Title: Improvements in or relating to magnetic azimuthal direction-indicating apparatus
IPC: G01C17/30
Filed: 1946-03-12
Abstract: 624,083. Earth inductor compasses. HINE, A., and HITCHINS, H. L. March 12, 1946, No. 7764. [Class 37] [Also in Group XX] A magnetic compass provided with means for generating a magnetic field or fields to neutralize the effects of the vertical component of the earth's magnetic field is characterised in that the intensity of the neutralizing field or fields is controlled by the output of a normally vertical saturable inductor detector element. In the saturable inductor shown, Fig. 1, installed, for example, in an aircraft, the required compensating field is derived from an energized coil c gimballed and weighted so that it is maintained horizontal and freely surrounding two detector elements a, b fixedly mounted fore and aft and athwartships respectively. A third vertical detector f secured to the craft develops an output E.M.F. responsively to the influence of the vertical component of the earth's magnetic field and this is applied as shown, Fig. 2, through an amplifier-rectifier g to energize the coil c; the output from g is preferably fed back through an additional winding on the detector f in series with the coil c. The current through the coil c as it is the result of an E.M.F. generated in detector f varies automatically as the detector E.M.F. changes with change in terrestrial position of the compass. The detector f may be arranged to swing freely with the gimballed coil c. In a modification, Fig. 5 (not shown), the compensation is effected by means of coils wound directly on the detectors a, b and connected respectively to separate sine potentiometers fed by the circuit f, g and co-operating with a gimballed vertical gyro or a gimballed pendulum, Figs. 3 and 4 (not shown). As applied in a saturable inductor, Fig. 6, having a single rotary detector o maintained constantly E-W, the compensating field is produced by fixed radial coils p<SP>1</SP>, p<SP>2</SP>, q<SP>1</SP>, q<SP>2</SP> with sine potentiometer gyroscope control similarly to Figs. 4 and 5. The radial coils may be omitted and a single neutralizing coil wound directly on the E-W detector, Fig. 7 (not shown), and supplied with current from a sine potentiometer controlled by the E-W tilting gimbal element of a pendulum or vertical gyro, the actuating gimbal axis of which is maintained constantly N-S. Three or more detectors may be suitably arranged to supersede the pair of detectors a, b of Fig. 1 and the single detector o in Fig. 6 or a gimballed neutralizing coil c as in Fig. 1 may surround the single detector o. Drawings accompanying the Provisional Specification, Figs. 1 and 2 (not shown), illustrate the enclosure of a construction similar to Fig. 1 in a bowl containing an oscillationdamping liquid.

Title: Improvements in or relating to protective devices for reducing risk of seizing-up inhydraulic motors or pumps
Inventor: NOREN SVEN ANDERS
IPC: F04B53/08
Filed: 1965-02-24
Abstract: 1,044,241. Turbines. STENBERG-FLYGT A.B. Feb. 24, 1965, No. 8048/65. Heading FIT. A fluid-operated motor is disposed within a fluid-tight outer casing, the outer casing forming between itself and the exterior of the motor a chamber through which the motive fluid is caused to flow. The motor may in operation be exposed to an ambient temperature differing from that of the working fluid of the motor and the object of the invention is to prevent such temperature differences from having an adverse effect on the fine clearances between the working parts of the motor. The motor indicated at 5 in Fig. 1 is driven by hydraulic fluid supplied by pump 2 through line 3, the pump being driven by an engine or electric motor 1. The hydraulic motor 5 is disposed within an outer casing 6 and the motive fluid discharges from the motor through outlet 9 into the chamber formed between the motor and the outer casing 6, the motive fluid returning from there through line 7 back to the inlet of the pump 2. The hydraulic motor in this embodiment is utilised to drive an agitator 14, the motor and agitator being suspended below the water level 12 in a well 11. The hydraulic motor is of the kind having a rotor which rotates within a stator with narrow clearance therebetween. If the outer casing were not provided the difference in temperature between the motive fluid and the water in the well could result in the fine clearance between the rotor and the stator being reduced to a dangerous level.

Title: Improvements relating to the treatment of mineral oils by heat to obtain lower boiling oils
Filed: 1926-03-24
Abstract: 271,601. Perelis, W. J. March 24, 1926. Hydrocarbons, cracking.-In cracking petroleum oils, such as kerosene, gas oils, crude oils or residuals to obtain gasoline and residual oils suitable as fuel oils, the oil is passed in succession through the tubes of three cracking furnaces 20, 21, 22, the first of which brings it to a cracking temperature, the second allows a small reduction of temperature while maintaining it in the cracking range, and the third again increases its temperature. The treated oil is cooled, before or after releasing the pressure, and is passed into an evaporator. The oil to be treated is forced through a heat-exchanger 1, and through a pipe a into a chamber 2 in which it is sprayed through hot vapours. The oil passes from the base into a reservoir 3 and is forced by a pump 18 through a second heat-exchanger 4 and through the cracking furnaces 20, 21, 22. It is discharged through a pipe d, heat-exchanger 4, and a pressure-reducing valve 23, into a vapour-separating chamber 6, in which it may be treated by steam entering by a pipe 41. The vapours pass through the chamber 2, a dephlegmator 8, and the heat-exchanger 1 to a final condenser 26. A fuel oil is withdrawn through a cooler 42 from the evaporator 6 and kerosene is withdrawn from the base of the dephlegmator 8. The oil enters the cracking coil 20 at about 740‹ F. and leaves the coil 22 at 860-910‹ F., under a pressure of 250-450 lbs. or higher.

Filed: 1976-03-01
Abstract: 1482734 Applying adhesive tape LOVESHAW CORP 1 March 1976 [14 Jan 1976] 08091/76 Heading B8F Apparatus for applying adhesive tape to an advancing carton, and having a head which bears down on the carton during taping, comprises powered means for raising and lowering the head and controlling the loading imposed on the carton, and control means responsive to passage of the carton near the discharge end of the machine to raise the head briefly as the carton issues from beneath the head, to avoid tipping the carton by pressure on its rear end. In Fig. 1, the carton 20 is advanced from table 19 on to belts 15 so that its leading face abuts a panel 31 on the end of the fully lowered head 12. Pressure on this panel operates a pneumatic system to move guide rails 16, 116 inwardly to abut the carton and to raise the head on pillar 13 until the panel is clear of the head. The carton then advances below the head, and the head bears down on the carton by its weight, which may be aided or opposed by pneumatic forces on the head as desired. The carton is taped in known  manner as it passes beneath the head, by rollers 22, 23, 24, 122, 123, 124. At the end of its passage, the carton operates a first pneumatic valve trigger 28, resulting in withdrawal of the side rails. For a brief period, a second pneumatic valve tripper 29 is operated, but trigger 28 is not. This causes the head to be raised briefly. Then trigger 29 is released, whereby the head is fully lowered again ready for the next carton. In a modification, raising of the head by an advancing carton is subject to an operators' foot control. The operator can raise the head at any time by control 130.

The tools 10 are pivoted at 41 on levers 37 pivoted at 44 on slides which may be moved horizontally in the direction of the rails 12. The pivots 44 are connected by links 40 to opposite ends of a rocker 35 fixed to a shaft 38 which may be turned by a lever 50 connected at 51 to a screwed rod working in a nut rotatable by a gear wheel 53. The upper ends of the levers 37 are pivoted to the rods of pistons 47 which are normally held stationary by compressed air in the cylinders 48 supplied from a container 49. When the resistance of the ballast stops the tampers 10, the levers 37 rock about their pivots 44 and the pistons reciprocate in their cylinders. In another form, the upper row of the tampers are turned inwards, so that the tamping action takes place during a pulling movement of the rods 43. In the form shown in Fig. 4 the tampers are carried by levers 54 pivoted at their upper ends to the actuators 62 and connected by links 55 to rockers 56 carried by horizontally adjustable nuts 57. The upper ends of the rockers are connected to pistons 60 in cylinders 61 provided with spring-pressed inlet and outlet valves for compressed air.
