Title: Improvements in or relating to visual display apparatus
Inventor: ACTON JOHN REGINALD
IPC: G02F1/17
Filed: 1964-11-30
Abstract: 1,132,695. Moriogrammic signs. PLESSEYUK Ltd. 19 Nov., 1965 [30 Nov., 1964], No. 48503/64. Heading G5C. Visual display apparatus comprises a thin layer of material whose optical absorption varies in response to an electric field or temperature, with means for causing such varation at a selected region, and monochromatic illumination for the layer, of wavelength corresponding to the absorption edge of the absorption spectrum of the material. The material may be a semi-conductor, in particular selenium used with the sodium D line, or a mixed II-VI compound such as cadmium sulpho-selenide, the composition of which is chosen to match a chosen light source. Certain glasses, points, dielectrics, and ferroelectric materials can also be used. The light may be polarized as well as monochromatic. " In-line " indicators may be made by arranging selective heating of dots or strips in an array, or by superposing a number of heater elements each the shape of a symbol to be displayed, e.g. by evaporating a heater through a mask on to a substrate, then evaporating an insulating layer, then a second heater, and so on, followed by a light reflecting layer and a selenium layer. The device is front-lit by a sodium lamp, and viewed from the front. Energization of any heater will cause the corresponding symbol to appear dark on a light background. A crossed array device may comprise a layer of cadmium sulphide sandwiched between the x and y electrodes, potentials being applied so as to increase (or reduce) the field across the layer at the intersection of selected electrodes, producing a light or dark spot. Alternatively, absorption edge shift may be produced by the thermal effect of current passing between the selected electrodes, e.g. through a transparent heater element such as a tin oxide film connecting the electrodes, or through a suitably treated cadmium sulphide layer. Fig. 4 shows an image intensifier or converter, comprising a back conductor 4, photoconductive layer 6, absorbing layer 7, reflecting layer 8, controlled absorption layer 9, and front conductor 5, used with monochromatic light source 11. A potential is applied across conductors 4 and 5. When the back is dark, the photoconductive layer 6 has a high impedance, and the field across layer 9 is small. Under incident image radiation 10, layer 6 is of low impedance where irradiated, and the field across layer 9 is correspondingly increased, to produce an image visible to the observer 12.

IPC: D04H13/00
Filed: 1962-12-27
Abstract: A covering material for laundry presses and ironers comprises a metal wool mat with a thin non-woven, non-metallic fibrous layer on one or both sides.  A further woven layer of cotton or flannel may be applied.  The non-metallic layer may consist of a mixture of polyester fibres and cotton, woollen, or cellulose fibres and may be impregnated with water repellant substances.  The layers may be felted together by passing the webs through plain or grooved rollers and may be needled to interlace the fibres.  The covering may be laminated before being applied to a laundry roll, or may be formed by winding the skeins direct on to the roll, in which case a prior layer of wire mesh, entangled metal wool or a series of narrow laps is applied first.  Several layers may be applied and an outer covering of cotton or flannel cloth may be provided.  The needling of the layers may be accomplished by passing the webs beneath a row of needles extending across the width thereof and registering with an apertured plate beneath the webs (Fig. 4, not shown).

Filed: 1973-10-24
Abstract: 1444639 Delivering and feeding sheets RICOH K K 24 Oct 1973 [25 Oct 1972] 49469/73 Heading B8R [Also in Division F2] A sheet is fed from a facsimile recording apparatus 20, Fig. 3, to a developing apparatus 40 by two pairs of feed rollers 1, 2 and 5, 6 rotating at the speeds of the respective apparatus 20, 40, the pair 5, 6 rotating faster than the pair 1, 2. The rollers 1, 2 rotate continuously, while the rollers 5, 6 are initially stationary and are driven through a friction clutch comprising a drum 16, Fig. 4. In operation, when the leading end of a sheet has almost reached the rollers 5, 6, it engages a rod 10a to close a switch 10 to momentarily energize a solenoid 41 and allow the drum 16 and thereby the roller 12 to be rotated through a small angle so as to grip the leading end of the sheet and stop. Continued rotation of the rollers 1, 2 causes the sheet to form a loop 3a which, when it reaches a predetermined size, actuates a switch 44 to energize the solenoid and allow the roller 12 to be rotated until the trailing end of the sheet releases the rod 10a to stop the drum 16. Alternatively, the rollers 1, 2 are driven intermittently by a stepping motor, the driving pulses to which are counted by a counter which causes the momentary energization of the solenoid 41 when a predetermined number of pulses have been counted.

Title: A circuit arrangement
IPC: H03K5/02
Filed: 1964-12-04
Abstract: 1,040,810. Transistor pulse circuits. BOFORS A.G. Dec. 4, 1964 [Dec. 4, 1963], No. 49548/64. Heading H3T. [Also in Divisions F3 and G1] A signal responsive circuit, more particularly for a wire-guided missile control circuit, has means for momentarily unceasing its supply voltage when the unwanted in-phase component of the signal between the input terminals cause the potential at an input terminal to approach too closely to a supply terminal potential. The control current passes between terminals G and E of Fig. 2 and since it may be of either polarity it is passed to the input resistor through a fullwave rectifier which produces an output voltage always of one polarity. This voltage controls a long tail pair T10, T12 connected to supply terminals U + and U - and which produces an output pulse at H at each interruption of the input current. The voltage at terminals G and E may approach closely the supply voltage U - and to ensure correct operation a pulse is supplied at T from unit 1 when this occurs and this causes a transistor T17 to cut off and so momentarily increase the negative potential applied to the long tail pair via resistors 107 and 109.

The device comprises a series of members 18 which are pivoted about respective shafts 20 from the broken line position 18a Fig. 2, into the path of the coils to hold them up at a signal from a pre-settable length measuring means while wire guides 19, similarly mounted on the shafts 20 are movable in a horizontal plane parallel with that of the members 18. As the guides are moved from the broken line position 19a, Fig. 2, the guide nearest the wire draws it fowards the associated member 18, a blade 23 on the guide cooperating with a blade 26 on the member 18 to shear the wire. Each member 18 is fixed to a sleeve (33) rotatable about its shaft 20. Pinions (36), (36a) also fixed to the sleeve mesh with racks 40, 40a repectively. One rack 40a is driven by a double acting ram 42 and via alternate racks 40, 40a moves all the members 18 simultaneously. The ram 42 is actuated by a signal from the pre-settable length measurer (not shown) when the drum is full. The guides 19 are similarly mounted on a sleeve (35) and similarly moved by a double acting ram 45 via racks 43, 43a. Rollers 46 mounted to rotate on an eccentric shaft (47) Fig. 3 (not shown) hold the racks against flanges on the sleeves (33), (35). When the members 18 reach their coil-catching position, a stop 50 on a rack 40 contacts a switch 51 actuating the ram 45. Engagement of a stop 52 on a rack 43 with a switch 53 reverses the ram 45 and starts a conveyor 54 which removes the full drum 3 and feeds in a new drum 3a. If the members 18 and 19 are not moved out of their solid line positions, Fig. 2. after shearing, switches 57, 58 are not actuated by stops 50, 52 and an audible warning is given or the machine is stopped. The automatic operation may be overriden and the rams manually controlled to remove a drum before it is full.  The wire is initially fed to the capstan 12 via braking means 5, 6 and pulleys 7, 8 on a hollow shaft 9 rotated by a motor 10.

Clothing feed apparatus for a mangle comprises clothing support means 116, which extend transversely of continuously driven belts 111 and are reciprocable in the direction of movement of belts 111 to deposit clothing articles on the belts 111, feed means e.g. conveyer belts 110 associated with support means 116 being driven intermittently at a speed higher than belts 111. Adjacent conveyer belts 110 which are driven independently of the mangle, is a roller 99 which, as well as belts 111 and further adjustable belts 112, 113, is driven by the mangle drive, belts 112, 113 being driven faster than belts 111 but slower than the mangle. Light gates F01, F02 each comprising a light source and photocell are disposed respectively below roller 99 and belts 110, and between belts 110 and 111. Horse 116 comprises arms 116a with a relatively non-slip covering 117 and at their ends one or more guide rollers 116c running on an adjustable guide or guide's 120 so that as horse 116 moves leftwards towards belts 111. At the ends of a pressing roller 104 are guide rollers 104a which run on guides 121 and each end of its spindle is carried in a stirrup pivoted to part 116b of horse 116 so that horse 116 and rollers 104 are reciprocated together, e.g. by an hydraulic ram. Scraper belts 118 run round roller 104 and another roller or wheels 60. In front of belts 111 are brush belts 130, a vertically adjustable idler roller 130a and a pivoted bow 133 which together stretch the clothing articles transversely. In operation, when the mangle is switched on and belt system 111 to 113 and roller 99 are driven and control elements become active, an article is placed on horse 116 and its rear part will interrupt light barrier F01. When horse 116 and roller 104 are moved to the left, Fig. 2, to drop the front of the article on belts 111, belts 110 are started when horse 116 reaches its leftward limit. Horse 116 and roller 104 return to their initial position, guides 120 being raised to hold the horse clear of the belts. The rear of the article passes rapidly over belts 110 into gate F02, the drive to belts 110 being discontinued, after a delay, when gate F01 is cleared. A second article is then placed on horse 116 and its rear part interrupts gate F01 so that the front part is deposited on top of the first article on belts 111. Belts 110 do not start until after an interval after the first article has cleared gate F02. When double articles with facings and the like are to be introduced to the mangle, a special control producing a brief stoppage of belts 110 is brought into action to allow time for adjustment. Horse 116 may be hinged out of operation.
