Filed: 1973-08-08
Abstract: 1390718 Valves KARL M REICH MASCHINENFABRIK GmbH 8 Aug 1973 [17 Aug 1972] 37645/73 Heading F2V A differential valve member 7 controlled by an auxiliary valve 34 is locked in the closed position by a bolt 24 until pressure fluid is supplied to a passage 5 in the housing which may contain a pneumatic hammer for driving nails, staples or other fasteners into a workpiece. Connection of a compressed air supply to the passage 5 increases the pressure in spaces 10 and 26 to lift the valve 7 slightly from the position shown and to withdraw the bolt 24 against a spring 22. A restricted bore 28 ensures that the valve is lifted before the bolt is withdrawn. When the auxiliary valve is operated, the space 10 is connected to atmosphere to allow the valve to be pushed down into the open position by compressed air acting on its upper face 13. Compressed air is now able to flow through ports 15 to actuate the piston 3 of the hammer. The bolt 24 remains in the withdrawn position until the air supply is disconnected from the housing.

Title: Improvements in inertia safety belt mechanisms
Inventor: BLAKE MINDEN VAUGHAN
IPC: B60R22/34
Filed: 1969-07-28
Abstract: 1,242,190. Seat belt inertia mechanism. M. V. BLAKE. 16 July, 1970 [28 July, 1969], No. 37740/69. Heading A3V. A seat belt inertia mechanism comprises a guideway 3, a slider 6, a member 9 linked to the slider 6 by pivoted teeth 12 and a spring 15 which tends to draw the slider 6 and the member 9 together, and a belt 1 joined to the slider 6 by a loop 8 around a clasp 7. When the belt 1 is jerked upwards with acceleration greater than a predetermined value such as would occur if the vehicle was involved in a collision, the inertia of the member 9 causes it to lag behind the slider, causing the teeth 12 to pivot and force the member 9 closer to the rough inner wall 16 of the slider 3. A rubber pad 17 fixed to the member 9 is consequently compressed against the wall 16 and the member 9 is prevented by friction from moving upwards. Neither the belt 1 nor the slider 6 can therefore move upwards, as they are locked in position by the teeth 12. In normal use the belt 1 is held against the body of the user by the gravitational force on the slider 6 and the member 9. The mechanism may also be adapted to respond to deceleration or changes of orientation of the vehicle itself, for example by a tumbler balanced in a recess in the slider, which prevents the slider and the member separating until the tumbler is toppled by a predetermined deceleration or angle of attitude of the vehicle.

A skip or hopper 10, Fig. 1, has its bottom discharge opening closed by a circular plate 56, Fig. 4, which is attached to a bar 66 by a screw 62, the bar 66 being hinged to the skip by a pin 70 and held in a closed position by a latch member 78. The skip is placed on a stand 12, Fig. 1, for emptying, legs 30 being of such a length that a rubber gasket 44, Fig. 3, on a hopper 42 is compressed by the lip of the discharge opening and forms an airtight seal. Rotation of a shaft 84, Fig. 4, swings a bar 82 away from the position in which it supports the bar 66 thus allowing the weight of the contents of the skip to open the plate 56. The shaft 84 is rotated by means of a hexagonal nut 88, Fig. 3, access to which is gained through a hole in the side of the hopper 42 covered by a flap 94. The hopper 42 may discharge on to a floor or any type of conveyer instead of a screw conveyer as shown. The latch member 78 moves to an over-centre position in which it is held by the weight of the contents of the skip. In addition a safety pin 102, 104, Fig. 4, is provided to prevent accidental discharge of the skip during transit. The latch 78 may be operated pneumatically.

Abstract: 1,146,434. Frequency discriminators. ELLIOTT BROS. (LONDON) Ltd. 28 Nov., 1966 [4 Sept., 1965], No. 37901/65. Heading H3A. A frequency/voltage converter for a pulse input signal comprises a capacitor C1 charged from a source V<SP>1</SP> via a diode D1 and a transistor T2, and discharged through a path R4, C2, 11 to produce an output voltage VO dependent on the mean discharge current, the time constant of the discharge path being such as to ensure completed discharge of the capacitor C1 between consecutive input pulses. The diode D1 and transistor T2 are both silicon and are so arranged that the voltage drop across the diode opposes that across the base-emitter path of the transistor. The input at VI is a positive voltage having zero-going pulses which cut off transistor T1 for the duration of each pulse to forward bias diode D1 and render transistor T2 conducting. Positive pulses of amplitude V<SP>1</SP> are thus applied through the base-emitter path of transistor T2 to charge capacitor C1.

A punched tape which requires correction is read by a first reader, a second tape bearing corrections to be made is read by a second reader, one or other reader being selected to control a tape punch so as to produce a corrected tape. In operation, the first reader reads the original tape continuously, a new punched tape is produced, and the information on the tape is printed by a line printer. When the operator sees that the first (printed) line to be corrected is approaching, he operates the selector so that the machine reads and reproduces one (printed) line at a time and then stops, the operator re-starting the machine to read and reproduce the next line until the first line to be corrected is reached. The operator then selects the second reader so that the corrected line or lines is or are fed to the punch and printer either continuously or line by line as desired. At the end of the corrected passage, the original tape is advanced to the corresponding position without operating the printer or punch, then the following information on this tape is again reproduced until the next line to be corrected is reached.

Title: Method of and apparatus for producing biconical spools of yarns on winding machines
IPC: B65H54/06
Filed: 1976-09-22
Abstract: The use of control devices for the positive reduction of the stroke of the thread guide is limited by speed on account of the masses to be moved. In order, even at higher thread speeds, to obtain thread packages having a conicity on the side faces, the traversing speed of the thread guide for the thread to be laid on the bobbin is increased with an increasing diameter of the thread bobbin. Between the thread guide (9) and the lay-on point on the thread package, the thread (5) moves over a free zone which is under a drag effect, the thread (5) forming, on the drag path (2), a drag angle relative to the normal (23) to the axis (24) of the roller (4). The size of the drag angle is obtained from the circumferential speed of the friction roller (4) and the stroke speed of the thread guide (9) executing a constant stroke (26). The faster the traversing of the yarn guide takes place, the larger the drag angle becomes. With an increasing diameter of the thread bobbin, a reduction of the stroke length of the thread being deposited on the thread bobbin is obtained. A conicity on the end faces of the forming thread package is thereby achieved. <IMAGE>
