Title: An improved method and apparatus for feeding machines for forming glass in discontinuous sheets
IPC: C03B13/02
Filed: 1928-12-08
Abstract: 302,283. Soc. Anon. des Manufactures des Glaces et Produits Chimiques de St.-Gobain, Chauny, et Cirey. Dec. 13, 1927, [Convention date]. Rolling. - Relates to the method of making sheet glass in which a mass of glass q, Fig. 1, is poured from a ladle p or a melting-pot on to a receiving- table d whence it passes between rollers a, b and is formed into a sheet. According to the invention, a plate i is used to prevent the glass from flowing between the rollers until it has spread out evenly between side plates e. The plate i is then raised and the mass of glass advances towards the rollers a, b with a rectangular leading-edge, so that the sheet is formed with a straight leading-edge and wastage of glass is reduced. The plate i may be secured to arms g which are pivoted to the frame of the machine or to the side plates e, so that the plate is raised when the arms are swung backwards. The table d, instead of being flat, may have its upper surface rounded or formed with a central ridge to assist in spreading out the mass of glass. The face .of the plate i, against which the glass is poured, may also be curved or angular, and its lower edge may be in contact with the table for only a part of its length.

Title: Improvements in brown sugar
Inventor: LACHMANN ALFRED
IPC: C13B50/00
Filed: 1959-10-28
Abstract: Granular brown sugar is rendered resistant to caking by adding to and coating the sticky molasses layer on the sugar crystals with from 1 to 10% by weight of a relatively non-hygroscopic, edible, pulverulent, solid substance and drying the sugar to reduce the moisture content to less than 1%, preferably to a small fraction of 1%.  The coating substance may be organic, e.g. starch, dextrin, cereal flour, pulverulent sugar such as dextrose, lactose, fructose and confectioners' sugar, dextran, organic esters such as sucrose stearate, proteins and proteinaceous foods such as casein, egg albumin and milk powder, or may be partly organic and inorganic, e.g. calcium lactate, and magnesium stearate, or entirely inorganic, e.g. tricalcium phosphate, sodium silicoaluminate, and calcium silicate; if desired, a combination of two or more coating materials may be used, either in admixture or applied separately as successive coatings.  The brown sugar, which may be partially pre-dried, e.g. to a moisture content of 1.5 to 2%, before coating, is dried after coating by agitation at an elevated temperature e.g. 180 DEG  to 200 DEG  F., at which the molasses layer is plastic, and then cooled, whilst agitating, to a temperature preferably below 90 DEG  F., alternatively the coating material may be added to the dried brown sugar, i.e. whilst still hot from the drying process before cooling. The final brown sugar product may be pulverized.  A convenient apparatus for effecting the process is described and comprises, in sequence, a mixer for mixing the sugar with the coating substance, a rotary drum hot-air dryer, a rotary drum type cool-air dryer, and either a screening device, e.g. a 10-mesh Tyler screen, to remove oversize granules, or a pulverizer.

Title: Improvements in or relating to electricity generating plant
Inventor: MOSS NORMAN
IPC: F16H37/00
Filed: 1960-10-25
Abstract: 999, 755. Automatic speed control. PLESSEY CO. Ltd. Oct. 12, 1961 [Oct. 25,1960], No. 36575/60. Heading G3R. In a speed control system for an alternator, having a three phase armature driven by an aircraft propulsion engine subject to speed variation and a field rotor 6 coupled through gearing 11,12 to a Roots-type air-motor 10, the three-phase output from the armature is fed via slip-rings 3 to supply lines 1 and a synchronous motor 21 driving a governor 20 which maintains the alternator frequency constant by actuating valves 18, 19 connected to an inlet 15 of the air-motor. At the cruising speed of the engine the alternator frequency is at the desired value and valves 18, 19 are both closed by the governor and the air-motor is stationary. When the frequency is low the valve 18 connects an air-supply, from a bleed on an engine compressor, to the air-motor, causing the air-motor to rotate the field rotor in a direction opposite to that of the armature imparted by the engine. Conversely, for a high frequency, valve 19 is opened by the governor to connect the inlet 15 to atmospheric pressure and allow the rotor 6 to be driven by the armature 4 through the coupling effect of the magnetic field. To start the engine, the air-motor is coupled to drive the engine by short-circuiting the armature by a device 2 and causing the alternator to act as an eddy-current starting clutch. It is stated that the arrangement of field and armature may be interchanged. Specification 952,982 is referred to.

Title: Process and apparatus for manufacturing thick threads from highly polymeric polymethylene terephthalate, and threads when thus manufactured
Inventor: BEZEMER ARIE
IPC: D01D5/08
Filed: 1958-11-13
Abstract: <PICT:0838696/IV (a)/1> Thick threads are made from polymethylene terephthalates, especially polyethylene terephthalate, by extruding the threads into a liquid bath, guiding them therethrough by one or more deflecting members, and thereafter stretching the threads to a few times their original length, the process being effected under conditions such that the threads at their first point of deflection in the liquid bath are at the second order transition temperature. Thick threads are defined as monofilaments of diameter not below 0.2 mm.  The threads are preferably guided over a curved surface at the second order transition temperature.  As shown, suitable apparatus may comprise an extender 1, measuring pump 2, spinning plate 3, bath 4, and one or more thread-deflecting members 9, 10, 11, the first deflecting member 9 being movably mounted in the direction of the thread travelling thereto and being kept in equilibrium by a member 15 (e.g. a spring) which maintains a constant tension in that portion of the thread which has not yet passed the first deflecting member. By means of the member 15 the apparatus can be so operated that the first deflection point will automatically coincide with the point of the thread having the second order transition temperature. Methods of measuring the temperature of the thread at the first deflection point are described.  The threads are withdrawn by rollers 12 and collected on winding roll 14.  The collected threads may then be stretched between roller quintets 16, 17 while subjected in chamber 18 to the action of saturated steam at 100 DEG  C., pulled under tension by draw-off rollers 19 through chamber 20, heated by steam at 120 DEG C. and wound-up.

On moving the pinion axially, the collar 70 acts via a spring 64 on a casing 66 fast with the pinion, the spring compressing if the teeth 16, 18 on the gears 14, 20 abut. Further axial movement of the collar and sleeve compresses the spring and causes the balls to act on an edge 60 of the grooves to turn the pinion 14 to allow meshing. The motor is started and rotation of the sleeve is transmitted to the pinion via the edge 84 of the grooves, and the balls. After the engine starts, over-running of pinion 14 causes the balls to run up slopes 96 of the grooves into the bores 42, 44 against springs 36, 38, where they are held by centrifugal force. The sleeve and pinion may then be withdrawn. The slope 96 may extend along the entire length of the grooves on the opposite sides to edges 60.

Abstract: 951,206. Control of A.C. motors. DICTAPHONE CORPORATION. Oct. 26, 1960 [Oct. 27, 1959], No. 36757/60. Heading H2J. [Also in Division G5] A split phase motor in a dictating machine is energized through a resistor 40, instead of directly from the power line 42, when the motor is running at no-load speed. This reduces the speed and correspondingly minimizes noise from the motor. When the motor is clutched to the record-driving mechanism, the resistor is shortcircuited by contacts 44, 46, so that full power is applied to the motor under load. The resistor is so proportioned that the full-load and no-load speeds are substantially equal. When clutch coil 26 is energized, roller 18 on arm 24 is moved to engage motor-shaft 16 and wheel 22. At the same time, contact 44 closes against contact 46. Specifications 783,249 and 910,739 are referred to.

Filed: 1960-10-26
Abstract: 965,242. Making honeycomb core; welding by pressure. G. F. KEELERIC. Oct. 26, 1960 [Oct. 26, 1959], No. 36809/60. Headings B3A and B3R. In welding stacked metallic sheets only at spaced points of welding the sheets are stacked with stop weld between adjacent sheets in areas where no welding is to occur and leaving void areas of bare metal contact, the stack is brought to welding temperature and pressure is applied uniformly and simultaneously over substantially the entire area of the stack. A stack 15, Fig. 1, of stainless steel sheets is sandwiched between sheets 21, 22 of asbestos or mica in a press 25, 26 and electrodes 28, 29 from a transformer 30 contact the ends of the stack. Direct current electromagnets 35 are arranged on both sides of the stack. The current supplied to the stack may be of 60 cycles per second frequency and the input current to the transformer primary may be passed through an arc formed between a conductive rod in sodium hydroxide solution and a rod at the surface of the solution. Alternatively, direct current may be supplied to the stack and alternating current of 60 cycles per second to the electromagnets. In making honeycomb material areas of the plates not to be welded are masked, e.g. by applying to the upper face of each plate aluminium oxide in ethylsilicate as bands 40, 40a, Fig. 3, the bands being staggered between the sheets so that metallic contact occurs only where the uncoated areas are. A rib 45, 45a of the masking material may be provided opposite the uncoated areas to induce buckling of the sheets. A stack so coated is welded and the block expanded to form honeycomb. For welding a stack of aluminium sheets 50, Fig. 5, the sheets are sandwiched between mica layers 54 and the composite stack is sandwiched between stainless steel plates 56, 57 insulated from the press by sheets 60, 61. Electrodes 65, 66 supply current from a transformer 68 to the aluminium sheets and current from a transformer 72 is supplied by electrodes 69, 70 to the plates 56, 57. Radiator cores may be produced using the method and the layers to be welded may be of foil. The applied current may be of higher frequency.
