Title: Dynamic magnetic memory transducer positioning apparatus
IPC: G11B5/60
Filed: 1966-06-07
Abstract: 1,121,404. Recording and playback. GENERAL PRECISION SYSTEMS Inc. 7 June, 1966 [22 Oct., 1965], No. 25377/66. Heading G5R. In a data storage and retrieval system, the transducers are biased towards the record surfaoe by a first spring arrangement, which is coupled to a second spring arrangement exerting sufficient force to overcome that exerted by the first on the transducer and hold it normally withdrawn. An actuating system is energizable to release the force exerted by the second arrangement in two stages, the head being lightly urged toward the record in the first stage, and strongly biased toward it in the second. The system is used in a disc type store, where the heads must be retracted from the discs so that the head assemblies may be removed for repair etc., are positioned fairly close while the discs are run up to full speed and very close when this speed is attained. The plates 30 on which the head assemblies 92 (Fig. 3) are mounted have channels 54 therein for guide tubes 58. Over the tubes is a spring metal plate 66 secured at one end 76 but movable against its spring force at the other end 65 relative to a bolt 78. The heads 94 are supported on a leaf spring assembly 90 which normally urges them towards the recording discs but is held back by the arm 66a on the spring plate 66. When nitrogen at a given pressure is pumped into the tubes 58, the spring 66 is pushed up a small amount and the beads are urged lightly towards the discs under the action of the spring 90, which is released, to a suitable position for the running up of the discs to their operating speed. When this speed is reached further pressure is applied, and a second spring 96 is released to force the heads into close contact with the disc.

Title: Improvements in apparatus for recording and repeating telephone messages
IPC: H04M1/65
Filed: 1960-07-21
Abstract: 923,597. Substation equipment. J. FEAT. July 21, 1960 [July 23, 1959; July 11, 1960], No. 25494/60. Class 40 (4). [Also in Group XXXVIII] In a magnetic drum type recording and playback apparatus for a substation, the actions of record, off and playback via the telephone receiver are controlled by a single switch while a pointer rigidly attached to a combined record playback head indicates the amount of unused drum remaining. The normal baseplate of a desk set is replaced by the base 2 (Fig. 2), contact plates 3, 4 being connected to line and plate 5 to the normal cradle switch, a spring-loaded flap 7 connecting plates 3 and 5 together when the set is not placed on the recorder. Flexibly mounted plates 15, 16 and 17 co-operate with plates 3, 4, 5 respectively under the influence of magnets 6 and 21. With key 47 in the recording position, thus lighting indicator lamp 13a, ringing current pulls up relay 24 (Fig. 3) which closes circuits for a motor 31 and a power supply unit 26, consequently spindle 34 starts to rotate and an R-C coupled transistor amplifier 30 is energized. Arm 42 (Figs. 10, 11, not shown) of a function switch 38 (Fig. 7, not shown) begins to rotate in the direction of the arrow (Fig. 3) and a contact staple 41 bridges a first pair of conducting tracks 40 so energizing a vibrator 25 in place of the normal bell set. Upon the bridging of the next two pairs of conducting tracks, the output signal from a reading head 43, which scans a magnetic track 39 containing a prerecorded message is applied via a conducting band 44 and spring 45 to the amplifier 30 and hence to the calling subscriber. Finally, arm 42 is restrained by a stop 42a and it slips on spindle 34 whilst closing suitable circuits for the recording of a message on drum 35. A raised thread 36 on this drum serves to guide recording playback head 57 which is connected to an erasing head 62 although both heads can rotate independently about an earthed guide bar 53. When the caller replaces his receiver, relay 24 falls back, the power supply and motor are cut-off and arm 42 returns to its initial position under spring action. If the recording head reaches the end of the drum then a set of contacts 63 are operated and no further calls can be recorded until the drum is reset. When key 47 is placed in the neutral position, heads 57 and 62 are lifted off the drum by the action of rod 56 and are returned by spring pressure to their initial position. Moving key 47 to the playback position causes stud 50 to ride up face 51b of frame 52 and consequently rod 56 is rotated slightly with respect to rod 53 which is fixed rigidly to the chassis 22, thus allowing playback head 57 to rest upon the drum but preventing erasing head 62 from doing so. At the same time switch wafers are operated so that the telephone earpiece can act as an output transducer. The recorder may be powered by batteries and the motor may be a clockwork one which is provided with an electrically triggered start and stop device.

Title: Improvements in the manufacture and production of amines
IPC: C07C209/64
Filed: 1933-09-18
Abstract: Secondary amines are converted into primary amines by reaction with ammonia at a raised temperature in the presence of a dehydrating catalyst.  Under the same conditions, tertiary amines are converted into primary or secondary amines by reaction with ammonia or a primary amine or a mixture thereof.  The reactions are preferably affected at 300--500 DEG  C. in the vapour phase and at a raised pressure.  Suitable catalysts are alumina, thoria, titanium dioxide, silica, kaolin, aluminium phosphate, oxides of tungsten and molybdenum, and active charcoal; metallic catalysts may also be used, but are less suitable.  A small proportion of an alcohol or phenol may be present in the reaction mixture.  In the examples: (1) trimethylamine and ammonia are passed at 380 DEG  C. and 150 atm. pressure over alumina gel; a mixture of mono-, di- and tri-methylamines is obtained, and is separated by fractional distillation; (2) triethylamine and ammonia are passed at 390 DEG  C. and 200 atm. pressure over alumina gel; the mixture of mono-, di- and tri-ethylamines obtained is separated by fractional distillation, first under pressure and then at atmospheric pressure; (3) N-dimethylaniline and ammonia are led at 400 DEG  C. and 200 atm. pressure over alumina gel; a mixture of aniline with N-mono- and -di-methylaniline is obtained; (4) as in example (1), except that the reaction is effected at 390 DEG  C. and atmospheric pressure; (5) dioctadecylamine and ammonia are led at 380 DEG  C. and 200 atm. pressure over alumina gel and kaolin; a mixture of mono- and dioctadecylamines is obtained; (6) aniline and trimethylamine are passed at 380 DEG  C. and 100 atm. pressure over aluminium oxide; mono- and dimethylamine and mono- and di-methylaniline are produced.

Filed: 1927-09-29
Abstract: 303,199. Thorp, F., Butterworth, E., and Rotary Meter Co., Ltd. Sept. 29, 1927. Gas meters.-Delivery and exhaust of gas to and from the metering chambers is controlled by a rotary piston-type valve rotated constantly in one direction. The invention is described in connection with the balanced-bell meter of Specification 299,935, but is applicable to other types, including dry diaphragm meters. The substantially cylindrical valve is divided by a diametrical partition a into two reversely-situated halves each closed at one end (b or c) and open at the other and the gas supply o is at one end of the barrel and the exhaust q at the other end so that onehalf n is always in communication with supply and the other half p with exhaust. A peripheral gap (d or e) in each half affords access to the ports which are arranged diametrically opposite in pairs, the one pair g, g<1> being laterally displaced with respect to the other. In operation, the ports f<1>, g<1> on one side and f, g on the other are alternately supply and exhaust ports and the relative angular displacement of the pairs f, f<1> and g, g<1>-as shown 90‹-results in a phase difference in the movements of the two pairs of measuring bells which are connected with the valve by connecting rods and cranks. The valve and its casing may be slightly tapered and the valve capable of axial adjustment such that there is no actual contact, a liquid film being relied on to ensure tightness. To reduce friction further the valve spindle runs in ball bearings.

Filed: 1928-07-02
Abstract: 305,271. Heffernan, B. July 2, 1928. Fluid-pressure; hand and foot actuation.- In a motor vehicle in which the brakes are applied by engine suction and additional fuel is automatically supplied to the engine during the braking operation an automatic valve is provided adapted to shut off the supply of additional fuel after a predetermined quantity has been supplied. The brakes on the four wheels of the vehicle are applied with equal pressure by vacuum cylinders f on each side of the vehicle each containing two pistons connected to the brakes by cables b. The centres of the cylinders are connected by a pipe e which is connected to a valve d adapted to connect the pipe e to an atmospheric port s, Fig. 3, or on movement of connected pistons m by the foot pedal to cover the port s and connect a port n in the induction manifold of the vehicle engine to the pipe e. The pistons are maintained with the pipe e open to atmosphere by a spring. The valve casing is connected to a pipe p to a chamber filled with petrol from the carburettor float chamber through a non-return valve r, so that an additional supply of petrol to the engine is ensured when the brakes are applied until the automatic ball valve t seats at the upper part of the chamber and stops this supply. The ball t is poised on the end of a spindle which is manually-adjustable. The valve pistons are operated by means of a lever c<1> pivoted on a curved lever c<11> through a slot in which the lever c<1> passes so that the brakes can be applied directly by a cable b<1> when the lever c<1> is moved to the end of the slot. Lubricators k may be supplied on the pipe e or on the vacuum cylinders. A flexible conical cover g prevents access of dirt &c. to the brake cylinders.

Abstract: 1,129,185. Waveguide filters. STANDARD TELEPHONES & CABLES Ltd. 10 June, 1966, No. 25966/66. Heading H1W. A band-pass filter for H-mode waveguides comprises a length of waveguide, Àe.g. rectangular waveguide, which is dimensioned below cut-off such that it supports only evanescent waves and means for terminating the length in a capacitative reactance which at a chosen centre frequency is the conjugate of the positive imaginary characteristic impedance of the length of waveguide. The specification explains the theory of such filters and shows that the band-pass limits are given by where the symbols have their usual meanings. The centre frequency is given by f 0  = #f 1 f 2 . Fig. 1 shows a three-section filter in which the capacitances are provided by screws 4. In a modification of this construction (Fig. 6, not shown), the capacitances, are provided by transverse ridges. In a modified method of realization (Fig. 7, not shown), the capacitance is provided by an appropriate length (11) of short-circuited standard (propagating) waveguide joined to the end of the length (10) of cut-off waveguide. The filter section thus formed is coupled to a standard dominant mode waveguide as a shunt or series stub (Figs. 9, 10, not shown).
