Title: Improvements in or relating to dressing tools, particularly for dressing abrasive wheels of grinding machines
Inventor: TEATHER HARRY GEORGE
IPC: B24B53/12
Filed: 1950-06-01
Abstract: 684,267. Trueing grinding wheels; diamond tools. PRECISION DIAMOND PRODUCTS, Ltd. June 1, 1951 [June 1, 1950], No. 13718/50. Classes 60 and 124. Abrasive wheels are trued by a tool in which a tip 32. Fig. II, of diamond or other hard material is secured to a mount 31 associated with indexing means which limit the indexing adjustment of the mount to alternate indexing stations. The indexing means includes a ring 50 secured to the mount by a lock nut 53 and provided with a peripheral series of holes 52 all except two of which are normally covered by a housing 16, Fig. III. To index the mount, a key (not shown) is inserted in the hole appearing in an entry notch 24 and the mount is turned to bring this hole opposite an exit notch 25. In travelling from one notch to the other the key rides along an edge 26 which causes an axial displacement of the mount against the pressure of a spring 56. This displacement frees the ring 52 from a pin 60 which is adapted selectively to engage a circular series of depressions corresponding with the holes 52. The pin is also loaded by the spring 56 and serves to locate the ring at each indexing station. The exit notch is shaped to necessitate withdrawal of the key before further movement of the mount can take place. A screw 43 engaging two clamps (not shown) firmly secures the mount in its housing after each indexing adjustment. A stem 12 is adapted to be engaged by a fixture (not shown) so that the tool is inclined to the surface to be trued. Five, seven or nine indexing stations are provided. The diamond is secured in a metal matrix 33.

Title: A pulse generating circuit arrangement
IPC: H03K5/13
Filed: 1963-04-05
Abstract: 1,025,450. Transistor circuits. TELEFONAKTIEBOLAGET L. M. ERICSSON. April 5, 1963 [April 5, 1962], No. 13750/63. Heading H3T. A circuit for re-timing pulses and replacing missing pulses comprises a stage M for converting each input pulse into a constant duration pulse, the output of stage M blocking a free-running oscillator O, tuned to the required pulse repetition frequency. The oscillator output is combined with that of stage M and fed to an oscillatory circuit S from which the required pulses are derived. As described, each input pulse is lengthened by a monostable circuit M comprising transistors Tr1 Tr2, giving waveform I M . The oscillator O uses a transistor Tr3 and is tuned by L3, C3 so as to be self-oscillatory at the required repetition frequency except when the diode bridge Br is made conductive by each pulse I M . The oscillator thus re-starts after each pulse I M , as shown at I 0 . Summing resistors D1, D2 combine waveforms I 0 , I M . The combined waveform is fed to a transistor Tr4 so that the tuned load S is excited by each pulse I M . The resulting waveform I s+0  is clipped by transistor Tr5 giving I A2  which is differentiated by means not shown, thus providing more regular output pulses I u .

Title: Improvements in or relating to the production from oil gas of low cost gas of desired specification
IPC: C10G5/06
Filed: 1955-05-19
Abstract: 810,094. Purifying gases; gaseous mixtures. STARK, V. May 19, 1955, No. 14478/55. Class 55 (2). Oil gas produced from petroleum oils, such as heavy oils, by a cyclic process, has the higher hydrocarbons extracted therefrom, the gas then being of lower calorific value and specific gravity so as to provide " town gas ". Oil gas formed from bunker oil, refinery residue or other petroleum oil is cooled in a scrubber and flows through a tar separator, oil scrubber, CO 2  purifier and an H 2 S purifier. The dry gas is compressed and cooled in a column, a large percentage of the aromatic hydrocarbons being liquefied and withdrawn. The gas is then further compressed up to 300 pounds per square inch and cooled in a second column to lower temperatures, further hydrocarbons being condensed and withdrawn. The gas then passes upwardly through a tower in countercurrent to an absorption liquid such as sulphuric acid, the gas being then expanded in an engine to reduce its pressure, lower its temperature, and produce electric power in a generator. The hydrocarbon condensate is distilled from the absorption liquid, vaporized and expanded and utilized to cool the oil gas in the columns, and finally heated and fractionated. A liquid is cooled at sub-atmospheric temperature by heat exchange with the expanded gas and used in cooling the oil gas in the stripping stages. The Stripped gas is mixed with blast gas, air, or flue gas to provide the required calorific value of resulting gas.

Title: Improvements in and relating to electric motor controllers
IPC: H02P1/04
Filed: 1921-05-25
Abstract: 177,438. Igranic Electric Co., Ltd., (Cutler-Hammer Manufacturing Co.). May 25, 1921. Push - button control systems; p o w e r driven starters; safety arrangements.-Relates to push-button control systems for starting motors for driving printing-presses. Fig. 1 shows the arrangement of switches and control circuits for a set of two motors, a smaller motor which starts first and a larger one which takes over the work after a certain time. The motors, indicated at M, M<1>, Fig. 2, are respectively connected to double-pole electromagnetic switches 1, 2. A set of push-buttons indicated on the left of Fig. 1 provides means for closing and opening the switches 1, 2 in the required order, for " inching " by the small motor alone, for accelerating by the action of a pilot motor M<2> working a cross-head controller 18, 19, and for giving visible and audible signals before starting. The action is normally commenced by depressing an " on " push-button 12. which closes the pilot-motor forward switch 4 and moves the cross-heads downwards from the position shown in Fig. 1. The upper cross-head 19 during its movement successively switches in the small motor and the large motor, cutting out the small one when the large one is switched in. The lower cross-head successively accelerates the two motors by travelling over two sets of rheostat contacts r, r<1>. If the " on " button is released, and an " off " button 14 is depressed, the pilot motor is reversed through an electromagnetic switch 5 and the cross-heads return. If a stop button 13 is depressed, the working motor circuits are immediately opened and dynamic braking circuits are established, followed by closure of the switch 5 and return of the cross-heads to their top positions. After such stoppages, a maintaining-circuit is made through a stop relay 6 which necessitates the depression of a re-set push-button 17 before the motors can be re-started. The depression of the re-set button gives visible and audible signals by means of a relay 11 acting to switch on flash lamps, horns, &c. A safety pushbutton 15, by energizing a safety relay 8, provides for a temporary stop at any time without other interference with the control. An " inching " button 16 by energizing an inclining-relay 7 starts the small motor but leaves the rheostat switch unmoved. Contacts 30 resting upon the paper band and controlling a relay 9 are adapted to stop the motors in case the paper breaks. Several sets of push-buttons may be provided so as to allow control from different points. Slightly modified arrangements have additional contacts on the inching relay for the purpose of rendering repetitions of the inching action impossible unless the re-set button is depressed each time.
