Title: Improvements relating to harnesses
Inventor: SPOUGE ERIC HERBERT
IPC: B60R22/26
Filed: 1961-11-15
Abstract: 1,049,774. Buckles; friction grip fastenings. TELEFLEX PRODUCTS Ltd. Nov. 8, 1962 [Nov. 15, 1961; June 14, 1962], Nos. 40902/61 and 22907/62. Heading E2A. [Also in Division A3] A harness for protecting passengers or securing articles in vehicles includes snubbing means through which a strap or straps can freely pass whilst they remain unfastened about the person or article but which after fastening of the straps prevent their elongation under tension. In a first embodiment in which the snubbing means is incorporated in the buckle, straps 10, 12 are threaded through buckle members 40, 70 respectively and doubled back on themselves being fixed to an anchorage at one end and to a spring-loaded take-up device adjacent the other end. The first buckle part 40 consists of a base 42 having upstanding wings 44 between which is mounted a bar 46 and a pivot pin 50 and having abutments 52 and guides 54. The harness strap 10 is looped round a fixed rod 62 of a snubbing clip 56 which is pivoted on the pin 50 and comprises also side arms 58 connected by a hand plate 60 and a movable snubbing bar 64, the reduced ends of which are slidably mounted in short slots (not shown) provided in the arms 58. The side arms 58 are also provided with short pegs 68. The second part of the buckle is a second snubbing clip 70 comprising two side arms 72 joined by a hand plate 74 and a bar 76 carrying a loop of the second strap 12. In use the bar 76 is inserted through the clip 56 between the pivot pin 50 and the pegs 68 and the hand plate 60 is pushed towards the base plate 42, whereupon the clips assume the position shown in Fig. 3, locking the two parts of the buckle together and locking the strap loops against running movement. In a single strap harness the second buckle part is mounted on a fixed anchorage. In an alternative embodiment (Fig. 1, of Application No. 22907/62, cognate not shown) a conventional buckle allowing free running of the straps therethrough is used and the snubbing device is associated with the take up device. The or each strap 14 is secured at one end to a shaft 12 and at the other to a rod 18 carrying end levers 20 attached to a slotted shaft 22 through which the strap is threaded Retraction springs 16 are secured at one end to the shaft 12 and at the other to the rod 18. A fixed snubbing bar 24 lies close to the shaft 22 and a guide roller 26 keeps the straps aligned with the slot in the shaft 22. In use, before fastening the buckle members, pull on a buckle member unwinds the strap from the spindle 12. When the buckle is fastened about the person tension due to movement of the body pulls both runs of the strap rocking the levers 20 and shaft 22 so that the strap is snubbed against the bar 24. An auxiliary spring may be provided to urge the shaft 22 out of the snubbing position.
Patent GB-409377-A (GB)
Abstract: 409,377. Automatic exchange systems. AUTOMATIC ELECTRIC CO., Ltd., Strowger Works, Liverpool. Oct. 31, 1932, No. 30618. Convention date, Dec. 14, 1931. [Class 40 (iv).] A two-directional group selector gives access to ten groups of outgoing lines which may be irregular in size so that some occupy parts of two adjacent levels. The first line of each group lies in a different level and when the selector is set to a particular level in which the first line of such a twopart group occurs, it normally hunts over the part of the group in that level, but if all the lines are busy it takes an additional vertical step and hunts over the remainder of the group in the next level. In the example shown, the first group occupies the whole of level 1 and six contacts of level 2, the second group the last four contacts of level 2 and the first three of level 3, and the third group the last seven of level 3. Detailed operation. Line relay 20 closes a circuit through both windings of release relay 21 in series with the lower winding of changeover relay 22. Relay 21 operates closing a circuit through the upper winding of relay 22 which then operates and energizes relay 23. The incoming impulses are repeated to vertical magnet 27 and during the digit relays 21, 22, hold, the former due to a short-circuit around its upper winding at each " break " and the latter due to a shunt circuit through its lowresistance lower winding at each "make." At the end of the digit (1, say) relay 22 falls back and in the period before the relapse of relay 23, relay 24 tests over vertical wiper 38. If there is an idle line in the first level relay 24 does not operate and on the relapse of relay 23, the wipers are rotated in the usual manner by self-interrupting rotary magnet 28 under the control of test relay 25 connected to test wiper 32. If there is no idle line in the first level, the vertical wiper 38 finds ground over a chain circuit including bridging wipers 31 of all the selectors engaging the busy lines so that magnet 27 is operated to step the wipers to the next level. Relay 24 also operates to switch over to the second test wiper 31 and test bank 35 to which the test conductors of the remainder of the lines of the first group are connected.

Title: High frequency pulse generator
IPC: H03K3/33
Filed: 1962-10-31
Abstract: 1,022,347. Semi-conductor pulse forming circuits. SPERRY RAND CORPORATION. Oct. 31, 1962 [Nov. 14, 1961], No. 41135/62. Heading H3T. . Short pulses are produced by applying input signals to two connected diodes 104, 106, one at least of which has enhanced charge storage properties, so that the other conducts when the stored charge in the first is dissipated. As shown, when the sine wave or other repetitive signal 100 is negative, diode 104 conducts and, due to the forward voltage across the diode, a resonant circuit 110, 112 charges. During the first part of the negative half-cycle the diode remains conductive due to charge storage but when conduction ceases a very rapid rise of voltage occurs allowing a biased diode 106 to become conductive and so to apply a pulse to the load. This pulse is made squarer or otherwise shaped by the discharge of energy from the tuned circuit.

Abstract: 998, 397. Sewing machines. G. M. PFAFF A.G. Oct. 18, 1963 [Oct. 24, 1962], No. 41160/63. Heading D1G. [Also in Division F2] In a chain stitch sewing-machine comprising an eccentric adjustably mounted on a drive shaft and connected by linkage means to the feeding means for varying the feed stroke in dependence upon the adjustment of the eccentric, the operating mechanism for a thread-carrying looper comprises an input member revolubly displaceably about the fined axis of a control shaft to displace the looper in the feed direction, output member supporting the looper and rotatably mounted upon the input member upon an axis parallel to the feed direction, first and second eccentric drive means connected between the output member and said drive draft to impart substantially constant oscillatory movements to the output member, and means operably connecting said control shaft with said linkage means. An under-shaft 6, directly coupled to the main arm shaft, carries an adjustable eccentric 17 coupled by a linkage 29 to shafts 9 and 31. Eccentric 17 is adjusted by depressing a spring-biased pin 25 to engage a notch 22 in a ring 21, and then turning the main arm shaft. Shaft 9 is coupled both to the feed dog and also to an arm shaft effecting feed oscillation of the needle. Shaft 31 carries a crank 30 formed with a pin 32 parallel to shaft 31. A member 33, journalled on pin 32, has an arm 34 coupled to the pitman 35 of an eccentric 18 on shaft 6. Member 33 also carries a pin 36 which is disposed at right angles to shaft 31 and journals a bell crank lever, one arm 37 of the latter carrying a looper 40, and the other arm 42 being connected by a universal link 44 to the pitman 43 of an eccentric 28 on a shaft 27 driven by gearing 16, 26 from shaft 6. The thread eye 41 of looper 40 thereby moves in a path 39 having a constant loop-taking component imparted thereto by eccentric 28 in a direction transverse to the line of feed, and a needle-avoiding component which is parallel to the live of feed and which has a constant component imparted thereto by eccentric 18, and a variable component imparted thereto by eccentric 17 and thereby proportional to the rate of work feed. It is stated that the arrangement can be used either in two-thread chain stitch machines, or in twoneedle machines producing covering stitches of the federal 402 type. Alternatively, arm 37 may carry a plurality of loopers each co-operating with a separate needle. Reference has been directed by the Comptroller to Specification 869,637.

Title: Direct reel-to-reel tape transport
IPC: G05D13/62
Filed: 1976-10-06
Abstract: 1509859 Automatic control INTERNATIONAL BUSINESS MACHINES CORP 6 Oct 1976 [14 Nov 1975] 41546/76 Heading G3R In bufferless reel to reel tape apparatus, the current to each drive motor for each reel is controlled in accordance with the reel inertia as determined from the calculated radius of tape on that reel. In the embodiment, the speeds of each reel and the linear speed of the tape are measured by digital tachometers, the radius of tape on each reel is calculated at 38, 40 from these speeds and a table in store 88 read so as to determine the reel inertia appropriate to that radius. This inertia signal is combined in multiplier 92 with a tape speed or longitudinal position error derived from the tape linear speed, and the result summed with terms related to tape friction and tension. The summer output is passed through a D to A converter and a differentiating filter to form the reference for a closed loop current control for the respective motor. This system is digital (e.g. with a microprocessor) with multi-plexing to allow control of both motors by the same apparatus. The calculation of radius, at 38, 40, uses a counter that samples the count of pulses from the reel and tape tachometers once every revolution of the reel. To determine the tape speed error, a counter counts for the period between successive pulses from the tape tachometer and compares this with the period of reference pulses from an oscillator. The frictional term to adder 96 is taken to be constant or is derived by integration of the speed error using a counter that counts in a direction depending upon the tape speed. In an alternative, an analogue system may be used with analogue tachometer signals. Details of devices 38, 40, friction compensator 94 and error calculator 42 are given in Figs. 3 to 5 (not shown), and control algorithms are derived in the description.

Abstract: 1,196,157. Transistor timing circuits. BERKEY PHOTO Inc. 12 Sept., 1967 [21 Sept, 1966], No. 41581/67. Heading H3T. In a timing circuit, a capacitor 11 is initially charged with one polarity until a timed interval is initiated by operation of first switching means 17, 18 which allow capacitor 11 to discharge via a variable resistance 30, 36 and to tend to recharge with opposite polarity, semi-conductor switching devices 45, 58 being provided to detect the change in polarity and to terminate the timed interval. As shown, capacitor 11 is initially charged with its lower plate positive until the starting switch 23 is closed, when relay 15 is energized, contacts 17 and 18 of which allow capacitor 11 to discharge via variable resistors 30, 36 (calibrated in minutes and seconds) towards a potential of opposite polarity. When the potential across capacitor 11 reverses, transistor 45 and thyristor 58 become conductive, energizing relay 54 which releases relay 15 and terminates the timed interval. Contacts 16 of relay 15 provide an alternating voltage at the output terminal 64 during the timed interval. Coarse adjustment of the timed interval is achieved by switch 43 which connects further capacitors 12, 13 in parallel. Alternatively (Fig. 2, not shown) this function may be achieved by switching in appropriate ones of a plurality of series-connected potentiometers 9.

Abstract: 1,035,726. Electromagnets. ELDIMA A.G. Oct. 22, 1964 [Nov. 15, 1963], No. 43098/64. Heading H1P. [Also in Division F2] The armature of a plunger-type electromagnet is guided by ball-bearings 45 to eliminate friction. The armature 39 has a tapered magnetic polepiece 28 and an axial bore 38 within which the ball-bearings roll. Within the ball-bearings is a locating sleeve 32 providing the inner race of the balls. The armature is attached to a valve spindle 7, sealed by bellows 9, and biased downwards by spring 34 whose initial compression depends on the vertical position of sleeve 32. This is set by thread 31 by rotation of the sleeve. This is achieved by a cross-piece 37 which passes through apertures 36 in the sleeve and is secured to the armature 39, so that rotation of the armature also turns the sleeve in its thread 31 to adjust its vertical position. The cover 40 is easily removable for this purpose. The armature depresses the spindle by means of a screw 47 in cross-piece 37. This screw is adjusted to leave sufficient air-gap on energization to prevent sticking. A return spring 51 is provided.
