, for example 40 and 42. As the tube insert 10 is pushed into an open end of a tubular strut, the ramp portions disposed at each end of the tube insert 10 provide resistance to insertion which can be overcome by forcing the tube insert 10 into the strut. This causes excess material to be sheared from the ramp portions which can collect in the recesses adjacent the ramp portions to lessen the likelihood of the tube insert 10 jamming in the strut. <IMAGE>

Title: Adjustable backrests
Inventor: DOHERTY IAN
IPC: A47C20/04
Filed: 1982-11-02
Abstract: The invention is directed to a backrest having a locking mechanism (14) for locking the backrest in a number of different angular positions when it is mounted on a medical bed. The locking mechanism includes a handgrip (46) and, adjacent thereto, a pivotally mounted release lever or other operating member which can be operated to release the locking mechanism. The handgrip (46) and the operating member (48) are so mounted as to lie in the general plane of the backrest, and to remain in that plane, during all positions of adjustment of the backrest. In this way it becomes a comparatively easy matter for a nurse to release the locking mechanism and to adjust the angular position of the backrest using one hand only on the handgrip. <IMAGE>
