IPC: D06H3/16
Filed: 1949-09-08
Abstract: 676,235. Inspecting fabrics. B. P. HALL (TEXTILES), Ltd., and HALL, W. H. Aug. 23, 1950 [Sept. 8, 1949; March 10, 1950], Nos. 23234/49 and 6023/50. Class 42 (ii). A form for examining hose comprises a taper cage formed from rods attached to a rotatably mounted base-plate and having a centrally disposed longitudinal member carrying a pivoted arm which can be angularly adjusted about its pivot to engage the end of the arm in the heel pocket of hose placed over the cage, and extend the hose. The cage comprises elongated U-shaped members A, B, attached to a base-plate C which is rotatably mounted on a bracket D. The members A and B are secured together at their distal ends. An arm F, pivoted at E<SP>2</SP> in a slot in a central tube E is connected by a link F<SP>1</SP> to a member G slidable in the tube E and connected to a rod H which passes down the tube and is connected by a flexible cable J to a pedal- or knee-operated lever. Interchangeable arms F may be provided for expanding the heel pocket of different sizes of stocking. For distending the leg portion, longitudinal rods K, K<SP>1</SP> may be provided, supported on the tube E by pivoted links L, and connected by links N to a slide M secured to the rod H. The links N may be connected by links 0 to a member P, loosely mounted on the rod H and pressed away from the slide M by a spring Q. An adjustable stop R, secured by a locking screw S, arrests the member P when the rod H is moved by the cable J, causing the rods K, K<SP>1</SP> to move laterally. Shields of metal, plastic or other suitable material may be secured to the members A, B, K and K<SP>1</SP> to act as a solid backing to the fabric.

Abstract: 990,766. Latch fastenings. MASSEYFERGUSON Ltd. June 11, 1963 [June 13, 1962], No. 23303/63. Heading E2A. A hingeable door 1 has a door latch mechanism including a handle 21 pivoted to the door and accessible from its front face, a pivotal latch 11 on the door jamb 13 having a hookshaped end projecting beyond the jamb, a first latch aperture 8 at the rear of the door, a vertically slidable latch bar 6 on the rear face of the door which is in alignment with the jamb when the door is in the closed and latched position, a second latch aperture 7 in the latch bar, normally in alignment with the first latch aperture so that in the latched position of the door the hook-shaped end is retained in the first aperture and projects into the second aperture, the handle having linkage means 22 connected thereto and operatively connected to the latch bar whereby when the door is in latched position and the handle is pivoted, the latch bar is raised and the lower confines of the second latch aperture moves the latch to permit the latch to move out of the first aperture and allow the door to be opened. As shown there are two of said latches 11 each of which has a hooked free end and each being pivotally mounted so that the hooked end projects through an aperture 12 in the jamb and when the door is closed through a said aperture 8 in the door. The handle 21 is U- shaped and both legs project through the door, one forming a pivot pin for the handle and the other passing through an elongated slot. On the inside of the door the linkage means 22 is attached to the handle legs and one end engages the latch bar 6 via rubber buffer 27 and a bracket 28. The latch bar 6 engages the two latches by means of the lower edges of the apertures in the bar, to lift the latches to their door releasing position when the handle is turned. The other end of the means 22 is bent at right angles and projects through an arcuate slot in the door into a U-shaped bracket 19. Both legs of the bracket and the end of the actuating member 22 are provided with apertures through which the hasp of a padlock can be passed to lock the door closed. The handle is arranged to project slightly from the front face of the door to act as a buffer.

Title: Improvements in or relating to hat brim curling machines
IPC: A42C1/06
Filed: 1922-08-28
Abstract: 186,049. Miller, S. J. Sept. 13, 1921, [Convention date]. Curling.-A hat-brim curling- machine comprises a curling- shackle, a curling-tool adapted to co-operate therewith, a guide for the brim, and an adjustable gauze co-operating therewith self-adjusting for varying thicknesses of the material of the brim. As shown, the brim 13, Fig. 3, of the hat 12 is curled between a curling-shackle 15 heated by a burner 17 and a rotating curling- tool 19. The tool is pressed upwardly and rearwardly by springs towards the shackle 15. The brim is fed by driven rollers, the outer roller 45, Fig. 2, being mounted on a slide and pressed against the brim by a spring 57; the bearings of the rollers are shielded from moisture squeezed out of the hat. When a hat bodv is to be placed in the machine, the roll 45 is moved to the left by a lever 60 engaging the slide and connected by a link 62 to the treadle. The same link operates a lever 94 moving a roll 79, which normally presses the brim towards the tools, to the left. When a hat is placed in the machine the brim is engaged with a vertical wall 16 which afterwards merges into the shackle 15, the upturned portion of the brim being gauged by a member 73 projecting through a gap in the wall 16. adjusted vertically by a screw 74 and self-adjusting horizontally for various thicknesses of material. The plate 83, Fig. 3, on which the hat rests during normal treatment, may be removed if the curl is to be produced on the underside of the brim. The removal of the plate allows the hat to be treated in the inverted position.

Abstract: 1,124,680. Data transmission systems. AUTOMATIC ELECTRIC LABORATORIES, Inc. 25 May, 1966 [2 June, 1965], No. 23453/66. Heading H4P. Binary data is transmitted by a frequency shift system in which the two frequencies have a frequency difference equal to the data bit rate, an integral number of cycles per bit interval, and zero phase at the bit transition points. Various forms of transmitter are described, Figs. 2, 4, and 6 (none shown), each of which produces a single side-band signal in which the 1 and 0 bits are respectively represented by f 1  and f 2  and in which frequencies f 1  and f 2  are present continuously but are phase displaced from the 1 and 0 frequencies. The continuous frequencies are separated at the receiver from the 1 and 0 frequencies and applied to a product modulator which develops the difference frequency. This is at bit frequency and controls a bit-rate clock which samples the data signal for regeneration of the original data.

Title: Process for the manufacture of very pure silicon
IPC: C23C16/22
Filed: 1956-07-30
Abstract: Pure crystalline silicon is produced by the thermal decomposition of vaporous mono-, di-, or tri-halogen substituted silane, the substituted silane being passed through a heated tube in which it is subjected successively to a rising temperature, a maximum temperature of 800-1150 DEG  C., and then a decreasing temperature.  The reaction may be carried out at above or below atmospheric pressure.  A pressure of 1300-1500 mm. of mercury is specified.  Dichlorosilane is preferably decomposed at a temperature of 800-1000 DEG  C., trichlorosilane at 850-1150 DEG  C. and tribromosilane at 850-1030 DEG  C.  Mixtures of these silanes may be used.  The substituted silane may be admixed with an inert gas, e.g. argon, nitrogen, or hydrogen.  The heated tube may be of quartz and may be heated by a high-frequency induction coil.  The silicon may be deposited on a shaped body, e.g. a rod or tube of silicon, silicon dioxide, or silicon, molybdenum, or tungsten carbide contained in a heated tube. A shaped body in the form of a rod may be moved through the tube during the decomposition to form a rod-like extension of precipitated silicon.  The silicon produced may be washed with aqueous hydrofluoric acid followed by caustic alkali.ALSO:Pure crystalline silicon is produced by the thermal decomposition of vaporous mono-, di-, or tri-halogen substituted silane, the substituted silane being passed through a heated tube in which it is subjected successively to a rising temperature, a maximum temperature of 800 DEG -1150 DEG C., and then a decreasing temperature.
