Each reflecting surface 21 of the first drum comprises a pair of orthogonal reflecting members 21A, 21B in which the line of intersection 21C of the members is perpendicular to the first axis 23, and the axis 22 of the second drum is displaced, less than its radius, from the plane containing the first axis 23 of the axis 29 of the focusing system, so that radiation entering along axis 29 is not obscured from the detector by the second drum. System 10 focuses radiation onto the surface of drum 25 and lens system 30 refocuses radiation into the detector 13 by way of a stationary mirror (31, Fig. 2 not shown). A second component of scan may be introduced by offsetting adjacent lines 21C in a direction parallel with the axis of rotation. In a second embodiment (Fig. 3-5 not shown) detector 13 is on the far side of the first drum from the focusing system 10 and an interceptor (40), driven synchronously by a gear train with drums 20 and 25, provides reference signals. In a third embodiment (Figs. 6, 7 not shown) the reflecting surfaces 21 are circumferentially spaced and the whole apparatus is mounted in a casing having an aperture for receiving radiation.

Filed: 1973-11-07
Abstract: 1423789 Tracheal devices LANZ MEDICAL PRODUCTS CO- 7 Nov 1973 [8 Nov 1972] 51609/73 Headings A5R and A5T [Also in Division F2]  A tracheal device comprises a tracheal tube 1 having a cuff 3 able to be inflated through a tubule 5 via a valve in a housing 7 and a balloon 25, by a syringe applied to the valve, and is provided with a check valve in a passage between the tubule 5 and the balloon 25 which restricts the flow of air from the cuff to the balloon so that, should a respirator connected to the tube 1 provide a sudden high pressure in the patient's air-way, air is not forced out of the cuff. As shown, the valve in the housing 7 comprises a rubber tube 13 in a bore 9 and a pin 16 which, when the syringe is applied to the valve housing, is moved by the syringe nozzle towards the balloon causing the tube 13 to stretch and decrease in diameter. Air can then be pumped from the syringe down the bore 9 around the tube 13, into a passage 27, and then via passage 24 and tube 12, into the balloon and tubule 5. On removing the syringe from the valve housing, the tube 13 regains its normal shape and the valve closes. With the valve closed, air may pass from the balloon 25 to the tubule 5 and cuff 3 through the check valve which comprises a flexible band 30 acting as a one way valve in a by-pass passage 27. 28 connecting the tube 12 and the passage 24. The flexible band 30 is said to be a loose fit against the base of the by-pass passage 28 so that air can in fact leak back slowly from the cuff to the balloon. In a modification it is stated that the check valve band 30 may be integral with the neck of the balloon. The balloon is said to be of a type which expands to a size at which air pressure in the balloon is the same as the maximum air pressure desired in the cuff after which the balloon will expand further without increasing that maximum pressure as additional air is forced into it. This prevents the cuff being over-inflated.

Abstract: 1386780 Pressure die casting machines BNF METALS TECHNOLOGY CENTRE 14 Dec 1972 [17 Nov 1971] 53420/71 Heading B3F [Also in Division B5] In a pressure die casting process in which molten metal is forced into the die cavity through a closed duct by applying pressure to the metal in the duct. the temperature of the cast metal is sensed and the said pressure maintained until the said temperature falls below a predetermined value. The said pressure is then reduced and the still molten metal in the duct withdrawn therealong, the dies being opened during this withdrawal. In the embodiment shown, the metal is forced into the die by a plunger 45 which is held in its down position until the temperature sensed by a thermocouple 14 falls below a predetermined value. The plunger is then moved upwards thus drawing the molten metal remaining in the gooseneck 43 away from the dies 10 and 12. Before the plunger 45 uncovers the port 49 for allowing the metal to flow into the pump 42, a contact 51 carried by the plunger 45 engages a fixed contact 52 and initiates the opening of the dies. Alternatively, the dies may be opened by allowing a very short time delay after the commencement of the plunger withdrawal and then causing a signal from the temperature sensor to initiate the die opening sequence directly. The electrical circuit for controlling the operation of the machine is such that commencement of the plunger withdrawal can only take place if the temperature sensed by the thermocouple 14 first rises above and then falls below the said predetermined value. Alternatively, a timing device 15 may be used to prevent the temperature sensor from operating prematurely. Reference has been directed by the Comptroller to Specification 1,288,037.

Abstract: 1438929 Tightening seat belts SOC NATIONALE DES POUDRES ET EXPLOSIFS 12 Dec 1974 [20 Dec 1973] 53859/74 Heading A3V [Also in Division F2] A seat belt is tightened by a piston moved within a cylinder by release of high pressure gas triggered by an impact detector. At a predetermined stress a link between belt and piston fractures and activates a jamming mechanism preventing further advance of the piston. Forward movement of the wearer is damped as the gas is compressed by return of the piston. The belt is attached to the inner part 14 of a buckle, fixed to the inner member 15 of a rod 3. Outer part 17 of the buckle is fixed to an outer member 20. The head 61 of the inner member includes an easily fractured neck 62, and abuts the end of the outer member 20. The end of the rod 3 is attached to a piston, generally indicated by 7 movable within a cylinder 8 held in casing 5 by a frangible screw 10a. Ignitable pyrotechnic charges 11 are housed in damping chamber 23, which communicates via parts 50 with expansion chamber 23.  When the charges are ignited piston 7 is driven to the right, tightening the belt, until neck 62 fractures. Further movement of the piston in that direction is then prevented. In the embodiment shown, head 61 is projected by spring 63 and forces rods 60 radially outwards. A ring 59 thereby jams balls 58 be tween conical surface 64 of the piston and the inner surface of the cylinder 8. In a modifications (Figures 7, 8 not shown) the ring is moved by pivoted levers (74), or pressure of the gas passing through the fractured head and passages (88, 92-94) in the piston. Continued forward movement of the wearer against the belt withdraws the piston to its initial position. Fracture of screw 10a releases the cylinder 8 so the damping is continued as gas is compressed in chamber 23. The chamber vents via valve 28 at a predetermined pressure. In a modification (Figure 7 not shown) cylinder 8 moves in an outer cylinder (8a) which is released to prolong damping when a retaining ring (66) fractures. Figure 8 (not shown) shows a residual damping chamber (77) replacing the valve.

Abstract: 1417858 Leader gear systems EATON CORP 22 Nov 1972 [23 Nov 1971] 53897/72 Heading H4U [Also in Division B7] Apparatus for controlling a vehicle comprises two parallel conductors defining a first portion of a vehicle guide path and carrying alternating current at the same frequency but differing in phase, the resultant magnetic field having an effective phase differing from that of the magnetic field set up in either conductor alone, the conductors separating at a point of divergence to define separate guide paths, a sensor on the vehicle, a phase-responsive circuit receiving signals from the sensor to provide signals to control the vehicle steering and means for selectively controlling the phase-responsive circuit to provide an output responsive principally to one or other of the conductors at the point of divergence so that the vehicle tracks one selected conductor. As described, the currents energizing the two conductors are in quadrature and the effective phase leads the phase of one conductor and lags the phase of the other by 45 degrees. The sensor comprises a pair of orthogonally related coils providing a reference phase and a sense phase respectively, to control the steering and the means for controlling the phase-responsive circuit includes means for advancing or retarding the reference phase by 45 degrees. The two conductors 8, 9, may be arranged in the manner shown in Fig. 6 to provide code signals along the guide path in the form of half circular loops, each such loop having a phase representing binary 1 or binary 0 as required, the sensor being responsive to such signals to operate selected controls such as speed, hooter &c., or turn on or off an ultrasonic radar detector. The phase of the signal carried by the conductors may be changed from a central station by the same amount in each conductor so that their relative phase is unaffected to provide further code signals without affecting the steering. An off-path detector stops the vehicle if the received signal strength is so low as to indicate that the vehicle is off the guide path. Path selection may be effected by an on-board stored programme or by a command signal from the central station in combination with distance measuring means on the vehicle.
