Patent GB-709018-A (GB)
Title: Paper feeding mechanism in adding machines or the like
IPC: B41J19/84
Filed: 1951-05-22
Abstract: 709,018. Typewriters &c. AKTIEBOLAGET ORIGINAL-ODHNER. May 22, 1951 [June 1, 1950], No. 11976/51. Class 100 (4) A line spacing mechanism for adding and like machines normally feeds a platen 1 one or more line spaces dependent on the manual setting of a line-spacing lever 6, and shifts automatically from single line spacing to twoline (or another multiple line) feeding when certain operating keys, e.g. totalling keys, are depressed. The platen 1 is mounted on a spind 2 2 and rotated by a ratchet wheel 3 by either a pawl 4 effecting a single line spacing at each machine cycle or by both the pawl 4 and a pawl 5 in successive movements. The operation of pawl 5 only occurs when a multiple line space is to be effected and occurs if (a) the lever 6 is set to multiple spacing or (b) the lever 6 is set to single spacing and a total taking cycle occurs. At each machine cycle, pawl 4 advances ratchet 3 one space and an actuating member 25 moves upwards and engages a roller 16 on a shaft 15 attached to a feeding crank 8 swinging about the spindle 2. The crank 8 has a large aperture 14 through which passes a shaft 9 at one end of which is fixed the pawl 5. The other end of the shaft 9 bears on a cam plate 12 against which it is held by a spring 10. When the lever 6 is set for single line spacing a pin 19 is snapped into a recess 21 in a slot 20 in the cam plate 12 pivoted at 13 to the platen carriage so that the shaft 9 is held on the raised part of the cam plate 12 and is positioned so that it limits the swing of the pawl 5 which fails to engage the feeding wheel 3. When the lever 6 is rocked for multiple line spacing, the pin 19 is snapped into a recess 22 as shown in Fig. 2. When actuation of the member 25 now occurs, the crank 8 is rotated and the shaft 9 springs into a recess 12a on the cam plate 12 causing the hook 5 to engage the feeding wheel 3. When the lever 6 is set for single-line spacing and a total-taking key is depressed, an arm 24 swings to engage a roller 23 on the cam plate 12 which is swung anti-clockwise to allow a movement of the shaft 9 when the crank 8 is operated by the actuating member 25, so that the pawl 5 engages the ratchet wheel 3 to effect an additional line space. Pawl 4 operates after printing but the operation of pawl 5 may occur either before or after printing.

Title: Moulding method and apparatus
IPC: B29C33/36
Filed: 1962-03-29
Abstract: 964,047. Moulding machines. UNITED STATES RUBBER CO. March 29, 1962 [May 15, 1961], No. 12043/62. Heading B5A. Moulding apparatus comprises a channel 5 mounted on a frame, a number of moulds 46a-46k, 47a-47k, which can be inserted at 48 into the channel and are slidable along it to an output end 24 where they may be withdrawn at 52. The inlet portion 22 consists of four walls (two only, 35, 36, shown) rigidly connected to each other and to a plurality of longitudinally extending angle members which are also connected to wall members 29, 30 of the outlet end 24. A heated enclosure 15 surrounds a portion of the channel 5. In operation, assuming the channel 5 has been previously loaded with mould plates 47a-47j, 46b-46k, the mould plate 46k is ejected through opening 52, and by actuation of reversing valve of the reciprocating means (Fig. 1, not shown), the plunger 41 commences a compression stroke, pushing cavity mould plate 47a to the right, and by friction causing the entire channel 5 to move until the end face 24a of the outlet portion abuts a shoulder 42a of a steel block 42 rigidly supported on support leg 4. As the movement continues, the mould plate 47j abuts steel block 42, the column being then under compression. Via the reversing valve the piston is withdrawn, and by friction and engagement of the plunger with hooks 41a the entire channel 5 is shifted, opening a gap 45. The mould plate 47j can now be removed, an imperforate mould plate 46a inserted at 48, and moulding composition 50 added via aperture 49. The plunger 41 is then moved forward again, as previously, and the moulding compound fills the cavity of cavity plate 47a, the excess compound forming a pad 56 between adjacent mould plates. Eventually after two or more cycles, the pad 56 meets an aperture in the wall of portion 22 and during a compression stroke is squeezed out of the channel and into a receptacle. As the compound is cured, expansion of the material forces out some more flesh which is sheared from the edges of the moulds by the leading edge 59 of the outlet portion 24 and drops into another receptacle. An ejection fixture 54 may be provided adjacent the moulding apparatus to remove the cured articles from the cavity mould plates. Specification 766,816 is referred to.

Abstract: 332,559. Dicker, S. G. S., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). April 22, 1929. Television.-Means are provided for synchronously moving one or more of the parts which determine the plane of the strips on the image at right angles to the length of the stripe. A television transmitter comprises an image 1, a focusing lens 2, a scanning disc 3 and a light-sensitive cell 5, and in order to move the strips in the manner desired, the shaft 4 of the disc 3 may be rotated eccentrically by a shaft angles to the direction of motion, or the optical system 2 may suffer a periodical movement, or the disc may be rotated eccentrically by a shaft 7 in which case the disc is furnished with a double spiral of holes. In a modification of such an installation, the scanning disc, Fig. 3, has two spirals, only one of which is shown, which are radially shifted relatively to each other to obtain the cyclical movement of the elemental strips, and each spiral is divided into separate groups of holes such as 1 - - 6 and 7 - - 12, the group 7 - - 12 dovetailing with the group 1 - - 6. This has the effect of reducing the flickering frequency. The receiver is adapted to act in the same way as each of the transmitters described.

Abstract: 768,828. Cables. SIEMENS & HALSKE AKT.-GES. April 29, 1955 [April 30, 1954], No. 12517/55. Class 36. A high-frequency, multi-layer transmission line is constructed from a plurality of conductor elements which are so dimensioned and arranged that the mutual coupling impedance (i.e. the ratio of the voltage induced in an individual element to the current flowing in the adjacent element and producing that voltage) has substantially the same dependence upon frequency as the high-frequency impedance, even at frequencies at which the thickness of the elements is greater than the depth of penetration of the current. The arrangement is such that the attenuation is low and substantially independent of frequency over a wide frequency range. The elements in a layer and the layers themselves may be spaced apart by a distance greater than the thickness of the elements, by a dielectric such as polyethylene or polystyrene. Some or all of the elements may be inductively loaded as by being enclosed in magnetizable material or having such material disposed therebetween or between the layers. Fig. 4 shows conductor elements 12 separated by insulating members 13 and insulating layers 15, 16 between which additional conductive members 14 may be disposed. In Fig. 5 the conducting elements 12 are laid in grooves 18, or pressed into the surface of layers 17 of foamed material. The core 10 may be insulating or conducting, in which case it may be used for supplying current to repeaters.
