Vehicle mirror apparatus for viewing crosstraffic at road junctions comprises a pair of rectangular mirrors 2, Figs. 2, 3 and 4, lying back to back with their mirror surfaces facing away from each other, each mirror being pivoted at 4 to a common bracket 6 secured to a U-shaped bracket 8 having arms 10 fixed to a pin 14 rotatably mounted in the top of a casing 16 securable to the bonnet or the rear end of the vehicle, wherein the mirrors can be moved by operating means from their folded positions within the casing to their operative positions in which they are moved out of the casing to positions perpendicular to the casing, so as to be disposed at 90 degrees to each other and each disposed at 45 degrees to the normal direction of movement of the vehicle. A cover 18 for the casing is carried at 20 by the bracket 8 and this moves with the mirrors. A rod 22 is pivotally mounted at one end at 28, relative to the casing, the other end of the rod being pivoted to a link 24 pivoted to the cover at 26. Slidable on the rod 22 is a collar 30 connected by pivotal links 32 with the mirrors and a spring 34 is provided on the rod 22 and secured at its ends to the collar and the link 24. The arrangement is such that when the mirrors are moved out of the casthe rod 22 slides through the bracket 8 and the spring 34 causes the collar 30 to move the links 32 to move the mirrors outwardly relative to each other as shown in Fig. 4. An electric motor fixedly mounted in the casing 16 rotates the pin .14 through a reduction gear as described with reference to Figs. 5 and 6 (not shown). Alternatively the pin 14 may be rotated by a vane in a chamber connectable to the inlet manifold of the vehicle engine as described with reference to Figs. 7. and 8 (not shown) or by means of a bowden cable. The casing may be omitted and the mirrors mounted within a recess in the bonnet. Moreover the casing 16 need not be arranged vertically on the bonnet but at an angle to the vertical in which case the mirrors may be raised to the horizontal position through an angle as small as 45 degrees.

Abstract: 1403484 Radar TELEFUNKEN PATENTVERWERTUNGS GmbH 14 Nov 1962 [29 Nov 1961] 43150/62 Heading H4D In a Doppler radar operated proximity fuse for a projectile, the receiver, transmitter and antenna are mounted in the projectile and operate on at least two frequencies sequentially so as to reduce the effect of interference signals. The transmission frequencies are charged at a predetermined rate and the corresponding receiver amplifier channels are selected in synchronism with the transmission charges. As the projectile approaches the target, the Doppler beat frequency falls while the amplitude increases. Each channel includes a low pass filter to select the required Doppler frequency band and a threshold stage to select the Doppler signal amplitude so as to provide the required distance response of the fuze. Firing occurs only when a coincidence circuit is energized from both channels. In an alternative form, the frequency charges may be effected by a noise source. In a further embodiment, the phase charge which occurs as the Doppler frequency passes through zero provides a third parameter indicating the firing instant.

Title: Process for the preparation of vinyl chloride
Inventor: BRACONIER FREDERIC FRANCOIS AL
IPC: C07C17/08
Filed: 1959-12-18
Abstract: Vinyl chloride is prepared by pyrolysis of a vaporized hydrocarbon by injecting it into a hydrogen-rich gas, quenching the pyrolysis gas to stabilise it, purifying it to remove carbon black, tars, and unsaturated hydrocarbons containing more than two carbon atoms but not hydrogen, nitrogen, carbon monoxide, carbon dioxide and methane, passing the resulting purified acetylene and ethylene-containing gas with hydrogen chloride over mercuric chloride catalyst, separating the vinyl chloride, mixing chlorine with the residual pyrolysis gas over ferric chloride catalyst under the conditions for the synthesis of dichloroethane, separating the dichloroethane, purifying and pyrolising it to give vinyl chloride and hydrogen chloride, the latter being recycled to the first catalysis, the process being carried out under pressure of 8-10 atmospheres. The residual gas after the second catalysis may be used as the source of the hydrogen rich gas specified above. Vinyl chloride produced in the first catalysis may be separated by dissolution in dichloroethane and distilling under reduced pressure in the presence of a polymerization inhibitor e.g. phenol or hydroquinone.  In the example, vaporized naphtha is injected into hot gases at 600 DEG C. under 10 atmospheres and the resulting gas quenched to stabilize the acetylene and purified by (i) oil washing to remove carbon black and tars, (ii) potassium carbonate to remove carbon dioxide and (iii) washing with kerosene to remove the C3 and C4 hydrocarbons. The purified gas and hydrogen chloride are passed over active carbon impregnated with mercuric chloride at 120 DEG C. under 10 atmospheres. The vinyl chloride produced is dissolved in dichloroethane which is subsequently degasified. Chlorine and the residual gas are mixed and passed through a steel tube under 10 atmospheres at 100 DEG C., ferric chloride being produced by the reaction of chlorine with the walls of the tube. The resulting gas is cooled under pressure to give liquid dichloroethane and the residual gas used as the source of hydrogenrich gas.  Dichloroethane is pyrolysed under pressure in the presence of de-ashed activated carbon giving vinyl chloride and hydrogen chloride, which is used in the first catalysis. Ferric chloride catalyst may be impregnated on a carrier e.g. pumice, silica gel, or active carbon.

[Also in Group XIX] A type face, Fig. 1, for recording data to be sensed in a record card machine has raised portions 1 adapted to cause an embossment of the paper in certain areas 5, Fig. 2, of the character as shown in Fig. 3. The characters are printed in magnetic ink and the depressed areas 5 produce a signal appreciably less than the rest of the character owing to their greater separation from the sensing head 6. The paper 4 may be guided over the head by a plate 7. Alternatively the sensing head could be on the reverse side of the paper, the depressed areas 5 then producing a larger signal. In another form the type face may be gapped to produce raised portions which are detected by an increased signal. The characters may otherwise be printed in ordinary ink and the depressed areas detected by a pneumatic sensing head in which changes of clearance between it and the surface of the paper cause changes of pressure which are converted into electric signals.

Abstract: 1511846 Fabricating concrete offshore structures SEVEN SEAS ENG Ltd 7 Oct 1975 [7 Oct 1974 5 April 1975] 43402/74 and 14036/75 Heading E1H [Also in Division B7] A cellular concrete offshore structure is fabricated completely afloat using a raft formed from a plurality of pontoons which have been built ashore previously, the raft having formwork which permits the pouring of concrete to initially build the base of the offshore structure. When the base has been built afloat in relatively shallow water it is towed to a deeper water location where the concrete offshore structure is completed. In one embodiment, each pontoon has a hexagonal deck 10 which is upwardly domed (Fig. 2) and strengthened by radial webs 12. The deck carries internal formwork 11 which gives the pontoon intrinsic buoyancy and the pontoon is stiffened by a framework comprising stanchions 14 horizontal top members 15 and cross braces (not shown) between the stanchions 14. A steel skirt 18 depends from the deck 10 and the under deck space 10A is in communication with a pipe 13. The pontoons which will be on the periphery of the raft each further include an upstanding bulwark member (not shown) so that when the raft is formed by joining the pontoons together it has a continuous bulwark around its periphery which keeps the deck dry and acts as an external formwork. When pouring wet concrete air may be introduced into the spaces 10A to reduce bending moments in the raft. When grounded at its operational site the skirts 18 buckle to accommodate ground irregularities and afford protection against scouring. Water under pressure may be applied to the undersurface of the decks 10 of the raft to facilitate removal of the offshore structure from the seabed.

An electric battery-operated device for use in a toy car simulates either the sound of an internal combustion engine or a car horn as required, and comprises two diaphragms 18, 19 of different diameters at either end of a cylindrical compartment 16 and a striker mechanism adjustable to cause the vibration of one or other of these diaphragms. The motor-striker unit 24 is normally biased towards the larger diaphragm 18 which it strikes with loosely mounted washers 35 to simulate an internal combustion engine, but it may be tilted so that the star wheel 31 vibrates a spring finger (21) and hence the smaller diaphragm (19) to simulate a horn. The tilting of the motor-striker unit (24) is achieved by depressing a knob on the car dashboard which slides rod (51). In a normal engine-noise position, speed control of the striker-unit motor is by a rheostat on the car dashboard, and the motor supply is via contact (41). This control is cut out of circuit when the motor-striker unit is tilted to the horn position, the motor supply being then via contact 42. The batteries can be fitted in a compartment conjoint with that containing the motor unit.
