Title: Improvements in or relating to method and apparatus for combined stretch and die forming metal stock
IPC: B21D25/02
Filed: 1960-11-18
Abstract: 959,094. Stretch forming. CYRIL BATH CO. Nov. 18, 1960 [March 17, 1960], No. 45984/63. Divided out of 959,093. Headings B3E and B3Q. A method of cold forming sheet metal stock into an article, e.g. automobile panels between complementary drawing dies having article forming surfaces which are co-extensive peripherally and which are curvilinear in both longitudinal and transverse cross-section comprises gripping only one pair of opposite margins of the stock and moving them away from each other as well as effecting relative movement between one of the dies and the stock in a direction transverse to the plane of the stock to stretch form the stock over this die and thereby effect partial conformation of the stock to the surface of this die, and then completing conformation of the stock to this die surface by closing the dies to engage the other face of the stock with the other one of the dies. Apparatus for carrying out the method is fully described in Specification 959,093.

Abstract: 1,206,112. Electric motors. NATIONAL RESEARCH DEVELOPMENT CORP. 6 Oct., 1967 [20 Oct.; 1966], No. 47094/66. Heading H2A. A reluctance rotor has no more flux-barriers than the stator has pole-pairs, and these fluxbarriers extend in a substantially parallel array diametrically across the rotor but do not reach the circumference. Thus, for example, the three flux-barriers 6, 7, 8 provide a rotor suitable for 6-pole operation. Squirrel-cage bars 2 are provided. For pole-changing motors, the number of flux-barriers is made appropriate to the sum of the two pole-numbers. Thus, for 6 and 8 poles, seven barriers are used. But if one pole number is a multiple of the other, fluxbarriers for the higher number only are provided. Any number of pole-numbers may be accommodated. The outer pairs of barriers may be replaced by surface grooves (Fig. 8, not shown).

Abstract: 1,064,500. Controlling tractors. MASSEYFERGUSON-PERKINS Ltd. Nov. 17, 1964 [Nov. 30, 1963], No. 47353/63. Heading B7H. The lever 15 controlling the power lift mechanism of a tractor also, over that portion 16A of its travel corresponding to the operational position of the implement, actuates the tractor differential lock mechanism. The latter is actuated through a shaft 13A, crank 25 and a piston 27, which is normally held in the inoperative position by fluid pressure from the tractor main pump through lines 19 and 34. A valve spool 31B is normally held in the inoperative position, in which line 37 is connected to exhaust line 21, by a spring 41 and is moved into an operational position, determined by a stop 41A abutting the valve casing, by movement of the lever 15 into the range 16A, the lever 15 acting through a flexible cable 43 and spring 44. In the latter position of spool 31B, both sides of piston 27 are subjected to pressure, whereby, because of the greater area on one side, the piston 27 is moved whereby the differential lock is applied. The normal pedal for controlling the differential lock is attached to the shaft 13A and affords a visual indication of the position of the lock.

Title: Improvements in or relating to methods of treating glass in sheet form
IPC: C03B27/056
Filed: 1962-12-28
Abstract: <PICT:1073914/C1/1> In a method of heating glass in sheet form (e.g. in a tempering process) glass sheets are conveyed edgewise through an enclosure and supported as they are advanced in a plane intersecting the plane of the conveyer by <PICT:1073914/C1/2> maintaining a succession of spaced-apart narrow cushions of heated air against the glass, by releasing heated air under pressure into the cushions and simultaneously directing heat at the glass where it is exposed between the cushions, said cushions extending across the height dimension of the glass, and the heated air leaving the narrow cushions in a generally downwards direction.  A glass sheet 7 is supported upon rollers 5 and fed by rollers 8, 9 into a heating zone 2 of a tempering apparatus. The heating zone comprises a series of pairs of opposed gas boxes 10 having perforations through which gas under pressure can percolate.  The gas pressure within the boxes is 3 to 10 inches w.g. and is such as to maintain a gas pressure of 0.5 to 2 i.w.g. between a glass sheet in the zone and the boxes.  This pressure is sufficient to balance the sheet with a clearance of 0.040 inch from the faces of the boxes. To heat the glass sheet the gas cushions thus formed are fed with preheated gas which may be air or carbon dioxide at the temperature to which the sheet is to be heated, radiant heaters 11 aiding the process.  After heating the sheet, supported only upon its lower edge and by the gas cushions, passes into the quenching zone 3 where cold gas is fed into the cushions from boxes 10 and cold gas is also directed against the sheet from quenching boxes 12 at a pressure of about 5 i.w.g.  The sheet is then conveyed away.  In an alternative embodiment the conveyer rollers 5 are at an angle of greater than 10 degrees to the horizontal, e.g. 45 degrees and the edge of the sheet 7 is held within a recessed portion 14 of the rollers 5 the sheet also being supported by gas cushions acting against at least one of its major faces.

Title: The production of paper-like structures from flexifilament sheets
Inventor: ROSENBLATT NAFTALI WALTER
IPC: D04H1/54
Filed: 1963-08-30
Abstract: A printable, paperlike structure is made from a sheet of flexifilaments of high-density crystalline polyethylene by permeating it with saturated steam while it is disposed between two generally parallel forming surfaces.  At least one of these surfaces is porous and flexible, and they are pressed together sufficiently to restrain lateral shrinkage of the sheet and to prevent reduction of the birefringence of the film fibrils of the flexifilaments by more than 50%.  The temperature of the saturated steam on the two sides of the sheet must differ by less than 5 DEG C. and be less than the melting point of the polyethylene but within 20 DEG C. thereof.  Frictional contact of the forming surfaces with the sheet is maintained while cooling the sheet to below the temperature of the steam.  The sheet may be made by the method of Specification 970,070.

Filed: 1975-12-05
Abstract: 1522997 Transistor amplifier SONY CORP 5 Dec 1975 [13 Dec 1974] 50028/75 Heading H3T To bias the bases of amplifying transistors Q 1 , Q 3 , ensuring equal temperature stabilized D.C. collector currents, bias transistor Q 4  supplies the base of Q 1  from its emitter and the base of Q 3  from a tap in the emitter load, the lower half of which may comprise in addition to resistor 11 a transistor Q 7  with base resistively strapped to its collector, while the base of Q 4  is tapped off a chain across the supply comprising two resistors 12,14 separated by one diode connected transistor Q 6  and one transistor Q 5  with base resistively strapped to its collector. To equalize the D.C. collector currents of Q 1 , Q 3 , assuming the h @  of all transistors, preferably integrated, is the same although liable to vary, the resistors should be related by: where K 1 , K are constants. Then collector currents I c1  = I c3  = KI c5  = (K/K 1 )I c7 . The circuit of Fig. 4 applies if R 1  > R 7 , when the gain of the Q 1  stage is lower than that of the Q 3  stage: if R 1  <R 7  the tapping positions of the Q 1 , Q 3  bias lines are reversed (Fig. 6, not shown). Transistor Q 7  may be omitted (Figs. 3 and 5, not shown) in which case: Then I c1  I c3  = KI c5 . The value of the D.C. I c5  which sets the common values of the currents I c1 , I c3  depends on V BE , the base emitter potential drop assumed uniform for all transistors, making the system somewhat temperature sensitive. The impedance seen looking into the emitter of Q 4  may be made small enough to prevent A.C. signal feedback from Q 3  to Q 1  via the bias lines, eliminating the need for a decoupling capacitor as in the prior art (Fig. 2, not shown).
