Title: Improvements in folding machines for laundry flatwork
Inventor: CRAN WILLIAM BROADBENT GORDON
IPC: B65H45/101
Filed: 1957-07-16
Abstract: 838,554. Folding fabric articles. BROADBENT & SONS Ltd., T. July 11, 1958 [July 16, 1957; July 3, 1958], Nos. 22471/57 and 21289/58. Class 42 (2). Relates to a laundry folding- machine of the type in which the leading edge of a travelling article a to be folded is lifted and gripped by a pick-up plate e under the control of two feeler arms c, d, Fig. 4; plate e is actuated by two independently controlled units which are mechanically interconnected so that both units must be activated to lift plate e to gripping position, as shown in Fig. 3, whilst when one unit is deactivated, plate e falls to a midway position q and releases its grip on the article, and when the second unit is also deactivated plate e falls to its initial position against a conveyer b. This arrangement prevents the article being trapped beneath plate e. As shown in Figs. 3 and 4, the control units consist of a long-stroke solenoid n and a short-stroke solenoid o the armatures k and on of which are connected to the ends of a lever j, the mid-point of the lever being cornected by a link i to an arm h on the pivot shaft g<SP>1</SP> of plate e. When feeler c is raised, solenoid o is energized and its armature rises, but lever j merely pivots about its mid-point and plate e does not move. When feeler d is also raised, solenoid n is also energized and plate e is lifted to gripping position. When feeler c is released, solenoid o is de-energized, but solenoid n remains energized, so that plate e falls to the midway position. When feeler d is also released, both solenoids are de-energized and plate e falls to its initial position. Air or hydraulic cylinders may be used instead of solenoids. In another embodiment, Fig. 8, feelers q, r control the flow of compressed air to two cylinders u, v, having pistons w, x respectively anchored at y to a fixed point and connected to a pick-up plate z. Again, the arrangement is such that when feeler q is raised, plate z is unaffected; when feeler r is raised, plate z is lifted to gripping position; when feeler q is released, plate z is lowered to the mid-way position: and when both feelers are released, plate z falls to its initial position. Solenoids may replace cylinders u, v.

Title: Improvements in or relating to colour television systems
Inventor: SCHAGEN PIETER
Filed: 1959-07-03
Abstract: 899,969. Colour and stereoscopic television. MULLARD Ltd. April 27, 1960 [July 3, 1959], No. 22959/59. Class 40(3) A combined colour and stereoscopic television system comprises means for transmitting on a first channel simultaneous or dot-sequential signals representing two out of three colour components of the first coloured image of a stereoscopic pair, means for transmitting on a second channel, simultaneously with the signals on the first, signals representing the remaining colour component of the second coloured image of the stereoscopic pair, and means for reconstituting and displaying said signals as superimposed or interleaved images in corresponding colours. An observer wearing spectacles, comprising for one eye a filter for the colour component(s) from the first image and for the other eye a filter for the remaining colour component from the second image, sees a stereoscopic image. Furthermore, since the brain integrates the coloured information received through the two eyes, an illusion of a complete coloured picture is created. In the preferred arrangement illustrated the transmitter employs two cameras which view the image O over paths inclined at an appropriate angle α, one camera having a signal pick-up tube Cg which produces signals representative of the green component of the left-hand view, and the other camera having two pick-up tubes Cr and Cb which produce signals representative respectively of the red and blue components of the right-hand view. The signals are transmitted simultaneously over channels G, R and B to a receiver where they cause reproduction of superimposed or interleaved images in corresponding colours. The image reproducer may comprise a "Lawrence" tube, a single-gun, stripedscreen tube, a combination of three tubes, one for each colour, or, as illustrated, a three-gun shadow-mask tube. Spectacles for viewing the reproduced image comprise a filter Fg to pass green light to the left eye and a filter Frb to pass red and blue light to the right eye. The system loses the stereoscopic effect in saturated areas, and according to a modification this is avoided by presenting finer detail stereoscopically to both eyes. Two additional pick-up tubes are associated with tube Cg to obtain the higher frequencies of the red and blue components of the left-hand view. The green channel then conveys the combined signals comprising the green low frequencies and "mixed highs" due to green, red and blue. All these signals are displayed in green at the receiver. An additional pick-up tube is added to camera Cr, Cb to obtain the high frequencies of the green component of the right-hand image and these are added to the signals in both channels R and B so as to be reproduced in both red and blue. It is stated that the signals in channel G in this modification may be employed to produce a non-stereoscopic black- and-white image.

[Class 80 (ii)] Change-speed gearing suitable for vehicles comprises two parallel shaft lines 1, 2 each line consisting of shafts positively clutchable together, and means for obtaining more speeds than there are gear pairs, all operable by a manual selector. The arrangement of Fig. 10 comprises four pairs of gears and yields six speeds, with an additional reverse. The driving shaft line 1 comprises shafts 1<b>, 1<a>, connectable by a clutch 1<c>. The driven shaft line 2 comprises shafts 2b, 2<a> connectable by a clutch 2<c>, which also entrains a pair B<4>, A4. A double clutch 1<e> entrains a pair A<2>, B<2> or a pair A<3>, B<3>, and a clutch 2<e> entrains a pair A<1>, B<1>. The gear pairs may alternatively be entrained by sliding into mesh. A one-to-one or direct drive is obtained through the pair A<3>, B<3>. An overdrive results by driving through the pair A<2>, B<2>. Two reduced drives are effected through the pair A<1>, Bl and through the pair A<4>, B<4>, respectively. The extra speeds are two triple reductions, one of which is shown in Fig. 1, through the pair A<1>, B<1>, the pair B<2>, A<2>, and the pair A<4>, B<4>. The other triple reduction is obtained by substituting the pair B<3>, A<3> for the pair B<2>, A<2>. Reversed drive is effected by sliding the gear A<1> into mesh with an idler cluster illustrated in Fig. 8, not shown, connecting to the gear B<1>. There are five forks 22, Fig. 11, on sliding rods 15 arranged around a shaft 12, Fig. 12, which is turned to select and slid axially to operate.

Abstract: 406,299. Moulding bricks &c. in hopper-and-plunger machines. RACTLIFFE, G. H. C., and LONDON BRICK CO. & FORDERS', Ltd., Stewartby, Bedford. Aug. 17, 1932, No. 23106. [Class 87 (ii).] Hollow or solid bricks, blocks or the like are made from natural clays without added moisture in hopper- and-plunger machines having a quickreturn-motion for the plunger and an initial quick forward movement followed by a slower final movement at the period of greatest pressure. Fig. 1 shows the plunger 26a at the beginning of its forward stroke, during which material supplied by the shoot 11 is separated from the bulk in the cylinder 10 and then extruded from the mouth-piece 20 over the tapered core 18 and through the converging throat 19. The plunger rod carries two other pistons 26, 27 of which 26 moves in a steam or compressed-air cylinder fitted with a slide valve 35, and 27 moves in a hydraulic cylinder connected to a pressure pump or accumulator 28, and an elevated tank 31. The initial part of the forward stroke is performed by the piston 26, the piston 27 meanwhile drawing in water from the tank 31 through the valve 34. At the point where the shoot 11 is closed by the plunger, the cylinder 25 is opened to exhaust, and the valve 34 closed, while a second valve 30 is opened to put the piston 27 into communication with the source of pressure 28, thus completing the forward stroke slowly by hydraulic pressure. The return stroke is performed by the piston 26, the valve 30 being closed and the piston 27 evacuating the water in the cylinder into the tank 31. All the valves are controlled by cams 41, 42, 43 mounted on a rod which moves with the pistons, and are connected to the various valves through lever linkages. Reference is also made to the electrical control of the valves. Means for evacuating air from the main cylinder comprise openings 23 and a vacuum pipe 21.
