Title: Improvements in pickers for looms for weaving
IPC: D03D49/36
Filed: 1927-03-10
Abstract: 289,218. Percival, H. March 10, 1927. Pickers.-To avoid the necessity of steeping loom pickers in oil, they are made from buffalo hide impregnated with glycerine after the removal of the hair and after the lime with which it has been treated have been removed by scudding or scraping, or by tumbling in a rotating drum, any remaining lime being neutralized by spirits of salts. The hides are then placed in a tumbling drum filled with glycerine. The treated hides are then dried and cut into blanks for folding into pickers.

Title: Means for feeding shoe stiffener blanks into machines for moulding the same
Inventor: FORSTER HENRY ATKINSON RONALD
IPC: A43D8/04
Filed: 1958-03-03
Abstract: 849,125. Feeding stiffeners to moulding machines. PEMBERTON & CO. Ltd., A. Feb. 27, 1959 [March 3, 1958], No. 6726/58. Class 17(1) A device for feeding heel stiffener blanks into a moulding machine, comprises a carriage 6 carrying clamps C whose jaws 8, 9 engage the blanks. Before the cycle begins vacuum tube 27 rests on the topmost blank of a stack of blanks in a magazine 4 (Fig. 2), and carriage 6 is in its rearmost position nearest the magazine; transverse body 7, mounted rotatably about its axis on the carriage and carrying the clamps, is in such a position that the clamps face towards the magazine; the clamps C which can rotate about spindles in a bearing 13a, are both in a vertical position (Fig. 5), their jaws 8, 9 engaged about a blank inserted in positioning elements 11, 11a at the end of the previous cycle. At the beginning of the cycle, vacuum is applied at the top end of the tube 27, solenoids are energised to close the clamp jaws to grip the blank, and the carriage 6 is moved forward. (A fluid pressure operated piston-and-cylinder preferably effects the movement of carriage 6, though electrical or mechanical means may be used). Vacuum tube 27, attached to the carriage .by chain 34, is pulled upwards through sleeve 28 as the carriage moves forward, bringing with it blank B. A friction disc 19 mounted on the body 7 engages a fixed bar 20 and causes body 7. to rotate as the carriage moves, so that when the carriage reaches its forward position, the body 7 has rotated through 180 degrees and the clamps' are facing the moulding machine. The clamps C are connected by gearing to the shaft 26 of body 7 so that as the body rotates through 180 degrees, the clamps rotate through 90 degrees in opposite directions, so as to bend the blank B into a U-shape (Fig. 6). At the final stage of the carriage advance, pressure plate 17 pushes the blank into the moulding machine and the clamps C are opened. When the vacuum tube reaches its uppermost position, it is swung inwards about pivot pin 15 (see Fig. 7 (not shown)), and against spring 29 by chain 34, thus placing the next blank between positioning elements 11, 11a. Finally the carriage 6 is returned to its initial position, the tube 22 drops down to engage the stack of blanks and the clamps C engage about the newly positioned blank. At each end of its travel the transverse body 7 is prevented from rotating freely by a member 21 having parallel locating flats 21a adapted for engagement with straight portions 22a of fixed bar 22.

March 4, 1931, No. 6736. Convention date, March 5, 1930. [Class 40 (v).] Condensers of known type, having a dielectric of gas under artificially increased or reduced pressure, are used for coupling highfrequency signalling or control apparatus to a transmission line, or for bridging-over transformers or like points of high impedance. Such condensers have small dielectric losses, and are smaller and therefore lighter and more convenient in use than those of the solid-dielectric type. They also permit the use of shorter wavelengths than those hitherto employed.

Abstract: 120,850. Doyle, T. E. April 23, 1918. Peat, preparing.-To facilitate handling and drying of peat after it has been cut in the bog, the peat is reinforced by piles or lengths of timber, iron, reinforced concrete, &c., which are driven into the bog in advance of the peat-cutting machines, for which the piles also serve as foundations. Columns or blocks of peat are cut out about one or more of the piles, which are then lifted from the bog, together with the columns or blocks adhering to them. Reinforced by the piles, these columns or blocks can be placed upright and dry more rapidlv than they would do if they were laid on their sides.

Abstract: 1419825 Insulated tubes; tube supports B CHADWICK 13 Feb 1973 [16 Oct 1972] 7023/73 Heading F2P [Also in Division F4J] A chimney or conduit section comprises an outer casing 13, an inner casing 14 supported therefrom, insulating material 33 supported therebetween and means permitting radial and longitudinal expansion and contraction of said inner casing independently of said outer casing. Each end of the casing 13 carries a flange 15 which extends inwardly between flanges 17 attached to the inner casing with the interposition of gaskets 18 and packing 19, adjacent flanges being bolted together at peripheral points 16 to form the section joints. Flanges 23 on outer casing 13 enclose the insulation 33 and carry pairs of brackets 27 engaging lugs 25 extending radially of the inner casing 14 and secured to the flanges 17. The inner walls of each pair of brackets form obtuse angles defining apices (28, Fig. 3) which have a slight clearance with the lugs 25. The base of each pair of brackets is radiused as at 30, Fig. 2, giving point contact with the edges of a lug 25. The mounting so described enables relative movement between inner and outer casings. Corresponding longitudinal movement is enabled by a sliding joint assembly 35 comprising inner casing portions 14A, 14B, sleeves 36 and 39 with a spacer band 38 welded to portion 14A and enclosing said portion 14B plus a spacer band 40 and packing 41.

[Also in Division G1] A timer for photographic printing exposure times comprises a capacitor charged by a photodiode illuminated by a pilot lamp and a switching unit operated at a predetermined capacitor potential to terminate exposure. A capacitor appropriate to the emulsion sensitivity is selected from capacitors 21 by switches 21a ... 21d. Exposure is initiated by a pushbutton 11 which closes contact 2 to open the shutter and opens contact 5 to allow photo-diode 20 to charge the selected capacitor. The charging current is determined by the brightness of lamp 23 connected to the same supply as the printing lamp which is governed by resistors 25 which are selected in accordance with the gamma to which the emulsion is to be subjected on development and a calibrating resistor 26. This brightness is further modified by a diaphragm 24 adjusted in accordance with the density of the original. The switching unit 12 is of a type in which current between electrodes 13 and 15 is interrupted when the potential on an electrode 14 relative to electrode 13 rises above a threshold value. The potential on electrode 13 is determined by a resistor 17 selected in accordance with filter factors and a resistor set in accordance with the degree of enlargement employed. When conduction between electrodes 13 and 15 is interrupted, relay 10 drops out, opening contact 2 to close the shutter. In a similar ancilliary apparatus for determining development times resistor 18 and shutter 24 are omitted and a fixed capacitor is used in place of capacitors 21. The resistors 25 are selected in accordance with the type of emulsion in use and resistors 17 in accordance with the development gamma. The ancilliary apparatus may be included in the same unit as the timer of the invention, components being used in common.

Abstract: 545,075. Bearings. BUSKE, A. March 7, 1939, No. 7428. Convention date, March 7, 1938. [Class 12 (i)] A bearing bush B is made of material having a higher co-efficient of heat expansion than the material of the bearing housing, and the latter is strengthened at one point at least by a rib G, the wall thickness of the housing on both sides of the rib being diminished to such an extent that the deformation forces between the bush and the housing in consequence of the heating up of the bearing in use remain below that which would produce plastic deformation of the bush. This construction also permits of expansion of the bush at the ports remote of the rib or ribs G so that the bush has a shape such as shown in Fig. 2, to agree with that of the shaft when distorted or flexed under load. Further the tendency of the bush to become loose is reduced. If desired the outside diameter of the bush in the vicinity of the ribs may be less than the corresponding bore of the housing.
