Title: A mechanism for releasing a man from an ejector seat
Inventor: REFFELL BRIAN RICHARD ARNOLD
IPC: G05G5/20
Filed: 1962-12-28
Abstract: 984,479. Stud and socket fastenings. WALTER KIDDE CO. Ltd. Dec. 5, 1963 [Dec. 28, 1962], No. 48912/62. Heading E2B. In a device comprising a body 1 adapted to be attached to an aircraft ejector seat by a member movable in response to a barometric device for disconnection from the seat, a first anchorage member 3 is slidably mounted for limited movement in the bodyl and provides an anchorage point 4 for a dragnet line at one end of the body, and a second anchorage member 10 projecting from the opposite end of the body for attachment to a parachute static line and mounted coaxially with the first anchorage member, the second anchorage member having a cylindrical portion 12 slidably mounted in a bore in the body and provided with one or more apertures to receive a corresponding number of axially slidable locking members 14 which are normally held in an inwardly projecting position by engagement with the wall of the bore so as to engage within an annular recess 17 formed in a co-operating portion of the first anchorage member, the bore being of such length, that an outward pull on the second anchorage member 10 may draw out the second anchoraged member and the first anchoraged member to a point beyond the end of the bore to permit release of the locking members 14 from the annular recess 17 in the first anchorage member 3. As shown, the body 1 is provided with an aperture to receive a bolt not shown, by which the body is attached to the seat and which is operated by a barometric device to release the body from the seal when the latter has been ejected at ground level or below 10,000 feet with a 3 second delay, the arrangement being such that so long as the body 1 is attached to the seat the drogue line pull on the member 3 holds abutments 6, 7 between the member 3 and an insert 5, against one another, and when the seat is released maintains the abutment so that the drogue line pull is transmitted through the second anchorage member 10 to the static line of the parachute which is then deployed. If the barometric device fails to release the seat, the static line of the parachute may be tensioned by the occupant of the seat thus to separate the member 10 from the remainder of the body and thus from the seat.

Abstract: 1,207,134. Printed circuits; thin film capacitors. WESTERN ELECTRIC CO. Inc. 31 Oct., 1967 [2 Nov., 1966], No. 49354/67. Headings H1M and H1R. In order to form two spaced conductive layers which are free from short circuits the two conductive layers are separated by a thin film of material which is subsequently removed by dissolving to expose any pin hole shorts which are then eliminated. A thin film capacitor, Fig. 1, is formed by depositing a gold layer 2 on an insulating substrate 1, then a copper film 3 and finally a second gold layer 4, the two gold conductive layers forming a cross-over. The copper filler 3 is removed by etching so as to leave an empty space between the layers 2 and 4 and expose any pin-hole shorts such as 5. The shorts may be removed by oxidization, immersion in a transducer-agitated liquid, ultrasonic cleaning or centrifuging. A dielectric may be produced in the space between the layers by forming oxide layers on the internal surfaces of the conductor layers or anodization. In a second embodiment, Fig. 3, a thin film cross-over is produced between contacts 11, 12 over conductor 13. The contacts 11, 12, and conductor 13 are deposited on a silicon substrate 10 coated with SiO 2  or SiN 2  and comprise titanium 14, platinum 15, and gold layers 16. A layer of zirconium 17 is deposited where indicated and a copper spacer layer 18 positioned on the top thereof. Contacts 11 and 12 are then joined by an upper gold layer 19. The copper layer 18 is again etched away to expose any shorts which are eliminated and the zirconium 17 is oxidized.

Abstract: 1422322 Binary arithmetic units F WALDSCHMIDT 2 Jan 1973 [25 Oct 1971 (2)] 49409/71 and 49410/71 Heading G4A A parallel adder for decimal numbers whose digits are represented by operands in 5211 or 4221 code includes groups of four full binary adder stages. For any one group of stages A4, A3, A2, A1 (A4 most significant) the weighting of the bits applied to stages A3, A2, A1 respectively is in the ratio 2 : 1 : 1. To correct the error that would otherwise occur when there is a carry bit into one or the other, but not both, of stages A4 and A1 the output of stage A1 is forced to the value where Z4 is the carry into stage A4, Z1 is the carry into stage A1 and X1, Y1 are the operand bits applied to stage A1. The two operands must be respectively in the A and B form of the relevant code. In the case of 5211 code the operands applied to any one group represent like-ordered decimal digits of the numbers to be added. In the case of 4221 code each operand applied to a group represents the least significant bit of the 4-bit word representing one decimal digit and the three most significant bits of the word representing the decimal digit of next lower order. Subtraction may be performed by adding the 9's-complement. The circuitry (not described) may be integrated.

Abstract: 1371100 Counting sheets; zeroizirig DE LA RUE INSTRUMENTS Ltd 21 Jan 1972 [23 Oct 1970] 50376/70 Heading G4D A banknote counting machine of the kind having a vacuum separator head such as is described in Specification 1,243,785 has a spring- urged clamp 3, 4 to hold the stack of banknotes, the clamp being coupled to an actuating device 26 which can open the clamp automatically if a predetermined count is being registered by the counter at the end of a counting operation. The clamp comprises a first arm 3 coupled to a shaft 22 and a second arm 4 freely pivoting on the shaft; a light spring 52 urges the assembly towards the vacuum heads (Fig. 1, not shown) while a stronger spring 33 urges the two arms 3, 4 together. During counting a bellows 35 is coupled to the vacuum line and acts to assist spring 33 to prevent the clamp being opened. The actuating device 26 comprises another bellows 26 which is connected to the vacuum line when the clamp is to be opened automatically. The two bellows 26, 35 and the vacuum heads are connected to vacuum by solenoid valves energized through a series of relays according to the position of a mode selecting switch. Three modes of operation can be selected: in mode I, with the counter reset to zero a bundle of notes can be inserted between the arms of the open clamp; a start button is pressed and counting begins. While counting continues the bellows 35 holds the clamp closed; when all the notes have been counted and after a short time delay, if the units wheel of the counter shows zero bellows 35 is released and 26 opens the clamp. If, however, the units wheel does not show zero, signifying an incorrect count, the clamp remains firmly closed until the reset button (57) is operated to restore the counter to zero. In mode II operation is similar but the clamp is not opened at the end of the count and mnst be opened manually by handle 24. In mode III the automatic system is inoperative. Counting is by pressure pulses produced at the counter head as the notes are passed over; these are sensed by a pressure switch (58) which applies electric pulses at X to a pulse shaper. The register comprises a plurality of electromagnetically operated wheels with electrical carry contacts. Resetting to zero is by switch S7 which energizes a pulse generator whose pulses are fed to all stages of the register until they reach zero (Fig. 5).

Abstract: 1456043 Forming yarn reserves F M N SCHUSTER & CO 31 Oct 1973 [9 Nov 1972 18 June 1973 11 Oct 1973] 50560/73 Heading D1J Fig. 1a shows the start of a winding operation in which a thread 1 has its leading end positioned as at 1a by an operator to engage it in entrainment means 15 in a spool 5 driven by a friction roller 10. The direction of rotation of the spool 5 is such that slack would tend to appear in the thread 1 until the spool 5 has rotated to a setting in which the yarn enters the pinch between the roller 10 and the spool 5 and wind up commences. Such slack is prevented by a blower 16 blowing the slack for a short period in the form of a loop 1b into an open chamber. As wind up commences the loop 1b is drawn back until the thread adopts the straight line configuration shown in Fig. 1b. During this time a reserve winding is formed on the spool 5. As soon as the thread 1 becomes taut, the thread can slide over a deflector pin 24 and is automatically passed into a thread guide 8 of a traverse device 9. Thereafter the build-up of the thread package begins in known manner. During the formation of the thread package the blower 16 is out of action. The positioning of the deflector pin 24 and the intensity of the blower 16 determines the length of the reserve winding. Fig. 7 shows a modified embodiment in which the deflector pin 24 is replaced by a rotary worm 30 that may be freely rotatable or be pneumatically driven. The thread end is passed through a slot 39 to a spool 5 below the slot 39 and is secured in the spool groove 15 as before. Then as the spool commences to rotate a slack length is formed for a short period. This slack length is taken up by an air stream or jet 43 that blows a loop of thread into a chamber 21 and so maintains the thread in a state of tension. Continued rotation of the spool straightens out the thread and causes it to engage the smaller inner end of worm 30. The rotating worm 30 causes the thread to be laid as a thread reserve on the spool 5 and thereafter the thread leaves the worm 30 to be grasped by the oscillating thread guide 8. The speed of rotation of the worm 30 can be regulated by a throttle 34. Figs. 12 to 15 (not shown) show a device similar to that of Fig. 7 except that there is a retractable blocking device (48) that can delay the instant at which the thread is permitted to engage the worm 30, the purpose of the blocking device (48) being to ensure that there shall be a waste winding (57) on the spool 5 before the reserve winding (58) is formed. The waste winding (57) absorbs the thread that has not been wound up under correct tension as the spool 5 is building up to speed. The retractable blocking device may be a pin that is normally retracted to an inoperative position by spring means, an adjustable bleed valve determining the time taken for the pin to be moved to its inoperative position by the spring.
