IPC: B65H45/18
Filed: 1916-07-25
Abstract: 106,186. Whittaker, H. M. July 25, 1916. Folding.-A machine for folding treasury notes, bank notes, bills, and other paper sheets comprises a table A on which the sheet is placed against register stops B, B<1> and is folded by a pair of parallel blades D through an opening C in the table into a receiver or gate L of W-section. Between the blades D is a brake block H supported yieldingly by rods I and springs K on the arm E carrying the blades D. This block nips the centre fold line and holds it while the blades fold the two lateral wings of the sheet down into the gate in zig-zag form. The arm E is on a vertical slide e moved downwards by a cam F on the shaft G and raised by springs G<1>. The gate L is in two parts each on a pivot N so that they may swing, as shown by dotted lines in Fig. 2, when the vertical blade m is moved forward to fold the sheet at right-angles out of the gate through rollers R, whence it passes into a trough T. The blade m is on a slide M moved forward by a cam S and returned by a spring M'. A cam-operated slide Y pushes the sheet along the trough T against a weight W and past retaining catches V. A fixed bracket E<1> above the arm E guides the rods I. The gates L are oscillated by rods Q, connecting them to the pusher slide M, and springs P.

Title: Improvements relating to high tension generating circuits for cathode ray tubes
IPC: H04N3/185
Filed: 1959-03-31
Abstract: 915,516. Automatic regulation. TELEFUNKEN G.m.b.H. March 31, 1959 [March 28, 1958], No. 10758/59. Class 38 (4). The E.H.T. voltage applied to a cathode-ray tube from a line flyback voltage generator is stabilized by varying the bias on the line output amplifier valve in accordance with beam current. The line output valve 6 is autotransformer coupled to the scanning coils 2 and booster diode 4, and to the E.H.T. rectifier 9. The two sections of the auto-transformer are isolated as far as direct-current is concerned by a capacitor 17. A triode 13 connected by a capacitor between the scanning coil circuit and earth, conducts during the fly-back periods to provide a negative voltage across a potentiometer 15. A portion of this voltage is applied as bias to the line output valve 6. The magnitude of this bias is controlled by a potential divider 11, 12 included in series with the E.H.T. negative return line. The voltage drop across this divider depends upon the magnitude of the current which charges the E.H.T. reservoir capacitor (not shown), which in turn depends upon the magnitude of the beam current passed during the previous line scan.

Title: Improvements in or relating to methods for the preparation of organic metal salts
IPC: C07C51/41
Filed: 1954-04-13
Abstract: Organic metal salts are prepared by reaction between an inorganic metallic base and a saponifiable or neutralizable organic material, the process comprising subjecting the reactants to a rate of shear of at least 50,000 reciprocal seconds.  The process is applicable to the neutralization of alkyl phenol sulphides, fatty acids having at least 12 carbon atoms in the molecule and sulphonic acids and to the preparation of soaps by saponification of fats and fatty oils. Calcium and barium hydroxides are specified bases.  The reactants may be subjected to the high rate of shear in a Gaulin homogenizer, a paint or ink mill, a Morehouse mill or a pressure viscosimeter.  The mixture of reactants may be subjected to the high rate of shear in the reaction zone or the mixture may be continuously circulated between the reaction zone and a treating zone, subjection to the high rate of shear taking place in the treating zone. Alternatively, separate streams of the reactants may be subjected to the high rate of shear and then mixed or a partially reacted mixture of the reactants may be subjected to the high rate of shear to complete the reaction.  The preparation of the barium salt of p-iso-octyl phenol sulphide is described wherein a slurry of hydrated barium hydroxide crystals in oil and a separate stream of the alkyl phenol sulphide in oil are mixed and subjected to a rate of shear of about 50,000-500,000 reciprocal seconds at about 175-225 DEG  F.ALSO:A lubricating grease composition is prepared by mixing together an inorganic metallic base and a soap-forming organic acid or an ester thereof in a lubricating oil and subjecting the mixture to a rate of shear at least 50,000 reciprocal seconds prior to the substantial completion of the soap-forming reaction. Suitable, soap-forming organic acids and esters thereof are high molecular weight fatty acids, such as stearic, behenic, erucic, oleic and hydrogenated fish oil fatty acids, and animal and vegetable fats and oils, such as lard, tallow, rapeseed oil and hydrogenated fish oil.  The mixture may be subjected to the high rate of shear in a Gaulin homogenizer, a paint or ink mill, a Morehouse mill or a pressure viscosimeter. Apparatus for the preparation of lubricating greases according to the method is described.  In the examples, lubricating greases are prepared according to the method from (1) hydrated lime, hydrogenated fish oil fatty acids, acetic acid, di- 2 - ethylhexyl sebacate and phenyl alpha - naphthylamine, (2) hydrated lime, hydrogenated fish oil fatty acids, acetic acid and mineral oil (3) hydrated lime, oleic acid and mineral oil and (4) hydrated lime, tallow, mineral oil, calcium chloride and water.

Title: Process for the manufacture of esters of polycyclic alcohols
IPC: C01B33/32
Filed: 1935-04-08
Abstract: Esters of polycyclic alcohols are prepared by subjecting esters of the male sexual hormone androsterone to the action of such reducing agents are capable of transforming the keto group into a secondary alcohol group.  The reduction may be applied either to the pure esters or to the impure preparations obtained from natural materials, for instance by the method described in Specification 438,515.  The preferred reducing agents are catalytically activated hydrogen, or nascent hydrogen.  In examples: (1) 3-acetyl-androsterone is reduced by hydrogen in the presence of a nickel catalyst; (2) the phthalic acid ester of the male hormone is hydrogenated in glacial acetic acid solution by hydrogen in the presence of platinum black. Specification 443,463 is referred to.  Samples have been furnished under Sect. 2 (5) of (1) the hydrogenation product produced by the action of hydrogen in the presence of platinum black on the monobenzoic acid ester of androsterone; (2) the hydrogenation product produced by the action of hydrogen according to the method of Adams - Schriner on androsterone acetate.  The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specifications 452,447, 455,018, 455,019, and 455,264.  This subject-matter does not appear in the Specification as accepted.

Title: A semi-conductor arrangement
IPC: B65B51/14

Abstract: 975,827. Semi-conductor devices. SIEMENSSCHUCKERTWERKE A.G. March 24, 1961 [March 24, 1960], No. 10959/61. Heading H1K. A semi-conductor device has two electrodes alloyed to opposing surfaces of a semi-conductor body 1, the electrodes being attached to two terminal members which are in turn attached to the inner surface of a hollow insulating body to form a space enclosing the device. The length of the electrical surface leakage path is arbitrarily determined by choice of the dimensions of the insulating body. In one embodiment alloyed electrodes 2, 3 are alloyed or soldered to tungsten, molybdenum or tantalum blocks 4, 5 and a ceramic cylinder 8 is soldered to the latter using a solder containing titanium or zirconium, or by premetallizing the ceramic surface. The resulting enclosure is preferably gas-tight. In another arrangement (Fig. 2, not shown), a small block of tungsten is soldered to each of the alloyed electrodes, a flexible molybdenum disc is soldered to each tungsten block, and a copper block is soldered to each disc, the periphery of each disc being attached to the insulating cylinder to act as a diaphragm. If a P-N junction in the semi-conductor body intersects the outer periphery of the body (Fig. 3), the periphery may be bevelled to prevent both sides of the junction touching the insulating tube. The cylinder may be stepped so as to partially project over the edges of the terminal blocks. The soldering and electrode alloying operations may be carried out in a single step. A plurality of devices may be clamped between bus-bars to form a high-power rectifying circuit (Figs. 4 to 7, not shown), each terminal being first clamped to a finned cooling block, or itself being provided with fins. If desired, a fuse may be connected in series with each device.
