Title: Improvements in knitted fabrics including stockings and half-hose, and methods of making the same
IPC: D04B1/26
Filed: 1931-10-20
Abstract: 383,026. Stockings. HEMPHILL CO., Central Falls, Rhode Island, U.S.A.-(Assignees of Lawson, R. H. ; Pawtucket, and Lovell, R. F. ; Providence, both in Rhode Island, U.S.A.) Oct. 20, 1931, No. 29097. Convention date, Oct. 20, 1930. [Class 141.] A stocking, half-hose, or other knitted fabric has incorporated in it an elastic thread 5 which is knitted in at one or more wales 7, 8 in one or more courses, but is otherwise floated. The elastic thread in a stocking is preferably located in a portion 4 of the top, which is partially separated from the remainder of the stocking to form a garter section. The separation may be effected by partly unravelling a suitably knitted course or by cutting the wales, and sewing stitches may subsequently be applied to the stocking top to prevent running of the disconnected wales. In knitting a rib fabric or rib top for a stocking, the floated portion of the elastic thread mav be held between the frame and rib loops, while in the formation of a plain, i.e. unribbed, fabric, the floated elastic thread may be made to pass alternately in front of and behind the loops of the ground fabric. To do this, alternate needles which do not knit the elastic thread are lowered so that the elastic thread is fed over the top of them, and the remainder of these needles are raised so that the elastic thread is laid against their shanks. Adhesive may be used to assist in holding the elastic thread more or less fixed with respect to its original position in the fabric.

Title: Manufacture of benzene hexachloride
IPC: C07C17/02
Filed: 1937-10-26
Abstract: 504,569. Chemical apparatus. GRANT, A. E., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Oct. 26, 1937, No. 29273. [Class 1 (i)] [Also in Group IV] Benzene hexachloride is manufactured by passing cold benzene, e.g. as a film or spray at about 20‹ C. and not above 60‹ C. countercurrent to chlorine while exposing the reactants to actinic radiation, delivering the resulting liquid to a delay or capacity vessel wherein the reaction between the benzene and dissolved chlorine is completed, and thence to a boiler from which unchanged benzene is vaporized and returned after condensation to the reaction zone. Benzene hexachloride can thus only separate in the boiler and cannot block the apparatus. Any substituted benzenes formed or retained in the boiler and heptachlorbenzene or higher chlorinated bodies cannot be formed. Cooling devices may be employed if necessary. The capacity vessel and reaction zone are both illuminated by actinic light. Benzene may run down the inner surface of the reaction tube up which chlorine is passing or may be sprayed into the top of the tube or may descend as a column of liquid into which the chlorine is bubbled. The capacity vessel may be merely a large receiver into the lower part of which liquid is delivered from the reaction zone and from the upper part of which it may be drawn off and delivered to the boiler or a coiled glass tube may be used. The reaction tube may be packed with transparent material to ensure the exposure of a large area of benzene to the chlorine: The process may be worked by continuously or intermittently introducing benzene to the top of the reaction tube, and continuously or intermittently withdrawing liquid from the boiler, removing solid hexachloride therefrom and either returning the mother liquor to the boiler or separately distilling the benzene therefrom and returning it to the reaction tube. In a modification benzene is passed through a U-shaped, apparatus and chlorine introduced into the lower part of the limb down which the benzene is flowing. This limb then corresponds to the reaction zone and the other to the delay vessel, both limbs being illuminated. Metals such as iron or copper which catalyse substitution reactions should not be employed. Specifications 483,823, [Group IV], and 486,298 are referred to.

Title: Improvements in or relating to automatic gain regulators for carrier current telecommunication systems
Inventor: HELLIWELL BRIAN STANLEY
IPC: H04B3/08
Filed: 1957-09-17
Abstract: 853,771. Telephone transmission systems. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. Sept. 4, 1958 [Sept. 17. 1957], No. 29316/57. Class 40 (4). In a transmission system in which repeaters are fed by a constant current from one of the terminal stations, this current is used to assist in controlling the gain of the repeater. Thus in one embodiment the current is passed through a fixed resistance to provide a reference voltage, against which the voltage derived from a pilot current is compared, the result of the comparison determining the gain of the repeater. In a second embodiment the feed current passes through the parallel connection of a thermistor T2, whose resistance is varied according to the ground temperature, and the heating winding HW of a second thermistor T 1  lying in the negative feed-back circuit of the amplifier A. Thus the current in the heating winding is varied according to the ground temperature to vary the gain of the amplifier.

Title: Improvements in drilling machines
IPC: B23B39/00
Filed: 1921-11-11
Abstract: 192,208. Riley, A., and Holroyd & Co., Ltd., J. Nov. 11, 1921. Drilling-machines.-Relates to power-feed drilling machines and consists in providing a resiliently yielding transmission for the feed motion so that the spindle feed is arrested automatically when the drill encounters abnormal resistance. The feed mechanism may be thrown entirely out of gear and means are provided whereby the feed motion may be set to drill holes of predetermined depth. The drill-spindle 1, Fig. 1, is fed by a rack 4 and pinion 5, Fig. 4, the pinion being integral with a spindle 11 on which is loosely mounted a worm wheel 12, positively driven through worm gearing from the shaft 2, Fig. 1. A disc 7, Fig. 4, is also loosely mounted on the spindle 11, but may be clamped against the pinion so as to revolve therewith by means of an end-nut 9. The disc is provided with a stud 18, Figs. 1 and 3, on which is pivoted a member 17, working in a slot in the disc and carrying a spring-pressed ball 21 which is adapted to engage with adjustable pressure one of a series of holes 25 in the worm wheel 12. The worm wheel accordingly only transmits feed while the drill resistance is insufficient to force the ball out of engagement with the hole. For permanently disconnecting the transmission, the member 17 is oscillated so that the ball 25 engages a concentric V-groove 26 in the worm wheel. Holes of predetermined depth are drilled by setting the stop 27, and clamping the disc 7 in such an angular position that at the required instant the stop 27 engages a nose on the member 17 and transfers the ball from a hole. to the V-groove. Small projections may be used in place of the holes 25. Change gears and worms with multiple thready may be used in the transmission. The drillspindle head is vertically adjustable on the machine column and a balance weight is employed to restore the drill to the initial position.
