Title: Apparatus for applying a sewing rib to an insole
IPC: A43D43/06
Filed: 1959-02-26
Abstract: 911,285. Rib attaching. SMALL, E. F. Feb. 26, 1959 [Feb. 27, 1958], No. 6789/59. Class 17 (1). A rib-attaching machine comprises a support 14 for a major face of an insole, an edge guide member or members 68, 70, guide means 18 for guiding the rib on to the other major face of the insole and means 20 for pressing the rib on to the insole and advancing the insole against the support 14 and edge guide 68, 70 to progressively lay the rib, the pressing and advancing means comprising a pair of feed feet for engaging the rib and means for moving the feet cyclically in out-of-phase relation with a cycle comprising a component of motion normal to support 14 and an arcuate movement about an axis normal to support 14. The machine possesses a head casting 12 in which a shaft 24 is slidably and rotatably mounted, the shaft carrying a sleeve 26 and integral arm 30. The distal end of arm 30 carries a sleeve in which the support 14 and associated edge guides 68, 70 are spring- mounted on a shaft 40. Lock-nuts 46 threaded on shaft 40 allow the compression of spring mounting 44 to be varied. On the other end of shaft 24 an arm 54 carrying an eccentric cam surface 62 is journalled. Cam face 62 abuts casting 12 so that when arm 54 is moved in the plane of the machine, as shown in Fig. 1, the support is moved towards or away from the feeding mechanism. If arm 54 is moved in a plane perpendicular to that of Fig. 1, support 14 and edge guides 68, 70 move relatively to rib guide 18, thus allowing the rib to be applied to any part of the face of the insole. The pressing and feeding means 20 are mounted on concentric sliding cylinders 74, 76, collars 94 and 98 of which carry ball-bearing assemblies 100. A rotatable shaft 102 carries eccentrics 104, 106 which co-operate with assemblies 100 so that, when shaft 102 is rotated by motor M1, the cylinders 74, 76 move in out-ofphase relationship along their common axis and angularly with respect to each other. These movements press the rib against the support and advance the insole. Rib guide 18 is pivotably mounted on one end of a bell-crank lever 138, the other end of which abuts a spring-loaded shaft 150 and cutter 157. The construction of the rib guide is such that on its movement away from the working region the rib slides freely in the guide whereas in its movement towards the working region the rib is clamped in the guide. Movement of handle 54 to the position shown in Fig. 1 trips a switch S1 which starts motor M1 and thus initiates a cycle of operation. The movement of handle 54 back to its rest position trips switch S2 through links 174, 172, 168 to initiate the movement of guide 18 away from the working region. This movement effects the depression of shaft 150 and cutter 157 by lever 138, thus bringing the cutter into engagement with the rib to sever it.

Title: Improvements in or relating to the manufacture of cheese
Inventor: FEIX ROBERT
IPC: A23C19/05
Filed: 1934-03-03
Abstract: To increase the stability of cheese, the manufacture of the cheese is carried out in the presence of pectin, e.g. by adding pectin at the same time as the rennet, or pectin is added to the curd after it has been freed from whey.  The pectin may be in the form of extract, or of powder which may be added as such or in solution.ALSO:To obtain a stable, homogeneous cheese of full round flavour, pectin is added in the manufacture of the cheese, e.g. at the same time as the rennet, or after the curd has been freed from whey. The pectin may be employed in the form of extract or of powder which may be added as such or in solution.  The addition of pectin enables a lower temperature, e.g., about 10 DEG  C., and rarely exceeding 16 DEG  C., to be used in separating the curd by means of rennet, thus checking the development of injurious micro-organisms.  Where the pectin is added after separation of the curd, the curd may be obtained by treating cream or whole or skim milk with rennet or with an acid such as hydrochloric or citric acid or by means of lactic fermentation, and is then strained through cloths and treated with 0,1-5 per cent of a 10 per cent pectin extract, the amount of pectin used being larger according as the acidity is higher.

Title: Improvements in or relating to fuel feeding arrangements for nuclear reactors
Inventor: SKIPPER REUBEN GEORGE SANDY
IPC: G21C19/08
Filed: 1959-02-27
Abstract: 916,820. Servicing reactors. GENERAL ELECTRIC CO. Ltd. Feb. 29, 1960 [Feb. 27, 1959], No. 6935/59. Class 39 (4). In a reactor in which fuel element channels in the core are refuelled from their lower ends whilst the reactor is in operation the fluid coolant is arranged to enter that channel which is being serviced at a lower temperature than that entering the remaining channels whereby the mass flow of coolant through that channel may be reduced thereby reducing the risk of blowing a fuel element out of that channel during the withdrawing of a stack of fuel elements. As shown, the reactor pressure vessel 1 has a number of standpipes 3 (only one shown) depending therefrom, each fuel element channel in the core (not shown) having an extension 23 to which a swivelling duct 7 of a charging machine 2 may be coupled. The charging machine is as described in Specification 844,764 and has a charge tube 8 which may be extended from the charging machine vessel 9, a flange 5 on the vessel 9 making a gas-tight connection with a flange 4 in the selected standpipe 3. The duct 7 forms a continuation of a duct 10 with which a tube 11 may be aligned, the tube 11 being one of a number of similar tubes provided by a fuel element storage magazine. A tube 12 houses a chain which conveys the fuel elements from or into the tube 11 and along the duct 10. The chain may be as disclosed in Specification 893,487. A tube 16 interposed between the duct 10 and tube 8 extends through a header 17 coupled by ducting 18 to a water cooler 19. In operation the vessel 9 is gas-pressurized to a pressure similar to that in the reactor vessel 1, a valve in the flange 5 is opened, the duct 7 is connected to the extension 23 and a blower 20 is started. Gas is thereby withdrawn from the vessel 1 through the space between tubes 8, 16 and enters the cooler 19, part of the gas leaving through duct 22 and entering vessel 9 and part leaving through duct 21 and passing through tubes 11, 10, 7, 23 to cool the fuel element channel. The gas in vessel 9. returns partly through the space between tubes 10, 16 and partly through the space between tube 8 and standpipe 3. This gas provides a cool buffer between the cool returning gas in tube 10 and the hot entering gas and also prevents overheating of the standpipe and concrete shield 14. Specifications 785,945 and 789,022 also are referred to.

Title: An improved process and apparatus for cracking hydrocarbons
Filed: 1927-03-14
Abstract: 274,763. Arnold, C., (Standard Development Co.). March 14, 1927. Hydrocarbons, cracking.-Relates to cracking hydrocarbons, particularly the residuum of high grade crude oils which have been distilled for the removal of gasoline, and consists in heating the oil to a cracking temperature in a coil 23 and then passing it into an enlarged thermally insulated region 27 wherein it undergoes cracking under pressure, the clacked product being passed at reduced pressure directly and without substantial loss of heat into a chamber 1 connected to a bubble-tower 5, heat being supplied to the chamber 1 in order to increase the yield, of gas oil. Cooling fluid, preferably the oil to be cracked, is supplied to a coil 8 in the bubble-tower and passes thence to a cooler 17 for cooling tar delivered from the chamber 1 through a valve 19. The cooler 8 may be byepassed by means of valves 14<1>, 15<1>. The distillate from the bubble-tower is delivered through a pipe line 9 for subsequent fractionation, the gas oil being taken off as a separate fraction by means of a pan 7 and a line 11 provided with a valve 12. A cooler 8<1> through which the gas oil passes on its way to a tank 13 is served by a bye-pass from the stock oil flowing from the cooling coil 8. A pump 22 fed by the stock oil after it has been preheated in the various coolers delivers the oil under pressure to the cracking coil 23 mounted in a furnace setting 24. The cracking is completed in thermally insulated drums 27 arranged in series or in parallel and controlled by valves 26. Vapour and liquid together are discharged from the drums through a pressure controlling valve 36 to the chamber 7 which is preferably heated wholly or partly by internal flues 3 to minimize coking. The gas oil may be mixed with the original stock to form a new stock for the same cracking oil, or it mav be cracked in a separate operation. The tar from this operation may bo blended with the tar from the original stock to yield a fuel oil product. Numerical data of working pressures and temperatures and of approximate percentage yields are furnished in the Specification.

Filed: 1975-02-21
Abstract: 1507872 Inventing ROBAND ELECTRONICS Ltd 19 Feb 1976 [21 Feb 1975] 7490/75 Heading H2F [Also in Division G3] A circuit for producing an A.C. supply voltage of predetermined waveform includes a D.C. source with each of its terminals connected through a respective switching regulator. The regulators are switched at a high frequency compared with the desired A.C. voltage, and are controlled by error signals representing differences between a reference voltage having the predetermined waveform and the actual output voltage of the circuit. As shown in Fig. 1, each pole of a D.C. source 1 is connected through a respective switching regulator 2, 3 to an output terminal 4, 4<SP>1</SP>. The regulators receive reference voltages from a source 5 in the form of antiphase voltages of the required output waveform. A D.C. bias arrangement 6 ensures that the A.C. output voltage at terminals 4, 4<SP>1</SP> is balanced relative to ground. Each regulator 2, 3 may include a series transistor 12, Fig. 2, switched by a transformer 17 and auxiliary transistor 18 in response to a comparator 31 receiving an A.C. reference voltage 35, D.C. balancing voltage 36, and a feedback voltage from the A.C. output terminal 4. The output of the comparator 31 controls a pulse duration modulator 40 including a high frequency oscillator 41 and monostable trigger circuit 42. The A.C. reference voltage 35 may be derived from a phase-locked loop, Fig. 3 (not shown), including a memory device storing successive elements of a sinusoidal waveform which is interrogated at a desired frequency. An alternative form of regulator, Figs. 4-5 (not shown), is suitable for use with reactive loads and includes a circuit which compares an error voltage with a ramp signal, and a NAND gate inventer circuit which ensures that transistors connected to the two poles of the D.C. source 1 are never simultaneously conductive. A three-phase embodiment is briefly dscribed. with reference to Fig. 6 (not shown).
