Title: Process for producing tubular boules
IPC: C30B29/26
Filed: 1970-02-10
Abstract: 1279382 Growing tubular crystals SHINKOSHA KK 10 Feb 1970 [27 Feb 1969 15 Oct 1969] 6341/70 Heading B1S [Also in Division C1] A tubular boule is produced by a Verneuil process using a double-tube or triple tube apparatus in which the nozzle supplying the material to be crystallised has within it an obstruction for preventing any of the material from reaching the centre of the top of the boule and thus producing a tubular shape. The embodimnt illustrated has either a circular rod 10 in the tube 3 so that the material and flame comes out in an annular ring (Fig. 3) or a rod of substantially rectangular crosssection in an oval tube shape (Fig. 4) so that the flame and material come out as two separate streams from the nozzle. The boule is rotated and lowered in both cases. A further embodiment (Fig. 2b) with three tubes is described, the nozzle obstruction here being a tube through which passes one of the gases for supplying the flame (e.g. oxygen or hydrogen). A crystal seed can be used to grow the boule on if a special crystalline structure orientation is required. Examples are given of growing boules of MgO.3Al 2 O 3  and sapphire.

Title: Improvements in or relating to electric selective signalling systems
IPC: H03F1/54
Filed: 1940-04-09
Abstract: 538,246. Impedance networks. ERICSSON TELEPHONES, Ltd., and CROWE, D. C. April 9, 1940, No. 6389. [Class 40 (iii)] [Also in Groups XXXVIII, XXXVII and XXXIX] In a supervisory arrangement for a broadcast distribution system (see Groups XXXVIII and XXXIX), the volume of a programme supplied to the feeders is controlled from a distant point by means of a chain of relays QA, RA, SA, TA (not shown), having two normal positions which they take up alternately in response to successive energizations. To increase the volume impulses are sent in pairs to build up the chain from one condition to the next, and to reduce the volume impulses are sent singly to break down the chain in the reverse order. The amplifier circuit includes an attenuation pad of series and shunt resistances which is adjustable under the control of relays QA, RA, SA, TA. To adjust the volume, the operator dials 2, which results in the change-over of relays QA, RA. The line is now connected to allow the operator to listen to the programme. He then repeats the dialling operation as many times as is necessary to bring the volume up to a suitable level, the maximum volume being obtained after seven steps. Relay QA changes over at each step, RA at the first step as stated above and again at steps 3, 5, 7, SA at steps 2, 6 and TA at step 4. The operator reduces the volume by dialling single impulses, each of which reverses the effect of a pair of setting impulses, until finally ZA changes over and cuts off the power supply.

Title: Improvements in metal working presses
Inventor: JOHANSEN EINAR KELL
IPC: F15B21/00
Filed: 1954-03-08
Abstract: 750,046. Metal-working presses. U.S. INDUSTRIES, Inc. March 8, 1954, No: 6658/54. Class 83 (4). A mechanical metal working press having a crown and bed connected by tie-rods and a reciprocating slide, has an over-load device comprising a movable member 26, Fig. 4, loaded on one side by hydraulic pressure and on the other side by air pressure and means 30, 31 acting on the hydraulic fluid in response to an overload on the press for moving the member 26 against the air pressure and thus relieving the overload. Each tie rod 10 of the press has screwed to its bottom end a member 31 carrying a cylinder 30 slidable over a piston 34 abutting against the press bed 1. The annular space 35 in the cylinder is connected through ducts 36, 37 and a flexible pipe 38 with a hydraulic cylinder 25 containing a plunger 28 carrying an air piston 26 operating in an air cylinder 24. Hydraulic fluid in a reservoir 12, Fig 5, pressurized by air admitted through pipes 16, 17, is supplied through pipe 41 and check valve 40 to the hydraulic cylinder 25 and hence fills the cylinder space 35. The air pressure also acts through a pipe 18, having a regulating valve 20, on the top of air piston 26, causing plunger 28 to pressurize the hydraulic fluid. When an overload occurs on the tie-rods, the cylinder space 35 is reduced and this causes the plunger 28 and piston 26 to be raised against the air pressure. An extension 42 of the plunger extends out of the air cylinder and in the case of an excessive overload trips a limit switch 43, Fig. 6 (not shown) which causes disengagement of the clutch driving the crankshaft or eccentric shaft of the press. Loss of hydraulic fluid in the hydraulic system causes the plunger 28 to be lowered and this permits the extension 42 to actuate further limit switches controlling a valve 15, Fig. 5, which admits pressure air below the piston 26, causing it to be raised and thus permits further liquid to enter the hydraulic system through pipe 41. The cylinder 30 and piston 34 may alternatively be provided at the upper end of each tie-rod. The press may carry dies for drawing sheet-metal.

Abstract: 127,239. Usines Bolide Soc. Anon., (Assignees of Feutz, A., and Blumenstein, E.). May 18, 1918, [Convention date]. Void [Published under Sect. 91 of the Act.] Feeding webs.-Stamping-presses for stamping or cutting out pieces from a strip of material are constructed with an intermittingly advancing and retiring gripping-device forming part of a cage constructed of iron bars, and this device also renders the use of an ejector unnecessary. The main cage comprises four uprights b bolted to slides c which move in guideways, and connected at the top by two long and two short iron bars a. The main frame is reciprocated by a cam e<1> acting on a roller h<7> on a screw-threaded rod h<5> connected to a plate It secured to the frame, which is acted on by a spring h<4> for returning the frame after the cam e<1> has ceased to act. An adjustable stop h<2> for adjusting the extent of feed is fixed to the plate h. The cam e<1> is on a shaft f coupled to the connecting-rod of the press, and the shaft rotates once for each reciprocation of this rod. The shaft f also carries a cam e which raises and lowers an auxiliary frame d mounted to slide vertically on the posts b and acted on by springs which depress sockets on the frame d which embrace the thinner upper parts b<2> of the posts. The springs keep these sockets in contact with collars b<4> on sleeves b<3> which embrace the parts b<2> of the posts b. In the raised position of the frame d, the strip is gripped between plates d<3> on this frame and curved plates g<3> on spring-depressed rods g<2> which can move down relatively to the cage a to an extent controlled by adjustable stops. This gripping-device is arranged to grip the strip while the punch is acting, thereby dispensing with an ejector, and after the punching operation it feeds the strip the required amount, after which the frame d is lowered while the cage a returns.
