Title: Improvements in or relating to alternating current measuring instruments
IPC: G01R19/22
Filed: 1936-05-22
Abstract: 477,392. Pressure meters. BLUMLEIN, A. D., and WHITE, E. L. C. May 22, 1936, No. 14449. [Class 37] A thermionic valve voltmeter for measuring small alternating potentials, comprises a diode rectifier followed by a D.C. negative-feed-back amplifier having a D.C. meter in the output circuit thereof, the negative feed back being such that the response of the meter is substantially independent of the amplifier valve characteristics. The alternating potentials to be measured are applied through a transformer 2, Fig. 1, and full wave diode rectifier 1 to a load resistance 3 shunted by the usual condenser 4 and connected between the grid of the triode amplifier 5 and a tapping on a potential divider 11, 6, connected across the H.T. supply, the grid being raised above earth potential by connecting the centre tap of the secondary of transformer 2 to a point 10 on the resistance 11. Negative feed back is obtained by the resistance 7 and that of the milliammeter 8 in the cathode lead common to the anode and grid circuits, this resistance being large relative to the reciprocal of the mutual conductance of the valve 5 whereby the response of the meter is rendered substantially independent of the amplifier characteristics. The milliammmeter is provided with a backing- off resistance 13, connected to a tapping on resistance 6 for annulling the initial steady current therein, the meter then reading the voltage directly. Resistances 6, 13 may be omitted however and allowance made for the standing current in the meter. A small non- inductive resistance 14 in the grid circuit prevents self-oscillation of the valve 5. In another embodiment, for measuring positive peak potentials across a resistance 17, Fig. 2, a single diode rectifier 1<1> is used, the load resistance 3 of which is connected to a tapping on the potential divider 18, 19, 21, 22, since it is assumed that a D.C. potential exists across the resistance 17 as well as the alternating potentials to be measured. The resistance 19 supplies negative grid bias to the valve 5, and negative feed back is provided by the common meter resistance and resistance 19. Negative peak potentials may be measured by reversing the connections between the diode and the amplifier. In both embodiments the meter may, alternatively, be connected between the anode and H.T. supply.

Title: An office machine with a printing device for symbols, particularly for dates
Inventor: GROSS WILLY
IPC: G06C11/04
Filed: 1955-05-20
Abstract: 795,312. Selective printing OLYMPIA WERKE AKT.-GES. May 20, 1955, No. 14591/55. Class 100(4) A device forming part of an accounting machine or like apparatus for printing several items, such as particulars of date by several standardized tendigit type carriers, comprises a series of driving members 22-22e one for adjustment of each of the characters to -printing position, pivoted on a shaft 21 supported in the machine frame and guided in a comb 23. Each member 22-22e is connected by a corresponding rod 25-25e with a corresponding type carrier 26-26e pivoted on a pin 27 guided in a comb 28 and forced to move for printing against a platen 30 by a printing segment 29e. The driving members 22-22e has steps R, 0-4 and a bent stop y engages a corresponding limiting member 20-20e provided with counter stops 5-9. Each limiting member 20-20e is pivoted on shaft 19 and guided in comb 11. It can be adjusted by gear segment 16 and pinnion 15 by adjusting corresponding wheel 14-14d on shaft 13 and held in adjusted position by pawl 17. A zeroizing bar 24 restores all the driving members in a clockwise direction into end position. The type carrier 26e is also moved by rod 25e to lowermost position. On release of member 22e by bar 24 it is turned by spring 31 to engage with stop x of member 20 with one of its steps depending on the adjustment of the member, or stop y of driving member 22e with one of stops 5-9 of member 20. Member 22e thus turns type carrier 26e by rod 25e and adjusts it to selected character. If stop x is arrested by step R no character is printed. Adjusting wheels 14-14d corresponding respectively to digits 0-9 for days 1-31 of month and two vacant ones, 14b serves to set the months and one vacant one and 14c, 14d serve for digits 0-9 and two vacant positions for the number of the year, are mounted free on shaft 13 supported on walls of machine frame and each is rigidly connected to the year segment 16 which engages one of the pinions 15. The set values are transmitted from the adjusting wheels 14-14d through members 15, 16 to members 20-20e which limit in accordance with their adjustment the stroke of their corresponding driving members 22- 22e by stops x, y which are formed by bending portions out of the plane of one member into the range of movement of the other members to give mutual interengagement, A letter r or y is printed complementary to Ma to distinguish "March" from "May" on the type carrier member, and a third letter is printed on each month indication by a limiting member 20d which is angularly set positively through the same angle as the member for adjusting the months. Roman numerals may be used if desired. The adjustment steps of the limiting members 20-20e for two or more tendigit type carriers 26-26e may have the same syllables and the same complementary letters arranged once only on the associated type carriers with the twelve step adjustment effected by steps of equal height and the driving member has a tenstep limitation.

Title: A new or improved process for waving hair
IPC: A45D7/00
Filed: 1962-04-16
Abstract: Hair is waved by curling it around a curler having a diameter greater than 10 mm, treating it with a reducing agent, e.g. ammoniumthioglycolate, terminating the treatment with the reducing agent by the application of a neutralising agent, e.g. hydrogenperoxide, and subsequently rinsing and drying it, a force sufficient to produce an elongation of at least 0.5% being imparted to the hair after winding on the curler and before or during the treatment with the reducing agent.  The force producing elongation may be maintained until after the rinsing and is preferably maintained until a few minutes before the end of the drying operation.  When the drying has been completed the hair may be left at ambient temperature for several minutes and the curler then removed.  The force producing elongation may be arranged to produce an elongation proportional to the diameter of the curler and inversely proportional to the diameter of the hairs being treated. The elongation may be imported to the hair by means of a curler in the form of two shell halves each having a clamp for securing the hair to the shell and a pair of conical inserts adapted to be screwed towards one another to effect separation of the two shell halves.

Filed: 1939-05-17
Abstract: 549,955. Centrifugal separators. AKTIEBOLAGET SEPARATOR-NOBEL. May 17, 1939, Nos. 14728 and 14729. Convention dates, May 17, 1938, and Aug. 23, 1938. [Class 23] [Also in Group III] In a process for separating wax poor in oil from mineral oils in two or more centrifuging stages by treatment with solvents of a specific gravity different from that of the wax, chilling, separation of the wax and further treatment of the latter with the solvent, cooled solvent is added to the wax obtained in the first centrifuging operation before feeding the wax into the second centrifuging operation. The process may be carried out in a two-stage centrifugal bowl, the cooled solvent being added to the wax on its way between the two centrifuging stages. As solvents naphtha, and mixtures of aromatic hydrocarbons with ketones and esters, such as a mixture of benzene and acetone, are specified; solvents heavier than wax, e.g. trichlorethylene, may also be used. In the arrangement shown, in which a solvent such as naphtha lighter than wax is used, the cooled wax-bearing hydrocarbon mixture consisting of starting material and diluent is fed through a pipe 1 into the supply chamber 3 of the centrifuge, whence it flows through channels 4 to a first separating chamber 5 provided with discs 6 where the diluted oil fraction is separated from the wax, the oil fraction flowing through a chamber 8 and channel 9 to a discharge outlet 10 from which it is thrown into a collecting vessel 11, while the wax flows back into the chamber 5, whence it passes through an opening 7 to a chamber 12. On its way to the chamber 12 the wax is diluted with a cooled diluent, e.g. naphtha, which may be supplied through a pipe 14 fed from a channel 16 bored in the spindle 15 of the centrifuge. A second separation of wax takes place in the chamber 12, the liquid passing to the outlet 20 and collecting vessel 21 while the wax is discharged through the channel 22 and outlet 24, which may be provided with a regulating disc, to the collecting vessel 25. The wax passing through the channel 22 may be rendered less viscous by means of a heating medium, such as steam, directed from a pipe 26 against the outside wall of the channel, or the wax may be mixed with diluent supplied through channel 27. Instead of discharging the wax through an open outlet, a detaching member, such as a paring disc, may be used for removing the wax from the bowl. The wax may also be discharged through nozzles or valves located in the outer wall of the bowl.
