Abstract: 341,844. Teaching reading. BLUM, C. R., 54, Badenschestrasse, Sch÷neberg, Berlin. Sept. 9, 1929, No. 27420. Drawings to Specification. [Class 146 (ii).] A band adapted to be moved at constant speed past an index mark for enabling an artist or artists to reproduce notes, words, &c. in correct rhythm is prepared by first making a sound record or curve of the sounds to be reproduced and subsequently marking on the band the sequence of pulses occurring in the series by observation of the variations in the amplitude of the sound record or curve, the distance between the marks bearing a fixed relationship with the distance between the corresponding points of the sound curve. The sound record may be recorded on a moving band by mechanical or photoelectric means, and is preferably produced by means of a piano or key-operated bells. The sound record and the band to be marked are moved together past an index mark and by observing the sound record the commencement of a pulse, whether it is accented or not and its duration can be marked. The main accents may be represented by dashes along one line and the secondary accents on a lower line ; and the lengths of the dashes represent the durations of the individual periods of time. The musical score or words are then considered and the corresponding notes or syllables are inserted on the band. If desired, from a sound curve representing the combined effects of a number of instruments, singers &c. a plurality of bands can be prepared for different groups or parts.

Abstract: 914,260. Semi-conductor devices. SIEMENSSCHUCKERTWERKE A.G. Aug. 18, 1959 [Sept. 30, 1958], No. 28189/59. Class 37. A process for the manufacture of a semiconductor device comprises alloying a gold foil to a silicon body to form an electrode, providing at least one face of a molybdenum carrier plate with a gold coating the thickness of which is not more than <SP>1</SP>/ 30 th of the thickness of the gold foil, and alloying the gold-coated face of the Mo plate to the electrode at a temperature between 400‹ and 450‹ C. The Au coating on the Mo plate may be bonded to the plate by flashing at 900‹ C. in an inert atmosphere; it may be applied in several layers, each being independently flashed. Alternatively, as in the transistor shown, the Mo plate 14 is coated with successive layers of Ni 15, Ag 16, and Au 17, each layer being electrolytically deposited and flashed at 800‹ C. Completely coating the Mo plate enables it to be soft soldered to a metallic supporting or cooling body, and protects it when the device is etched in, e.g. a 1 : 1 mixture of hydrofluoric acid and nitric acid. The disc-shaped body 10 of P-type Si has an alloyed annular base electrode 21 of B-doped Au, and emitter and collector electrodes 18, 13, made by alloying Sb-doped Au foils to the body. Finally, the collector electrode 13 is alloyed with the Au layer 17 on the Mo plate by heating to between 400‹ and 450‹ C.

Abstract: 243,526. Thornton, W. M. Nov. 27, 1924. Gas analysis.-In a miner's electric lamp in which heat due to the presence of inflammable gas causes a bi-metallic strip to make or break a circuit, the bi-metallic strip is in circuit with, or near to, a spiral or like heating device not dependent on catalysis but raised by the current to such a temperature that the inflammable mixture passing over it burns at the surface, the resultant radiant heat operating the strip. As shown, the heater H and bi-metallic strip G are connected together and respectively to contacts C, C<2> on an insulating disc D, the lamp E being connected to contacts C, C<1>; the lamp base A<1> is rotatable to bring accumulator contacts B<1> into engagement either with the contacts C, C<2> or C, C<1>. With the strip G in circuit and in the presence of a given percentage of gas, bending of the strip is such as to give contact with a screw J closing a circuit through the lamp casing to light the lamp E. The screw J is adjustable and carries a pointer J<2> co-operating with an adjustable scale K, whereby the apparatus may be set to indicate percentage of gas. A second screw contact may be provided which normally puts the lamp E in circuit, the circuit being broken in the presence of a given percentage of gas, or both forms of contact may be provided on a single screw. In a further form, the lamp and bi-metallic strip are in series, whereby in the presence of gas, the lamp is first extinguished and then lit on cooling of the heater through breaking of the circuit. The heater may be arranged in a readily renewable cartridge-like perforated casing. The screw J may be arranged parallel with the strip G and have a conical end adapted to engage the strip so that adjustment of the screw varies the point of such engagement.

Hydrocarbons, cracking; rectifiers. - The vapours from a still, in which mineral oils, or mixtures of coal, lignite &c. with crude or fuel oil, tar, pitch, &c. are cracked, are passed through a region in which a constant temperature is maintained by introducing into contact with the vapours a liquid such as water or benzol, or a mixture of liquids, having a constant boiling point. The constant temperature zone may be formed in a column or tower surmounting the still and containing trays, or a highly porous material onto which water, &c. is continuously or intermittently fed. The tower may be packed with Raschig rings. The condensate will normally be returned to the still. The temperature of the cracking still is 410-460‹ C., and the boiling-point of the liquid introduced into the constant temperature zone may be varied by using pressures of 5-10 kg. per sq. cm. for example a constant temperature zone of 165‹ C. is obtained when water is used and a pressure of 7 kg. per sq. cm. is maintained. The first Provisional Specification describes the invention as applicable generally in distilling and rectifying operations, and refers to the use of mercury for obtaining a constant temperature zone.

Abstract: 679,736. Mops. SANTMAN, J. E., and SANTMAN, A. F. Nov. 8, 1949, No. 28666/49. Classes 19 and 61 (i). A floor cleaner having a rigid or hinged frame connectable with a handle and intended for the attachment thereto of a soft cleaning plate of sponge material is characterised that in the side thereof intended for contact with the floor, the cleaning plate has one or more grooves into each of which an attaching rod may be inserted and connected with the frame in such a manner that during the cleaning operation the cleaning plate will be relatively flat against the floor without the attaching rod touching the floor surface. When a hinged frame is employed it is possible to squeeze out liquid from the moistened plate. In Figs. 1 and 2 the frame 4 consists of a single rigid rectangular piece, e.g. of wood. The cleaning plate 6 has a groove in the bottom side to receive an attaching rod 7 having two hook-shaped projections 7a which penetrate the plate, pass through holes 5c formed in the frame 4 and are caused to bear upon the upper side of the frame by axial displacement of the rod 7. A plate spring 15 engages the hook-shaped projection 7a and prevents accidental displacement of the rod. An inverted U-shaped plate is secured to the upper side of the frame so that its two arms bear upon the shaft 2, slots in the arms of the plate being arranged to engage an annular groove in the shaft. In Figs. 3 and 4 the frame consists of two co-operating clamping ribs 4a, 4b interconnected by double hinges 5 with connecting parts 5a. Projections 7a of the rod 7 are cooperable with the connecting parts 5a, one of. which is equipped with a plate spring 15 to prevent unintentional displacement of the rod 7. Rib 4b has a swingable lever 10 which may be employed as a handle to move ribs 4a and 4b towards each other when water will be squeezed out of the cleaning plate 6.

In the present application the core tube 14 is sealed at its upstream end around the advancing core, by a layer 28 of heat resistant and low friction material which is compressed around the advancing core by a gaseous or liquid inflated elastomeric collar 26. The collar may be an endless, or spirally lapped tube, or a tube 26, as shown. The layer 28 may be integral with the collar 26, but preferably comprises a helical lapping of a stranded rope or cord of fluorocarbon polymer, e.g. polytetrafluoroethylene, which may be graphite filled. Any unravelling tendency of the cord, during inflation of the collar, may be restrained by one or more tape lappings of opposite hand to that of the rope, and of a material which is the same as, or compatible with the cord. The layer 28 and collar 26 may be restrained against displacement with the core, by being located between walls 29, 30. In the described embodiment, the core comprises an aluminium conductor of sector or segmental shape, around which is extruded from an annular extrusion outlet, a polyethylene covering which is cured in passage through the chamber containing steam, the pressure difference between the steam and nitrogen in the core tube being maintained by automatic control of the steam and/or nitrogen pressure, and/or by automatic control of leakage of nitrogen from the core tube. The core may also be of pre-spiralled configuration.
