Title: Improvements in connection with type setting machines
IPC: B41B3/00
Filed: 1921-05-24
Abstract: 184,900. Pusino, O. May 24, 1921. Setting type; keyboards.-Relates to machines for setting type having slotted shanks so that they may slide upon rules. The type, which have slots 1, Fig. 1, preferably inclined or bevelled at the upper end, are stored on rules 3, Fig. 2, on which they are retained by lugs 4 and pins 5. The lowest type on a rule can be raised by means of a sliding block 6 having a forked extension 6<1>, and then slides down the lower portion of the rule into a rectangular twisted tube 8 by which it is rotated and permitted to fall upon a collect. ing-rule 9 having an arresting-stop 10. The blocks 6 are raised by levers 7 and rods 7<1>, oper. ated by keys 7<11>. When a line has been composed, the stop 10 is removed, and the type are pushed on to a removable rule 11, which exactly fits the slots in the type.

Title: Improvements in or relating to the purification of pyrethrum extract
IPC: A61K36/28
Filed: 1958-05-06
Abstract: A crude pyrethrum extract, especially one containing 20 to 30% by weight of materials extracted from pyrethum flowers, is purified by mixing the extract with a hydrocarbon solvent boiling within the range 125-350 DEG  C., treating the mixture with trisodium phosphate dodecahydrate, heating it at 40 DEG  to 70 DEG  C. for 1 to 24 hours, chilling the mixture at -10 DEG  C. to -30 DEG  C. for 1 to 24 hours and separating the sludge so formed.  It is preferred to dilute the crude with kerosene to a pyrethrin concentration of 10 to 15% and add 0.01 to 1% of trisodium phosphate dodecahydrate. The clarified extract may be treated with charcoal to remove colour and the so formed clear pyrethrin solution is used as such, or after further dilution with kerosene, as an insecticide.

Abstract: 817,165. Magnetic recording and reproducing apparatus. INDUSTRIAL DEVELOPMENT CO. ESTABLISHMENT. May 8, 1957 [May 8, 1956], No. 14641/57. Class 40 (2). A magnetic record apparatus includes a translator 26 comprising an eraze head 55 and a sound head 54 wherein the eraze head has at least two successive air gaps 60, 61 spaced in the direction of movement of the record medium 30 whereby said medium moves past three or more magnetic poles of alternate polarities. The eraze head comprises a three-limbed core 59 which is rendered effective as an eraze head by the movement of a bar magnet 63 to the position shown in Fig. 6 from the inoperative position shown chain dotted under the control of a knob 27.

Abstract: 309,331. Olsson, J. G., and Stenfors, F. I. E. May 18, 1928. Heating-fittings; air, controlling direction of flow of; wheeled tracks, moving; helical bladeconveyers.-In apparatus of the kind in which material is dried either by bringing the material into direct contact with heating surfaces, or by the transmission of heat by a drying medium, e.g. air or steam, from heating surfaces to such material, and wherein the evaporated water is condensed on cooling surfaces, heat is recovered by utilizing the same medium for heating the heating surfaces and cooling the cooling surfaces. The medium after being heated is caused to pass through ducts from warmer to successively colder parts of the drying room, and having reached the coldest part it is further cooled and then is passed through pipes from cooler to warmer parts of the drying room and from thence to the heater. Figs. 1 and 2 show a drying room 1, through which material mounted on trucks is passed, provided with heating tubes 2 and cooling tubes 3 through which medium is circulated past a heater 5 and refrigerator 10. Air is circulated by fans 4 to pass over the heater 2 and deposit moisture on the cooling tubes 3. The direction of air circulation and flow of the heating medium may be reversed and in a modification one of the series of tubes may be mounted below the trucks. In the form shown in Figs. 6 and 8 the direction of flow of the air is varied by shutters 11 and fans 12. Fig. 10 shows a cylindrical drying chamber through which granular material is fed by helical blades 17. The walls are hollow to form ducts 2, 3 for the heating and cooling medium which is circulated by a fan past a heater at the feed end of the apparatus.

Patent GB-150721-A (GB)
Abstract: 150,721. Lane Bros. Co., (Assignees of Lane, G.). Jan. 15, 1916, [Convention date]. Jacks.-In ratchet jacks, the means for reversing the action of the jack is controlled either by moving the handle in its socket or by moving a separate part carried at the side of the handle. The pawls 5, 4, Fig. 4, are connected by helical springs 13, 14 to bell-crank levers which are mounted on the casing and are acted on by a spring C. When a cross bar 21 is in the position shown, the movement of the bell-crank levers is obstructed alternately, and the lifting-pillar is lowered. If the bar 21 is moved to a position in which it does not interfere with the movement of the bell-crank levers, the lifting-pillar is raised. The bar 21 is carried by an arm 21a pivoted in the socket 6 for the handle and is normally kept in the position shown by a spring. The inner end of the handle 7 has a projection 18a which bears against the bar 21 and keeps it out of the path of the bell-crank levers when the handle is inserted as far as possible into the socket. When the handle is partially inserted, the bar 21 remains in the position shown in Fig. 4. The handle is retained in either position by the engagement of a dog 19 mounted on a spring secured to the socket with one of the notches 18b, 19<b>. The handle is made in two parts hinged together to facilitate storage. In a modification, the bar 21 is moved by a longitudinally movable rod mounted in guides on the handle. In another modification, the inner end of the handle is formed as a cam which moves the bar 21 when the handle is rotated.

Title: Improvements in impulse phase measuring systems
IPC: H04L25/04
Filed: 1942-10-30
Abstract: 558,933. Phase-difference measurements. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 30, 1942, No. 15292. Convention date, Oct. 31, 1941. [Class 37] An impulse phase measuring system employs negative transconductance valves for measuring the phase of an impulse voltage in relation to a reference voltage of the same frequency. A pair of pentodes T1, T2 have their suppressor grids 7, 17 connected in parallel, the anodes 9, 19 being also connected in parallel. The screen grids 5, 15 are connected through a pair of serially connected resistors 21, 23 across which is connected a voltmeter 25. The junction 27 of the resistors 21, 23 is connected to the cathodes 1, 11 through a battery 29 so that the cathode to screen grid circuits are connected in push-pull, the screen grids 5, 15 being positively biased with respect to the cathodes 1, 11. The battery 29 is also connected to the anodes 9, 19 through a resistor 31 and a condenser 33 may be connected between the anodes and cathodes. The reference voltage E1 is applied to the grids 3, 13 through a transformer 35 and resistors 41, 43, a battery 37 being connected to a central tapping on the secondary winding to maintain the grids 3, 13 negative with respect to their cathodes. The reference voltage E1 is thus applied to the grids 3, 13 in push-pull. The impulse voltage E is applied to the suppressor grids 7, 17 by an input circuit 45, a battery 47 applying a negative bias to the suppressor grids 7, 17 through a resistor 49. The voltmeter 25 indicates directly the phase relation between the impulse voltage E and the reference voltage E1. The reference voltage E1 may be sinusoidal or may have flattened peaks, in which latter case the resistors 41, 43 may be omitted.

Title: Method and apparatus for electrical perforation of webs
IPC: B26F1/28
Filed: 1978-04-18
Abstract: For electrically perforating a web (10) of paper with a high perforation density, the web of paper is moved at a constant speed between two groups of electrodes (RL; FR). Two of the electrodes (RL-1, RL-10; FR-1, FR-10) of the groups in each case are situated with their points opposite one another. While the web of paper is passing between the points of the electrodes, an alternating current is applied to the opposite electrodes and two streams of gas are fed to the points of the electrodes through outlet apertures (34). Appropriate selection of the current amplitude and the flow rate of the stream of gas causes multiple piercing for each half-wave of the alternating current applied. In this way, more than one perforation is produced in the web of paper for each half-wave. <IMAGE>
