Patent GB-1097791-A (GB)
Title: Improvements in or relating to q-switched lasers
Inventor: CARMICHAEL CHARLES HALLY HARRO
IPC: H01S3/06
Filed: 1965-01-06
Abstract: 1,097,791. Lasers. MINISTER OF AVIATION, LONDON. Jan. 4, 1966 [Jan. 6, 1965], No. 541/65. Heading H1C. The resonant light path through the active element 1 of a Q-switched laser enters and leaves the element at the Brewster angle, while within the element the path includes a plurality of total internal reflections C, D, E, F at two plane parallel optically flat sides OP, RS of the element. As shown in Fig. 1 the optical cavity is formed by an adjustable mirror 2 and a clockwise-rotating mirror 3. The active element is a neodymium glass rod having sloped and parallel plane end faces OS, PR, the end face PR being so arranged with respect to the rotating mirror 3 that reflected incident light in paths such as HJ pass through the active element and emerge at KL without total internal reflection. Thus Q-switching becomes more effective, since the resonant light path is established suddenly when the light normally emergent at points such as K becomes totally internally reflected at F as mirror 3 rotates. In a modification, Fig. 2 (not shown), the resonant light path enters and leaves the laser active element through angled extensions PQ, TS of the plane parallel and optically flat sides OP, RS.

Abstract: 1,067,443. Circuits employing bi-stable magnetic elements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 10, 1964 [Jan. 7, 1963], No. 706/63. Heading H3B. In a fail safe circuit comprising a plurality of laddies connected in cascade with the output winding of each laddie, except the last, connected to the resetting winding R of the next laddie in sequence, signals are applied first to the input windings I of alternate laddies A1, A2, A3 &c. and then to the input windings of the intervening laddies B1, B2, B3 recurrently so that output signals of the correct polarity are only produced at the last laddie B3 if all control signals are present on the control windings (not shown). The timing of the input and reset pulses is as shown in Fig. 3 and if there is a fault in laddie B1 such that at the termination of the reset signal a spurious output signal is produced which is applied as a reset signal to laddic A2, this signal will occur at the same time as the input signal to laddie A2 and hence will have no effect. Hence no output pulses will appear at the output winding of the final laddic in phase with the input to the last laddic unless all the control coils are energized irrespective of whether or not there are any cracks or other faults in the cores.

Filed: 1955-01-11
Abstract: 785,840. Whaling projectiles. AIR WHALING, Ltd., and BRISTOW, A. E. Jan. 11, 1955, No. 800/55. Class 9(1) A projectile for killing and inflating whales and like purposes comprises a chamber containing a paralysing fluid and a second chamber containing gas together with means operable on penetration of a whale to release the fluid and the gas, whereby the whale is paralysed and inflated. Through the gas chamber 1, which is charged through a valve 2 with an inert gas such as carbon dioxide, extends a tube 3 screwed into a tail support 4 and a guide tube 6. An annular support 9 gripped between the tube 6 and a tapered sleeve 7 supports a fairing 10 having a detachable nose 11. The tail 13 carrying stabilizer fins 16 ends in a clip 14 for attaching the projectile to a spigot gun, a rear fairing 24 being held in position by a collar surrounding the tail. Between the tail 13 and the tube 3 is a firing pin 15 adapted to initiate a slow-burning fuze of a cartridge 32 on firing the gun. The gases from the cartridge drive a piston 19 mounted in a cylinder 17 housed in tube 3 and containing a fluid such as nitrous oxide. Closing the forward end of the cylinder is a cap 18 provided with lugs 20 on which are pivoted two barbs 21. Aligned apertures 22 in the cylinder 17 and cap 18 house the ends of thin-walled tubes 23. During storage, a split pin 26 passing through the nose 11, apertures in channelled members 28 welded to the tube 6 and apertures in the lugs 20, secures the cylinder 17. Before firing, the pin 26 is withdrawn and the nose 11 removed. On firing the pin 15 ignites the fuze to iritiate the cartridge after a given time. The thrust of the gases on the piston drives the cylinder 17 forward until a flange 33 engages a shoulder 34 at the front of the tube 6. Tapered plugs 36 closing apertures in the tube 3 are blown out and gas escapes from the chamber 1 into the tube 3 to impinge on the piston. The tubes 23 being fractured on penetration, the piston drives the fluid through the apertures 22, the fluid being followed by the gas from the chamber. The plugs 36 may be replaced by a slide valve. Specifications 785,431 and 785,432 are referred to.

Abstract: 656,439. Washing and drying machines. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 12, 1949, No. 890. Convention date, Jan. 13, 1948. [Class 138 (ii)] In a clothes washing machine having a spindrying basket 2 in which the clothes are agitated for washing and which is mounted in a tub 1, "suds lock" during the spindrying operation is counteracted by stopping the basket before it reaches its full speed, removing suds by means of a drain pump 6 which operates during the whole spin-drying operation and then re-starting the basket. Washing is carried out by rotary reciprocating type agitator 3. The spinning basket is of the type having slots 4 near its rim which determine the water level 9 during washing and through which water is ejected during drying. When the spin-drying operation is started, water is thrown from the basket and builds up in the bottom of the tub faster than the pump can remove it. When the rotation is stopped the pump removes the excess of water and atmospheric pressure on any suds 10 which have collected during washing operation lowers their level below the bottom of the basket so that when the basket is restarted its rotation is not impeded. Specifications 566,372 and 625,324 are referred to.
