Title: Rotary differential rotor IC engine - has twin rotors hydraulically controlled by eccentrics to allow compression and expansion of air
IPC: F02B55/14
Filed: 1975-06-24
Abstract: The rotary i.c. engine has two rotors mounted on a common shaft (1) and connected by differential bevel gears (19, 24, 25) to a common output gear (27). The pistons (5, 8) are rectangular blocks which are attached to each of the rotors (2, 3) and overhang the other rotor (3, 2) and at the same time form a partition in the annular space between the rotors (2, 3) and casing (12). Eccentrics (15, 20) driven by the rotors (2, 3) are connected to hydraulic pistons and arranged so that either rotor can be held stationary whilst the other rotates. This allows alternate compression and expansion to occur between consecutive pistons (5, 8) so that all the phases of the engine's working cycle are carried out.

Title: Guided vehicle tyre deflation detector - has strain gauges on track and threshold comparator to set-off alarm
IPC: G01L17/00
Filed: 1975-09-04
Abstract: A vehicle tyre deflation detector is used to detect when the load applied by the wheel has changed. It is used as a safety device.

Title: Isocyanate prepn. by phos:genation of amines - contacting reactants as concentric streams
Inventor: IBEN HANS
IPC: C07C263/10
Filed: 1976-09-21
Abstract: Amines are converted into mono-, di- and polyisocyanates by phosgenation under pressure and at high temps. in the presence of one and the same solvent. The process comprises feeding to a reactor an annular stream of an amine-monochlorobenzene mixt. inside and around which concentric streams of a phosgene-monochlorobenzene are respectively allowed to flow. Phosgenation is accelerated with reduced formation of by-prods. e.g. polyurea. The tubular reactor can therefore be operated during longer periods than in prior art reactors (e.g. for 6 days instead of =3 days).

Title: Arc welding current source - with smoothed direct current feeding thyristor bridge for square wave alternating current arc welding
IPC: B23K9/10
Filed: 1976-10-20
Abstract: Welding current source for alternative d.c. welding (heavy metals) and a.c. welding (light metals) uses a rectangular wave form for the latter. This is produced by a bridge circuit, fed by a d.c. source, which includes four thyristors in pairs of two. A firing circuit controls the thyristor pairs which are connected with the anode of one pair to the positive pole and with the cathode of the second pair to the negative pole of the d.c. source. This requires no stabilizing high-frequency pulse generator for igniting the half waves in a.c. welding. A smooth shape of the direct current is combined with a steep zero passage for a.c. welding so that excellent stability is combined with good quality welds in both cases.

Title: Aircraft nut and bolt assembly system - detects alteration in distance between datum points on nut when tightening
IPC: B25B23/147
Filed: 1977-04-27
Abstract: The nut and bolt assembly system is for use with a load-indicating nut ensuring that the bolt has been pulled down to the correct degree. A tightening torque is applied to the nut simultaneously with a detector for the alteration in distance between two datum points on the nut body. Torque continues to be exerted until the detector has reacted to an alteration of a predetermined value in the distance concerned, and which in turn can be arranged to initiate a visual or audible signal. Where a power-operated spanner is used, the signal can cut off the power to it.

Title: Digital receiver evaluator measuring reception quality - subjects demodulator or comparator to perturbation and obtains pseudo-error rate at adder output
IPC: H04B17/40
Filed: 1977-12-05
Abstract: The evaluator measures the quality of reception of a regenerator's receiver in a digital communications link or of a digital receiver by using a corrective demodulator or comparator and an auxiliary demodulator or comparator functioning in a perturbation mode. A pseudo error is obtained at the output of a modulo 2 adder whose inputs are connected to the outputs of the demodulators or comparators. The level of perturbation to which the auxiliary demodulator or comparator is subjected is controlled such that a constant pseudo error rate is obtained at the output of the adder. The value of this level of perturbation determines the quality of reception.

Title: Storm-water overflow channel for inlet to sewage works - has adjustable weir, outlet of which comprises circular aperture cut in thin cross=wall
IPC: E03F5/10
Filed: 1978-06-22
Abstract: Installation comprises open rectangular channel with a storm water overflow weir and a circular outlet aperture which is formed in a relatively thin cross-wall. This type of aperture is less sensitive to variations in impounded depths (i.e. through flow is a function of the root of the impounded depth) thus, promoting uniform feed to purificn. works. The weir is adjustable, being in the form of a slidable plate; and the outlet aperture discharges into a transition chamber. The downstream wall of the main channel may include U-notch for flow measurement, a shutter being used to bring either the V-notch or the aperture into use. The thickness of the downsteam wall may be less than one quarter of the aperture dia.
