Title: Improvements in or relating to coin freed apparatus for dispensing drinks or other liquids
IPC: G07F13/10
Filed: 1949-07-15
Abstract: 673,898. Coin-freed apparatus for dispensing drinks in cups. PAMMENT, F. T. Aug. 8, 1949 [July 15, 1949], No. 18681/49. Class 27 In a coin-freed apparatus for dispensing a measured quantity of a drink and a paper cup to receive it, a stack 19, Fig. 3, of the cups is supported by the rear end of a coinfreed manually-reciprocable slide 2 which, when thrust in, detaches the lowermost cup 19 by means of a fork 13 and discharges it through an aperture 11 to a delivery shoot 20, stops 12 on the slide then supporting the remainder of the stack pending return outward movement of the slide. The fork 13 is pivoted to the slide at 14 and has a depending arm 16 which, when the slide moves in, engages a stop 17, causing the fork to pivot downwardly against the action of a spring 15 and to detach the lowermost cup 19. The liquid is dispensed on the return of the slide for which purpose it is fitted, on either side, with an inclined arm 3, Fig. 1, having a slot 4 engaged by a pin 7 on one arm 6 of a pair 6, 6* freely pivoted on a fixed bracket 5 and connected by a tension spring 10. Each arm 6* terminates in a fork 8 engaging the actuating rod 9 of a dispensing valve 23: the valve is of a known type adapted to screw into the neck of a bottle which is then inverted, a measured quantity being discharged when the rod 9 is raised (e.g. by the rim of a glass) and the measure within the valve refilling when the rod 9 is released and lowers. When the slide 2 is moved in, each arm 3 snaps over the arms 6, 6* to the lower position (shown in broken lines) to lower the valve rod 9 to refill the valve measure. On the return of the slide 2, the arms 6, 6* snap back and return the valve rod 9 to discharge the measured quantity of liquid. The two valves 23 are associated respectively with a tank 21 for cordial and a water tank 22, Fig. 5, and discharge into a common outlet pipe 25.

Title: A core for a dynamo electric machine
IPC: H02K15/12
Filed: 1943-11-10
Abstract: 604,664. Dynamo-electric machines. SIGMUND, F., and HLAVIN, W. S. Nov. 10, 1943, No. 18709. [Class 35]  Rubber-like material is applied to the winding in the slots of a laminated core to envelope the windings and bond with a previously applied coating of similar material covering the core surface, including the slot walls and open ducts for cooling fluid are formed in the surface of this material facing the air-gap in the slot mouths. Alternate laminae may be dipped in or sprayed with insulation, and when dry, a coating 11 is applied over the whole core surface and the windings are placed in the slots.  The individual turns may also be coated with rubber or the like and the core is then placed in a tightly-fitting container and a further quantity of insulation is forced in to fill the slots. In this operation a mandrel with axial ribs is pushed into the stator bore and the ribs cause ducts 36 to be formed in the slot mouths. A further coating may then be applied by dipping over the core surface, including the end windings but the thickness of this over the teeth may be reduced by machining. During the dipping a layer of powdered mica or asbestos may be interposed between successive rubber layers. The ducts 36 may be lined with zinc or lead which may also coat the end windings (layer 37). The composition of the various insulating layers may differ somewhat. Specification 574,491 is referred to.

Abstract: 1,269,605. Making IGFETs. SIEMENS A.G. 21 April, 1970 [22 April, 1969], No. 18922/70. Heading H1K. In the production of an IGFET, the gate insulation is formed on a body already containing diffused source and drain regions and the gate metallization is applied with no intermediate processing steps and using electronbeam evaporation. Such a method avoids contamination of the gate insulation. Two methods are described; each starts -with a transistor body having heavily doped source and drain regions and to which is applied a fresh silica layer on which is then deposited aluminium by electron beam evaporation. Both methods subsequently involve photoresist masking and etching and deposition of aluminium for the source and gate electrodes; in one of them further aluminium is deposited on the gate electrode.

Title: Improvements in regulating arrangements for synchronising the individual motors of amulti electric-motor drive
IPC: H02P7/26
Filed: 1931-07-01
Abstract: 376,489. Maintaining defined speeds of motors. SIEMENS - SCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. July 1, 1931, No. 19007. Convention date, Aug. 16, 1930. [Class 38 (iii).] A motor 1 of a paper-making machine is maintained at a speed proportional to the frequency in a control circuit 19 by an interrupter 11 driven by the motor and two thermionic valves 31, 32. At correct speed, the interrupter 11 connects the grids of the valves to the circuit 19 at the zero of the control cycle, and thus neither valve conducts. If the speed deviates, then the interrupter impresses a positive potential on one grid and a negative on the other. Thus one valve conducts and energizes an auxiliary field 21 of the motor and also closes a relay 29 or 30 to cause a pilot motor 27 to adjust the main field 20.

Title: Monoisopropylaminoborane polymers
Inventor: SCHAEFFER GEORGE WASHINGTON
IPC: C08G79/08
Filed: 1957-06-17
Abstract: New polymers of monoisopropylamino borane having the empirical formula C3H7NBH are prepared by heating monoisopropylamino borane [for preparation of which see Group IV(b)] to a temperature of at least 250 DEG C. and holding the temperature between 250 and 350 DEG C. for such a time that the total heating and holding time is at least five minutes.  Crystalline polymers are produced if the initial heating takes place within 5 minutes and the total heating and holding time is not more than 15 minutes.  On the other hand amorphous, glass-like polymers are produced if the initial heating takes at least 30 minutes, and if the temperature is held for at least a further 5 minutes, provided that the total heating and holding time is not more than 75 minutes.  During the reaction hydrogen is given off and the resultant polymer is insoluble in conventional solvent but may be hydrolysed by conc. HCl at 100 DEG C. Examples are given.  Use.  Covering wire for electrical insulation.ALSO:Monoisopropylaminoborane is prepared from isopropyl ammonium chloride and lithium borohydride by reacting the solids under diethyl ether in a modified Kjeldahl flask with evolution of hydrogen.  The ether is then removed by warming under vacuum; the tube is closed and heated to 120 DEG C. for 30 minutes, and is again evacuated and closed, this time being heated to 200 DEG C. for a further 30 minutes.  When the tube is opened to a vacuum pump, N-tri-isopropylborazine is collected at-196 DEG C. in the adjoining trap, and solid monoisopropylaminoborane (yield 10%), primarily in the dimeric form, is deposited on the cool upper walls of the reactor.  Monoisopropylaminoborane is then heated at temperatures of at least 250 DEG C. to produce high polymers (see Group IV(a)).

Filed: 1925-07-27
Abstract: 238,866. Middelboe, K. Aug. 21, 1924, [Convention date]. Ball-and-ring mills; roller-and-ring mills. - In a mill with roller action between two grinding-rings revolving coaxially in relation to each other and with rotary grinding-bodies arranged between the rings, the inner ring being divided by radial cuts or joints into sections separably movable in a radial direction, each of the cuts or joints forms wholly or partially an angle to the axis to enable the balls, rollers, &c. to pass gradually from one section to the next. The sections of the inner ring have a peripheral length which is approximately double the peripheral distance between the lines or points of contact of the ring with two adjacent grinding-bodies. The cuts between the sections may be such as to give the joints in the grinding-ring a helical form, and the helices may be arranged in opposite directions on opposite sides of the central plane of the ring as shown in Fig. 2. Fig. 3 shows the joint formed as a broken line with three parts parallel to the axis and the two parts at right-angles to the axis and parallel to each other. In Fig. 4, the ends and junction points of the helices are rounded. In Fig. 5, the ring is divided into portions by cuts at right-angles to the axis and so that the joints between the portions of each section are displaced relatively to the joints between the portions of the adjacent sections.

Filed: 1958-06-16
Abstract: 931,792. Finishing yarns. DEERING MILLIKEN RESEARCH CORPORATION. Sept. 2, 1959 [June 16, 1958], No. 19207/58. Drawings to Specification. Class 120 (3). Modified stretch-bulk/properties are imparted to thermoplastic multifilament yarn by bring- ing the yarn to a state of latent and/or actual stress, e.g. by (false-) twist crimping, edgecrimping, passage between (heated) corrugated rollers, knitting into a fabric and then unravelling, with intermediate heat-setting and/or cooling and/or storing under tension, and then, continuously or after a time interval, overfeeding the yarn into a heated zone. While the yarn is in such zone, non-rectilinear forms e.g. undulations, loops, coils, develop in the filaments. On leaving the zone, the yarn is passed through positive advancing apparatus prior to at least one further operation, e.g. plying or winding, on the yarn. Heating, up to a temperature close to the sticking temperature of the yarn may be effected by a heated stationary surface over and in contact with which the yarn passes, passage of yarn through, or subjection to a stream of, hot fluid, or the yarn may be subjected to radiant heat. Specification 852,133 is referred to.

Title: Surface Control of Sub-Surface Well Valving using Flow Passing Tubing Link
Inventor: PAGE JOHN SPLAWN JR
IPC: E21B34/10
Filed: 1967-04-26
Abstract: 1,181,095. Wells &c. J. S. PAGE. 26 April, 1967 [28 April, 1966], No. 19222/67. Heading E1F. A subsurface flow control valve is opened and closed by reciprocating tubing through which the flow passes, a pressure operated actuator for reciprocating the tubing being installed at the wellhead. The actuator 160 has a piston 161 normally subjected on either side to the well pressure, the areas of the sides being such that the tubing 173 is held down and the control valve is open. In the event of pressure leakage from the well, a pilot valve 201 is actuated to vent the chamber 167 above the piston so that the tubing 173 is lifted to close the control valve. The tubing 173 forms an extension of the actuator and slides within fixed tubing 184. The tubing 184 is fixed and sealed to the well casing 176 by hydraulically set slips 340 and a packer 315, flow to the annulus above the packer being stopped by a sleeve valve 328 carried by the tubing 173 when the control valve is closed. The control valve includes an insert 185 removably fixed in the tubing 173 and having a valve seat 209 which is engaged by a ball 193 to close the control valve. When it is desired to open the control valve fluid pressure is applied on the upper surface of the ball, and the tubing 173 with the seat is lowered by applying pressure to the upper side of the piston to trap the ball as shown. In another construction the control valve is closed or open when the tubing is respectively in its lower or upper positions. In a modification in which the well produces from two zones (Fig. 1, not shown) the actuator piston is normally subjected to the pressure from the lower zone on the lower side and the upper side is vented. If the tubing supplying the pilot valve controlling the actuator is torn away, or the well pressure from the lower zone falls below a given pressure, both sides of the piston are vented and the tubing falls under its own weight to close the control valve.
