Porous compositions.-Porous plates for electrolysis or elctro-osmose or for filtering liquids or gases have chromium oxide as base material. Several methods of making the plates are described. According to one method, chromium oxide is mixed with organic or other compounds of chromium, for example chromic acid or chromium nitrate, which when heated yield chromium oxide. The mixture is pressed into moulds and heated. The porosity of the product will vary according to the proportions of the mixture, the pressure, and the temperature and duration of heating. The porosity may be increased by adding to the mixture other materials, such as common salt or sawdust, which are burnt during the heating or afterwards removed by solvents. According to a second method chromium oxide with which chromium trioxide may be mixed is sintered, and the solid body obtained is given the required shape by grinding. According to a third method chromium oxide is mixed with a binding agent, such as cement, and allowed to set.

Title: Improvements in solutions for use in coating metals
IPC: C23C22/13
Filed: 1936-04-22
Abstract: A coating bath or replenishing liquid for use in a phosphatizing process consists of a solution containing one or more metallic dihydrogen phosphates to which has been added nitric acid in quantity sufficient to avoid the presence of insoluble phosphates formed by hydrolysis.  The nitric acid, which may be added before, during, or after the dissolution of the phosphates, reacts with the phosphates to form soluble nitrates, which act as accelerators, and free phosphoric acid which inhibits hydrolysis of the phosphates, and, as an alternative procedure, one or more p  soluble metallic nitrates and free phosphoric acid in quantity sufficient to inhibit hydrolysis may be added direct to the solution instead of adding nitric acid. Dihydrogen phosphates of zinc, iron, manganese, calcium, cadmium, and barium may be used in the solution and may, if desired, be formed therein by chemical reaction.  Solutions specified are formed by dissolving in water (a) zinc dihydrogen phosphate, nitric acid, and copper carbonate; (b) zinc dihydrogen phosphate, zinc nitrate, phosphoric acid, and copper carbonate.  In making solution (a) the nitric acid is mixed with the water prior to or simultaneously with the addition of the phosphate and during the solution of the phosphate the solution is heated to 70-80 DEG  C. which is approximately the temperature at which the coating bath is normally used.

Patent GB-569020-A (GB)
Title: Improvements in means for starting internal combustion engines
IPC: F02F3/00
Filed: 1943-07-15
Abstract: 569,020. Starting. CROSS, R. C. July 15, 1943, No. 11541. Drawings to Specification. [Class 7 (v)] In a two-stroke engine, a motor-driven pump or pumps are arranged to feed combustible mixture into the pre-eompression and combustion chambers of the engine so that the engine can be started by starting the pump or pumps and then firing the mixture, there being a charge in the pre-combustion chamber ready for compression before being fired on the second piston stroke. The general construction is identical with that described in Specification 569,063. An oval cylinder 2 (see abridgment of Specification 569,063) houses a piston 1 sfidable along a splined shaft 7, complementary splines on the bush 9 of the piston engaging the shaft to rotate it as the piston moves. The bush 9 slides within a sleeve 10 surrounded by a coil spring 17 which returns the piston to the inner end 3 of the cylinder, where ignition of a combustible charge drives it outwards again. At starting, an auxiliary carburetter 21 supplies combustible mixture to two vane pumps 23, 24 which respectively force the mixture into the combustion chamber above the piston and a pre-cornpression chamber below it. When sufficient pressure has been built up in the combustion chamber to displace the piston, a little distance outwards, the piston movement closes the ignition circuit and the mixture is fired. Alternatively, a fluid-pressure switch may control the ignition. As the piston moves outwards it uncovers an inlet port 12 connected by a transfer passage 13 with a port 14 in the pro-compression chamber and the compressed charge enters the combustion chamber until the skirt of the piston closes the port 14. The remaining charge acts as a buffer to check the piston movement until a port 14a in the piston skirt uncovers the port 14. The shaft 7 is operatively connected to a larger internalcombustion engine to start it.

Title: Method of making crustless confectionery, such as chocolate confectionery, liquid filling
IPC: A23G3/20
Filed: 1957-04-10
Abstract: Crustless confectionery, i.e. confections with an outer covering, e.g. of chocolate, and an inner filling, e.g. of liquid, and no intervening sugar crust, are made with a sugar crust and a filling with an initially high viscosity which consists of a substance capable of swelling and filling materials capable of making said substance swell, the filling being such that it will gradually liquefy and dissolve the sugar crust.  The substance capable of swelling may be hydrolized starch (e.g. hydrolized cornflour) or pectins and the filling materials may include milk and sugar solutions as well as cocoa powder, nougat mass, aromas, fruits or fruit pulp.  The covering may be a cocoa mass or a fat-containing nougat mass made of almonds, hazel nuts, ground nuts or the like. The sugar solutions may be aqueous or alcoholic.  Alcohols, e.g. glycerine or sorbitol, may be included in the sugar crust to accelerate the solution of the crust.  The confectionery is made by rolling sugar or sugar syrup mass into a thin sheet, winding it over a pipe and withdrawing it as a continuous tube.  This tube is filled and then stamped out to form the confection which is then coated.  In Example 1 the crust is formed from saccharose and glucose and the filling is made by mixing 0.3 kg. hydrolized corn starch with 3 kg. sugar and dissolving or swelling it in 7 kg. water.  80 gm. citric acid and 50 gm. cherry aroma are then added.  Examples 2 and 3 describe the making of a strawberry filling and a chocolate filling.
