Title: Improved operative tool for well-boring
IPC: E21B10/26
Filed: 1923-01-08
Abstract: 215,051. Jenkins, R. F., and Price, D. W. Jan. 8, 1923. Bore-hole apparatus.-In a well boring tool wherein advance cutters bore a hole and are followed by expanding reaming cutters which enlarge the hole, the advance bit comprises a body carrying an axial drill and one or more cutters cutting concentric annuli around the hole formed by the axial drill. The boring rods 26 are slidably and non-rotatably connected to an underreamer body 16 by a plunger 24 of square cross-section, the sliding motion being limited by pins 28 ; when in its lowest position, the plunger acts through lower bevelled surfaces and wedges 22 to hold in expanded position arms 18 pivoted at 19 in recesses in the bodv 16. The enlarged lower ends of the arms 18 have radial dovetail slots receiving tools 21 which are locked by dovetailed plates 21'; projections 18<1> on the enlarged lower ends engage recesses 18<2> in the body 16 to limit the movement of the arms 18. Below the body 16 is a bodv 1 with a central drill 2 held in a dovetail groove ; the body 1 is of substantially diamond shape in cross-section and at the end of each diameter is a cutter 7 adjustably held in grooves by a screw and slot connection. The bodies 1, 16 may be integral or separable, and in the latter case the body 1 may be capable of attachment to the boring rods 26. A central water passage communicates with four divergent holes 31 in the body 1.

Abstract: 819,526. Moulding concrete blocks &c. SNELL, R. G. Jan. 7, 1957 [Jan. 9, 1956], No. 641/56. Class 87(2). Apparatus for moulding concrete cavity wall building units comprises an upright support 1 for a pallet 3, mould box walls 4A, 4B slidably mounted on the support so as to be movable vertically between a raised position, Fig. 1, in which the walls and pallet together form a mould box and a lowered position in which the walls lie clear of the pallet and moulded unit so that the latter may be removed from the apparatus, and core means 7, 8 and 9 movable with the mould box walls and passing through apertures provided in the top of the support and in the pallet. The mould box walls are held in their raised position, Fig. 3, by opposed plunger rods 13 which are spring-urged apart so as to project through holes provided in the support walls. These plunger rods may be pushed inwards clear of the bottom edge of the mould casing 4 to permit lowering thereof by pivotal arms 14 mounted on the mould box walls and having operating handles 15. When it is desired to form a block having external and internal facing surfaces of different constitution from that of the main portion of the block, these can be moulded simultaneously with the block by the use of vertical partition members spaced the required distance from the side walls of the mould box.

Title: Improvements relating to the manufacture of sulphanilamide derivatives
IPC: C07C311/37
Filed: 1944-01-17
Abstract: Sulphanilamidobenzamides of general formula: H2N.C6H4.SO2.C6H4.CO.NH2 are obtained by hydrolysis of the corresponding nitriles so controlled that the hydrolysis is arrested before the corresponding carboxylic acids are formed.  In an example, 4-sulphanilamidobenzonitrile is prepared by adding acetylsulphanilyl chloride to a solution of 4-aminobenzonitrile in pyridine, heating for 1 hour on the water-bath, removing excess pyridine under reduced pressure, boiling the residue with 50 per cent sulphuric acid to obtain a clear solution from which the nitrile product is precipitated by pouring on to ice and neutralizing, treating a cooled solution of the powdered product in glacial acetic acid with concentrated sulphuric acid, cooling rapidly, allowing to stand for 16 hours, neutralizing in ice-water and purifying the precipitated 4-sulphanilamidobenzamide by reprecipitation from ammonia and recrystallization.

Title: Improvements in the production of synchronising impulses in television and the like
IPC: B64C39/00
Filed: 1934-01-10
Abstract: 431,521. Television. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, and SCHLESINGER, K., 39, Friedrichstrasse, Friedrichshagen, both in Berlin. Jan. 10, 1934, No. 870. Convention date, Jan. 10, 1933. [Classes 40 (iii) and 40 (v)] Synchronizing impulses are produced by a phonic wheel 1 producing impulses approximately correctly spaced, which excite a circuit 8, 9 giving oscillations exactly spaced but not of the required form, which control a gasdischarge tube 11 supplying the synchronizing impulses of correct spacing and form. The phonic wheel is driven by a synchronous motor, and the coil 2 is loosely coupled to the oscillatory circuit 8, 9 which may be tuned to a harmonic. The tube 11 is given such a grid-bias 22 that anode current is passed only at the peaks of the oscillations from the circuit 8, 9. The anode is supplied from a condenser 14, which is charged through a resistance 18 in a time corresponding to the scanning of two or three points of a television image. The imagechange impulse is produced by connecting a condenser 15 in parallel with the condenser 14 by contacts 3 on the phonic wheel. The charging period of the condenser 15 is slightly less than the scanning-period of a line. The transverse position of the image is adjusted by a fine rotary adjustment of the coil 2 about the axis of the wheel. The image phase and the duration of the connection of the condenser 15 are adjusted by using trapezoidal contacts on the wheel which can be shifted relatively to one another and about the axis of the wheel, Figs. 2 and 3, (not shown). The synchronizing impulses modulate an oscillator 23 tuned sharply to an intermediate frequency which modulates the carrier frequency.

Abstract: PURPOSE: To make the cost of equipment inexpensive and enable controlling flow rate of quantity of water without using any measuring instrument in such a way that either a pressure detector or a flow detector is used, and pressure control is done at a presumptive end using a microcomputer.  
     CONSTITUTION: In a step 109, comparing scrutinies between present discharging pressure of a pump which has been memorized by means of a step 105 and a discharging pressure as being a new target which has been sought by means of a step 104, in case where there is any difference between the both, and new operating velocity in such a way that addition processing is done to its operating velocity which is memorized by means of a step 109 ahead as much as the predetermined width of changed velocity Δn. For example, in case where discharging pressure which has been sought out by a step 114 from the discharging pressure memorized by means of the step 105, operating velocity in which present operating velocity has been decelerated behind as much as the width of changed velocity Δn is newly memorized. Velocity operation of the pump is done by means of repeating said steps. Thus, it leads to enable performing control which is stable in the pressure at the presumptive end, and remarkably reducing the cost of equipment.

Then, a code indicating a syntax error is generated in an interpreter data storage buffer 5. When the data is registered in the table 3, on the other hand, modifier data is read out of a modifier table 6 corresponding to the basic predicate data and whether there is corresponding modifier data in a buffer 2 or not is judged.
