Title: Screw cap for sealed bottles - has internal spiral blade, with inwards curved inner end, breaking and lifting seal
IPC: B65D51/22
Filed: 1986-07-11
Abstract: The cap screws initially onto the neck (4) of a bottle (5) until internal projections (2) snap into a neck groove. A guarantee band (10), once removed permits it to be screwed slightly further to break a diaphragm (6) fixed to the bottle neck. - Tight screwing causes an internal spiral blade projection (12) to cut through the diaphragm seal. The inside end (12') of the blade projection partially lifts the seal by being curved inwards thus allowing the seal to be grasped and removed completely.

Title: Eliminating cyano cpds from gases - by catalytic combustion in presence of oxygen and palladium on alumina catalyst
IPC: B01D53/54
Filed: 1971-10-15
Abstract: Cyano cpds. are removed from gases which may contain other combustible components by passing the gases in the presence of oxygen at a temp. capable of initiating catalytic combustion under practically adiabatic conditions over a catalyst consisting of Al2O3-supported Pd. The gases are passed into the catalyst bed at 150-300 degrees C, and the temp. of the gases inthe catalyst bed is held at 500-700 degrees C by controlling the colorific value of the gases. Esp. useful for treating the waste from the prepn. of acrylonitrile from propylene, ammonia and oxygen. The treatment efficiently and economically converts the waste gases contg. cyano cpds. into a mixt. of nitrogen monoxides, carbon dioxide and water. This mixt. can be passed into the atmosphere.

Abstract: A B S T R A C T           An optical transducer in an avionics system which in-cludes a compass card for indicating aircraft heading has a disc with a cam surface thereon that is rotated by a shaft connected compass card.  When a pilot rotates the heading select indicator associated with the compass card to a new heading, the cam sur-face pivots a shutter in an appropriate direction.  A pair of photoresistors are located in a bridge circuit and are equally illuminated by a corresponding light source when the heading select indicator and the aircraft lubber line coincide thereby effecting a predetermined output from the bridge circuit.  Shut-ter movement, due to a heading or course change, causes either one or the other of the two resistors to have a more or less light impinging thereon thereby producing a bridge error signal.     The error signal output may then be used by a flight director or auto pilot to maneuver the aircraft to the newly selected head-ing.  Once the heading select indicator and the aircraft lubber line are aligned, the shutter is re-located so that the photo-resistors are again in balance and no error signal output ema-nates from the bridge circuit.

Abstract: ABSTRACT OF THE DISCLOSURE           A woven slide fastener and a method of making same. The fastener comprises two fabric supporting tapes, each tape having inner and outer surfaces and having warp and weft threads woven to form a single layer portion and a double-layer edge portion having two overlying arms which merge along a line with each other into a single layer portion of the tape.  Each tape includes a row of linking elements to be coupled by a slide with the linking elements being formed by a meander-shaped con-tinous synthetic warp monofilament bent into a series of U-loops, each loop having two leg portions interconnected by a bent end portion.  The series of U-loops are joined by a leg port on so as to surround an internal space, and the leg portions of each bent end portion lie in a plane disposed normal to the plane of the adjacent U-loop bent end portion and define alternating U-loops disposed on a respective side of the single layer por-tion of the tape and extending parallel thereto for connection to a respective one of the two overlying arms of the weft threads thereof.  The monofilament also defines linking U-loops which constitutes the linking elements and are disposed in a plane per-pendicular to the plane of the single layer portion of the tape and have its leg portions joined to a respective leg portion of an adjacent pair of alternating U-loops.  The linking U-loops are expend along the edge portion of the tape and the point at which the monofilament projects through the fabric of the over lying arms coincides with the line along which the overlying arms of the tape converge.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for automatically compensating brakinq pressure in a failed set of braking members of a system having at least two sets of braking members with each set having two braking circuits through which braking pressure is applied. A single actuating member operates simultaneously on the two cir-cuits of each brake set in response to separate brake pressure detecting apparatus connected to each braking circuit.  In the event of failure in one circuit with subsequent pressure loss, the pressure detecting apparatus of that circuit operates the actuating member to apply a predetermined increased pressure in the operational braking member of the failed set which tends to equalize the braking effect of all sets of braking members.

Granted: 1979-11-13
Abstract: A B S T R A C T        A correction circuit for correcting the frequency of the output pulses produced by a gas flowmeter in dependence on the temperature of the gas comprises a control input for receiving a voltage representative of he difference between the temperature of the gas and a reference temperature.  A voltage-controlled oscillator, operative during fixed short periods initiated by each flowmeter pulse, produces auxiliary pulses at a rate dependent on the voltage at the control input, and the auxiliary pulses are counted in a counter.  Each time the counter counts a predetermined number of auxiliary pulses, it produces a signal which either blocks one flowmeter pulse or adds and additional pulse to the flowmeter pulses, in dependence on the polarity of the temperature difference.

Abstract: ABSTRACT OF THE DISCLOSURE     Disclosed is a control pulse generator for the cyclic generation of a safe sequence of control pulses for purposes of signalling.  A quartz generator actuates a series arrangement consisting of delay elements through a control arrangement which forms a kind of self-holding circuit with time agreement of the duration of the period of the quartz signals with the total delay time of the series arrangement which consists of the sum of the individual delay times of all delay elements of the series arrangement.  The control arrangement consists of a first pulse-edge-controlled D-flip-flop whose timing pulse input is connected to the quartz generator, and which has a direct acting resetting input which is connected to an additional delay element occupying the last place in the series arrangement, in such manner that blocking takes place outside the delay time of the latter delay element. The output of the first D-flip-flop is connected to a dynamic input of a monostable trigger stage, whose initial position output is connected to the timing pulse input of a second pulse-edge-controlled D-flip-flop, of which the D-input is applied to the current output of the said delay element and of which the direct-acting inhibiting input is connected to the quartz generator and of which the initial position output forms the output of the control arrangement.  The delay elements have outputs at which the control pulses sequentially appear.
