Abstract: 950,417. Casting concrete pipes. G. M. ANDERSSON, and E. H. T. GRANSTROM. Feb. 12, 1962 [March 22, 1961], No. 5295/62. Heading B5A. Concrete pipes are cast between a vertical outer mould piece 2, and a vibrating core 1, which is attached to a frame 5 which rests upon a vertically movable carriage 6. The carriage rests upon a block 13 attached to an hydraulically or pneumatically operated piston-rod 12 so that it may be raised to the casting position (shown in Fig. 1) in which position it is locked against downward movement by locks 9, 10, one of which is shown. The rod 14, connected to block 13 and slidable through the carriage 6, is connected by frame 15 to four pull-rods 16 which extend upwards through the core. The upper ends of the rods engage a thrust ring 3 (as in Fig. 2 and 3, not shown) so that upon downward movement of rod 12 pressure may be exerted upon the concrete during the casting operation. After the casting the pull rods and thrust ring are disengaged and the frame 15 lowered until the mechanism 21, 22, 23 releases the catch 9 causing the carriage 6 to drop on to the already lowered block 13, whence the core is further withdrawn from the mould by further downward movement of the carriage. In a modification the locking device may be released manually or by remote control and in a further embodiment cylinder rod 12 may be replaced by a rack-and-pinion mechanism.

Title: Improvements in or relating to radio direction finding apparatus
IPC: G01S3/14
Filed: 1937-02-23
Abstract: 490,940. Locating sounds and like vibrations. STANDARD TELEPHONES & CABLES, Ltd., and EARP, C. W. Feb. 23, 1937, No. 5412. [Class 118 (ii)] [Also in Group XL] In a direction-finding system employing two or more collectors, signals from the collectors are modulated with different wave forms and the resultant modulation envelopes combined with the original modulating wave forms are used for operating an indicating device which may comprise either a cathode-ray oscillograph or a dynamometer. The system may be employed for locating the origin of either wireless or sound waves, wireless waves being described. An aerial system AEW, which gives optimum sensitivity for east-west signals picks up a signal of strength proportional to cos # (# being the bearing of the transmitter from the East). This signal (e cos #) is modulated by a wave form f(t) generated by the modulating generator GEW so that the output of the modulating device MEW is Á. e cos # f(t). A second aerial system ANS for North-South signals similarly produces a modulated output Áe sin # f<1>(t) and the two outputs are combined in an amplifier A with the output Ke from a non-directional aerial AND. The resultant output is passed through a detector D to an indicator I, to which the waveforms f(t) and f<1> (t) of generators GEW, GNS are also fed. The indicator I may be a cathode-ray oscillograph in which case the wave forms are applied to the deflector plates whilst the combined modulated output controls the brilliance of the spot, a straight line from the centre of the scale pointing in the direction of the transmitting station being produced on the oscillograph. The wave forms are deliberately distorted to give sharp peaks when the instantaneous modulation amplitude equals zero. If a dynamometer indicator is provided the wave forms are fed to the field coils whilst the combined modulated output is supplied to the moving coil, which takes up a position corresponding to the direction of the incoming signal. Means for adjustment of the apparatus for unbalance and site errors are given in the Specification.

Title: Improvements in or relating to cranes
IPC: B66C23/72
Filed: 1922-02-24
Abstract: 184,127. Babcock & Wilcox, Ltd., and Hollick, F. W. Feb. 24, 1922. Jib cranes.-Comprises a particular construction of safety mechanism for preventing overloading of cranes, which acts to cut off the power from the hoisting and luffing motors at a predetermined turning-moment due to the product of the Joad and the radius at which it is carried. A spring-urged floating member, forming an anchorage for the tail of the hoisting-rope, is moved proportionately to the load to bring a switch or the equivalent proportionately nearer to a second member influenced by the radius of action, power being cut off when the switch or equivalent strikes against the second member. In the illustrated construction the tail of the hoisting-rope 9 is arranged to depress a lever 1, pivoted at 2, against the action of a spring 4. The lever 1 carries the arm 6 of a switch which, when opened, cuts off power from, and applies electric brakes to, the hoisting and luffing motors 5, 14. The depression of the lever 1 brings the arm 6 correspondingly nearer to a travelling nut 10 mounted on a screwed shaft forming part of the transmission gear between the luffing-motor and the jib. Thus, for heavy loads, the nut operates the switch to cut off the power at a lesser outreach than when light loads are carried.

Inventor: WIRTZ LUIS
IPC: B01D17/02
Filed: 1918-04-04
Abstract: 124,895. Wirtz, L. April 4, 1918. Mineral oils, purifying. - Oil is purified and freed from water by means of a travelling gauze or openwork fabric 2 which dips into the oil in a tank 1 and carries it as a film through a substantially horizontal path so that the water can drop off. The film of oil is afterwards removed or atomized by air currents. The separation of the water takes place while the belt of gauze is passing over compartments 4, 5 formed with inclined bottoms for drainage of the separated water. A vibratory motion may be given to the belt to aid the separation. The water remaining on the belt may be evaporated by currents of air passing through the compartments 4, 5, which are provided with partitions to direct the air through a zigzag path across the belt. The oil is removed from the belt by means of an air-blast which is directed on the belt through channels 18 so as to drive the oil into chambers 19. The air-blast employed may be sufficient to atomize the oil, carburetted air for burning in furnaces &c. thus being formed. The passage of air through the belt may be controlled by shutting the apertures in the base of the channels 18 by valves operated by levers 22. The oil from the collecting-chambers 19 passes through gauze diaphragms. In Fig. 6 is shown a number of gauze cylinders 31 and diaphragms 30 arranged in the delivery pipe 29 for the purpose of collecting any oil that may separate from the carburetted air and exposing it as a film to be again taken up by the air. Further quantities of air from an air compressor may be admitted to the delivery pipe to complete the carburation. The removal of the film of oil from the belt may be effected bv suction alone or by a blast on one side of the belt and suction on the other. Several layers of belts separated by distance pieces may be used.
