Abstract: 1,131,121. Automatic speed control. MARWIN MACHINE TOOLS Ltd. Jan.24, 1967 [Jan.25, 1966], No.3209/66. Heading G3R. A variable stroke hydraulic motor is driven through a servovalve which meters the output of a source of fluid at constant pressure, and a tachometer registers the speed of the motor as an electric signal which is fed back to control the servovalve. The source of fluid is a pressure compensated pump, or a fixed output pump with a large accumulator fed through an unload relief valve. The motor may be of the swash-plate type. As shown, a constant pressure pump 10 supplies a variable stroke hydraulic motor 14 through valve 12, the motor driving a tachometer generator 16 which provides a feedback signal to control the valve to compensate for spindle loading. The feedback circuit comprises an operational amplifier 22 and a booster amplifier 24. The stroke of the motor 14 is controlled by unit 26 in accordance with signals in binary code which are decoded by a unit 30 to provide preset stroke positions, and a reference voltage for the amplifier 22 through generator 32. Speed is restricted by an indicator 34 and logic unit 36. In another embodiment, the amplifier 24 is fed by two pressure transducers indicating the difference in pressure across the servovalve and the motor respectively.

Title: Laser range finders
IPC: G01S7/499
Filed: 1974-01-24
Abstract: 1477201 Radar FERRANTI Ltd 16 Jan 1975 [24 Jan 1974] 3416/74 Heading H4D In a pulsed laser radar, the sensitivity of the echo detection and the degree of protection from echoes from clouds &c. in front of the target, are both improved by making the transmitted pulse radiation distinctively polarized and passing the echo pulses to the detector through polarization selective optics. An IR Q-switched laser 10 passes its beam through a Nicol prism 12 to a  wave plate 13 which changes the polarization to circular and telescopic optics 14, 15 directs the circularly polarized beam to the target X. If no cloud or mist intervenes, 20-40% of the reflected light has its polarization orthogonally changed, leaving 80-60% unchanged. The unchanged echo-portion is converted back to linear polarized radiation perpendicular to the transmitted plane by the  wave plate, to be deflected by prism 12 to detector 17. If it is known that cloud or mist is present, giving spurious echoes having unchanged polarization, the  wave plate 13 is removed so that the 20-40% changed portion of the "true" target echo is detected. The IR laser beam is reflected to the target X by beam splitter 31, an observer 32 viewing the target through the beam splitter 31, which reflects IR but transmits light, and an IR safety filter 33.

Abstract: 620,976. Epicyclic reversing-gearing. DUNLOP RUBBER CO., Ltd., and DAVIES, T. E. Feb. 6, 1947, No. 3501. [Class 80 (ii)] In reversing gearing comprising a sunwheel 5 integral with a driving shaft 1 and frictionally engaging planet wheels 6, the driven annulus 10 is axially located by planet carrier flanges 8, 9 rotatably mounted on shaft 1. Sleeve 13 integral with flange 9 slidably carries an annular member 14 to which is attached a ring 16 forming the female part of a cone clutch, the male portion 19 of which is splined to shaft 1 and prevented from axial movement by a flange 21. Arcuate slots 17 formed in the ring 16 are provided for engagement with two pins 18 secured in the frame 3. An operating ring 23 located between a shoulder and nut 25 on the member 14 may be actuated by a bifurcated arm 28 pivoted at 29 on the frame 3. In operation, movement of the ring 23 to the right causes engagement of the cone clutch thus establishing forward drive with the gear locked solid. Reverse drive at a reduced speed is effected by rocking lever 28 to the left thereby causing the carrier to be braked by engagement of pins 18 with slots 17. In modification, a disc brake is used for braking the carrier and for the forward drive, plungers extending through the flange 9 force the wheels 6 against the flange 8. The friction roller drive may be replaced by toothed gearing.

Abstract: 1,030,732. Conveyer systems; bumpers. SI HANDLING SYSTEMS Inc. Jan. 28, 1963 [Jan. 29, 1962], No. 3518/63. Headings B7J and B7L. A conveyer system has a truck 20 moved by a dog 120 on chain 118 engaging a pin 44 on the truck extending through a slot 14 in surface 12, the pin being held in the operative position by a pivoted hook 71 against the upward bias of a spring 74, Fig. 2. With the hook released the pin 44 can be raised out of slot 14 by moving handle 42 into notches 40 on a member 36 on the truck front framework. A rod 82, Fig. 1, passes through a hole in hook 71 and is loosely mounted in bearings in pivoted members 54 each of which has holes 58 for a trip rod 64, 66. The pin 44 is also raised from dog 120 by a cam on lever 94, Fig. 2, when a bumper 88 is pivoted on striking an object, the movement of lever 94 acts, through spring 100, on a rod 98 to apply brake 114, 116 and to engage lever 104 with rear bumper 108, 109 to lock it in a position to abut the front bumper 88 of a following truck. The bumper 88 is returned by spring 100 to the shown position when the obstruction has been removed. To move the truck along a branch slot 16, the trip-rods 64, 64 are positioned to engage stops 122, 124 causing rotation of members 54 so that rod 82 engages and rotates hook 71 allowing pin 44 to be raised clear of driving dog 120 but not above surface 12. The pin engages the raised surface 130 of a switch 126, Fig. 4, to be guided into slot 16; a bumper 86 on a following truck engages base 22 to move the truck 20 along slot 16. If reds 64, 66 are not engaged by the abutments or only one is engaged, the hook is not rotated and pin 44 remains in engagement with dog 120; the pin engages the face 128 of the switch 126 to move the switch aside against spring 134. In Figs. 6-8 (not shown), the branch slots do not intersect the main slot but a second pin is projected into the branch slot as pin 44 is raised. Should a branch track be full then the pin 44 on the leading truck depresses a bar which through a cable causes the abutments 122, 124 to be lowered, so preventing a further truck being diverted into the branch track. An overload device, Figs. 9-11, not shown, limits the number of trucks accumulating in a branch slot.

Title: Improvements in and relating to the production of film
Inventor: BUTEUX RICHARD HAROLD BARCLAY
IPC: B29C48/10
Filed: 1954-02-08
Abstract: Tubular film of a synthetic organic thermoplastic material is extruded through the peripheral orifice of an annular extrusion channel formed between the plane horizontal surface of an annular die and an opposed parallel die plate, which plate has no projections beyond the plane of its extrusion surface.  The die plate is preferably detachably mounted on a core positioned within the annular die.  As shown, the peripheral orifice 7 is defined by the horizontal end surface 2 of the annular die 1, and the horizontal surface 5 of die plate 4 which is secured to the core 3 with the interposition of a resilient ring 12.  Material to be extruded is fed through the connection 13 into the annular space between the die 1 and core 3. The construction facilitates maintenance of a specified gap round the whole of the peripheral orifice, particularly after re-grinding or re-polishing the extrusion surfaces, since the surfaces concerned are plane.  Any slight variations in the gap may be compensated by providing a slightly flexible lip 21 round the die 1, whose position may be varied by adjusting a series of bolts 22 extending round the periphery.  Inflating air may be introduced through the axial bore 14.  The tubular film is preferably cooled by flowing a cooling liquid over its exterior as it passes downwardly through a suitable passageway.  Examples describe the production of tubular film from polyethylene terephthalate and polythene.  Specification 741,963 is referred to.

Title: Improvements in and relating to the removal of an aldose from food products
IPC: A23L7/104
Filed: 1963-01-29
Abstract: The storage stability of aldose-containing liquid food, e.g whole egg, eggwhite, egg yolk and milk, is improved by enzyme conversion of the aldose to the corresponding sugar acid, e.g. to glutonic acid, in the case of glucose, the conversion being effected by mixing the food with an enzyme having aldose-oxidase activity, adding acid to adjust the pH to below 8, preferably to between 5.0 and 7.5 saturating the mixture with free oxygen, maintaining it between 30 DEG  and 65 DEG F., and foaming it, e.g. either by passing oxygen or air through it, or by reducing an initial superatmospheric pressure to release dissolved gas, or by incorporating into it hydrogen peroxide, or a precursor therefor, and a decomposition catalyst for the peroxide, e.g. catalase.  The foaming floats up particles of fat, bacteria and foreign matter and facilitates their removal.  The liquid food may be pasteurized before treatment and dried, e.g. spray dried or frozen afterwards. The final pH of a dry powder can be adjusted by buffering or by adding volatile alkali such as ammonia to the liquid before the drying.  Specification 740,379 and U.S.A.
