Title: Improvements in or relating to printing machines
IPC: B41L47/24
Filed: 1928-08-11
Abstract: 295,404. Addressograph, Ltd., (Assignees of Duncan , J, S., and Hubbard, H. E.). Aug. 12, 1927, [Convention date]. Feeding sheets. - Magazines or other articles are fed into an addressing or similar printing machine by means of a chain which engages the underside of the lowest magazine in a stack and advances it into position to be engaged by devices for pulling the forward edge of the magazine in a downward direction to feed the magazine to printing position. As shown, the magazines in the form of a staggered pile are moved forward over a table 26 by chains 36 passing over sprockets 34, the forward sprockets being fixed on a shaft 33, which is rotated intermittently by means of a ratchet 35 (Fig. 6) actuated by a pawl 43 oscillated about the shaft 33 by a rod 41 connected to a crank pin on a, gear 4 fixed on a. rotary shaft 5. The, suction device comprises suction ports 12<1> on a hollow bar 12, Figs. 4 and 7, pivotally suspended from a valve casing 29 and rocked about the pivot by means of a rod 28 connected to a lever 9, which is oscillated about a pivot 10 by a cam on the shaft 5. The bar 12 at its upper end is formed as a sleeve provided with valve ports 56 and rotatable within a slotted lever so that the pivotal movement controls the suction from a suction pipe 30. The suction device draws the magazine downwardly between feed rollers 24, 16<1>, the former extending through slots in thefeed table 26 and engaging the bottom magazine, and the latter being carried by arms 16 rocked about a pivot 15 by a cam. on the shaft 5, so that the roller 16<1> is periodically moved towards the roller 24 to grip and feed the magazine to conveying-bands which feed the magazine to printing position. As the suction device is drawing the magazine down, fingers 13 oscillated about a pivot 11 by means of a cam on the, shaft 5 swing up and engage the pile to prevent more than one magazine being fed. The amount by which the pile of magazines is fed forward each time is controlled by means of a series of fingers 54, Fig. 6, which are rocked about a pivot 50<1> by the advancing magazines and oscillate a lever 49 about a pivot 49<1> into a position where a roller 48 on the lever 49 is more or less moved away from a cam 47 on the shaft 5. This controls the effective stroke of the cam, and therefore the amount of oscillation about the shaft 33 of an arm 53 connected by a rod 52 to the lever 49. A cam on the end of the arm 53 is adapted to engage a pin 43<1> on the pawl 43 to raise the pawl away from the ratchet 35 during part of its movement and so to vary the amount of rotation of the shaft 33 and therefore the movement of the feed chains 36. Specification 295,403 is referred to.

Abstract: 277,330. Westinghouse Electric & Manufacturing Co., (Assignees of Coleman, J. B., and Conrad, F.). Sept. 13, 1926, [Convention date.]. Condensers.-A piezo-electric crystal is held between relatively-adjustable parallel electrodes secured to internal and external shoulders on an insulating support, so that the electrode spacing and parallelism are unaffected by changes in the dimensions of the support due to temperature variations. Fig. 2 shows in cross-section a preferred construction. The insulating base 20 is of circular form with a central opening 21,.and has an interior shoulder 22 and an exterior shoulder 28 both in the same plane. The electrode 25 is adjustably supported in a metallic plate 23 screwed to the interior shoulder. The other electrode is carried by a cap 29 screwed to the exterior shoulder. The crystal 30 is of rectangular shape and lies loosely in a rectangular recess in the base 20 so that it does not rotate when the electrode 25 is adjusted by the screw 24. The base is mounted by brackets 31, one of which is secured by screws to the cap 29, the other being attached by screws 33 and distance block 34 to the plate 23. Materials having low temperature co-efficients of expansion are used for the insulating and metallic parts. The opening 21 may be filled with a sealing compound after setting the electrode spacing for a given frequency. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a construction shown in Fig. 1 (Cancelled), in which the crystal 4 is held between overlapping electrodes 1, 5, one of which is directly attached to the base 2, the other having a screw-and-slot adjustment 9, on a bracket 6. Alteration of the distance between the fixing screws 3, 7, results in unobjectionable parallel sliding movement of the electrodes 1, 5, whilst variation in thickness of the base 2 produces no relative movement. This subject-matter does not appear in the Specification as accepted.

Abstract: 895,937. Side-delivery rakes. VAN DER LELY N.V., C. July 22, 1958, No. 23584/58. Class 6(3). A tractor-mounted side-delivery rake of the oblique rake-wheel type is capable of movement to several working positions corresponding to side-delivery, tedding and swath-turning, and in the sidedelivery position the rake-wheels work a swath which is laterally displaced from the track of the tractor 9 so that the latter does not run over the crop to be turned. The implement comprises a frame having a part 1 which is mounted on the tractor draught-links 6, 7, 8, and a part 2 which is movably mounted on the part 1 and carries the rake-wheels 19-22. The part 1 consists of U-shaped tubes 10, 11 terminating in two vertically-spaced coaxial bearings 13, 14. The part 2 consists of two parallel beams 15, 16 pivotally inter-connected by tubes 23, 24 to form a deformable parallelogram having apices 25 28, the' beams 15, 16 having extensions 17, 18, outside the parallelogram, which carry the rake-wheels on spring- loaded cranks 46. The parallelogram is secured against deformation by an arcuate strip 29, carried by the beam 15, to which strip the beam 23 is pinned at 33. For swath-turning, the pin 33 is removed and the parallelogram swung into the dotted position so that the rake-wheels form two groups of two 19, 20 and 21, 22, laterally spaced. The beam 15 is integral with two U-shaped beams 34, 35 which terminate in bearings 37, 38 coaxial with the bearings 13, 14 on the frame-part 1 so that the frame-part 2 can be swung bodily around the part 1 into the position shown in Fig. 4, without deformation of the parallelogram, the frame parts 1 and 2 being locked together in both positions by a stay 44 engageable with apertured strips 40, 67 and with lugs 42, 65, on the frame-part 1. In the position shown in Fig. 4, each rake-wheel operates independently so that the device is a tedder. Specifications 895,938, 895,939 and 895,940 are referred to.

Title: Electrical supply circuit for a hollow cathode lamp
IPC: H05B41/30
Filed: 1973-05-17
Abstract: 1429338 Automatic current control RANK ORGANISATION Ltd 9 May 1974 [17 May 1973] 23602/73 Heading G3R [Also in Divsion H2] A circuit for maintaining a constant current through a discharge lamp L comprises a transistor T and an operational amplifier A. The lamp is supplied with a D.C. voltage VR and a potentiometer P, connected to a squarewave generator G, sets the value of the current flowing through the lamp. If the current through the lamp tends to change due to changes in the lamp temperture or in the value of the voltage VR, the voltage VI across a resistor R also changes. The output of the amplifier A therefore changes to adjust the conduction of the transistor T so that the lamp current remains constant. A light emitting diode LED visibly indicates the lamp current.

Title: Process for the manufacture of polyesters of terephthalic acid
Inventor: MUNRO NEIL
IPC: C08G63/78
Filed: 1954-08-16
Abstract: Fibre-forming polyethylene terephthalate is made by heating mono-hydroxyethyl terephthalate at a temperature above its melting point and preferably under reduced pressure.  A small amount of a diol, e.g. bis-(betahydroxyethyl) terephthalate, may be added to the monohydroxyethyl terephthalate before polymerizing.  The mono-hydroxyethyl ester is made by reacting ethylene oxide with terephthalic acid in an aqueous medium (see Group IV (b). Specifications 590,451, [Group IV], and 623,669, [Group IV (b)], are referred to.ALSO:Monohydroxyethyl terephthalate is made by reacting ethylene oxide with terephthalic acid in an aqueous medium, preferably in presence of sufficient of a base or an alkaline reacting salt of an alkali metal to convert all the terephthalic acid to the mono alkali metal salt.  As a catalyst a terephthalate may be used, e.g. a terephthalate of an alkali metal, ammonium, pyridine or N,N-dimethylaniline.  The catalyst may be formed in situ by interaction of a proportion of the terephthalic acid with a substance which forms a water-soluble terephthalate therewith, e.g. sodium or potassium hydroxide, sodium borate, ammonia, ammonium salts or amines.  In the example, 1 mol. of terephthalic acid suspended in water containing 1 mol. of potassium hydroxide was heated in a water bath and saturated with ethylene oxide till complete solution was obtained.  After boiling off the residual ethylene oxide the solution was cooled and sulphuric acid and water added to give a paste.  This was filtered off, water washed and extracted with boiling water.  The crude monohydroxyethyl terephthalate which separated on cooling the extract was recrystallized from water.  Specifications 590,451, [Group IV], and 623,669 are referred to.
