Title: Improvements in or relating to the preparation of pharmaceutical and non-palatable products into an easily ingestible form
IPC: A61K9/28
Filed: 1947-12-31
Abstract: A composite ingestible block containing a medicinal ingredient is prepared by heating a sweet substance having a sugar base sufficiently to cause it to melt to a viscous mass, forming successive layers of the viscous mass in a mould and simultaneously sprinkling over the surface of each layer as it is formed a drug in the form of powder, grains, flakes or small pellets before the layer is covered with a succeeding layer, thereby building up a number of layers with the solid drug interspersed between and allowing the whole to set by cooling.

Title: Improved regulating means for pressure-operated electric switches
Filed: 1932-12-13
Abstract: 405,441. Snap-action switches; actuation of switches. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Leonard, V. W.; 81, Vine Street, Saugus, Massachusetts, U.S.A.) Dec. 13, 1932, No. 35342. Convention date, Dec. 16, 1931. [Class 38 (v).] In a pressureoperated snap-action switch for maintaining pressure between two limits, the range of allowable pressure as well as the limits of pressure are varied by adjustments of the spring which opposes the action of the pressure. As shown, the pressure acts through a member 13 upon a diaphragm 12 which is acted upon by a return spring 16. Movement of the diaphragm to the right causes the clockwise rotation about its lower end of a lever 28 connected by a spring 27 to a contact member 25 pivoted at 26, causing the spring to move past the pivot 26 and open the contacts 24, 22. Closure of the contacts is similarly effected by movement of the diaphragm to the left under the action of the spring 16. The pressures at which the switch opens and closes are varied by increasing or decreasing the tension of the spring 16 which is done by rotating a screw 19 which engates a nut 17 which engages the right hand end of the spring. The nut 17, which engages at its periphery the actual turns of the spring, may also be rotated so as to move along the spring and thus vary the number of turns of the coil which are effective. This will vary the extent of the range of allowable pressure.

Title: Improvements in or relating to lubrication of turbo-units
Inventor: DANVERS ELLIS
IPC: F16N7/32
Filed: 1965-08-18
Abstract: 1,102,937. Bearings; lubricating. WESTLAND AIRCRAFT Ltd. 17 Aug., 1966 [18 Aug., 1965], No. 35517/66. Heading F2A. [Also in Division F1] Ball or roller bearings of a turbo-unit are lubricated by means of an oil-mist circulated therethrough by a rotary air-pump, the oil-mist being produced by passage of air over oil deposited on the shaft of the unit. The oilentraining air is returned to the air-pump after having passed through the bearings. In an embodiment, a shaft 4 has two rotary air-pumps 11 mounted thereon, is supplied with lubricant by means of two wicks 10 which lead to an oilsump 9, and is supported by ball-bearings 5 mounted in a carrier 6. The latter is provided with radial fins and is received in a sleeve 7, the radial fins dividing the cylindrical space between the carrier 6 and the sleeve 7 into an even number of longitudinal passages divided into two interdigitated groups allocated respectively to the circulation of air carrying lubricating mist and to cooling air. The oil-mist is passed through longitudinal passages 13, through the bearings 5 and is returned to the passages 13 via circular grooves 16 in endplates 14, 15 and ports 17. Cooling-air is forced through ports 23 into longitudinal passages 24 by a fan 22 mounted on the shaft 4 and enters through ports 25 into an annular space formed between the end-plate 15 and a restrictor-plate 26. The cooling air then escapes through an annular gap 27 formed by the plate 26 and a collar 21 of the shaft 4, and, in escaping causes a back-pressure which is sufficient to prevent leakage of oil through a labyrinth seal 19 provided between the collar 21 and the end-plate 15. In modifications, the wicks 10 may be replaced by small-bore pipes, the circulating air being passed over the ends thereof and a breather arrangement may be provided.

IPC: G11B17/16
Filed: 1966-08-09
Abstract: 1,162,544. Automatic gramophones. J. T. DENNIS. 9 Aug., 1966, No. 35631/66. Heading G5R. A record stack is supported above the turntable by the central spindle and, at the edge of the stack, by a member which is movable to a position at or below the level of the turntable to facilitate manual playing of single records. As shown, the record stack rests on a sensing member 72 and on a shoulder 88 formed in the spindle 70, the bottom record being dislodged by movement of a blade 84 pivoted at 86 in the spindle 70. The sensing member 72 is pivoted at 124 so that its tip 120 may be set to different positions corresponding to records of different diameters, the indexing of the pick-up arm being controlled accordingly by means of a cable 160 (Figs. 12A, 12B, 12C). During each recordchanging cycle the tip 120 of the sensing member 72 is urged inwards towards the spindle 70 and a switching-off cycle is initiated if the movement of the sensing member 72 is not stopped by its encountering a record resting on the spindle. If the sensing member 72 is swung to its lowest position (Fig. 6) it pushes a spring-biased rod 100 clear of the lower end of the spindle 70 which may then be retracted to a position in which only its upper end projects above the turntable 44, for playing single records. The turntable 44 is driven by a concentric lower turntable 42 which is lowered (Figs. 11, 11A) during each record-changing cycle so that the upper turntable 44 is stopped by snubbing blocks 352 (or other stationary surface) while a record is released on to it from the stack. This stopping operation may also be initiated manually at any time. An adaptor for use with records having larger central apertures may be fitted over the spindle 70 (Fig. 10).

Abstract: 1293976 Monitoring pulses J HENGSTLER AG 27 July 1970 [8 Aug 1969] 36267/70 Heading G1U [Also in Divisions G4 and H3] Pulses are monitored to determine whether they are of at least a given duration and have an amplitude within an adjustable range, e.g. to ensure correct operation of a counter receiving the pulses. Pulses produced by contact 1 effect "setting" of a bi-stable circuit 4 in the monitoring arrangement. They are also applied via a counter 3 to a threshold circuit comprising two Zener diodes 8, 6 adjustally biased by a resistor 5 to provide inputs to a gate 7 if the pulses have an amplitude between the threshold values of the diodes. The "setting" of the bi-stable circuit initiates operation of a Miller integrator 10 and if the pulse duration is sufficiently long for the integrator output to reach the threshold of the diode 9 while the voltage from 6 and 8 is still present, the gate 7 is satisfied and the bi-stable circuit and the integrator are reset. If the voltages from 6 and 8 are not still present the integrator output continues to rise until a Zener  diode 11 breaks down and operates a selfholding relay 2 which energizes a lamp 13 and operates a counter 14.

Abstract: 438,558. Fire-extinguishing bombs. FINZI, G., 45A, Via A. de Pretis, Rome. Dec. 21, 1934, No. 36638. [Classes 9 (i), 9 (ii), and 47 (ii)] An automatic extinguisher comprises a frangible container 1, for example, of cardboard, with a predetermined line of fracture, which is suspended from a ceiling or the like by a hook 21. The container is charged with an extinguishing medium and embodies an exposive charge 5 in a frangible tube 2. The latter extends outside the container and has a flange 3 supported on a fusible washer 15, which rests on the flange 14 of a heat-collecting member 13. The latter is fixed to a housing 11 in which is a coiled wire 10, the free end 9 of which is extended through the tube 2 and is operatively connected, as by a coil 8, to the detonator 7 of a fuze 6. In case of fire, the washer 15 melts and the extinguisher falls, uncoiling the wire 10. When the latter is fully extended, the coil 8 explodes the detonator 7, the fuze 6 is ignited, and the charge 5 is fired, scattering the extinguishing medium. Alternative methods of coiling the wire 10 in the housing 11 are described. In place of the fusible washer 15, a release operating by expansion may be employed. A percussion cap may be provided at some point on the container for exploding the charge 5 if the wire 10 should break or the detonator 7 fail to act.
