Title: Process for the hydrogenation under pressure of distillable carbonaceous materials
IPC: C10G1/08
Filed: 1932-09-24
Abstract: The production of hydrocarbons by the heat treatment of distillable carbonaceous materials with hydrogen under pressure is carried out in the presence of free organic carboxylic acids which when inorganic salts are simultaneously present do not form complex ansolvo acids. Formic, acetic, and oxalic acids are specified.  Carbonaceous materials having a basic or alkaline reaction are neutralized at least in part by the organic acids or by the addition of other acids. The acids may be added by soaking porous materials, e.g. active carbon, silicic acid &c. therewith and adding these materials to the reaction chamber.  Middle oil in the vapour state is mixed with 2 per cent of formic acid and passed with hydrogen at 200 atmospheres and 430 DEG  C. over a catalyst comprising equal parts of tungsten sulphide and molybdenum bromide and a product is obtained, 55 per cent of which boils below 180 DEG  C.

Title: Improvements in or relating to automatic stitch length control mechanism for circular knitting machines
IPC: D04B9/02
Filed: 1954-01-13
Abstract: 764,694. Knitting-machines. WILKES HOSIERY MILLS CO. Jan. 13, 1954 [Jan. 23, 1953], No. 985/54. Class 74 (2). To maintain evenness of loop structure of a stocking knitted on a circular machine and also to enable the loop size to be varied for fashioning purposes, a pivoted plate 84 mounted in the sinker cam ring 36 is engaged by the sinkers and, depending on the tightness of the loops, moves inwardly or outwardly to influence a detector switch 75. The detector switch is in the circuit of an electric motor which when energized raises or lowers the needle cylinder in relation to the knitting cams to effect an alteration in loop length. By adjusting the position of the switch in relation to the plate 84, the loop length is gradually decreased for fashioning the leg of a stocking. The switch 75 comprises a pivoted arm 82 having a finger 83 held in engagement with the plate 84 by a spring 90 and thereby urges the plate into engagement with the rear end of the sinkers. The end of the arm 82 lies between two contacts 91, 92 which through limit switches control the electric motor 70. Any variation in the position of the plate 84 due to the sinkers moving in too far against the loops or not far enough, causes the arm 82 to contact either of the contacts 91, 92, thereby operating the motor. The motor 70 drives a worm gear 71 connected through a screw 72 to the fabric take-up tube 40 so as to raise or lower the needle cylinder 15 supported at the top of the tube 40. For fashioning purposes, the switch 75 and arm 82 are gradually withdrawn from the sinker ring so that one of the contacts is engaged, causing the motor to lower the needle cylinder, whereby smaller loops will be produced whilst the sinkers engaging the loops press the plate 84 outwardly until the switch 75 is broken. Withdrawal of the switch 75 is achieved by mounting it on a plate 76 which is engaged by a wedge 96 operated through a cable from cams 118, 119, 120 on the shaft of the cam drum. These cams are brought into operation by pawl-and-ratchet mechanism 122, 130 operated from the quadrant gear.

Title: Radio controlled clock provided with a ferrite rod antenna
Inventor: ALLGAIER JUERGEN
IPC: G04C9/02
Filed: 1994-08-11
Abstract: A radio clock (11), in particular one designed for use in homes, should be designed so that even under unfavourable radio reception conditions or random conditions according to the position of installation, it will ensure decoding of the received time data. For this purpose it is proposed that the radio receiver be fed from a ferrite rod main aerial (21), the original directional characteristic of which is damped towards an all-round receiving characteristic by inductive coupling of a balancing aerial (22) also having a tuned aerial circuit, but which is not connected to the radio receiver (14). If, on the other hand, (instead of this or additionally) provision is made for switching between main aerials (21) with different space orientation and each having its own tuned aerial circuit (17), the aerial circuits (17) of the (main) aerial (21) temporarily not connected to the radio receiver (14) are short-circuited or opened in order to prevent oscillatory effects. <IMAGE>

IPC: F16K24/00
Filed: 1990-01-05
Abstract: PURPOSE: To keep the fluid in a container, and to allow the gas to be penetrated in each direction by providing a support body having a porous plastic film which is non-penetrant for water but penetrant for gas in an area of a passage opening, and providing a fluid discharge duct in the film. CONSTITUTION: Air flows in the direction of a film 9 from a sealed container through an internal space 12 of a screwed part and a center opening 13 in a base 4 of a support body, and air flows into a chamber 14 at the center opening 13 through an air penetrant film. Air further passes between the film 9 and an upper side of the base 4 and between the film and an operated knob 11, and reaches the chamber 14 through the film 9. Air flows outside from the chamber 14 through a dust 15 as a gas outflow port, and similarly advanced in the horizontal direction through ducts 10 and 16 to be operated as an air outflow opening. When water is stored on the upper side of the film 9, it flows outside the duct 10. In this condition, the duct 10 is operated as a discharge port of the fluid. The fluid is discharged from the duct 12 when the longitudinal axis is perpendicular.
