Patent GB-1338382-A (GB)
Title: Demand pacemaker
IPC: H03K3/26
Filed: 1969-12-02
Abstract: 1338382 Transistor pulse generators DEVICES Ltd 27 Nov 1970 [2 Dec 1969] 58896/69 Heading H3T [Also in Division A5] A demand pacemaker comprises a pulse generator for generating artificial stimulating pulses and having a variable delay between pulses controlled by a timing circuit, a feedback circuit for passing artificial or natural stimulating pulses as reference pulses to set the timing circuit to an initial condition, the generator being such that it generates a pulse after a delay time following the setting of the timing circuit unless a natural stimulating pulse occurs within the delay time, there being provided means for detecting whether artificial or natural stimulating pulses are being issued and means for lengthening the delay time when natural pulses are being issued. In one embodiment the pulse generator consists of transistors VT16, VT17 triggered at a predetermined potential on capacitor C19 which discharges through R41, R42. After being amplified by transistors VT 18, VT 19 pulses are applied to electrode 2 on the heart. Natural stimulating pulses are passed through a feedback path 3 causing transistor VT15 to conduct, increasing the charge on capacitor C19 which has the effect of reducing the natural frequency of the pulse generator. Artificial stimulating pulses are taken from the collector of transistor VT19 via resistor R103 to charge capacitor CA. When capacitor CA reaches a predetermined potential transistor VT21, which is shunted across capacitor C19, becomes conductive and assists the discharge of the capacitor, thus tending to increase the frequency of the pulse generator. When natural stimulating pulses are received the effect is to prevent the generation of artificial pulses and when 'the latter are generated they are repeated at a frequency determined in a fixed or progressively variable manner by capacitor CA, transistor VT21 and their associated components until a natural stimulating pulse is received again. In a second embodiment, Fig. 2 (not shown), the pulse generator consists of a timing transistor (TR9) controlled by a timing capacitor (C11) and resistor (R22), pulses from (TR9) triggering a monostable circuit (TR10, TR11). Natural pulses from a feedback path (3) cause a transistor (TR8) to conduct and discharge timing capacitor (Cll). Artificial pulses taken from the collector of transistor (TR11) are passed via a diode (D5) to a capacitor (C12) thereby changing the biasing of timing transistor (TR9) and therefore also the level at which it triggers.

Title: Improvements in plastics bags
IPC: B29C53/36
Filed: 1967-12-29
Abstract: 1,210,259. Seaming non-metallic sheet material. ZELLSTOFFABRIK WALDHOF. 29 Dec., 1967 [31 Dec., 1966], No. 59017/67. Heading B5K. [Also in Division B8] A multi-layer plastics bag made from flattened tubular plastics film, e.g. of polythene, has a longitudinal seam formed by joining together only the inner adjacent layers of overlapping longitudinal edges of the flattened film, the seam being formed substantially in the middle of the overlap. The edges of the flattened tubular film overlap each other by at least 10 mm., preferably at least 20 mm. Preferably, to produce the longitudinal seam a bonding agent, e.g. a thermoplastic thread or tape, is interposed between the overlapping edges in a warm state and secured by applying pressure. In an example a two-component bonding agent dissolved in a solvent is applied to the overlapping edges. The solvent is evaporated prior to formation of the seam by blowing hot air thereon. After overlapping the longitudinal edges of the flattened film, pressure is applied by rolling or calendering. Sections are cut from the continuous web and stacked. To produce a four-layer bag or sack two doublelayer tubular films in accordance with Fig. 1 are inserted one inside the other, Fig. 2 (not shown).

Filed: 1978-11-03
Abstract: A brush for finishing leather, skins and like materials in sheet form is disclosed, which is composed by an elongate inflatable air bag 5 on which a material 6 such as velvet or fabric is removably fastened so as to be interchangeable. The brush is for being mounted on a finishing machine which spreads by means of such brush a layer of varnish, lacquer or any other processing liquor on the skins or like materials to be finished. The adjustable resiliency, which is due not only to the intrinsic elasticity of the material the bag is made of (e.g. rubber), but also to the pressure of inflation in its interior, automatically balances any thickness unevenness on the surface of the material being treated. <IMAGE>

Patent GB-2049974-A (GB)
Title: Methods and apparatus for recording electric signals
IPC: G02F1/03
Filed: 1980-04-23
Abstract: When recording electric signals on a photosensitive recording medium 19 with the aid of an array of electrically switchable light gates 15 employing certain electrooptically active light gate materials such as PLZT, it has been found that the transparency to a light source 13, such as a mercury arc lamp, declines with length of use. The latter decline, believed to be due mainly to photo-induced birefringence, is avoided by eliminating charge trap areas and minimising a buildup of space charges in the light gate material; for example, the arc light may be filtered to remove the shorter wavelengths causing the photo-effect, or a sodium vapour lamp with a glass bulb may be used to similar effect, or in the case of an array with electrodes on any one surface, the beam 14 may be incident on the opposite surface. <IMAGE>

Abstract: An electrical connector comprises an integrally molded housing having a dead-front base through which electrical contacts extend and a pair of rigid side covers (240, 260) pivotally connected to it by web hinges (210, 211). The side covers fold about the web hinges to: (i) force insulated cord conductors into insulation displacement terminals (206) which form part of the contacts and which are fixed to the base and thus wire the connector: and (ii) safely enclose the wiring area. The side covers are also locked to the dead-front base by the engagement of mating portions of the covers and base to prevent relative motion should the web hinges fail. The connector can have male 202 or female contacts or both. <IMAGE>

Abstract: In a flow meter of the type comprising a rotor consisting of a spindle 12 and bearing heads 9 and 11 cooperating with seats 5 and 6 to give support of the rotor, it has been found that the flow does not split evenly between the ends. In order to improve the flow performance, the flow characteristics of the two heads 9 and 11 are chosen to be different so as to have their transitions from laminar to turbulent flow occuring sequentially. It is preferred that the turbine means on the rotor be formed by angled passages through the bearings heads 9 and 11. <IMAGE>
