Patent GB-479477-A (GB)
Title: Improvements in and apparatus for the continuous manufacture and production of polymerisation products of acetylene
IPC: C07C2/38
Filed: 1936-09-24
Abstract: <PICT:0479477/IV/1> Acetylene polymerization products, particularly monovinylacetylene, are made by a continuous process in which, as described in the parent Specification, a gas of low acetylene content (up to about 20 per cent) is led into an acidic cuprous salt solution at such a low temperature and at such a velocity that the gas emerging from the solution is practically free from acetylene and its polymerization products.  The solution is then regenerated and used again as described in the parent Specification, but the process of the parent Specification is modified in that, after the solution has been treated with the gas of low acetylene content, it is further treated with a gas of high acetylene content, this treatment being effected before and/or during the regeneration of the solution.  The gas of high acetylene content may be separately generated, e.g. from a carbide, or it may be the gas remaining after polymerization products have been separated from the gases evolved during the regeneration of the solution.  As shown, a gas obtained by the electric-arc treatment of methane is passed from a gas-holder 1 by a pump 2 to an absorption column 3 through which is led, in the same direction as the gas, an acidic cuprous salt solution containing a salt of ammonium or of an alkali or alkaline-earth metal.  Waste gas practically free from acetylene and its polymerization products escapes from the top of the column 3, and the solution is passed from the column 3 to a second absorption column 4, to which a residual gas of high acetylene content is supplied from a gas-holder 10 by a pump 11.  The gas of low acetylene content emerging from the column 4 may be led partly to the gas-holder 1 and partly to the gas-holder 10. The solution passes from the column 4 to a column 5 in which it is heated, the gases evolved, after removal of water in a condenser 7, passing through a drier 8 to a cooler 9, wherein the polymerization products are separated, the residual gas of high acetylene content passing to the gas-holder 10.  The regenerated solution is passed by a pump 12 from the column 5 through a cooler 6 to the column 3.  By means of the pump 11, gas of high acetylene content may also be passed from the gas-holder 10 to the column 5.  An example illustrating the operation of the apparatus described is given.  The apparatus described may be modified in that (1) the gas of low acetylene content may be led in counterflow to the solution in the column 3, (2) the solution may be circulated by the gases, on the mammoth-pump principle, (3) the gas of high acetylene content may be passed entirely to the column 5 and then to the column 4, the unabsorbed residue from the column 4 passing to the gas-holder 1, (4) the solution may be led from column 3 directly to column 5, and treated therein with the gas of high acetylene content.  The absorption in the columns 3 and 4 may be effected at atmospheric or raised pressure.

Abstract: 505,472. Ice-cream; food preparations. NEWLY WEDS BAKING CO., and ANGELL, P. M. Sept. 7, 1938, No. 26149. [Classes 28 (i) and 49] In the production of a composite ice-cream cake roll, the cake dough contains cake flour, a substantial quantity of soya-bean flour, and sufficient shortening to impart to the baked cake, moisture and flexibility retaining qualities. The dough is baked for three, minutes, at a relatively high temperature, e.g. 600 to 650‹ F., so that steam is generated during the baking without extracting an appreciableamount of moisture from the dough, and to prevent the formation of a crust. The following proportions of ingredients are referred to ; 120 pounds of granulated sugar, 30 pounds of vegetable shortening, 12 pounds of soya-bean flour, 2 pounds 5 ounces of baking soda, 2 pounds 5 ounces of table salt, 45 pounds of whole eggs, 20 pounds of Dutch process cocoa, 16 pounds of sweetened skimmed condensed milk, 132 pounds of soft winter wheat cake flour; 280 pounds of water and 5 pounds of baking powder. A steamy atmosphere is maintained in the oven, e.g. by closing the oven damper. The dough is baked in pans having paper liners on their bottoms, and the baked cakes are removed from the pans with the aid of projecting flaps on the liners, or, the pans are inverted to deposit the cakes upon a paper liner 12a:, which, as shown, is . used to facilitate the rolling-up of the cake 15 after the application of the ice-cream layer 17. The roll is then refrigerated to render it self-sustaining. If the cakes are to be transported before being associated with the ice-cream, they are packed in cartons with the paper liners interposed.

Title: Improvements in or relating to headlight control arrangements for motor vehicles
IPC: B60Q1/14
Filed: 1953-09-25
Abstract: 730,455. Photo-electric headlamp dimmers. FORD MOTOR CO., Ltd. Sept. 25, 1953 [Sept. 25, 1952], No. 26431/53. Class 40 (3). In a photo-electric headlamp dimming system the output of an oscillator controlled by the photo-cell is amplified in a radio receiver to operate the dimming system. As shown, light incident on a photo-cell 12 from the headlamps of an oncoming vehicle triggers an oscillator comprising cathode-coupled triodes 10, 11 forming a multivibrator. This oscillator produces a signal above the audible range which is amplified in the triode section of the usual double-diode triode 15 forming part of a conventional radio receiver; The amplified signal is fed to an output pentode 16 having in its anode circuit a toned relay 17 responsive to the oscillator output to operate the dimming system. A three position switch 18 is provided which in its top position removes the plate supply for the valves preceding valve 15 of the radio receiver which is thus inoperative, in its middle position breaks the heater supply of the oscillator so that only the radio receiver is operable and in its bottom position renders both the receiver and oscillator operative.

Title: Improvements in and relating to rotary speed governors
Inventor: ROSE DENNIS
IPC: G05D13/08
Filed: 1952-10-21
Abstract: 778,245. Speed governors. ULTRA ELECTRIC, Ltd. Jan. 13, 1954 [Oct. 21, 1952], No. 26444/52. Class 57. In a rotary speed governor a fluid subjected to centrifugal force is contained in a hermetically sealed axially extensible cylindrical chamber 3, Fig. 1, coaxial with the governor shaft 2 and controlling the axial displacement of a rod 6 actuating the speed controlling means. The chamber 3 consists of a bellows mounted in a casing 1 and provided with radial vanes 7. A second bellows 4 also filled with fluid and in communication with the bellow 3 is attached to the rod 6. When the governor is rotated, the bellows 3 expands axially against the resistance of a spring 5 and draws fluid from the bellows 4 which thus displaces the rod 6. The bellows 4 may be arranged inside the bellows 3 which may be replaced by two concentric bellows to form an annular chamber. Alternatively, the extensible chamber may consist of a rigid cylinder closed at one or both ends by a flexible diaphragm stiffened over most of its area. To render the governor linear in operation, a square-law spring may be used for the spring 5 or, alternatively, the spring may be arranged to act on the bellows 3 through levers 9, Fig. 4, and cams 8 which vary the mechanical advantage of the levers in accordance with the setting of the governor. Fig. 5 shows a governor in which the relation between the rotational speed and the movement of the rod 6 is modified by the rate of change of rotational speed. When the governor is accelerated, fluid in a bellows 13, being acted upon only by friction, takes a certain time to reach the new speed. Thus, the rod 6 is moved to a position beyond that corresponding to the new speed before being retracted by the action of the bellows 13 to its correct new position. If the bellows 12, 13 are of equal size, the governor will respond only to rate of change of speed. A governor in which the relationship between rotational speed and displacement of the rod 6 may be controlled by varying the shape of end members of a bellows partly or wholly filled with fluid, is also described. Immixible fluids having differing specific gravities and viscosities may be used in the bellows.
Patent GB-1065461-A (GB)
Title: Annealing glass sheets
IPC: C03B25/08
Filed: 1965-06-23
Abstract: A method of annealing a glass sheet supported upon its bottom marginal edge portions during its movement through an enclosed atmosphere through its annealing range wherein the remainder of the bottom surface, not in contact with the support, is directly exposed to the atmosphere and the exposed portion of the bottom surface of the glass sheet is cooler than the upper surface of said glass sheet as the glass sheet cools through the annealing range, comprises selectively imparting heat to a lower portion of the enclosed atmosphere facing the bottom surface of the sheet during its movement through the annealing range both to reduce the difference in cooling rate between the bottom marginal edge portions in contact with the support and the remaining exposed bottom surface, and to reduce the natural vertical temperature gradient from the bottom surface of the glass sheet to the top surface thereof. In a preferred embodiment a glass sheet is supported at its marginal edges by a skeleton-type bending mould 34 which is conveyed through heating, bending and annealing zones on stub rollers 12 (Fig. 2, not shown).  Radiant heaters in the furnace roof bring the sheet to near its softening temperature. It is the conveyed through the bending zone where, having been brought to its softening temperature by roof radiant heaters 46 (Fig. 1, not shown) and "crease" heaters 48, it sags into and takes the shape of the supporting mould 34.  The bent sheet supported upon its mould is then conveyed into and through the annealing lehr.  In the zone the temperature of which decreases from just above to just below the annealing range 1/4 -inch cold rolled steel plates 56 (Figs. 2 and 3, not shown) are placed along the length of lehr floor and extend across the width of the floor. Similar plates 58 are fitted inwardly of the side walls of the lehr above the stub rollers 12 but below the top of the curved-up ends of the bent sheet.  These plates 56, 58 serve to absorb and re-radiate some of the heat and thereby reduce the temperature gradients which may occur along the bottom surface of and through the glass sheet. In an alternative embodiment (Fig. 4, not shown) the steel plates 56, 58 may be dispensed with and horizontally movable gas burners inserted along the length of the lehr-side wall through the annealing range at such a height that the flames are directed towards the bottom surface of the glass sheet.  If desired, only the side-wall plates 58 need be removed.
