Title: Adjustable offset scanning device
IPC: B23Q35/128
Filed: 1960-09-28
Abstract: 898,516. Photo-electric line followers. BRITISH OXYGEN CO. Ltd. Sept. 28, 1960 [Sept. 30, 1959], No. 33361/60. Class 40(3). The invention relates to a photo-electric scanning device for automatically following a path denoted by a line of contrasting reflection on the surface of a drawing for the purpose of controlling a machine implement, for example the torch in a flame-cutting machine, to follow a similar path on a workpiece, and is concerned with means for introducing an adjustable amount of off-set in the implement path so as to allow for such factors as the cross-section of the cutting flame whereby the contour of the finished workpiece may be made identical in size with the original drawing. In Fig. 2 a photoelectric scanning device comprising an oscillating photo-electric cell assembly 40 is moved along a line 27 on a drawing by a constant speed driving wheel 26, the wheel supports 32 being mounted for rotation about a vertical axis by a motor 34 which is controlled by information obtained from the photo-electric cell so as to steer the wheel to cause the device to follow the line. The housing 45 of the photo-electric cell assembly is also mounted for rotation about a vertical axis and is coupled to support 32 by gearing 47, 48, 49. The arrangement is such that the path of oscillation of the cell remains transverse the line or at a constant angle thereto. The scanning device is coupled mechanically to a carriage for the torch of a flame-cutter, Fig. 1 (not shown), and causes the torch to trace out a path on a workpiece similar to line 27. In the photo-electric cell assembly a lens 56 forms an image of the line and the photo-electric cell is supported so that it may be oscillated laterally of the image under the control of coils 43 energized by alternating current, for example the mains supply. The signals from the photo-electric cell are fed to an amplifier circuit 35 incorporating a synchronized gating circuit, and the signals produced by a scan of one side of the line are separated from the signals produced by a scan of the other side of the line. The two groups of signals are then subtracted from each other and any remainder employed to operate motor 34 to steer wheel 26 to centralize line 27 under lens 56. In accordance with the invention, the support 55 for lens 56 is carried by a pair of trunions 58, Fig. 3, so that the support axis may be inclined to the vertical in a direction laterally of line 27. The extent of inclination is determined by an adjustable screw stop 61 carrying a calibrated dial 61a against which the support is urged by a spring 62. Since the scanner functions to centralise line 27 under lens 56, any inclination imparted to support 55 results in the scanner being off-set from the line and a corresponding off-set being given to the flame-cutting torch.

Title: Improvements in radio signalling systems
IPC: H01Q11/04
Filed: 1928-11-15
Abstract: 300,591. British Thomson-Houston Co., Ltd., (Assignees of Alexanderson, E. F. TV.). Nov. 15, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Aerials; directive signalling; fading, preventing.-A directive aerial system for short-wave working is built up of units such as shown in Fig. 1. Each unit comprises two interposed zig-zag conductors 1, 2. The conductor 1 comprises five elements a', d<1>, b<1>, e<1>, c<1>, whilst the conductor 2 consists of similar elements a, d, b, e, c, the combination resulting in two parallel " radiators " a, b', c and a<1>, b, c' carrying in-phase current, divided by two vertical non-radiating elements d, d<1>, and e, e' in which the current is out of phase. Each unit is ied from a high-frequency source 4 through feeders 3 which are connected across an insulating member at the mid-point of the elements b, b'. Each element is preferably a half-wavelength oscillating unit, but as the aerial system as a whole is free from distinct tuning means it is capable of operation simultaneously on different wavelengths, for the purpose of overcoming fading effects. The unitary system shown in Fig. 1 may be multiplied and arranged in different settings as shown for instance in Figs. 5, 7 and 10. In Figs. 5 and 7, the effective plane of radiation may be varied by adjusting the inclination of the supporting-frame through guy-ropes 20, 21, Fig. 5, on the inclination of the supporting cable 26 relatively to the ground. The radiating units may be backed by similar arrangements of non- energized conductors which act as reflectors. The plane of polarization of the radiated wave mav also be determined by the angle between the plane of the antennae-support and the surface of the earth. In Fig. 10 two groups of radiators are arranged end to end in a vertical plane. They are insulated from each other at the point 34, and are energized from a common supply 4 through feeders 32, 33. The upper and lower parallel radiators may be separated by any integral multiple of half a wavelength. When the vertical connectors d, d<1> and e, e<1>, Fig. 1, are a full wavelength, the current in the lower radiator 2 is in the reverse direction to that in the upper radiator 1. The radiation is then at right-angle to the plane of the antennae and is directed 30‹ upwards to the horizon. 'The aerial system is applicable to directive reception as well as transmission.

In an automatic aircraft pilot the relative position of electrical contacts operated by a roll detector to control the ailerons is automatically adjusted by a turn detector. In Fig. 1 the position of aircraft ailerons (not shown) may be controlled directly through a chain 46 and cables 50 by rotation of a handwheel 42 secured to a shaft 36 of a dual control system. For automatic control, a lever 88 is operated to rotate a cam 90 moving a push-rod 92 to place a ring gear 78 into frictional engagement with a collar 80 on shaft 36 so that a reversible electric motor 64 is coupled through gearing 76, 78 to shaft 36. Motor 64 is then operated automatically in the appropriate direction to maintain level flight under the control of a contact carried by a gyro horizon (not shown), within a casing 108, moving relative to opposed contacts carried by casing 108. Casing 108 is mounted in a bearing 102 so that it may be rotated by cables 50 through springs 176 and lever 170 to provide mechanical follow-up. A predetermined bank for a desired turn may be produced by operating a knob 166 which adjusts the position of casing 108 through a flexible shaft 154 and gearing 168, 128. To provide more sensitive control during straight flight a rate of turn gyro within casing 188 operates contacts (not shown) controlling a reversible electric motor 134 which adjusts the position of casing 108 through gearing 140, 144, 148, 126. This control is automatically disconnected upon operation of knob 166 to produce bank. Interconnection of the rudder with the aileron control system to produce a co-ordinated turn is referred to.

Abstract: 438,755. Moulding cement &c. blocks &c. by tamping and shaking machines. NINGELGEN, C., 93, Teckstrasse, Cannstatt, Stuttgart, Germany, and GEDDES, R. W., 106, Regent Street, London. Nov. 26, 1934, No. 34007. [Class 87 (ii)] A tamping machine for moulding bricks, slabs, blocks and the like from gravel, sand, slag, pumice or cement comprises common driving means for causing a reciprocating feeding box 3 to convey material from a hopper 1 to a mould 17, shaking the mould, compressing the material by a tamper or drop stamp 40, raising the mould and stamp and removing the moulded slab, and the box 3 may be given a short additional reciprocation while it is over the mould or the slab may be removed by a transport device provided with means for raising it in contact with a board 7 whereon the slab lies. A main drive shaft 8 carrying a cam 18 provides the common drive. Endless chains 5 carry the base boards 7 for the mould and are intermittently driven through pawl and ratchet gearing from an eccentric 9 on the shaft 8. As the box 3 moves from a tube 2 leading from the hopper 1, a plate 24 closes the tube. At the position for filling the mould, the box 3 is given the short reciprocation by cam portions 25 to shake all material from the box into the mould. The box is moved back to the tube and the mould is shaken by being raised and dropped by a roller 38 on a lever 37 operated by cams 34 on an arcuate portion of a cam disc 32 on the shaft 8. The drop stamp is normally held raised by a pawl 47 loaded by a weight 49, but, on release, is moved for tamping by levers 42, 44 and a roller engaged by portions 51, 52, 53 on the cam disc 32. Two or more successive falls of the stamp are effected according to the number of portions 51, 53. After tamping, the drop stamp remains down while the mould 17 is raised to expose the article by a rod 54 operated from an eccentric 57 on the shaft 8. The stamp is raised and the moulded article removed on the board 7, the transport device consisting of moving ropes 62 which are raised up to engage the board by rollers 66 on arms 65 operated from a cam 72 on the shaft 8. Simultaneously, a further board 7 is fed forward by the chains 5. The box 3 may be provided with rollers running on rails and may have attached to it a scraper 26 adapted to strickle the material in the mould on the return movement of the box. The scraper may be mounted on a pivoted arm carrying a roller engaging the rails which are upturned at one end so that the roller and scraper are raised slightly at that end of the mould remote from the hopper. The loosely packed material at that end is thus allowed to heap up, whereas closely packed material at the other end is strickled.
