Title: Colouring contact lenses with reactive dyestuffs
Inventor: KAI CHIANG SU
IPC: G02B1/04
Filed: 1982-08-06
Abstract: Contact lenses comprising polymeric lens materials are coloured by reactive dyestuffs covalently bonded to monomer units of the polymer backbone, said dyestuffs being reactive dyes capable of forming ether linkages with cellulose, and being reactive with hydroxyl, amino, amido or mercapto groups present in a hydrogel polymer to form the covalent bond therewith. The invention is of particular interest in the area of "soft" contact lenses (hydrogel lenses).

Title: Monitoring the sealing- tightness of an internal combustion engine valve by temperature detection
Inventor: EBERLE MEINRAD
IPC: F16K1/34
Filed: 1982-08-31
Abstract: At least one temperature sensor 36, 48 disposed in the valve seat 18 or the valve head 23 monitors the temperature at at least one location on the seat or head. This temperature may be compared with the temperature at another location, e.g. diametrically opposite, on the seat or head or with the gas temperature in the flow passage controlled by the valve.

Title: Pneumatic spring acting as electrical switch
Inventor: LOPEZ JUAN ANGEL USATEGUI
IPC: F16F9/02
Filed: 1984-08-16
Abstract: A pneumatic spring such as is used to assist the opening and closing of vehicle bonnets includes a conducting tongue 6 attached to the piston 3 and ring 7 at the bottom of the cylinder. In the extended position, the tongue 6 contacts the cylinder 1 and a circuit is established between terminals 8 and 9, while in the contracted position, the ring (if insulating) interrupts the connection between tongue and cylinder. In an alternative embodiment, the tongue does not extend as far as the cylinder wall but does make contact with the ring, being of smaller internal diameter. In this case, the ring is conductive and completes the connection when the spring is contracted. The device can switch on, for example, the internal light of a car bonnet. <IMAGE>

Patent GB-2156155-A (GB)
Title: AC circuit controller
Inventor: ARROWSMITH COLIN
IPC: H01H9/56
Filed: 1985-03-07
Abstract: An a.c. circuit controller utilises a control circuit 12 which produces a pulse train substantially synchronised with a.c. zero crossings when a load L is to be energised. To randomise the direction of zero-crossing at which switch-on occurs and thereby protect a relay RL which has contacts RL1 in parallel with a load controlling semi-conductor switch device Q1 from contact damage caused by relay contact material transfer, an integrator R7, C6 is provided to integrate these pulse and provide a staircase waveform. A comparator A1 detects the level of this staircase waveform and controls firing of Q1 and energisation of the relay RL. In another embodiment (Fig. 2, not shown) the direction of zero crossings sensed by a digital circuit controlling the switch device and the relay is changed at the end of each cycle of operation. <IMAGE>

Title: Packet switching system
Inventor: ROUS RONALD FRANK
IPC: H04B3/20
Filed: 1985-03-13
Abstract: In a packet switching system in which speech is packetised, voice activity detectors (VAD's) (2,3) are used to monitor speech in the GO and RETURN paths. In the GO path, the VAD(2) compares the current level of packets with (a) the current background noise value, and (b) the computed value of the expected echo due to speech packets in the RETURN path. If the GO path packet is larger than the parameter of (a) and (b) by a preset arrangement the packet is set, otherwise it is not. If the "send" decision persists for a number of speech packets, that send condition has a hangover period attached to it. If the parameters are properly chosen, then the speech as heard by a subscriber is not unduly affected. <IMAGE>

Title: Procedure for unrolling a machine roll of paper tissue
Inventor: VAINIO PERTTI
IPC: B65H16/10
Filed: 1985-05-31
Abstract: Measurement data required to control the unrolling web speed of paper tissue in a heavy primary or "machine" roll (10) are derived from the surface of the tissue machine roll (10) by means of a separate tachometer generator (12) driven by a speed measuring means in the form of a small- dimension endless belt (13) (or equivalent roller) mounted to contact the surface of the unrolling tissue. This area is compared (at 19) with a desired reference speed and any difference is fed back to control means (17) which controls a drive means (14) acting directly on the shaft of the machine roll. Thus in comparison with known power transmission by surface-belt drives for the machine rolls, quicker acceleration or deceleration and a shorter overall multi-roll line installation, are achieved, leading to less damage and breakage, retained creping and reduced tendency to ply separation. <IMAGE>

Title: Double-acting two stroke I.C. engine
Inventor: MARSH ANDREW DAVID
IPC: F01L23/00
Filed: 1985-11-19
Abstract: A piston (D) is fixed to a piston rod (K) which extends through the centre of each cylinder head (I) to form output shafts. Exhaust valves (G) (R) which are hollow and form part of the piston rod bearings are opened by shoulders (L) (S) on the piston rod (K) and closed by springs (J). Inlet gases are forced into chamber (P) through inlet ports (P) by an external compressor displacing the exhaust gases past the open valve (G). Combustion occurs in chamber (Q) and the piston is forced along the cylinder closing off the inlet ports (E) and allowing the exhaust valve (G) to close. The piston compresses inlet gases in chamber (P) whilst uncovering the inlet ports to chamber (Q). Combustion now occurs in chamber (P). <IMAGE>

Title: Antiskid apparatus for vehicles
Inventor: ADACHI TOSHIHARU
IPC: B60T8/42
Filed: 1986-02-06
Abstract: In a vehicle antiskid apparatus having a master cylinder 2a connected to wheel brake cylinders 21,22,23,24 via respective brake lines 61,62 a pressure regulating valve 56 controlled by master cylinder pressure is provided in a power hydraulic pressure line 65,66 connecting an accumulator 55 with brake pressure modulating valves 58A,58B,58C,58D via directional respective solenoid control valves 57A,57B,57C,57D. The pressure regulating valve 56 is operable, in two modes, in dependence upon master cylinder hydraulic pressure. At higher master cylinder pressures it reduces power hydraulic pressure supplied from the accumulator 55 to a pressure higher by a predetermined amount, than the master cylinder hydraulic pressure, and to deliver this hydraulic pressure to each valve 58A,58B,58C,58D. When the brake is not applied or low master cylinder pressure, the pressure regulating valve 56 cuts off communication between the accumulator 55 and each valve 58A,5818,58C,58D and brings the hydraulic pressure in the pressure lines leading to fluid chambers 58a of the control piston 58f to a value not higher than a set value through the directional control valve 56. Thus, each fluid chamber 58a is supplied with hydraulic pressure reduced to a predetermined value to suppress a pressure change that occurs in the fluid chamber 58a when the apparatus is operated, thereby reducing shock and noise and making it easier to control the operation of the apparatus. <IMAGE>

IPC: F42D1/055
Filed: 1986-06-26
Abstract: A detonator of the type comprising an electrically-fired fusehead in an explosive charge comprises a conditioning means which has two states, normal and armed, and a control means for effecting a change from normal to armed state. The detonator cannot be fired when the conditioning means is in the normal state, and the control means may comprise electronic circuitry for recognising and acting only on appropriate control signals. Accidental and unauthorized firing can thus be eliminated. Other embodiments include an actuator incorporating a delay capable of remote precise calibration and a safety device for reducing still further any risks involved when using these detonators in blasting operations. The detonator is preferably in modular form wherein the coupling together of the detonator, actuator, power unit, etc. forms the necessary electrical connections.
