Title: Improvements in or relating to apparatus adapted for use in shoemaking
IPC: A43D25/12
Filed: 1961-06-29
Abstract: 986,264. Shoe bottom presses. BRITISH UNITED SHOE MACHINERY CO. Ltd. June 29, 1961 [June 30, 1960; Sept. 19, 1960], No. 23504/61. Heading A3B. A pad box 8 comprises a number of forepart pad layers 30, 32, 34, 36, 38 supported in a rigid frame 6 and a resilient shank and heel breast pad 44 so that a sole unit 10 can be pressed against the forepart and shank portion of the shoe bottom and the breast of a heel previously attached to the shoe bottom, adhesive having been applied to the sole unit and shoe bottom. A plane basal surface 48 of the heel pad 44 rests on a rigid block 70 engaging with the frame 6, both the pad and the block being positioned in an opening 39 provided in the pad layers 32-38. A leather cover 89 extends over shank and heel member 44 and the outer forepart pad 30 which is provided with a depression 56 to co-operate with the ball portion of the shoe. Toe and heel engaging members 86, 88 hold the lasted shoe against the pressure of the pad box as it is raised by the piston 82. The rigid frame 6 comprises three members 22, 24, 26, adjustably secured together and upon which the innermost forepart pad 38 rests. The four inner pads 32, 34, 36, 38 extend rearwardly beyond the heel of the shoe. The heel of a shoe can extend into a space 62 between two rearwardly extending basal portions 60 provided on the pad 44 and further into the opening 39 if the heel is sufficiently high. The apparatus also comprises a resilient heel supporting member 74 which moves into engagement against the rear outer surface of the heel as the piston 82 is raised to apply pressure to the sole unit. Ribs 76 provided on the heel member 74 interlock with grooves 78 provided in a strip 79 of greater hardness than the layer 32 and cemented thereto. The pad member 44 can be replaced by similar members belonging to a set in which there is a progressive variation in the dimensions of successive members, thereby adapting the apparatus for a different range of sizes and styles of shoes. The frame members 22, 24, 26 can be moved relative to one another to accommodate small variations in the distance from the heel breast to the ball portion between shoes of a particular style. A modified shank and heel pad (Fig. 12) comprises a discontinuity 130 which extends across the member from side to side and which acts to close any gaps between the sole unit and the shoe bottoms adjacent the heel breast. The pad member also comprises two ridges 161 extending either side of the shank portion and heel breast of the shoe to reduce the risk of margins of the breast flap being pressed around the sides of the heel adjacent the heel breast. A second modified form of shank and heel breast member similar to that shown in Fig. 12 is provided with channels extending along the outer side of each ridge so that material of the ridges flows into the channels when the member is compressed. Specification 936,294 is referred to.

Title: Improvements in and relating to float valves
IPC: F16K47/02
Filed: 1952-09-19
Abstract: 742,391. Ball-and-float valves. CARMALT, L. H. Dec. 21, 1953 [Sept. 19, 1952], No. 23617/52. Class 135. A ball-and-float cistern-supply valve has, in the connection between the float arm 1 and the bell-crank lever 12 which actuates the valve plunger, an overcentre device comprising a weight or spring 8 and a pivoted arm 6, and a push-pull link 11. The float arm 1 is pivoted at 2 to a pair of fixed parallel fingers 3, and the arm 6 is also pivoted at 2 to arm 3. When the float falls from the position shown, spring 8 moves below its dead centre position, and arm 6 snaps over in a counter-clockwise direction and link 11 is pushed down to cause lever 12 to open the valve. The valve is snap-acting in both directions. Series of holes in the arm 6 and link 11 allow the pivoting point between these two members and, hence, the sensitivity of the overcentre device, to be varied. In a modification, a multiplying gear train is interposed between the float arm and the adjacent end of the spring.

Title: Improvements relating to electrical protective relay systems
Inventor: HILL ANTHONY
IPC: H02H3/38
Filed: 1967-05-23
Abstract: 1,222,360. Protective arrangements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 16 May, 1968 [23 May, 1967], No. 23921/67. Heading H2K. In a protective arrangement, e.g. a distance protective arrangement, having a phase comparator for effecting a phase comparison between two A.C. input signals S 1 , S 2 , the comparator being of the "push-pull" type and supplying two pulses per input cycle to a pulse integrator PI, a second integrator GI integrates the gaps between the pulses to produce an output causing resetting of the pulse integrator PI when the gaps vary from a predetermined width, so. as to prevent incorrect operation of the arrangement should D.C. transients cause the comparator to supply one long pulse per cycle. In the arrangement shown, a signal unit S, connected to current and voltage transformers CT, VT, supplies the positive half cycle of the signals S 1 , S 2  (e.g., S 1 -V-IZ and S 2  = V) to an "AND" gate G1 and the negative half cycles to an "AND" gate G2. When the signals are coincident the AND gates provide output pulses to an "OR" gate G3 which is connected to both integrators PI, GI. When the phase angle between the signals is less than 90 degrees, the pulses are of sufficient length for the pulse integrator to provide an output of sufficient magnitude for a level detector LD and an amplifier and pulse lengthener APL to operate a trip relay R. When the phase angle between the signals is more than 90 degrees (e.g. 108 degrees) due to a D.C. transient or the absence of a fault condition, the gap integrator GI and associated level detector LDG provide a reset signal to the pulse integrator to prevent integration of the pulses. The circuit elements indicated are diode/transistor and resistor/ capacitor circuits, Fig. 2 (not shown).

An organic reducing agent, a wetting agent, preferably non-ionic, and a dispersing agent may also be present.  The water-soluble cellulose adhesive may be that sold under the Registered Trade Mark "Polycell." Preferred proportions in the dried film are 90-98% sodium nitrite, 2-10% "Polycell" or other water-soluble cellulose adhesive (4-10% where the solution is to be applied by dipping or flow coating), and less than 1% of cationic or non-ionic wetting agent, dispersing agent, organic reducing agent or mixtures of these.ALSO:An anti-rust coating composition comprising an aqueous solution of sodium nitrite, and a water-soluble cellulose adhesive, and, optionally, an organic reducing agent, a wetting agent, preferably non-ionic, and a dispersing agent, is applied by brushing, spraying, flow coating or dipping to ferrous surfaces and air dried, or dried by storing or hot air blasting to yield a thin continuous adherent film which provides good protection against atmospheric corrosion, and has no appreciable adverse effect on the friction properties of such surfaces as clutches, brake drums and brake discs when in use.  The coating need not be removed from working surfaces since the initial application of the brake or clutch is sufficient to remove it.  Lubricated ferrous surfaces, e.g. bearing races may be similarly coated.  The dried coating withstands normal handling in transport and storage of the article to which it is applied, and the coated article may be moved while the applied coating is still wet.  The water-soluble cellulose adhesive may be that sold under the Registered Trade Mark "Polycell". Preferred proportions in the dried film are 90-98% sodium nitrite, 2-10% "Polycell" or other water-soluble cellulose adhesive, (4-10% where the solution is to be applied by dipping or flow coating), and less than 1% of cationic or non-ionic wetting agent, dispersing agent, organic reducing agent or mixtures of these.

Title: Improvements in molten salt bath furnace
IPC: C21D1/46
Filed: 1948-09-15
Abstract: 640,860. Electric salt bath furnaces. AJAX ELECTRIC CO., Inc. Sept. 15, 1948, No. 24202. Convention date, March 13. [Class 39(iii)] A salt bath is heated by passage through the salt of current between electrodes 32 which pass through the walls of the bath and are entirely submerged in the molten salt, but when the salt solidifies on cooling the tops of the electrodes are exposed due to shrinkage of the salt e.g. barium chloride, from a level 51 to a level 52. Starting of the melting is facilitated by applying powdered carbon between the electrodes or by fusing the surface of the salt with a torch. Several pairs of electrodes 32 are mounted in a deep bath at different levels so that current passing between upper electrodes melts the salt between the next adjacent lower electrodes to form a conductive path between them. The pairs of electrodes may be in vertical columns or in echelon as in Fig. 15. The electrodes of each pair are closely spaced e.g. ¢-2 ins. The vertical spacing between pairs of electrodes is less than 2 ft. and is less than six times the space between the electrodes of a pair. The electrodes are L-shaped and are rectangular in cross section, and the horizontal parts 31 of each pair are mounted on the outer sides of the vertical parts 32 and are water-cooled by pipes 45, to which current may be fed. The electrodes lie against or may be partly set in the refractory wall 22 of the bath or may be set in so that the outer faces of the electrodes are flush with the wall 22. If a metal vessel is used, the electrodes are spaced well away from the walls, and the horizontal electrode parts 31 pass singly or in pairs through a refractory packing in metal-rimmed apertures in the walls. Metals such as magnesium or aluminium may be melted to form a floating mass on the salt, and a slat may float on the metal. If the bath is to be cooled, the metal is first poured off, or a lower voltage is used in starting until the electrodes are entirely submerged in the molten salt. Stirring of the molten salts occurs as described in Specification 515,227.

Title: Electric-discharge machining apparatus
IPC: B23H7/18
Filed: 1961-07-05
Abstract: 909,171. Automatic control systems for spark-erosion. GENERAL MOTORS CORPORATION. July 5, 1961 [July 19, 1960], No. 24273/61. Class 38 (4). [Also in Group XXII] An electro-erosion apparatus has its erosion gap fed through a rectifier 46 and transformer 40 from a parallel resonant storage circuit 50 supplied with alternating current from a source 30. The latter is preferably a highfrequency electronic oscillator or a motor generator which feeds the storage circuit 50 through an input transformer 32 and inductor 60. Storage circuit 50 is a tank circuit comprising a tunable capacitor 48 in parallel with the primary winding of the output transformer 40. Alternatively a separate inductive reactance winding may be used. Both transformers 32, 40 may have adjustable ratios or the output transformer secondary windings may have variable coupling with the primary winding. The transformer 40 has two secondary windings 42, 42<SP>1</SP> connected through rectifiers 46, 46<SP>1</SP> which may be full or half wave, and minimum inductance conductors 44, 44<SP>1</SP> with separate erosion gaps between electrodes 14, 14<SP>1</SP> and the workpiece 12 which is immersed in a dielectric. For some applications the rectifiers 46, 46<SP>1</SP> may be omitted. Rectifiers 54, 54<SP>1</SP> are connected across the gaps to minimise reverse flow therethrough. The gap length is adjusted automatically by liquid pressure motor 19 controlled by a servo valve 24 responsive to a differential pulsating voltage derived from a summing circuit 62 to which is applied a pre-set reference voltage from source 68, and a control voltage derived from a tapping made through rectifier 66 and resistance 64 with the storage circuit 50. The latter has a voltage which varies with the voltage across the gap. A switch 75 is actuated by a cam 76 driven by a motor 78 to cause intermittent interruption of the control voltage and corresponding withdrawal of the electrodes 14 for clearing debris from the gaps. In another embodiment, Fig. 3 (not shown), a single input transformer 32 feeds a plurality of parallel storage circuits 50 each feeding separate workpieces and electrodes through separate transformers. The polarity of the workpieces and electrodes is reversible. The workpiece may be moved instead of the electrode.

IPC: G05D3/12
Filed: 1947-09-04
Abstract: 657,677. Non - - contact - making relays. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Sept. 4, 1947, No. 24412. [Class 40 (iv)] [Also in Group XXXVIII] A magnetic amplifier supplying alternating current to a load includes a feed-back winding having a non-inductive resistance in series to decrease its time constant. In the embodiment shown, a field winding 8 of an induction motor is energized by the output from such an amplifier in accordance with the polarity of a controlling signal conveyed by lines 34 to the primary 33 of a transformer 23. The output from each of the secondaries 22, 31 of the transformer 23 after combination with a biassing voltage from the supply mains 7b is rectified and applied to windings 18, 19, and 27, 28 on magnetic cores A, A<SP>1</SP> and B, B<SP>1</SP> respectively, the magnetic effect of the biassing voltage being counterbalanced by a D.C. potential applied to the windings 47-50. The arrangement of the secondaries is such that in one combination the voltages are additive and in the other subtractive according to the phase of the controlling signal. With no signal applied to the transformer 23, the impedance of the coils 14, 15 and 16, 17 will be equal and no current will flow in the field winding 8, but a signal voltage will unbalance the currents through the right-hand and left-hand circuits resulting in the flow of a field current determined by the value and phase of the control current and by the effect of the feed-back from the rectifiers 12, 13 on the coils 39, 40, 43, 44. The resistances 41, 45 and their shunting condensers 42, 46 reduce the time constant of the feed-back circuit and increase stability. Suggested values of resistance are from two to ten times the coil resistance. Phase advancing to correct for the time lag of the motor is provided by a condenser 38. According to the Provisional Specification, the feed-back ampere turns are less than the ampere turns in the output winding.
