Title: Improvements in or relating to machines for pressing shoe bottoms
IPC: A43D89/00
Filed: 1934-11-19
Abstract: 447,683. Boot-making machines. UNITED SHOE MACHINERY CORPORATION, 140, Federal Street, Boston, U.S.A.-(Assignees of Fredericksen, J. P. ; Wollaston, Massachusetts, U.S.A.) Nov. 19, 1934, No. 33193. Convention date, Dec. 12, 1933. [Class 17 (i)] Levelling.- Relates to machines of the kind described in Specifications 104,728, 236,270, and 269,114, [all in Class 17 (i)], and consists in modifications adapting this type of machine to the compacting of the inseam materials of a welted shoe after weltsewing and inseam trimming. A pair of tapered pressing rolls are provided operating simultaneously on the opposite sides of the shoe bottom, independently mounted for yield both heightwise and laterally to apply to the inseam materials at the end of the toe and along the sides of the shoe bottom pressure directed both heightwise of the shoe and inwardly from the edge. A pair of rolls 72 are carried on ball bearings at the ends of arms 76 pivoted on horizontal pivots 81 to brackets 82, these being pivoted on vertical pivots 84 to a sleeve fixed to a rod 88 mounted to turn in a holder 90 provided with trunnions 92. The rod is secured by a sleeve 94 engaging a recess in the holder, stop screws 98 threaded through lugs on the sleeve allowing adjustment of the rod about its axis. The arms 76 are urged together by a spring 100, a link 102 limiting their outward spread. A second spring 106 is threaded over a rod 108 carrying a pair of plates 112, 122, each with a tubular extension engaging the rod, the plates being urged by the spring against flat faces of members 110 secured to the brackets 82. The construction centralizes the arms 76. The arms are independently urged downwardly by adjustable springs 126 to a limit determined by stops 142. In addition, the holder 90 is urged downwardly by a spring 144 engaging an arm 146 pivoted to the frame and connected to the holder by a link 150. The strength of the spring is adjusted by a handwheel 164 on a rod having threaded engagement with a sleeve 156 held down by an arm of a lever 158 provided with an adjustable stop screw 162. The cam shaft is driven by a worm 44 through a clutch 48 operated by a control rod 50. A path cam 36 is formed to oscillate the jack under the rods one complete traverse from toe to heel and back in half a revolution. Consequently two trip members 52, diametrically opposite, are carried by the cam, and engage a roll 54 on a plate pivoted at 56 to actuate an arm 62 to move the rod 50 to the right to stop the machine. The starting treadle rocks the shaft 50 to free it from the arm 62. The cam shaft also carries a pair of trip members 70 to free the jack from its oscillating mechanism as described in the prior Specifications. A saddle of the kind described in Specification 268,886, [Class 17 (i)], may be interposed between the rolls and the work.

Title: Improvements in or relating to computing arrangements
Inventor: STOKES JOHN ARTHUR
IPC: G06G7/22
Filed: 1955-01-20
Abstract: 791,034. Computing apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 20, 1955, No. 33281/55. Divided out of 791,031. Class 37. Deflections of the stylus in a contouring machine produce voltages proportional to the deflections in the x, y and z planes and the computing arrangement adds the x and y signals vectorially and from the resultant signal produces an A.C. signal of reference phase for addition vectorially to the z signal to produce a final signal proportional to the total stylus deflection. The voltage fed to the transformer Tl primary (Fig. 2) for the x deflection is of reference phase and differential change in the inductances L1, L2 caused by the deflection along the x axis produces a potential difference across the resistance inductance bridge which is amplified by the valve thus producing across the anode load a voltage proportional to the x deflection of the stylus. A similar circuit for the y deflection is fed with a voltage in phase quadrature with the reference voltage so that the outputs from these circuits (X and Y in Fig. 3) is combined vectorially in the circuit H which comprises two series-connected resistors from the junction of which a signal hd is obtained of phase angle #. This signal is then rectified in RF1 to produce a D.C. signal proportional to the vectorial sum of the x and y deflections and the D.C. signal fed to the circuit PR, which may be as shown in Fig. 4, to produce an A.C. signal proportional to hd and of reference phase. The modulator (Fig. 4) comprises two bridge-connected rectifier circuits arranged as shown and fed with bias voltages a<SP>1</SP>1, a<SP>1</SP>2 and b<SP>1</SP>1, b<SP>2</SP>2 in antiphase relationship from the secondary windings of the transformer T4 supplied by a V REF voltage. Thus on every alternate cycle the bridge circuits RB3, RB4 are conductive and the voltages induced in the respective halves of the transformer T5 primary are proportional to the D.C. input but are of opposite polarity to each other. The output from the transformer T5 is therefore an A.C. of reference phase and of mean value proportional to the D.C. input. The circuit Z which is similar to Fig. 2 is fed with a V QUAD voltage and the output is added in C to the hd signal of reference phase so that an A.C. output proportional to the x, y and z deflections is obtained from the junction of its two resistors. This signal may be subsequently rectified in the circuit RF. Specifications 791,032 and 791,033, [both in Group XXXV], are referred to.

Title: Improvements in valve devices for automatic control of temperatures, pressures or the like
IPC: G05D23/275
Filed: 1927-12-13
Abstract: 282,394. Holmen, H. L. Dec. 16, 1926, [Convention date]. Electrically-actuated valves. - An electromagnetically-operated rotary sliding valve for controlling the supply of a fluid heating medium in connection with automatic control of temperature, pressure, or the like, as for example in pasteurizine apparatus, comprises a narrow segment of a surface of rotation extending in the direction of the axis whereby the range of movement and the area of frictional contact surface are minimized so that the amount of electric energy required for the operation is small. For this purpose, the valve 36, Figs. 1 and 3, comprises a cylindrical segment operating in conjunction with a rectangular supply opening 37. The valve is adjustably mounted on the operating spindle 1 by means of a slot 35, as shown, and a flattened portion 33 on the spindle, a strip spring 40 pressing the valve member radially and yieldingly in contact with its seating. The valve member is also formed at the top and bottom with curved guiding arms 39 forming extensions of the closing surface. As applied to a thermostat, when the temperature in the apparatus falls the pointer arm 20, Fig. 1, of a thermally-responsive device closes the contacts 22, 23 whereby current from a local battery 24 causes an electromagnet 19 to close contacts 18 whereby current from a main supply 14 passes through the windings of an electromagnet 6 by way of switch contacts 16 on a swinging switch connected to the valve. The armature 5 mounted on the valve shaft 1 is drawn down and the valve opened to give an increased supply of the heating medium. At the same time a ratchet 7 on the valve shaft snaps past a spring-urged pawl 9 and holds the valve in the opened position. Should the temperature now rise unduly the thermal device 20 closes the contacts 22', 23<1>, and current energizes electromagnet 19<1>, thereby closing contacts 18<1> and giving supply to an electromagnet 13 through contacts 16'; the catch pawl 9 is consequently withdrawn and allows the spring 25 to close the valve. This action furthermore re-sets the contacts at 16, as shown, in readiness for the succeeding opening operation of the valve.

Abstract: 1,121,201. Fourier integral computing. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. 27 July, 1966 [27 July, 1965], No. 33841/66. Heading G4G. [Also in Division G1] In a device for computing the Fourier integral transform of the interferogram of the spectrum of an unknown source A, the spectrum of a known white light source B produced by an interferometer 16 and a spectrograph 2, is received by a multi-cellular receiver device 4 (apparently photoelectric) which emits signals analogous to functions Cos (2#N i u), where N i  denotes the different wavelengths of the white light and u is the path difference of the interferometer, these analogue signals being then multiplied by the signals analogous to interferogram H(v) of the unknown source, where v is the path difference of an interferometer la receiving light from that source. The resulting product signals are then integrated in an integrator 6 to give analogue signals of the required Fourier integral transform. The two interferometers may be combined as one (Fig. 2, not shown) and the receiving device may be of one of three forms. In the first form an optical filter is placed between the spectograph 2 and the interometer 16, and the receiver 4 comprises an integrating plate, e.g. a photographic plate, the sensitive layer of an electronic camera or the mosaic of an electronic integrator receiver. In the latter form the receiver is of the type in which exchange pattern on a photoconductive or photosensitive surface is scanned by an electron beam and (Fig. 3, not shown) a retractable mirror 12 is provided for producing outputs Cos<SP>2</SP> (#N i u) and Sin<SP>2</SP> (#N i u) from this receiver. The two outputs are later combined in integrator 6 to produce the signals analogous to function Cos (2#N i u).
