Abstract: 437,159. Typewriters. HINZ, G. H., 12, Schalkerstrasse, Gelsenkirchen, Germany. Feb. 11, 1935, No. 4331. [Class 100 (iv)] Alarms.-In last-line alarms comprising a spring contact which is normally separated by the sheet from a contact on the platen, a battery and bell are enclosed in the platen, and the circuit includes the frame of the platen-carriage, and the shaft of the platen. In the alarm shown in the Figure, a battery 2 and bell 4 are mounted in the platen 1, the bell-support 3 being formed as a cap which fits on the battery. The battery terminal 5 rests on a metal sleeve 6 in the platen, and the battery terminal 5<1> is connected to the bell terminal 7, the bell terminal 8 being connected to a contact spring 9 which is secured to the battery by a clip 10.

Title: Process for continuous high-speed bleaching of cellulosic textiles
IPC: D06B17/02

Abstract: 990,181. Bleaching cellulosic materials. OLIN MATHIESON CHEMICAL CORPORATION. Feb. 5, 1962 [Feb. 7,1961], No.4350/62. Headings D1L and D1P. Cellulosic textiles are bleached by a continuous, high-speed process at a rate of at least 5, 000 yards by a process comprising:- (A) continuously passing them through a dilute aqueous solution of a mineral acid having a concentration by weight of 0.1-2.0% and expressing the acid solution to 90-120% by weight of the textiles, (B) retaining them in an acidification zone for 5-60 minutes to effect uniform acidification of the solution on the textiles, (C) continuously washing them to remove excess acid and to produce textiles wet with a solution containing 0.01-0.25% of acid based on their dry weight, (D) continuously passing them through an acid aqueous solution containing 1-50 grams per litre of sodium chlorite at a pH of 3-5 at a temperature between room temperature and 110F. and expressing all but 90-120% of the aqueous bleaching solution to provide textiles wet with 0.1-1.5% of sodium chlorite based on their dry weight and (E) retaining them in a bleaching zone at a pH lower than 4 for 10-120 minutes at 180-212F. Suitable mineral acids are sulphic, hydrochloric and phosphoric acids. The bleaching solution may also contain sodium nitrate in the proportion of more than one mole of sodium nitrate per mole of sodium chlorite and 0.1-1% by weight of a surface-active agent, e.g. salts of acyl alkyl taurides, sulphated alcohols or alkyl aryl sulphonates. Fabrics comprising cotton, linen, jute, hemp or regenerated cellulose fibres alone or in admixture with nylon, polyester or polyacrylonitrile fibres may be treated. In the apparatus preferably used to carry out the process the fabric is passed through acid saturator 11, excess acid is remove by squeeze rollers 16 and the fabric is stacked into the longer arm of S-shoot 19 to provide time for the acidification of the fabric. It'is then washed in washers 22 and 25 squeezed by rollers 28 and passed through saturator 30 into which the chlorite solution is introduced via line 31. It is then squeezed by rollers 32 and held in the longer arm of S-shoot 35 heated by steam either by means of a jacket or direct steam lines (not shown) where bleaching takes place.

Title: Improvements relating to abrasive materials
IPC: C09K3/14
Filed: 1949-02-17
Abstract: An abrasive material of corundum type comprises a mixture of light or dark corundum with a corundum produced by hydrolysis of a sulphide-containing corundum melt.  The latter is known as H-type corundum and is of high purity.  It has a greater hardness and higher resistance to wear than white corundum which also has these properties.  The dark corundum is the toughest and at the same time the softest.  The light corundum is intermediate in properties between the white and dark corundums.  A mixture of 20 to 80 parts of H-type corundum and 80 to 20 parts of dark and/or light corundum is specified.  The abrasive material may be used for making abrasive wheels, stones, paper, cloth and other abrasive articles.

Abstract: 1,139,831. Liquid-gas contacting apparatus. OLEOSTIN. 1 Feb., 1966 [6 Feb., 1965], No. 4400/66. Heading B1F. Liquid in a tank 70 under vacuum and heated by coils 72, e.g. -oil to be deodorized or fatty matter to be hydrogenated, is continuously caused to circulate upwardly, through an open ended chimney 78 immersed in the liquid by means of steam injected at a controlled rate through a pipe 82 into the chimney base, the induced flow of the liquid being controlled by a throttle device which is in the form of a throat constriction. An emulsion having a density lower than one tenth of the density of the untreated liquid is produced in the chimney. The steam enters through a nozzle or distributor box, and the controlled flows are such that the specific gravity of the emulsion generated by distillation in the chimney is reduced to about one tenth of that of the liquid. The chimneys may be fanned with convolutions, as in Fig. 4, to lengthen the path therethough. A plurality of chimneys working in parallel or series may be disposed in a tank, with steam injected into the base of each chimney. In the plant of Fig. 5, oil enters by conduit 100 into a first compartment defined by one end wall and a partition 94a. Treated oil leaves through a conduit 104 opening into the last compartment defined by the other end wall and a partition. 94n having passed through each chimney in turn. Deflection members 96a-96n guide the emulsion from compartment to compartment.

Title: Electrical circuit employing a semiconductor
IPC: H03K3/286
Filed: 1955-02-16
Abstract: 766,210. Transistor two stable state circuits. PHILCO CORPORATION. Feb. 16, 1955 [Feb. 17, 1954], No. 4632/55. Class 40(6) In a circuit employing a transitor 10, a predetermined bias is maintained on the collector 13 by connecting a diode 35. to an impedance 24 across which a voltage equal: to the bias is maintained. The circuit is described as applied to a two-stable state circuit employing transistors 10, 11 one of which is fully conducting while the other is in a cut-off condition. The collector 13 is connected over resistors 26,' 27 to the base 17 of transistor 11, a similar network of resistors 23, 24 connecting the collector of transistor 11 to the base 14 of transistor 10. Positive going input pulses are applied over capacitors 29, 31 and diodes 30, 32 to the bases 14, 17 of the transistors. With transistor 11 in the on state the collector current is heavy and the collector voltage is just below earth potential. Due to the potential divider 23, 24 and resistor 20, the. base 14 is maintained positive with respect to the emitter 12 to maintain the tran-' sistor 10 cut off, the collector 13 being near negative supply voltage due to the low collector current. The low collector potential is fed over resistor 26, 27 to the base 17 of transistor 11, the diode 36 preventing the collector from approaching the base potential too closely. It is found that this arrangement enables the circuits to reverse more quickly. Since the collector. potential of the transistor 11 is higher than that of transistor 10 the diode 32 is biased less negatively than diode 30. As a resultthe positive triggering pulses are fed over diode 32 to the base 17 of transistor 11 to reverse its state. The following -pulse is. fed over diode 30 to the base 14 of transistor 10.
