Title: Improvements in and relating to dividers for dividing dough into portions suitable for loaves of bread
IPC: A21C5/04
Filed: 1920-10-05
Abstract: 172,467. Sharpe, F. H. Oct. 5, 1920. Cylinder machines.-In a machine in which dough is fed into radial pockets formed in a rotary dividing- member 2, and provided with movable bottoms 7, the latter are positively moved from their outer position a to their inner position d so as to assist the filling of the pockets by suction. For this purpose, each pocket bottom is provided with two arms 11 which are controlled by rollers 13 moving between cam-surfaces 16, 18, Fig. 4, and are held in position by spring-actuated friction plugs 30. In order to vary the capacity of the pockets, the position of the surface 18 is adjusted by moving the cam 19 in the guiding-grooves 21, 23 by means of the finger 26. A wiper roll 10 holds the dough in the pockets while a scraper 8 having a cutting-edge 9 divides it from the remainder in the receiver. The dough is fed into the side 33 of the receiver bv rolls 35, 36, 37 so that the material is kept under gentle pressure. In order to divide the dough into smaller portions, the pockets may be provided with transverse knife elements corresponding with slots in the bottoms 7.

Title: Improvements in hydraulic pipe-testing devices
IPC: G01M3/28
Filed: 1925-11-11
Abstract: 250,486. Zore, A. Nov. 11, 1925. Testing strength of pipes.-Relates to apparatus of the kind provided with a hydraulicallyoperated differential piston device and consists in the employment of two differential pistons one of which operates a clamping device for holding the pipe during the test, means being provided for setting the pipe in communication first with the water supply and then with the pressure chamber of the second piston. Two cylinders Z<1>, Z<2> are connected by a neck Z. A differential piston 11, 11<a> works in the cylinder Z' and neck Z forming pressure chambers C, D. In the cylinder Z' works a hollow piston 1<a> having a hollow stem in which the hollow stem of a padded buffer 2 is adapted to slide. A spring-pressed valve 3 is fitted in the piston 1<a> as shown. This piston forms pressure chambers B, A. Pipes 24, 25, 26 lead from a piston valve chamber 20 to the pressure chambers A, B, C. The valve cylinder 20 also connects with supply and exhaust pipes 27, 28 of which the pipe 27 is in communication by a pipe 29 with the chamber B. The latter communicates with the chamber D through a passage 20 in which is a spring valve 6. A manometer 10 and safety valve 8 are connected to the passage 30. In use, one end of the pipe to be tested is applied to the pad 31 and the other held for application of the pad 2. The valve 21 is then moved to the position shown in Fig. 1, so as to place the chamber B in communication with supply. The piston 1<a> is moved to the left, notwithstanding the fact that the chamber A is also open to supply, until the pad 2 abuts against the pipe. The valve 3 is then opened on slight further movement of the piston and pressure fluid is admitted to the pipe, air escaping through the bore in the pad 31 and the chamber 23, until a hole in the chamber is closed on the float 34 rising. The valve 21 is then moved to the position shown in Fig. 4, when chamber C is placed under pressure and the piston 11, 11<a> forced to the left, the non-return valve 5 closing and the valve 6 opening to intensify the pressure in the pipe. When the gauge 10 indicates a sufficiently high pressure, the valve 21 is again moved to place the chamber C to exhaust. The valve 6 closes and the pipe may be examined while under pressure. The piston valve is finally moved to place chambers H. C to. exhaust. To prevent thin pipes from bending and cutting into the pads, the pressure may be regulated. For this purpose the pressure spaces at both sides of the clamping piston 1<a> are connected to cylinders 12<a>, 13<a>, the piston 12 being acted upon by a spring 18 while the piston 13, by means of a roller 19, rests on a lever 15 connected to the rod 14. The piston 12a when moved under the pressure in the chamber B acts on the piston 13<a> and the leverage can be varied. A valve 36 enables the chamber A to be relieved into the atmosphere.

Title: Improvements relating to two-way amplifiers for telephone and like circuits
IPC: H04B3/16
Filed: 1929-09-19
Abstract: 319,287. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). Sept. 19, 1928, [Convention date]. Two-way repeating systems.-Two-way amplification is obtained, with or without frequency discrimination, with simplified circuits, by the use of negative resistances as members of an impedance network which is matched to the impedances of the lines served by it. The negative resistances may be provided by thermionic valve circuits. Fig. 5 shows a two-section N network, terminated mid-shunt, containing negative resistances W, W1, and having series impedances Lo, Co, Ro, distributed between the upper and .lower legs of the circuit, the inductances Lo being linked as shown. In a modification (Fig. 10, not shown) the series impedances are arranged in one leg only of the circuit. In the arrangement shown in Fig. 9 the series and shunt elements ,comprise networks differing in magnitude but similar in form, except that R1 is a positive resistance while W, W, are negative. In another arrangement (Fig. 8, not shown) the shunt elements each comprise a negative resistance alone, and the resistance R1, Fig. 9, then becomes negative.

Title: Improvements in or relating to presses, for example baling presses
IPC: B30B9/30
Filed: 1934-10-05
Abstract: 445,294. Toggle linkages. WOOLSTENCROFT, G., Rose Lynn, Cotton, Holmes Chapel, Cheshire. Oct. 5, 1934, No. 28512. [Class 80 (iii)] [See also Groups V, XXVI, and XXIX] In a baling or like press in which the platen c, Fig. 1, is traversed by toggle mechanism, the toggle links e, f are connected to the platen and a fixed abutment and are coupled at a distance from their other ends by a pivot pin g movable in a slot in the cross-head k connected to the ram l of the steam, hydraulic, mechanical, or manual power applying device. When the links are closed, as shown in Fig. 2, the initial movement of the cross-head causes inclined surfaces i to engage rollers e<2>, f<2> on outwardly turned projections of the links e, f. The links are opened rapidly while the pin g moves in the slot in the cross-head, and thereafter the cross-head acts directly on the pin. In a modification, the extension of the link e, Fig. 9, is engaged by the cross-head k, while a cam-lever q pivoted to the cross-head is adapted to act on the roller f<2> of the extension of the link f when the pin g is moving in the slot in the cross-head k. In the arrangement shown in Fig. 1, an oscillating fluid-pressure cylinder m has a gland for the ram l, so that, on the working stroke, air is compressed in front of the piston and serves, in conjunction with a counterweight q, to withdraw the platen after the working pressure has been removed.

A magnetic head for reading information from a magnetic record and capable of re-writing the information with a small delay comprises two separate cores closely spaced along the path of a record medium and each comprising a pair of legs, the inner surfaces of the legs of each core diverging away from their transducing gaps and the inner surfaces of adjacent legs of the two cores inclining away from each other away from the gaps. Fig. 1 shows a pair of transducer stages 1 and 2 in a common mounting 24 and arranged so that information recorded by stage 2 can be read back by stage 1 with a minimum of delay, i.e. the spacing is as close as possible and cross-talk is minimized by magnetic shielding and by the wedge 'shape of the transducer gaps 5 and 5a. The two stages are identical, and stage 2 comprises a yoke 3 carrying a coil 8 and associated across gaps 5 and 7 with a bar 11 which is silver plated on three sides of the portion parallel to the coil portion of yoke 3. Gap 5 contains a silver wedge-shaped shim 6. The stage is secured to a mounting block 14 attached to an extension 15 of frame member 23, and its spacing relative to stage 1 can be adjusted by screw member 17. Magnetic shields 16, 16a surround the two stages and can be adjusted by a rod 21 which can be secured by a grub screw 22. The outer limbs of the two cores may be provided with protruding stops extending along the record path for a length corresponding to half a bit.
Patent GB-674054-A (GB)
Title: Improvements in or relating to a magnetic impulse record member
IPC: C09D5/23
Filed: 1948-11-03
Abstract: A magnet impulse record member comprises a non-magnetic base to which is secured a binder containing powdered Fe3O4 or gamma Fe2O3 having a particle size less than 6 microns in maximum dimension and a coercive force (Hc) of at least 200 oersteds.  The material may be crystals of Fe2O3 of Fe3O4 or mixed crystals of both of acicular form.  To make the record member a tape of non-magnetic material such as cellulose acetate may be coated or impregnated with the magnetic material and then calendered. Acicular crystals of Fe2O3.H2O are first obtained, e.g. by dissolving NaOH and FeSO47H2O together in water, collecting the deposit of Fe2O3 .H2O and heating this with FeSO4.7H2O and scrap-iron in water.  The dried filtrate which comprises the acicular crystals is heated at between 500 DEG F. and 1000 DEG F., e.g. 750 DEG F., under a stream of hydrogen with or without an admixture of water vapour, and gives acicular mixed crystals of Fe3O4 and Fe2O3 (in proportions, e.g. of 78.7 per cent and 19.3 per cent).  By varying the time allowed these crystals grow to different sizes and have different magnetic properties.  Before the reducing process, the acicular crystals of Fe2O3.H2O can be heated in air at between 500 DEG F. and 1550 DEG F. to remove the water of hydration.  The mixed Fe3O4 and Fe2O3 may be heated in air at between 300 DEG F. and 900 DEG F., examples being given of 450 DEG F. for about 10 hours, 550 DEG F and 700 DEG F.  In the reduction process the hydrogen may be replaced by CO, sulphur, sodium acetate, or pyrogallol.  The product may be reoxidized and reduced several times.  Desirable magnetic properties of the product are coercive force between 200 and 350 oersteds, maximum induction: remanence not greater than 3:1, and remanence at least 80 per cent of maximum induction, when the field amplitude (H) is 1000 oersteds.  Also the remanence should not exceed 20 per cent of the maximum induction when field amplitude is less than 250 oersteds, and the remanence/field curve should not rise appreciably until the field (H) reaches 250 oersteds to reduce the effect of stray fields.

Title: Improvements in or relating to sheet materials
IPC: B32B27/00
Filed: 1936-10-21
Abstract: Flexible sheets of cellulose acetate or other cellulose ester or ether are pleated and the pleats then flattened over a part or parts of the pleated area of the sheets, to give a material suitable for ornamenting generally, and in particular for use in lampshades, as coverings for flower pots, hoods for flowers, hat bands, brims, bracelets, eyeshades, curtains, garters, belts, receptacles and wrappers, ribbons, collars, holders, and tabs. The flattening may be in the form of patterns of different styles. Further effects may be obtained by completely ironing out the pleats over selected areas on which the pleats have not been flattened, in some cases the ironing-out may produce an attractive crinkling of the material. Flattening may be carried out while the material is in a softened condition as produced by heat, and conveniently in a press or by passage through embossing rollers. The pleating may be effected similarly while the sheets are softened by solvents, or by heat as by passage through a heated chamber, or by hot water or steam, and the pleating members are preferably heated; after pleating the material is cooled while tightly held in the pleated condition.  The sheets preferably contain plasticizers, and they may also include effect materials such as pigments, dyes, fibres and other filling materials, and also fire retardants, waterproofing agents &c., the effect materials being incorporated in the body of the sheets or applied to the sheets after their formation.  Two or more sheets may be superimposed, the pleats of the several sheets being arranged parallel to one another or at an angle; and the sheet material may be laminated with paper, silk or other fabrics, or cellulosic sheet material, in particular with a film having an embossed cr<\>zepe or other design, the lamination being carried out before the sheets are pleated.  The pleated and flattened sheet material may be cemented to a suitable backing.  An edging of paper, metal foil, fabric or transparent cellulosic material may be embodied in the sheets.  The sheets may be lacquered, varnished or coloured either all over or in designs.  Specification 308,659, [Class 121], is referred to.

Abstract: 190,096. Illingworth, W. H. Sept. 26, 1921. Mercury cut-outs in which a column of mercury a', a, a<2> makes an electrical connection between terminals F, F' which is broken when the current exceeds a certain amperage, are characterized by the fact that expansion or breakage of the column imparts upward movement to a member D which is completed by the action of spring-actuated levers d<11>. The expansion of the mercury column is effected by restricting it at a and the further movement of the member D by providing it with a cap d<2> having inclined surfaces. In a modification the movement of the levers d" also withdraws latches d<12> pivoted to them from a shoulder on the cap F', whereupon the cap F<1> is pressed down by a spring and forms a chamber into which all the mercury is withdrawn. The movement is limited by links f<7> fastened to the cap F' and having a cross-head f<6> which simultaneously presses down the member D into its original position. The cut-out is re-set by pressing up the cap F'. Specifications 121,305, 138,439, 159,917, 166,286, 172,446 and 189,284 are referred to.

Title: Improvements in and relating to electrical indicating recording and regulating apparatus
IPC: H05B1/02
Filed: 1926-11-15
Abstract: 274,692. Apthorpe, W. H., and Cambridge Instrument Co., Ltd. Nov. 15, 1926. Regulation, automatic.-In an electric regulating and measuring instrument in which a galvanometer with a torsion head is employed, means are provided which tend to restore the quantity under examination to a predetermined value in proportion to the galvanometer deflection and at the same time impart a torque to the torsion head which tends to return the galvanometer needle to its zero position. The invention is shown applied to the regulation of an electric furnace in which the moving coil 1 of a galvanometer having a torsion head 17 is connected to a thermocouple_ (not shown) influenced by the temperature of the furnace. The needle 2 of the galvanometer carries at its outer end a rectangular block 3 which is periodically lifted vertically by the front member 24 of a frame 20. In its zero position the block 3 just passes between the horizontal arms 4, 5 of two bell-crank levers pivoted at 6, 7 and carrying pawls 8, 9 at the lower ends of their vertical arms. On deflection of the pointer 2, the block 3, when lifted, lifts one of the arms 4, 5 proportionally to. its deflection, owing to the upper edge of the member 24 being shaped as shown. Rotation is thereby imparted to a ratchet-wheel 12 on a shaft 13 in such a direction as to tend to restore the needle 2 to zero by rotation of the torsion head 17 and at the same time, by means of the rheostat 18, to effect the required control of the furnace, current either directly or through relay apparatus. The frame 20 is rocked by means of a cam 22 on a shaft 23 which is rocked by the alternate action on a plunger 42 of a solenoid 36 and a spring 28, the motion being damped by means of a bellows 43 communicating with the atmosphere through a small hole 44. The shaft 23 carries arms 31, 32 which cause a blade 33, controlled by a spring 38, alternately to rest against a back stop 37 and a contact screw 35, in which latter position the circuit of the solenoid 36 is completed. Other means of rocking the shaft 23 may be employed. Specification 8518/01, [Class 37, Electricity, Measuring &c.], is referred to.
