Title: Hat-brim ironing machine
IPC: A42C1/08
Filed: 1925-06-10
Abstract: 238,193. Reynolds, R. K. Aug. 7, 1924, [Convention date]. Ironing.-In a machine for ironing hat brims, a heated iron is oscillated along the brim while this rests on a heated support itself reciprocated substantially parallel to the path of the iron. The hat is fitted on a block on an intermittently rotated shaft which is automatically tipped and raised and lowered to compensate for the irregular shape of the inner edge of the brim. The machine is provided with fast and loose pulleys 34 on a worm shaft 33 driving a vertical shaft 37. A crank 40, Fig. 1, on this shaft oscillates an iron-holder 20 sliding in curved guides 27, 28. The iron 17 Fig. 2, suitably heated by gas or electricity, is pivoted at 29 to a plunger 19 pressed towards the hat crown by a spring 21. Below the iron is a heated support 13 reciprocated on rollers 11<a>, 11<b> by an eccentric strap 44, Fig. 1, on the shaft 37. Preferably the iron and support move in opposite directions. The hat block 53, Fig. 5, is secured on a shaft 62 by a catch 59. This shaft is intermittently rotated by a pawl co-operating with an oval ratchet 78, Fig. 4, the pawl being connected bv links and levers to a further eccentric on the shaft 37. On the shaft 62 is fixed a crosspiece 64 restrained at its ends by slots in members 66 rotating with the cross-piece in a circular casing 63. The lower end of the shaft 62 is provided with a crank pin 80 engaging a heartshaped cam-groove 81. Tilting of the shaft by the crank pin in conjunction with the raising and lowering of the shaft by leverage about the ends of the member 64 compensates for the difference between the major and minor axes of the hat and the difference in elevation of the inner edge of the brim at the sides and at the front and rear of the hat. The iron comprises a flat operating surface 17<c>, Fig. 7, with upwardly sloping ends.

Title: Artificial chocolate flavor base for confectionery products and method of producing the same
Inventor: RUSOFF IRVING ISADORE
IPC: A23L27/28
Filed: 1958-05-12
Abstract: An artificial, chocolate-flavour base for confectionery products comprises the reaction product of a protein hydrolyzed to an extent of 8% to 70% of complete hydrolysis with a reducing saccharide at a temperature of 90 DEG -170 DEG C. and for a time sufficient to produce the flavour base in a substantially anhydrous condition.  The saccharide is usually reacted in a preparation of 5% to 150% by weight of the protein hydrolyzate. Enzymatic, acidic, or alkaline techniques may be used to effect the hydrolysis of the protein. Reducing saccharides include xylose, arabinose, rhamnose, glucose, galactose, mannose, levulose, sarbose, lactose, maltose, manninotriose, and precursors such as sucrose, dextrin, and raffinose.  Specified materials from which the protein hydrolyzate may be obtained are wheat, maize, hemp, soy, rye, oats, peanut, or barley, milk protein, egg albumin, serum albumin, fish albumin, gelatin, elastin, collagen, and keratin.  Suitable reaction temperatures are 90 DEG -130 DEG C. when the reducing saccharide is a pentose, 120 DEG -150 DEG C. for a hexose or polysaccharide, and 140 DEG -170 DEG C. when a non-reducing saccharide which is a precursor of a reducing saccharide is employed.  The artificial chocolate flavour base may be used in combination with bitterness, astringency and other flavour factors to provide an imitation chocolate flavour, or to enhance the flavour of natural chocolate products.  An enhanced flavour is obtained when the reaction is carried out in a presence of an amino acid, of which a number are referred to.  According to an example (Example 12), reconstituted skim milk of 20% solids content was hydrolyzed at about 46 DEG C. for 20 minutes using trypsin at a level of 0,6% by weight of the total milk solids; the treated skim milk solution was then fed in to the trough formed by a pair of steam-heated drying rolls operating under conditions specified in the example, and the resulting reaction product, which was a light brown friable material of less than 5% moisture content, when removed from the rolls had a temperature of about 95 DEG C.  In another example (Example 20), an artificial chocolate flavour for use in a coating or a chocolate bar was prepared by blending 0,5-5,0 parts of the flavour base of the above-described example, 40-45 parts sucrose, 15-20 parts toasted cottonseed flour as a filler and colouring agent, 0,1-0,6 part a -glucose penta-acetate or 0,03-0,2 part b -glucose penta-acetate for bitterness, 0,5-3,0 parts catechu gum for astringency and 30-40 parts cocoa butter together with minor proportions of other flavouring agents such as vanillin, ethyl vanillin, and sodium chloride.  In other examples, the flavour base of the example first described above was employed to prepare a milk drink (Example 21), a chocolate flavoured fudge (Example 22) and a chocolate flavoured frozen sherbet (Example 23).

Abstract: 914,837. Semi-conductor devices; potentiometric voltage measurement. WESTING- HOUSE ELECTRIC CORPORATION. April 27, 1961 [May 2, 1960], No. 15341/61. Class 37. A semi-conductor device for use as a variable resistor comprises a body, Fig. 1, of semiconductor material, e.g. Si, having a base region 10, on one face 11 of which an emitter region 14 is formed and on the other face 12 of which a collector portion is formed, comprising a plurality of collector regions 16 ... 19, ohmic electrodes 21, 22 on the base region 10 being connected in operation to a source 24 of control potential to apply an electric field transverse to minority carrier paths between the emitter and the collector regions; the carriers are deflected in accordance with the magnitude and sense of the said field and the output at an electrode 20 connected to one collector region 19 is determined by the resistance path taken by the carriers due to such deflection. The resistance between collector regions 16 ... 19 may be reduced by coating the face 12 with conductive material 26 such as Ag, Au, Sn, which may be insulated from the base 10; this resistance may be increased by etching slots in the base 10 between the collector regions; further variation may be achieved by illuminating the path 16 ... 19 by a controlled light source such as an electro-luminescent cell. A single collector portion may be formed on the face 12 and subsequently separated into regions by etching slots which may or may not extend through the collector junction. To enable a unipolar control potential to be used, the emitter 14 may be located opposite one end collector region 16, as shown in Fig. 4, which illustrates the device used as a voltage divider, the applied voltage being supplied between emitter 14 and collector region 16 and the output being taken off between collector regions 16 and 19. For use as a potentiometer, a known D.C. is connected between 14 and 16, and the unknown potential in series with a galvanometer is connected between 16 and 19, the amount of control potential applied between 21 and 22 to achieve zero indication on the galvanometer being measured. The body may have emitter and collector regions formed by alloying or vapour diffusion ; impurities mentioned are B, Ga, Al and As, Sb, P ; where alloying is used the impurity may be mixed with a neutral material e.g. Au or Pb. The device may be used as a multiplier or a function generator. Specifications 906,765 and 913,674. are referred to.

Title: Improvements in or relating to method and means for adjusting the outlet cross-section area of the exhaust nozzle of a jet propulsion plant for aircraft and the like high speed vehicles
IPC: F02K1/15
Filed: 1946-05-21
Abstract: 618,781. Liquid-pressure servomotor-control systems. SOC. RATEAU, and ANXIONNAZ, R. May 21, 1946, No. 15351. [Class 135] [Also in Group XXVI] Relates to jet-propulsion plant for aircraft comprising a centrifugal or axial-flow compressor, a prime mover driving the compressor, means for heating the compressed air and a propulsion jet of variable cross-sectional area and consists in means for varying the jet area so as to maintain the value H/Q2 constant, where H is the compression head and Q the quantity delivered by the compressor. The means may be responsive to variations, from a standard direction, of the direction of the absolute velocity of the air leaving the running blades of the compressor. Or, the means may be responsive to variations in the value pc-pa/pa-pb, where pa is the total head and pb the static head of the air entering the compressor and pc is the total head of the air leaving the compressor. Alternatively, pc in this value may be the static head of the air leaving the compressor. When fuel is burnt in the turbine exhaust in front of the propulsion jet, an additional adjustment of the jet area is necessary. This adjustment is effected by q means responsive to the value -, where q is p the rate of supplying fuel and p the intake pressure of the compressor; the final adjustment being effected by the means responsive to variations in the value pc-pa/pa-pb. Variations in the direction of the absolute velocity of the air leaving the compressor may be detected by a pivoted vane, movement of the vane being used to control a servomotor operating tha jet obturator. Or the variations may be detected by differences between the static pressures on the two sides of a device fixed in the air stream, these pressure differences being used to control the servomotor. In the device shown in Fig. 5, the dynamic head a and the static pressure b from a pivot tube in the compressor inlet are applied to opposite sides of a diaphragm 21. The dynamic head a and the dynamic head c obtained in the compressor delivery are applied to opposite sides of a second diaphragm 20. The diaphragms are connected in opposition to a lever 22, movement of which controls the jet obturator 7. A cam may be inserted in the connection between the lever 22 and the servomotor valve 9 to procure the correct displacement of the obturator. Fig. 9 shows this device combined with means responsive to variations in the value q/p, the movements being combined by a floating lever 40 and the resulting movement being modified by a cam 25 acting on a bell-crank lever 42. The pressure pot 26 responsive to the pressure q and its point of application 30 to the lever 28 are moved bodily by a pressure pot 32 responsive to the pressure p of the compressor inlet.

Filed: 1970-04-01
Abstract: 1311182 Milling machine HEXCEL CORP 1 April 1970 [1 April 1969] 15495/70 Heading B3K A milling machine for cutting an airfoil surface 59, Fig. 2, comprises a rotary cutter 56 pivotally mounted in a head 52, the latter being movable along guide rails 46 by a chain drive 54, positioning means 60 defining the angular position of cutter 56 during each longitudinal movement along the surface 59, and means responsive to means 60 for continuously adjusting the angular position of the cutter during each reciprocating movement. Rails 46 are mounted in a frame 26, having wheels 31, 32, supported on cam tracks 34, and between each pass of the cutter along the surface 59, the frame, along with the cutter is moved in incremental steps along the cam tracks. Tracks 34 are arcuate and the radii of the tracks are struck from a point 44, which is also the point at which the airfoil cam surfaces converge. Positioning means 60 comprises a tilt beam 62, pivotally connected to a pair of followers 64, which co-operate with cams 68, and an arm 70 extending from head 52, which carries a potentiometer operated by a gear 72, actuated by a rack 74. Beam 62 is set at an angle determined by the shape of cams 68 at each incremental step Fig. 3, and as head 52 moves along rails 46, rack 74 moves vertically, so that electric signals from the potentiometer are employed to constantly adjust the angular position of the tool axis. The cutting face of the tool Fig. 1 is therefore always tangential to the airfoil surface, and the required angle may vary along the length of the surface, and also at each incremental step. The means for adjusting the tool includes potentiometers (82), (92), Fig. 5 (not shown), a differential amplifier (84), an electrohydraulic servo valve (86), and an hydraulic cylinder (88). In a modification, beam 62, arm 70, gears 77, 74, and roller 76 of positioning means 60 are replaced by electrical positioning means (94), Fig. 6 (not shown). Head 52 has guide blocks 130, Fig. 7, which are slidably mounted on rails 46, and milling head 138 has rollers 140 which engage arcuate tracks 132, so that the milling head and its cutter can be pivoted to the required angle by an hydraulic, actuator 150 actuated by hydraulic cylinder (88) Fig. 5 (not shown).
