Title: A process for coating balls, in particular tennis balls, with seamless felt, and a device for carrying out the process
IPC: B29D22/04
Filed: 1957-11-01
Abstract: 834,102. Felting. SEIDEL, W. Nov. 1, 1957 [Nov. 7, 1956], No. 34155/57. Class 42 (2). [Also in Group XV] A device for applying a seamless coating of felt to cores of tennis balls, comprises a rotary drum 1 having openings 12 in its end faces, and a semi - cylindrical member 13 resiliently mounted inside the drum. Round cores 17, which have previously received an undercoating of fibres, are fed into the drum, together with feltable fibres which are blown into the drum through the openings 12. As the drum 1 rotates in the direction indicated by the arrow B, the cores 17 are continuously forced through the gap between the curved surfaces of the drum and member 13, in the presence of a fulling liquid, with the result that fibres adhering to the cores during their passage down the inclined surface 16 of the member 13 will be subjected to pressure and fulled. When the coating is sufficiently thick, the fulling liquid is replaced by fresh water for washing the balls, and eventually the latter are dried by blowing hot air into the drum 1.

Title: Process for the preparation of a liquid hydrocarbon mixture suitable as motor gasoline or as a blending component therefor
IPC: C10L1/06
Filed: 1962-09-06
Abstract: Gasoline or a blending component therefor is obtained by contacting a light olefin-containing hydrocarbon feed boiling in the range - 7 DEG to 230 DEG  C. with a hydroisomerization catalyst comprising a hydrogenation component on an acidic support in the presence of hydrogen without substantial cracking, separating at least part of the product into a naphtha fraction and a lower boiling fraction and catalytically reforming at least part of the naphtha fraction in the presence of hydrogen. The initial feed may be a thermally or catalytically cracked material, preferably containing C4-C6 olefins. The hydroisomerization catalyst is preferably a sulphide of a Group 6A metal or iron group metal or a mixed oxide or aluminahalogen support, preferably silica-alumina, and conversion, yielding isoparaffins and naphthenes, is effected at 200-485 DEG  C., 10-100 atms. with 1-20 mols. of hydrogen per mol. of feed at an LHSV of 0.5-20. Excessive temperature rise may be prevented by a plurality of catalyst beds with intermediate cooling or recycling liquid product or, preferably, by adding a straight run naphtha boiling in the range 90-200 DEG  C. which is a suitable feedstock for the subsequent reforming to which it is also subjected with the hydroisomerization product. The effluent is separated into light product and naphtha with a cut point of 75-110 DEG  C. preferably about 85 DEG  C. and the naphtha conventionally reformed, the excess hydrogen produced being used in the prior hydroisomerization. The reformate may be blended with the light hydroisomerizate fraction in a volume ratio of 1 : 1-15.

In the arrangement illustrated, the invention is applied to supplying plate current. and grid bias to thermionic valves in a wireless receiver. The supply transformer T has three secondaries S1, S2, S3 supplying three fullwave rectifier groups K the elements of which may be copper-oxide devices as described in Specification 257,305, [Class 37, Electricity, Measuring &c.]. These groups are connected m series as regards the output connections so that between terminals 5, 13 a voltage suitable for the plate circuit of the valve A2 is available, whilst between terminals 5, 3 a lower voltage suitable for the plate circuit of the valve A1 is available. A third voltage for the plate circuit of the detector valve E is obtained at the terminals 4, 5 by using a resistance 9. Grid bias of various values is then obtained at terminals 17, 18 by using a potentiometer 19. Smoothing devices comprising inductances L1, L2, L3 and condensers C1, C2, 03, D1, D2, D3 are inserted in the various circuits. The Specification as open to inspection under Sect. 91 (3) (a) describes also an arrangement in which a plurality of secondary windings on the transformer are connected across various portions of two oppositely connected groups of rectifier elements, the various voltages required being obtained between the junction of the two groups and the mid-points of the various secondaries.

Abstract: 331,470. Pearson, F. A. Nov. 22, 1928, [Convention date]. Controlling variable-speed gearing.-In variablespeed gearing, the gear is changed by the power of the engine so that driving-shaft a moves orbitally between the position shown with a pair d, e engaged to a position in which pair d<1>, g is engaged, countershafts e<1>, g<1> and driven shaft # not changing position. The shaft a which is universally jointed at b passes eccentrically through a bush i which can turn in a fixed support h. The bush i is secured at i<1> to a frame p carrying planet gears n, which mesh with a loose internal gear k, and with a sun pinion m fast on shaft a. In the position shown, frame p is held by a trip q so that bush i is fast, gear k running loose. To change speed, trip q is caused by means such as an electromagnet r to engage and hold gear k. The planets n roll, turning the bush i through the half revolution necessary to make the speed change. In a modification, the orbitally-moved driving-shaft carries a worm between two driven worm-wheels geared together, the change of mesh effecting reversal of drive.
