Title: Process of moulding chocolate
IPC: A23G1/28
Filed: 1928-02-10
Abstract: 311,361. Marks, E. C. R., (Postum Co., Inc.). Feb. 10, 1928. Casting and moulding chocolate.-The known process of casting chocolate into plates or bars in which moulds on an endless carrier, which are charged with the molten material, are passed through a cooling chamber before the solidified contents are removed, is modified by cooling " relatively rapidly at a substantially uniform rate " to such a point that the material contracts relatively to the metal mould and thus can be removed readily therefrom without breakage. In the preferred method for producing plates of oneeighth of an inch in thickness, a three-stage cooling is adopted. The moulds, charged with material at about 85‹ F., spend about 4 minutes in traversing a chamber maintained at 55‹ F., then a further 8 minutes in traversing a second chamber maintained at 45‹ F. during which solidification occurs, and finally spend another 4 minutes in traversing a low temperature chamber during which the relative contraction occurs to permit ready detachment from the walls of the mould.

Title: Telephone subscriber station
IPC: H04M1/60
Filed: 1958-02-11
Abstract: 873,139. Substation circuits. GENERAL TELEPHONE LABORATORIES Inc. Feb. 11, 1958 [March 20, 1957], No. 4447/58. Addition to 858,678. Class 40 (4). A subscriber's subset is provided with pushbutton operated contacts which connect up loud-speaking facilities and disconnect the handset, the push-button being restored to remove the loud-speaker by a linkage associated with the cradle switch when the handset is taken down. The substation circuitry is shown in Figs. 1 and 2 where the receiver and transmitter of the handset are connected in the anti-sidetone circuit of hybrid 20 with switchhook contacts 30 and a calling buzzer 52. The impulse transmitter controls off-normal and impulse contacts 54 to 56. The push-button operated contacts are shown at 40 and divert the line 11 from the handset to a socket 63 which also takes the leads to a loud-speaker 61 housed in a separate cabinet. A plug 64, mating with socket 63, connects line 11 to twostage transistor amplifier 160, 170, for speech outgoing from microphone 101, and to twostage transistor amplifier 180, 190, for incoming speech to loud-speaker 61. The amplifiers are powered from the exchange over a rectifier bridge 70 such that voltages applied to the transistors remain of the same polarity when voltage on the exchange line is reversed. As the bridge 70 always takes D.C. from the line it provides a path for speech currents to and from the hybrid 85. The D.C. supply for the amplifiers is protected from speech by a filter comprised by capacitors 77 and 89 and the coil 75. To adjust the supply in face of varying lengths of exchange line a variable resistor 76 is provided. The microphone 101 is matched to its amplifier by a potentiometer 104 and the volume of the loud-speaker output is controlled by a potentiometer 131. All the components of Fig. 2, with the exception of the microphone 101, are mounted on a plate with the four pin plug 64 so as to be detachably secured to the base of the subset. The exterior casing of the subset carries a grille, behind which the microphone 101 is mounted, and a control knob for the volume control 131, see Fig. 4, not shown. As well as the cradle switch plungers 34, 35, Figs. 6A, 6B, two push-buttons 44 and 45 are provided on the subset. Depression of pushbutton 44 operates the spring set 40 to connect up the loud-speaking system and disconnect the handset and is sufficient to answer a call. Providing the handset is in place the pushbutton 44, once depressed, will stay down, as shown in Fig. 6B, and can be released by depressing button 45 which, by pivoting lever 236, raises button 44 from between the spring-set arms 242. Should button 44 be depressed and the handset be lifted the cradle switch pivot arms 215, 216 move from the positions shown in Fig. 6B to those shown in Fig. 6A, and a spring 254, the portion 261 of which slides in a hole in the end of lever 237, is drawn downwards to engage the lever with a hook 262 and raise the button 44 to connect up the handset.

Filed: 1938-02-18
Abstract: 502,987. Beryllium ; alloys. GARDNER, D. Feb. 18, 1938, No. 5088. [Class 82 (i)] [Also in Group III] Beryllium ores are treated for the production of beryllium by heating a mixture of the ore and carbonaceous material such as coal or coke in sulphur vapour or a gaseous or vaporized non-metallic sulphur compound such as carbon bisulphide or sulphuretted hydrogen to about 1800-2000‹ C. to convert the beryllium into sulphide which is further treated to extract the beryllium therefrom. The sulphidized mass may be treated with hydrochloric or sulphuric acid, the solution of beryllium chloride or sulphate being freed from aluminium and iron, and the beryllium obtained therefrom as oxide ; or the sulphidized mass may be heated with hydrochloric acid gas or chlorine and the mixture of chlorides separated by fractional distillation, the beryllium chloride being converted into oxide or sulphide. The beryllium oxide obtained may be again converted to pure sulphide, which is reduced to beryllium by heating with aluminium, calcium, strontium, barium, or magnesium, in a reducing or inert gas such as hydrogen, hydrocarbons, helium, or argon ; a flux such as beryllium fluoride may be added. In some cases the beryllium sulphide may be mixed with copper and reduced by aluminium, or the sulphide may be reduced by a mixture of aluminium and copper. The beryllium may be obtained as an alloy with the reducing metal, and separated therefrom by distillation. Beryllium alloys may be obtained by collecting the distillate in a molten charge of a metal such as copper, nickel, aluminium, magnesium, lithium, or alkaline earth metals. Specifications 482,467, 482,531, and 483,862 are referred to.

Abstract: 1359885 Tempering glass E W WARTENBERG 23 Feb 1972 [1 March 1971] 5703/71 Heading C1M In thermally treating glass, to produce a predetermined central tensile stress therein, by heating to a temperature near its softening point and quenching in a body of liquid maintained at a selected temperature, the body of liquid is selected to give the predetermined central tensile stress from a family of silicone oils of similar chemical structure whose viscosities at the selected quenching temperature are distributed over a defined viscosity range which corresponds to a predetermined range of central tensile stress to be induced in the glass. The suggested families of silicone oils are methylpolysiloxanes and phenylmethylpolysiloxanes. If no particular oil gives the required stress, oils of higher and lower viscosities than the necessary viscosity are mixed in proportions to give the necessary viscosity. For soda-lime-silica glass 3 mm. thick, the silicone oils of the family have viscosities at 100‹ C. in the range from 3 to 120 centistokes. The glass to be toughened may be flat or bent sheets or articles such as containers, bottles, tableware, insulators and hollow glass blocks.
