Title: Improvements in or relating to homing systems
Inventor: BEDFORD ALAN
IPC: F41G7/22
Filed: 1963-03-22
Abstract: 1,116,801. Photo-electric position control. DE HAVILLAND AIRCRAFT CO. Ltd. 23 March, 1964 [22 March, 1963], No. 11570/63. Heading H4D. [Also in Division G3] A missile is guided towards a target by radio signals from a separate command centre. The missile carries a fixed T.V. camera which transmits, to the centre, signals corresponding to the target angular position relative to the missile longitudinal axis. In one embodiment, a signal is also transmitted from the missile corresponding to the missile angular position relative to the axis of a gyroscope mounted in the missile. Control signals from the centre process the gyro until the two sets of signals from the missile are equal. The gyroscope axis then lies along the sight line and the operator at the centre maintains this condition by further precession of the gyroscope. The precession rate control signal is simultaneously applied to the missile control system to navigate it to the target. In a second embodiment, the gyroscope is omitted and the target image, at the command centre, is maintained by the operator within a movable graticule. The signals controlling the graticule are also transmitted to the missile to manoeuvre it to the target.

Title: Improvements in or relating to sound recording medium
Filed: 1949-05-02
Abstract: 681,992. Gramophone records. DICTAPHONE CORPORATION. May 2, 1949 [May 15, 1948], No. 11635/49. Class 40 (ii). A sound-recording composition consists of a sound-recording wax containing up to 10 per cent. by weight of N-cyclohexyl lactamide. Wax soundrecording cylinders, discs or other blanks may be prepared by adding the lactamide to the wax while the latter is in a molten condition prior to being cooled and cast to desired shape. Conveniently however, the lactamide is formed in situ in the wax by adding cyclohexylamine lactate to the wax in amount up to 10 per cent. by weight, heating the mixture of wax and lactate to convert the lactate into the lactamide and then cooling and casting. The lactamide serves as an anti-static agent which prevents adhesion of chips to the blank during recording. In an example, a.molten mixture is prepared consisting of stearic acid neutralized by caustic soda, red lead, paraffin wax, myrtle wax and cyclohexylamine lactate, the mass is heated for 24 hrs. at about 375‹ F, during which the lactate is converted into the lactamide, and then the mass is cast into cylinders. It is stated that the lactate may be prepared as described in Specification 682,058, [Group IV(b)]. The Specificaton as open to inspection under Sect. 91, is not restricted to the above specified amounts of the lactamide or lactate. This subjectmatter does not appear in the Specification' as accepted.

Title: Variable pitch fans or propellers particularly for gas turbine engines
IPC: F01D7/00
Filed: 1971-04-27
Abstract: 1371371 Propellers DEFENCE SECRETARY OF STATE FOR 27 April 1972 [27 April 1971] 11728/71 Heading B7V [Also in Division F1] A variable pitch fan or propeller comprises a rotor mounted for rotation about a main axis and on which blades are mounted for rotation about their longitudinal axes to vary their pitch, there being provided in association with each blade a cam member, a cam following member and a reaction means, one of the members being connected to the blade to rotate therewith about the longitudinal axis thereof, one of the members being radially movable under centrifugal force due to rotation of the rotor about the main axis, and the cam member being profiled and co-operating with the cam following member and reaction means so as to provide a turning moment on the blade derived from the centrifugal force on the movable member to substantially balance or more than balance the centrifugal turning moment of the blade. The ducted fan of a gas turbine engine comprises blades 2 which are varied in pitch by means of a vane-type hydraulic actuator 10 acting through bevel gearing 15, 16, 17. Each blade root 5 is surrounded by a cylinder 21 which is attached to the root and a cylinder 20 which is attached to the outer wall 9 of the fan motor. Three pins 33 carried by a cage 36 each carry rollers 35 which engage complementary cam slots in the cylinders  20, 21. Centrifugal force causes the rollers to react against the cam slots in the cylinder 20 and act on the cam slots in the cylinder 21 to provide a turning moment about the longitudinal axis 6 of the blade 2 which opposes the centrifugal turning moment inherent in the blade and tending to turn it into fine pitch. The turning moment produced by the cam tracks may counterbalance the centrifugal moment or may also counterbalance the gas turning moment on the blade. There may be a net turning moment tending to feather the blade in the event of failure in the pitch control mechanism.

Title: Preparation of ª‰ª‰ª‰-trichlor-ª‡ª‡-bis 4-chlorphenylethane or ºÔºÔc-dihlordiphenyltrichlorethane
IPC: C07C17/26
Filed: 1944-06-21
Abstract: Dichlorodiphenyltrichloroethane is prepared by reacting chloral or chloral hydrate with monochlorbenzene in the presence of concentrated sulphuric acid and preferably oleum, as condensing agent, in which an excess of about 25-75 per cent by weight of monochlorbenzene is used above that required stoichiometrically. In one method, an excess of about 50-75 per cent by weight of monochlorbenzene is used and the condensation product, a solid, is separated from the mother liquor by filtration.  Another method consists in using a 25-50 per cent excess and sulphonating the unreacted monochlorbenzene by the further addition of concentrated sulphuric acid or oleum.  Preferably, pure chloral hydrate is used, but anhydrous chloral of 90 per cent purity gives useful results.  In examples: (1) 105 grams of chloral hydrate are mixed with 200 mls. of monochlorbenzene at 0 DEG  C. and 220 mls. of oleum added over 7 to 8 hours followed by stirring for a further 3 to 4 hours when the condensation product may be filtered from spent acid and unreacted monochlorbenzene; using 350 mls. of monochlorbenzene, separation by filtration is not possible; (2) 105 grams chloral hydrate and 170 mls. monochlorbenzene are similarly reacted with 220 mls. of 20 per cent oleum at 20 DEG  C., the reaction mass crystallises and is then stirred while 160 mls. of additional oleum are added over a period of one hour, whereupon the mixture may be filtered and the solid product washed and dried. Specification 547,871 is referred to.

Title: Improvements in or relating to loading apparatus for ordnance
IPC: F41A9/42
Filed: 1952-05-09
Abstract: 732,789. Loading apparatus for ordnance. MOLINS, D. W., MASON, J. A., and MOLINS MACHINE CO., Ltd. Aug. 7, 1953 [May 9, 1952], No. 11865/52. Class 92(1). A loading tray 1 comprises a movable part 1B whereby the interior size of the tray may be altered to accommodate either a projectile or a charge. In the construction shown the tray is mounted on a bracket 2, Fig. 1, which can swing about bearings on the recuperator casing 3 to move the tray from the position shown to a position in line with the breech 5. The part 1B is pivoted at 6 to the main tray part 1A and can move from the full-line position, when the tray as a whole is of a size to receive the charge, to the chainline position, when a narrower trough-like tray is formed to receive the projectile. The movements of the part 1B are automatically effected during the swinging movements of the tray, and for this purpose the pivot 6 carries an arm 7 connected by a link 8 to a lever 9 fixed to a lever 11, the latter engaging a cam whose axis coincides with that of the bracket 2; a spring 14 tends to keep the part 1B in the full-line position. A pawl 18 serves to move the cam only when the bracket rotates clockwise, and the cam is suitably designed to effect suitable movements of the part 1B so that it assumes one position when the projectile is loaded and the other position during its subsequent clockwise movement when it carries the charge.  Ramming. The projectile and charge are rammed by pushers 30, 31, Figs. 2 and 9, on chains 36, 37, which pass around twin sprockets 34, 35 journalled at the ends of the main tray part 1A. The chains are driven by an electric motor 100 via flexible shaft 39 and gears 40, 41, 42, 43, and complete-their ramming stroke when abutments 45 thereon engage a stop 44, the motor then being driven in reverse. The pusher 31 projects through a slot 38 in the tray. The pusher 30 engages a block 247 on a bar 47 which is mounted on rollers 48 in a guide 46 in the tray, and on the block is pivotally mounted a long rammer bar 53. In use the placing of the projectile or charge in the tray depresses the bar 53 until they have been moved forward by the pusher 31 ; thereafter the bar rises under the actions of a spring 54 and a link 61, which is connected via a pivot 57 to the bar and rides up an incline, and under the influence of the pusher 30 completes the ramming movement. The ramming of the projectile is facilitated by the provision of a guide tray device similar to that disclosed in Specification 703,319, but modified to ensure that the tray is moved into the breech chamber only for the first of each two tray swings. Fig. 17 (not shown), gives the electric circuit employed to move the parts in the appropriate timed sequence.

Title: Signalling in telephone systems
IPC: H04Q1/442
Filed: 1955-04-26
Abstract: 768,917. Automatic exchange systems. SKILLMAN & CO., PTY., Ltd., T. S. April 26, 1955 [June 10, 1954], No. 12033/55. Class 40 (4). In a system in which signalling is effected by raising the level of an alternating current to one approximately equal to that of average speech currents, filter means are provided to separate the signalling and speech currents, said filter means being inadequate to reduce peak speech currents to below the operate level of the receiver which is therefore provided with delay means to prevent spurious operation by such peaks. The invention as described is applied to the reversion of the called party answer signal. As shown, an outgoing circuit OE is connected to an incoming circuit IE over a carrier circuit of the usual type. On completion of a calling loop, relay A operates B and DB, DA follow, but the latter shortcircuits DB which releases again. Relay A operates OHS which injects tone into the modulator OM. After demodulation at IDM in the incoming circuit the tone is filtered out at IHF and operates the receiver ISR to bring up relay IHR. The latter operatse HH and M follows. Relay HH completes a calling loop to an operator's position or to an automatic exchange. In the latter case dialled impulses are repeated by A, OHS, IHR and HH, relay N coming up during the train to provide resistive loop to the exchange. When the called party answers, battery reversal over IE operates F and IHS follows to revert tone over the carrier link. In the outgoing circuit the tone is separated by filter OHF to operate relay OHR. The latter short-circuits DA which releases slowly, permitting DB to operate and release DD which reverses the polarity over OE as an answering signal. A backward clear releases OHR and DA operates to release DB by short circuiting. DB re-operates DD. The release and operate times of DA, DB, DD may be so arranged that DD may faithfully repeat backward impulses of prescribed duration, e.g. multi-metering pulses. False operation by speech or like peaks breaking through filter OHF is prevented by the slow release trains of DA and DD. The tone used may be the carrier frequency itself.
