Title: Bar loading apparatus
IPC: B23Q7/00
Filed: 1967-12-29
Abstract: 1,205,580. Grinding; bar-stock feeding. SUNDSTRAND CORP. 29 Dec., 1967 [30 Dec., 1966], No. 59233/67. Headings B3B and B3D. A bar loading apparatus for successively separating stock bars from a supply and delivering them to the bar feeder of a machine tool, such as a centreless grinder, automatic screw machine or turret lathe, comprises a rack 20 for supporting a supply of bars and inclined downwardly towards the feeder which consists of a row of spread apart pairs of power-driven rolls 43, 44 and the rolls of each pair being spaced apart laterally and adjustable to receive bars of various diameters, a series of load levers 63 fixedly mounted in spaced relation along a shaft 30 journalled for oscillation about an axis parallel to the bars in the supply, the levers being movable between an up position forming a continuation of the rack and a down position for placing a bar on the rolls of the bar feeder, and a series of stop levers 70 and retaining levers 73 movable alternately between up and down positions by power means 88, 96 for releasing the bars successively from the supply on to the load levers. The rack consists of a number of beams 20 ... 24 joined at their rear end by a member 25 and at their forward ends are mounted by bearings 27 on the shaft 30 about which the rack is adjustable to vary its inclination by fluid-operated cylinders. The load levers 63 are fixed to the shaft 30 which is oscillatable by a fluid-operated cylinder 112 to move the levers between their upper and lower positions. The stop levers 20 are fixed to a shaft 71 oscillatable by a fluid operated cylinder 26 and the retaining levers 73 are fixed to a shaft 74 oscillatable by a cylinder 88. The cylinders 88, 96 are mounted on slides adjustable in the direction of the cylinder axes by handles 91, 99 to vary the upper positions of their respective levers according to the diameter of the bars on the rack. The rolls of the bar feeder are also laterally adjustable according to the diameter of the bars supplied, opposed pairs of  rolls being mounted on slides 47, 48 adjustable by rods 52 from gear-boxes 54 controlled by a common shaft 55 and handle 56.

Title: Holder for oxygen lances
IPC: F16L41/08
Filed: 1970-12-14
Abstract: 1282238 Oxygen lances MESSER GRIESHEIM GmbH 14 Dec 1970 [22 Dec 1969] 59233/70 Heading F4B An oxygen lance-holder 10, particularly for use with vacuum furnaces for refining steel, includes a flexible sealing device adapted to bear against the lance 5 in gas-tight manner and hold the lance in position by means of fluid pressure. The sealing device comprises a flexible sleeve 13 of synthetic rubber which together with part of the holder and flanges 14 defines an annular chamber 12. The fluid pressure is provided by water which enters the chamber 12 through conduit 15 and leaves through conduit 16. The lance is surrounded by a sheath 17 adjacent the sleeve 13 and by a bellows assembly 21. The lance is watercooled. The sealing device disclosed facilitates automatic variation in the position of the lance according to the level of liquid 1 in the furnace. If changes in the liquid level occur, the pressure in the sleeve 12 is lowered thereby permitting the lance to be vertically displaced; the pressure in the sleeve 12 is then raised to hold the lance in its new position.

Title: Process for the preparation of urea and melamine
IPC: C07C239/00
Filed: 1970-12-16
Abstract: 1320950 Melamine; urea STAMICARBON NV 16 Dec 1970 [20 Dec 1969] 59790/70 Heading C2C In a process for the preparation of urea from NH 3  and CO 2  and of melamine from urea and NH 3  at elevated temperatures, the hot gas from the melamine synthesis zone, containing melamine vapour, NH 3  and CO 2 , is cooled by direct contact with an ammonium carbamate-containing aqueous solution of urea obtained directly or indirectly from the urea synthesis whereby a urea solution containing melamine and substantially no ammonium carbamate is obtained and melamine crystals are recovered therefrom, if necessary after further cooling. Preferably at least part of the gases discharged after contact and containing CO 2  and NH 3  from decomposition of the carbamate is recycled to the urea synthesis and at least part of the urea recovered from the solution after separation of melamine is recycled to the melamine synthesis. For optimum heat economy, the urea solution should contain at most sufficient ammonium carbamate to cool and remove melamine from the hot synthesis gas. The discharged CO 2  and NH 3 - containing gas, which may also contain water vapour, are condensed into an ammonium carbamate solution, for use in the urea synthesis, and the heat evolved used to process the urea solution, recovered from the melamine, which is subjected to vacuum-crystallization and melting before recycling to the melamine synthesis. The amount of ammonium carbamate in the urea solution formed in the urea synthesis may be reduced, by expansion or heating to strip CO 2  and NH 3 , before contact with the hot synthesis gas. Melamine is obtained as a suspension and/or solution depending on the amount of urea solution employed. The process is illustrated by reference to drawings (not shown).

Title: Safety device for preventing radiation leakage from microwave producing apparatus
IPC: H05B6/76
Filed: 1970-12-23
Abstract: 1298163 Testing microwave equipment; microwave ovens INDUSTRIE A ZANUSSI SpA 23 Dec 1970 [17 Jan 1970] 61206/70 Headings H5H and H4L In a device for protection against radiation leakage in microwave generating apparatus, as described, for an oven, a radiation-responsive gas tube 16 is located in the area where radiation leakage can occur and is connected in series with a relay coil 19 controlling normally open contacts 26 in the energizing circuit of the microwave generator 4, a resistor 20 and a potentiometer 21. Potentiometer 21 controls a diode 22 in series with a further relay coil 25 operating normally closed contacts 27 in series with the contacts 26. The device is energized via a full wave rectifier 24 when push-button 23 is closed and the small current flowing through the tube 16 is then sufficient to energize relay 19 and close contacts 26. The resistance of the tube 16 remains relatively high so that diode 22 is cut off, relay 25 is not energized and contacts 27 remain closed. Should a radiation leak occur or the oven door be opened, the resistance of the tube 16 is decreased, diode 22 conducts and relay 25 is energized to open contacts 27. Relay 19 is released to open contacts 26 should the tube break. Oven construction.-Access to the cooking chamber 2, Fig. 2, is via an opening 5 each side of which carries a resilient blade 6, the blades being pressed against the oven wall when the door 7 is closed to provide sealing against radiation leakage. The antenna 3 of a microwave generator 4 is arranged to protrude into the chamber 2. The door is provided with a transparent central area 15 and may be locked in the open or shut position by notches 10, 11 respectively on the lever 12.
