Title: Improvements in or relating to fountain pens
IPC: B43K24/08
Filed: 1947-06-07
Abstract: 635,144. Reservoir pens. MABIE, TODD, & CO., Ltd., and HEARD, F. G. June 7, 1947, No. 15067. [Class 146 (iii)] A ball-point fountain pen of the type in which the writing point is normally held in a surrounding casing but may be projected for use against spring pressure by a knob comprises a lateral pin disposed between two opposed series of teeth formed or provided within the pen body, said pin being adapted to be positioned through guidance by the sloping sides of said teeth within one of a number of relatively deep slots formed between said teeth to locate the writing point in retracted position or within one of a number of relatively shallow spaces formed between said teeth to locate the ball point in writing position. The ball point pen 6 is projected against the action of a spring 9 by a knob 12 carried on a plunger 11 rotatably and slidably mounted in a sleeve 10. The sleeve 10 is screwed to the pen casing 1 and carries two sleeves 14 and 15 provided with teeth 16 and 17 offset by approximately half a pitch in relation to one another. The upper sleeve 14 is formed with elongated slots 18 which normally accommodate pins 13 carried by the plunger 11. When the knob 12 is depressed the pins 13 move out of the slot 18 and engage inclined portions of the teeth 17 which tends to rotate the plunger 11 so that when pressure is released from the knob 12 the pin 13 is retained by one of the teeth 16 thus holding the pen 6 in a projected position. The process is repeated to retract the pen. In a modification the sleeves may be revoluble, and the plunger 11 may be constrained to reciprocal movement only.

Title: Improved manufacture of glue or the like
IPC: C09H3/02
Filed: 1924-06-26
Abstract: A solution of gelatine or glue is freed from crystalloid or semi-colloid impurities by an ultrafiltration process, preferably carried out with the application of pressure or suction and at a temperature at which the solution does not gelatinize.  The solution may be stirred, or filtered upwardly, to obviate clogging of the ultrafilter membrane, which may be prepared by coagulation of a four per cent collodion solution in acetic acid.  The process may be repeated a number of times, the purified product being diluted before ultrafiltration, and flocculent impurities appearing in the course of the process may be removed by passing the solution through an ordinary filter.  The ultrafiltration may be assisted by passing an electric current through the solution, one electrode touching, or being extended upon, that side of the ultrafilter which is in contact with the air, and the other electrode being either immersed in the solution or, preferably, separated therefrom by a diaphragm which may also act as an ultrafilter.  The solution is preferably maintained as neutral as possible during the process.

Abstract: 1,061,231. Differential thermal analysis. COMMISSARIAT A L'ENERGIE ATOMIQUE. April 14, 1964 [April 26, 1963J, No. 15497/64. Heading G1N. In a device comparing the energies released by a specimen sample 1a, Fig. 3 (such as irradiated graphite), and a reference sample 1b, when the two are subjected to the same temperature increase, the reference sample 1b is heated in accordance with a predetermined programme (e.g. a linear increase), and the heating of the specimen sample 1a is controlled in accordance with the temperature difference measured between the two samples; each sample comprising two similar discs 2a, Figs. 1, 2 (not shown), of the appropriate material, with a heating element (5a) sandwiched between them. The two samples 1a, 1b are suspended, by their electrical connections, inside a container 14 and are surrounded therein by two heating cylinders 23, 26. The container may be filled with or surrounded by liquid nitrogen in a Dewar flask 19, and in the latter case the container may be evacuated. A thermocouple 6a-1 measures the temperature of the specimen 1a, and thermocouples 6a-2 and 6b-2 measure the difference between the two sample temperatures, while thermocouples 6b-1 and 29 measure the reference sample temperature relative to the cylinder 26. A control circuit Fig. 4 (not shown), contains a loop (B1) which receives a signal (##) representing the temperature difference between the samples, amplifies it in a chopper amplifier (44, 45), filters it (at 47) and controls (at 50) the specimen sample heater current (at 5a), so that the sample temperatures bear a fixed relation to each other and may for example be equal. Thermocouples 51a, 51b) produce voltages proportional to the square of the respective heater currents, and hence to the heater powers, and the difference #p between these powers is indicated on a recorder (54), together with the temperature #a of the specimen sample 6a-1. A second loop (B2) in the control circuit contains a motor (55) responsive to a portion of the temperature difference signal tapped off the B1 loop between the amplifier (45) and a demodulator (46), and the motor controls a potentiometer positioned (between 47 and 48) in the B1 loop. This second loop enables corrections for long term drift to be made, and the initial zero to be set. A loop similar to B1 is used to control the temperature of the heating cylinder 26 in response to thermocouples 6b-1 and 29.

Title: Method for the production of metal powders such as those known as bronze colours
IPC: B22F9/00
Filed: 1931-05-27
Abstract: In the manufacture of bronze powders and particularly aluminium powder, the powder is subjected to treatment in an atmosphere comprising a gas which is inert relatively to the powder, and a small proportion of an oxidizing gas: the inert gas avoids the danger of explosion due to rapid oxidization of the aluminium, and the oxygen produces a protective film of aluminium oxide on the particles whereby further oxidizing action is reduced.  The atmosphere preferably comprises nitrogen mixed with 1-3 per cent of oxygen: it may be obtained by the combustion of illuminating gas, carbon, or liquid fuel, with the addition of excess air sufficient to provide the necessary amount of oxygen.  The oxygen may be replaced by water vapour, and the atmosphere may be continuously or intermittently renewed.  In a specific example, a rotating drum in which metal powder is flattened into foils is filled with a mixture of nitrogen and 3 per cent of oxygen, and a quantity of the gas is passed continuously through the drum so as to oxidize the powder and effect a continual withdrawal of finished particles from the drum.

Abstract: 273,680. British Thomson-Houston Co., Ltd., (Assignees of Pratt. W. H.). June 29, 1926, [Convention date]. Induction relays. - In a polyphase instrument of the induction disc type having current and potential driving-magnets, one of the magnets has two coils energized from different phases, means being provided to ensure that the fluxes due to these two coils are substantially in phase with each other and bear a desired phase relation to that of the other magnet. The invention is applicable to induction torque elements for power relays, but is shown applied to an induction motor meter. Fig. 1 shows the circuit connections of a meter for measuring the energy of a two-phase three-wire system 14, 15, 16 derived from a three-phase Y-oonnected source of supply 10 having a neutral wire 12. The conducting disc 22 of the meter is driven by the co-operation of a potential magnet 17, having a winding 18 connected across the mains 14, 15, and a current magnet 19 having two windings 20, 21 connected, either directly or through current transformers, in the mains 14, 15. Each coil 20, 21 is divided into two sections wound on the two main legs of the core. The currents flowing in the mains 14, 15 are 120‹ out of phase, and means are provided for bringing the fluxes due to these currents into phase with each other in the series magnet 19. This is effected by connecting a reactance 23 in series and a resistance 24 in shunt with the coil 20 and a resistance 25 in series and a reactance 26 in shunt with the coil 21. The coils 20, 21 are made mutually non-inductive by winding as shown in Fig. 2 on a laminated core 19 magnetically divided, except at the pole faces, into two sections 27, 28. The two parts of the coil 20 are wound on sections 28 and the two parts of the coil 21 are wound on section 27. It is also applicable to systems with other phase relations, for example quarter-phase three-wire systems. Alternatively the potential magnet instead of the series magnet may be double wound.
