Title: Improvements in or relating to circuit arrangements for use in an automatic signalling system
IPC: H04Q3/00
Filed: 1962-11-16
Abstract: 987,089. Automatic exchange systems; circuits employing bi-stable magnetic elements. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Nov. 16, 1962 [Nov. 20, 1961], No. 43461/62. Headings H3B and H4K. A subscriber's line circuit comprises two magnetic cores K1, K2 whose direction of saturation is reversed, in the case of K2, only for full loop current, and in the case of K1 for any line current greater than the maximum permissible leakage current. The core states are tested by pulses and an alarm is given if only K1 has its direction of saturation reversed. When a scanning pulse at time P 1  is applied to the pair of cores, any core having a reversed state causes a pulse to be emitted to bi-stable circuits 31, 28. If 28 only is set then at P3 AND gate 29 is opened and an alarm 30 is thereby operated. If, however, bi-stable circuit 31 is also set then at P2 it resets 28, thereby inhibiting the alarm. The cores may be of different dimensions or materials or have a different number of turns in their windings in order to cause them to change their magnetic state for the different values of current.

Title: Seat belt retractor
IPC: B60R22/41
Filed: 1975-10-28
Abstract: 1525576 Seat belt retractor GATEWAY INDUSTRIES INC 28 Oct 1975 44366/75 Heading A3V Spindle 49 is journalled in support 13 to rotate with reel 16 and ratchet wheels 32 biassed by spring 70. Spring 131 pushes rake disc 135 and hence inertia wheel 100 towards reel 16, spokes 105 moving in grooves 115. A sharp pull, either intentional or in an accident, on the belt after it has been protracted causes wheel 100 (braked by disc 135) to lag in rotation reel 16 and be moved away from the reel, a tooth 150 on wheel 100 pushing finger 93 to move pawls 26 into ratchet teeth 29 engagement against the bias of spring 83. Wheel 100 by the bias of spring 131 returns adjacent the reel and spring 83 moves pawls 26 and tang 160 outwardly whereupon the tang snaps into notch (163) on flange 155 of wheel 100 preventing further pawl disengagement. Thus the belt is held tensionless about the wearer, a fast pull on the belt e.g. during an accident causing pawls 26 to again fully engage teeth 29. A slower i.e. intentional pull on the belt moves wheel 100 releasing tang 160 and thence pawls 26. If tang 160 is omitted, so is the tensionless feature. In Figs. 10-19 (not shown) spring (220a) biases ring (215) towards ratchet wheel 32, pins (216) moving in grooves (209) in member (201). Cylinder (219) rotates with ring (215) and a notch (229) cooperates with a tang (230) on pawl (200) providing a tensionless feature. Spring (255) pushes brake disc (249) and inertia wheel (214) towards ratchet wheel 32. Initial belt protraction moves tabs (259) on brake disc (249) to abut shoulders (261) on cover (193) to prevent inertia wheel (214) moving from ratchet wheel 32 sufficiently to enable teeth (231) on wheel (233) to move pawl (200). Thus after an initial slight protraction, a sudden belt jerk does not prevent further protraction. As the belt is buckled, its slight retraction aligns tabs (259) with openings (263) and thereafter allows pawl operation. Shoulders (261) may be sloped so that fast initial belt protraction overrider the last mentioned feature.

Abstract: A flame produced by the combustion of an intimate mixture of hydrocarbon fuel and oxygen, the latter being present in an amount in excess of stoichiometric, is directed towards the surface of a bath of iron, combustion being maintained throughout the refining operation.  It is stated that in this way a large excess of oxygen may be used without the production of significant amounts of fume. The process is applicable to open-hearth and electric furnace steelmaking processes in addition to converter processes.

The safety belt dispensing and re-reeling apparatus of Figs. 3-9 of Specification 1068344 is provided with a device 41 or 42 sensitive to belt-acceleration to trigger the belt locking device, comprising a pawl 40 engageable with a ratchet wheel 31 fixed to the belt reel, which through movement of a bob weight (not shown in the figures) is sensitive to acceleration, deceleration etc., of the vehicle. Each device 41 or 42 consists of a piece of wire extending freely through a bore in a ratchet tooth and being rotated by centrifugal force when belt acceleration reaches a predetermined value into a position in which it tips the pawl 40 into engagement with a ratchet tooth. A second embodiment of triggering device (Figs. 3 and 4 not shown) is moved into triggering position mainly by inertia. Figure 6 shows a further triggering device 101 which rotates in the direction C when the ratchet wheel 77 is rapidly rotated so that a tooth 104 on the device deflects the pawl 96 into engagement with a ratchet tooth, a resilient tail portion 105 engaging a shoulder 106 on the wheel to prevent damage to the tooth 104.

A method of printing a web A of a material such as fabric in repeat lengths by means of a stencil S1 comprises applying the stencil in a frame S to the web as it moved continuously and at a constant speed in its longitudinal direction, moving a scraper, wiper blade, or squeegee R transversely across the stencil to effect printing, moving the stencil away from the web, displacing it in the direction opposite to the direction of movement of the web, and re-applying the stencil to the web in correct register with the previously printed design. The stencil may be moved rearwardly at the same speed as the web moves longitudinally and in this event it is moved rearwardly half a repeat length at a time. The web may be secured to a backing sheet and conveyed by an endless band. One guide rail may be constructed as an endless conveyer for the web while a parallel guide rail moves in the opposite direction and forms a cable for the stencil which is adjustably mounted in a carriage. The stencil S1 is movable within the frame S to obtain the proper alignment for printing and may be exchanged for a further stencil.
