Title: Improvements in or relating to stitch adjusting mechanisms in sewing machines
IPC: D05B27/22
Filed: 1957-10-08
Abstract: 867,805. Sewing machines. PFAFF A. G., G. M. Oct. 8, 1957 [Oct. 9, 1956], No. 31379/57. Addition to 812,298. Class 112 The arrangement for manual control of the work feed so described in the parent Specification is modified to provide for alternative automatic control of the work feed. In the original arrangement a feed-adjusting slide 17, pivoted on a fixed pin 18, is connected by a link 23 to one end of a lever 44 pivoted on a fixed pin 42. A stud 46 carried by lever 44 is disposed within an aperture 36 formed in a rotatable disc 35. Slide 17 is spring-biased to raise stud 46 into engagement with the outer edge of the aperture governing the length of forward stitch, adjustment of the latter being effected by rotating disc 36. A shaft 59, coaxial with disc 35, carries a three armed lever one arm 63 of which is connected by a spring 61 to pin 42 for biasing another arm 65 against pin 42. When shaft 59 is rotated clockwise against the bias of spring 61 the third arm 55 engages a stud 54 on lever 44 to shift stud 46 into engagement with the inner edge of aperture 36 governing the length of the reverse stitch. This arrangement is modified by extending aperture 36 to form a second portion 36<SP>1</SP> beyond the position of zero feed, and the arrangement is incorporated in a zig-zag sewing machine having nest of rotary cams comprising cams 89 governing the stitch width and a cam 88 governing the stitch length. Cam 88 co-operates with a follower 87 on an arm of a bell crank lever 86, the other arm of which is coupled by a link 82 to one arm of a bell crank lever 77. A bar 69, pivoted to the other arm of lever 77 and biased anti-clockwise by a spring 76, carries a stud 72 which normally engages the outer edge of a substantially vertical slot 75 in a lever 74 which is coupled to lever 44 and pivots with the latter about pin 42. When disc 35 is rotated anti-clockwise to position stud 46 within the aperture 36<SP>1</SP>, stud 68 on disc 35 enters a slot 70 formed in the end of bar 69 to pivot the latter clockwise. Stud 72 is thereby shifted into a slot 73 formed substantially horizontally in lever 74, whereby bar 69 is coupled to link 23 for effecting automatic control of the feed. The magnitude of the variation of the latter increases as disc 35 is progressively rotated to shaft stud 72 nearer to pin 42.

Abstract: 1356886 Visual aids for aircraft BURROUGHS CORP 7 July 1972 [20 July 1971] 31908/72 Heading G4F An optical device for guiding an observer (e.g. the pilot of a taxi-ing aircraft) along a prescribed path and indicating when to stop comprises (a) a centre line module 14 comprising two light sources arranged at different distances from a lens system so as to form a centre bar of light 20 together with another bar 18 which becomes aligned with the centre bar when the observer is in the prescribed path; and (b) a stop bar module 24 comprising at least one light source and a second lens system so arranged as to form a stop bar of light 22 which moves and becomes aligned with a stop cue 30 when the observer is in the stop position. In the device described, the light sources are provided by ground glass inserts illuminated by lamps. Fresnel lenses provide virtual images of the light sources and ribbed lenticular spreaders diffuse the light rays either horizontally or vertically. The sensitivity of the indicators may be increased by increasing the distance of the lamps from the Fresnel lenses, but this decreases the angle within which the moving hands may be observed. Coloured filters 16 colour the line bar 18 to indicate the point at which the pilot should make an initial turn. The stop bar module may include two lamps so that a stop bar may be seen whether the pilot is above or below the level of the device. A photocell 15 controls the brightness of the lights according to the ambient light. The device may be mounted on an airport terminal building to assist the docking of aircraft without ground signalmen.

Title: Improvements relating to the manufacture of photoconductive image transducer tubes
Inventor: JACOBS JOHN EDWARD
IPC: H01J29/45
Filed: 1956-10-19
Abstract: 852,281. Photosensitive devices. GENERAL ELECTRIC CO. Oct. 19, 1956, No. 31926/56. Class 37 An image transducing device is made by preforming a panel mounted layer of photo-sensitive semi-conducting material, conditioning the same to inhibit atmospheric deterioration and thereafter transferring the panel mounted to an assembly in an envelope which is subsequently evacuated and sealed and finally deconditioning the layer. A suitable semi-conductor material sensitive to penetrating rays such as X-rays is metal-activated lead monoxide, and in this case the inhibiting may be accomplished by a thin layer of lead carbonate which may be subsequently removed by electronically bombarding the layer and gettering the envelope at the same time. Fig. 1 shows a photo-sensitive layer 22 on a conductive panel 23, (which may be conducting glass if the rays are visible light, or aluminium if the rays are X-rays) in position in an evacuated envelope 16 which also contains an electrons gun 20 and means for causing the electrons to scan the layer 22. The penetrating rays are indicated as coming from 12 and contain an image 13. The photo-sensitive layer may be applied to the panel by supporting the panel face downwards over a platinum boat containing the semi-conductor material in an evacuated chamber and heating the 'boat to cause the material to be evaporated on to the layer. Alternatively, the material may be allowed to settle out of a suspension in a solution of a suitable binder such as potassium silicate, draining the excess solution and drying the panel by baking at 100‹C. in a vacuum. Another method of applying the photosensitive material is to mix it in a finely divided form with suitable lacquer and to paint or spray it on the panel. The layer comprising lead monoxide may be exposed for a time to carbon dioxide gas to form a thin protective layer of lead carbonate. Specification 847,068 is referred to.

In a " no break " power supply system comprising a synchronous motor 11 coupled to an A.C. generator 13 supplying a load 19 and a D.C. machine 15 fed from, feeding, or floating in parallel with a battery 21 which may be charged from a rectifier 23, the machine 15 is preferably nromally run as a motor supplying 10-15% of the power and the motor excitation is automatically controlled to maintain the armature current constant. The voltage across a series resistor 75 controls a magnetic amplifier 41, 43, 45, 47 which carries the D.C. voltage applied across one diagonal of a bridge network 61-64, a fixed reference voltage from a rectifier 65 being applied across the other diagonal so that normally -resistor 63 carries no current. Variation of the armature current causes a voltage to appear across resistor 63 which acts on a field regulator 27 to return the armature current to the desired value. On failure of the source, the circuit is disabled and the field winding is controlled by the load to give constant frequency, the load voltage being maintained constant by the generator field regulator 25.
