Abstract: 804,430. Pile &c. pulling devices. DORNFELD R., and DORNFELD, E. Aug. 24, 1956 [Aug. 30, 1955], No. 26008/56. Class 68(2) A pile and plank pulling device of the Diesel ram type wherein the forcs of compression of a descending ram are converted into traction forces acting in an upward pulling direction, and which may readily be converted into a pile driving device, comprises four rods 1 which guide the ram 12 and are suspended, by springs 7, from a tackle head 8. When for traction a cylinder 2 is suspended from a bridge 11 screwed to the guide rods 1, and the tackle head 8 is kept under tension by means of a winch, not shown. A traction rod 21, passing in liquid tight manner through the base of the cylinder 2, has, within the latter a stop 4 and an enlarged cylindrical head 4 slidably engaged within an inner bore 3' of a piston 3 vertically slidable within the cylinder 2. The space 6 in the cylinder 2 between the lower end of the double piston constitutd by the two parts, 3, 4<SP>1</SP> is filled with a liquid. Each time the ram 12 descends after the diesel cycle has commenced, the high hydraulic pressure, produced by the impact on the piston 3, acts upward upon the head 4<SP>1</SP> of the pull rod 21, and provides a withdrawal force for the pile, or plank. Starting and stopping the diesel ram is effected by means of a winch 9 and a pawl runner 10 which is slidable in a fixed channel iron 22 fixed to one of the guide rods 1 and is suspended from a winch rope 14.

Title: Apparatus for blocking a laser beam
IPC: H01S3/00
Filed: 1975-06-18
Abstract: 1488454 Lasers COMPAGNIE GENERALE D'ELECTRICITE 18 June 1975 [21 June 1974 30 Sept 1974] 26039/75 Heading H1C [Also in Division G2] To prevent a pulsed laser beam directed at a target from being reflected back along its original path, the beam is passed through a germanium or silicon semi-conductor plate in which beam suppressing charge carriers are generated after the passage of the pulse output beam and before the return of the reflected beam. The charge carriers may be generated by an incident beam directed at the semi-conductor plate by a second laser, Fig. 1 (not shown) and Fig. 5, or by using a proportion of the incident beam which is focused adjacent the plate after passing through a reflecting optical path imposing the necessary optical delay, Figs. 2 and 3 (not shown), Fig. 4 and Fig. 6. In Fig. 5 a beam F 1  from a CO 2  laser is incident on a target 2, and the reflected beam F<SP>1</SP> 1  is suppressed by charge carriers on a surface of a semi-conductor plate 3 generated by a beam F 2  from a neodymium-glass laser 4. Additional suppression may be provided by the combination of a polarizer 10, an analyser 11 and a magnetizing coil 12, the polarizer and analyser normally allowing the incident and reflected beams to pass, but suppressing the reflected beam when the coil is energized due to the semiconductor plate producing Faraday rotation. Fig. 4 shows an arrangement in which the semiconductor plate 3 is oriented at approximately the Brewster angle to the incident beam, the beam being in part reflected by the plate and then by a spherical mirror so as to focus at # adjacent the plate. Energy F 4  from the focused beam F 3  produces charge carriers in the plate to suppress the reflected beam F<SP>1</SP> 1 . This energy may be concentrated in the plate by a further reflecting path provided by a plane or convex mirror 7 and the mirror 6. Instead of using the semi-conductor plate as a beam splitter, a separate partial reflector 5, Fig. 6, may be used. This arrangement also includes the further reflection-suppressing arrangement of Fig. 5 comprising polarizer 10, analyser 11 and magnetizing coil 12.

Abstract: 892,295. Openers; forming fibre webs. T.M.M. (RESEARCH) Ltd. July 27, 1960 [July 29, 1959] No. 26075/59. Class 120(1) Fibres are opened as for cotton blow-room processes or for non-woven fabrics and are formed into webs by the action of a rotary heater that disintegrates fibre groups and generates an airstream to deliver fibres to a foraminated conveyer, the heater creating pressure on one side of the conveyer and suction on the other. In one form of apparatus, a heater 10 with a spiked, bladed or sawtoothed periphery disintegrates a fringe of fibres fed by a roller 14 and feed plate 15 and causes the fibres to be carried in an airstream A directed through a perforated conveyer 19 on which the fibres are deposited. Control over the airstream is afforded by a shutter 121 and its direction is in part determined by a baffle 16. If desired, a rotary stripping brush, roller, fan or the like 24 may be mounted adjustably in operating relationship to the heater 10. A modified arrangement has the web of fibres deposited on a perforated drum provided with an internal baffle to direct the airstream through it.

Title: Improvements in or relating to laundry apparatus
IPC: D06F37/22
Filed: 1939-09-20
Abstract: 534,902. Washing machines; centrifugal dryers. WESTINGHOUSE ELECTRIC INTERNATIONAL CO., Sept. 20, 1939, No. 26232. Convention date, Sept. 30, 1938. [Class 138 (ii)] [Also in Group II] A combined washing and centrifugal drying machine comprising a basket mounted on an inclined driven spindle within a resiliently supported tub carrying the driving motor and gearing as a self contained structure is mounted so that the inclination of the spindle to the vertical is greater during washing, when the tub contains water, than during the operation of the machine for extracting water. The basket 13 is secured to a spindle 33 mounted in a bearing 34 on a tub 17 and driven by a belt 38 and change speed gear 36 from a motor 35 carried from the tub which is housed in a structure 10 formed of a skeleton framework 11 and seating 12. The tub is resiliently supported at each side by sets of springs 56, and a rod 63 connected by a ball joint 64 to the tub extends through a channel 16 on the framework and carries a rod 62 of friction material and a washer 66 with a resilient upturned flange When the tub is charged with washing liquid its centre of gravity is forward of the joint 64 and it tilts so that the pad 62 rests in a cup 61 to give partial support and oppose vibration of large amplitude. During washing, the clothes are carried upwards and towards the base of the basket by lifters 18 formed on the basket, the clothes then falling on the domed base 25 which displaces them towards the top of the basket. After washing is completed the liquid is drawn off through outlet 50, valve 51, impellor 48 and flexible waste pipe 53, causing an automatic lifting and tilting of the tub and basket under the action of the springs 56 to the position shown in which the pad 62 is clear of the cup. The basket is now driven at an increased speed passing rapidly up to the required exhausting speed, and an inertia mass 67 secured to the tub operates to restrain excessive vibration, which is further reduced initially owing to the clothes being near the base of the basket. The sequence of operation may be effected manually or automatically. As shown a manually controlled knob 73 serves to rotate a drum with segmental contacts which successively make contacts to complete circuits (1) to a solenoid 47 to open a valve 46 for the supply of liquid through a flexible connection 45 to the tub : (2) to a circuit to a solenoid 42 for setting the change speed gear 36 to slow speed for washing (3) to a solenoid 52 for opening the valve for emptying the tub: and (4) to the solenoid 42 for setting the change speed to high speed for liquid extracting. The solenoids are returned by springs when demagnitized.

Title: Improvements in and relating to caging signal devices for gyroscopes
IPC: G01C19/44
Filed: 1946-09-03
Abstract: 635,126. Gyroscopic apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 3, 1946, No. 26477. Convention date, Sept. 5, 1945. [Class 97 (iii)] Caging signal means are provided which indicate the position of the caging mechanism and whether the mechanism is locked or unlocked in the caged or uncaged position. The caging knob 10, Fig. 3, is mounted on a rotatable shaft 11 having a slotted end portion 12 in which the actuating shaft 13 of the caging mechanism is fitted. As shown, the shaft is in the caged position and is locked therein by an index pin 16 projecting from the front face of the instrument engaging a hole 17 in the knob. To uncage the gyro the knob is pulled out, unlocking it from the pin 16, and rotated counterclockwise through about 300 degrees and then pushed in, so that locking in the uncaged position is affected by a second hole 18 engaging the pin 16. , The indicating means comprise a plate 22 secured to but spaced from the dial plate 19 by means of screws passing through holes 24, 25 and screwing into the instrument face plate, the front of the indicator plate 22 being provided with suitable indicia such as the word " caged." The indicator plate 22 has lugs 26 serving as guides for the support 6 which carries the conventional model aircraft horizon index and which may be adjusted by knob 7 and pin 9. The dial plate 19 has a tongue 21 with a window 27 through which the indicator plate 22 may be viewed. A shutter 28 mounted for movement in the space between the tongue 21 and the indicator plate 22 is pivoted at its lower end which carries a cam follower member 32, Fig. 4, mounted on a right-angled projection 33 of the shutter lever. The cam follower member 32 co-operates with a three-level cam 31 mounted on the caging knob shaft 11. With the caging knob in the caging and locked position (as shown) a projection 34 of the cam follower 32 is positioned by the first level 35 of the cam so that the shutter is in its lowest position and completely unmasks the indicator plate 22. On withdrawal of the knob, preparatory to its rotation, the cam follower projection 34 rides on to the cylindrical second level 36 and remains there during subsequent rotation. In this position the shutter 28 partially masks the indicator 22. When the knob 10 is pushed in to lock the mechanism at the uncaged position the cam follower projection 34 engages the third level 37 of the cam 31 and the shutter is thereby moved so as to mask completely the indicator 22. The shutter is biassed by spring 30. The cam 31 may be adjusted by disengaging the tongue 39 of the caging lever 13 from the slot 40 and screwing the cam axially on the shaft 11 and the cam follower projection 34 may be adjusted relative to the cam surfaces by releasing screw 42 which passes into a slot 43 of the projection 33.

Filed: 1933-06-29
Abstract: 404,248. Fuel - injection pumps. ALDER, S., 3, Westcliffe Road South, Roker, Sunderland. June 29, 1933, No. 26490. Divided on 402,886. [Class 102 (i).] In a fuel injection pump of the constant-stroke plunger type the point of time when injection ceases is maintained constant and the amount of fuel injected controlled by varying the time of commencement of injection. The motion of the plunger is obtained from a cam through a follower 15 and a wedge 21 which pivots about an arm 30. The position of the wedge determines the position of the plunger relative to the cam and therefore the time of commencement of injection, that takes place when the inner edge of plunger covers the suction ports 9. The end of injection occurs when the release ports 6 in plunger are uncovered by the edge of the guide 4. As the movement of the arm 30 raises or lowers the plunger the lever 23 moves the guide an equal amount so that for any position of the wedge the end of injection remains constant. In a modified form the plunger is actuated by means of a yoked end engaging an eccentrically driven lever, the position of which is adjusted by means of a hand nut and link bolt to vary the commencement of injection. The link bolt supports both the lever and also a second lever which adjusts the guide.
