Title: Variable pitch fans
Inventor: MONTGOMERIE GEORGE ALAN
IPC: F04D29/36
Filed: 1963-04-18
Abstract: 1,044,203. Axial-flow fans. SERCK RADIATORS Ltd. April 9, 1964 [April 18, 1963; Jan. 20, 1964], No. 15270/63 and 2347/64. Heading F1C. In a variable pitch fan comprising a hub assembly with a number of blades mounted thereon for angular movement about radial axes, the hub assembly includes means interconnecting the blades so that they may move in unison and resilient means urging the blades towards maximum pitch positions, the arrangement being such that when the fan is rotated the blades are urged towards minimum pitch positions. The fan may be used as a cooling fan for vehicle I.C. engines. Each blade 11, Fig. 2, is connected to a cylindrical root piece 25 pivoted at 26 to a hub portion 12 and carrying a peg 27 which locates a hole in a hub portion 13. The latter is bolted at 20 to a flange 21 of a drive shaft 22 and carries a pivot 16 about which the hub portion 12 may be angularly rotated to vary the pitch of the blades between maximum and minimum settings, limited by the abutment of sleeves 18, welded to radial arms 19 of the portion 13, against the sides of apertures 17 in the portion 12. A pre-torsioned spring 23 connected at its ends to the portions 12, 13 biases the blades to their maximum pitch setting, and the blades are urged towards their minimum pitch setting when the fan speed is such that the reaction of air on the blades is sufficient to overcome the spring loading. In an alternative embodiment, Fig. 6, the blade roots have a number of recesses or projections which coact with projections or recesses in dished hub plates 28, 29. The recesses and projections may be in the form of bevel gear teeth or the blade root may have a single peg projecting at opposite ends through a pair of holes formed respectively in the two plates. The plate 29 is secured to a ring 34 to form a pulley and to a sleeve 35, and the plate 28 is pivotable about the sleeve 35 to vary the blade pitch, limited by one or more pegs 33 extending into arcuate slots in the plate 28.

Title: Improved method of producing malleable metal pipes
IPC: B21C37/14
Filed: 1929-05-16
Abstract: 317,720. Weir, E. Aug. 20, 1928, [Convention date]. Drawings to Specification. Tubes; cased forms.-A malleable metal tube is made from a hollow blank by placing metal, of a lower melting point than that of the blank, within the hollow and then heating and flattening the blank on to the inserted metal after which the blank is rolled, reheated and rolled down on an inserted mandrel. The inserted metal may be in the form of strip, rod, tube, granules or paste and prevents adhesion between the opposite walls of the blank when the latter is flattened. The inserted metal constitutes a lining in the finished tube. Specification 316,212 is referred to.

Title: Improvements in or relating to magnetic amplifiers
IPC: G05B11/01
Filed: 1955-05-27
Abstract: 769,186. Magnetic amplifiers. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. May 27, 1955 [June 8, 1954], No. 15356/55. Class 40 (4). In a magnetic amplifier in which the level of magnetization of a saturable core is set in one direction by a control circuit and is subsequently taken back to saturation by a firing circuit, the firing circuit includes a transistor 26 connected with windings 24 and 28 such that when current flows through coil 24 from a D.C. source 22, winding 28 holds transistor 26 conductive, but when saturation is reached no further voltage is induced in coil 28 and transistor 26 ceases to conduct. Conduction through the transistor 26 is initiated by a pulse applied to terminals 36, the pulse being of greater magnitude than the bias 62 which normally holds the transistor unconducting. The control circuit may simply comprise a winding 40 to which an input signal is applied, but as shown it includes a transistor 60 and a winding 70 to break the circuit of the winding 40 during the interval when transistor 60 conducts. This is effected by winding 70 in which a voltage is induced to overcome the bias of 72 and prevent transistor 60 conducting. A load 12 is connected to a winding 44 which may alternatively be connected in series or parallel with winding 24. The period during which the control voltage sets the core 16 may be of longer duration than the period during which the transistor 26 is caused to conduct. In consequence the power output at the load 12 during a firing period will be greater than the power input during a setting period. The control coil 40 may be dispensed with and the control voltage can be applied directly across the coil 24. If the control voltage is allowed to take the core 16 from saturation in one direction to saturation in the other direction, the sudden increase in current in the control winding on reaching saturation may be utilized to set the transistor 26 in the firing circuit conducting. As shown in Fig. 4, the transistors 26 and 60 may be held alternately conducting and non-conducting by voltages in windings 86 and 88 of a transformer, the primary winding 84 of which is fed with an alternating voltage having a square waveform.

Abstract: 1,035,037. Typewriters. GERAETEWERK KARL - MARX - STADT VEB. April 19, 1963, No. 15509/63. Heading B6F. A case-shift mechanism for a page-type teleprinter is characterized in that the type carrier 1, Fig. 1, having a plurality of groups of type characters, is coupled by a rod 2 to a beam 4, the ends of which are connected eccentrically to adjusting elements 10 and 11. The elements are operated by controlling means to move the rod and carrier to a selected shift position, pawls 16 ... 19 being provided which in conjunction with lugs 15, 14 on the elements limit the movement of the elements and hold the same in the selected shift position. In the embodiment shown in Fig. 1, the type carrier 1 can be shifted selectively to three different positions by selective operation of the adjusting elements 10 and 11, in the form of cams, which are mounted loosely on the parallel shafts 8, 9, respectively, to which they may be coupled independently of each other by control means (not shown) having friction clutches. The cams 10 and 11 are provided with pins 12 and 13, spaced at a distance h from the axes of the shafts 8, 9, respectively, which distance corresponds to the case shift. The pins 12, 13 cooperate with slots 5 and 6 in the ends of the beam 4. Each cam 10 and 11 is provided with a pair of pawls 16, 17 and 18, 19. In operation the shafts 8 and 9 are caused to rotate at a speed according to the typing speed. Pawls 16 ... 19 are released one pair at a time by mechanisms (not shown) the pawls 18, 19 being used for shifting the type carrier 1 to the upper position (Fig. 4, not shown), pawls 17, 18 for shifting the type carrier to the intermediate position, Fig. 1, and pawls 16, 17 for shifting the type carrier to the lower position (Fig. 2, not shown). In further embodiment in Fig. 6 (not shown) wherein the type carrier is shifted to two positions only, the cam 10 is dispensed with and the slotted end of the beam 4 connected to a fixed pin 21.

Title: Crystalline sugar products
IPC: C13B30/02
Filed: 1960-05-05
Abstract: A dry substantially non-hygroscopic, non-caking, crystalline sugar product capable of dissolving in water more rapidly than granulated sucrose, is composed of fragile fine grain aggregates of rough, jagged, porous crystals containing predominantly sucrose and up to about 10% by weight of starch, based upon the weight of sucrose, and has a density of not more than 46 pounds per cubic foot; the product may also include up to about 10% of invert sugar, dextrose, lactose, corn syrup solids or dextrin.  The term "starch" includes tapioca, potato, wheat, oat, waxy grain sorghum and corn starches, acid-modified, enzyme-modified and oxidized starches, starch fractions, and starch derivatives such as mono-starch phosphate, starch acetate, and carboxymethyl starch.  A fondant cream or cake icing may be prepared by thoroughly mixing a sugar product consisting of 90% sucrose, 8% corn syrup solids and 2% starch, with betwetn 10 and 15% by weight of the sugar product, of water.  The sugar product is prepared by rapidly evaporating an aqueous solution of sucrose containing starch in an amount of between about 1% and 10% by weight of sucrose solids, which solution has a Brix value between about 50 degrees and 75 degrees, until the Brix value is increased rapidly to between about 90 degrees and 97 degrees, mixing the resulting supersaturated aqueous solution while reducing the temperature to between about 180 DEG  and 230 DEG  F. and while the product crystallises, and continuing the mixing of the resulting crystalline product until its temperature is reduced to below about 100 DEG  F. Examples are given.
