Patent GB-273130-A (GB)
Abstract: 273,130. Greve, J. E. Oct. 15, 1926. Adding-apparatus for British monetary or other non-decimal values. - A single-bank, independently-operated machine of the type employing a field of key-set stops 14 mounted on an escapement-controlled carriage 15, is adapted for decimal or non-decimal calculation according to a preliminary setting, and the arrangement is such that when the machine is set in condition for decimal calculation the stops are placed beyond the range of the non-decimal denominational actuating and recording members. In the application of the invention to calculating in British currency, the type-bar 115<1> carries type 0-11 and has two movable overlapping stops 51, 52 and a fixed stop 53 for co-operation with the standard field of stops 14. When either of the 10 or 11 keys is depressed one or both of the stops 51, 52 is displaced by key connections 54, 55 to enable the type-bar to increase its upward travel accordingly. The stops are retained by spring detents and are restored to normal position, when the carriage returns, by the action of a cam 66 on a lever 63 bent up at its left hand end to engage stop 51. When non-decimal calculations are to be performed the key 70 occupies its outer position (Fig. 6) and through a pin and cam slot 90 disposes a slotted plate 92 endwise so that slots 92<1> are in the paths of the actuating sectors 38 belonging to pence and shillings denominations. The slot 92<a> however for the tens of shillings sector is only slightly longer than is necessary for the registration of unity so that if by error a key of value greater than 1 is struck the addition of 1 only will be made and the type 1 will be disposed slightly above the line thus rendering the error apparent. To calculate in the decimal notation, key 70 is pressed in and is thereupon retained by shoulder 73 catching beneath the guide plate 71<a>. A pin 88 on a spring-influenced rod 79 being thus freed the rod assumes the position shown in Fig. 1 wherein a shoulder 86 is in the path of a pin 85 on the arm 47 fast on the main shaft 46. Thus when after the number has been set up the crank handle 44 is rocked to operate the machine, the pin 85 forces the rod 79 to the left which in turn rocks a stop 74 away from the slidably-mounted escapement tooth 28. This tooth is thereupon forced by the carriage to the left to the extent of three places with the result that the set stops are placed beyond the range of the pence and shillings type-bars. Moreover by virtue of the pin and slot 90 the plate 92 is shifted to put the slots 92<1>, 92a out of line and thus prevent any movement of these type-bars and the correspond. ing actuating racks. The conditioning of the machine for adding or subtracting may be controlled by the paper carriage instead of by the key 70.

Title: Improvements relating to the extraction of unsaponifiable constituents from wool grease
IPC: C11B11/00
Filed: 1948-10-21
Abstract: The unsaponifiable constituents of wool grease are obtained by saponifying wool grease with a quantity of alkali amounting to between 4 per cent and 200 per cent in excess of that theoretically required for complete saponification, partially neutralizing the saponified mass with sulphuric acid, phosphoric acid, hydrochloric acid or a mixture of such acids in quantities sufficient to reduce the pH of the mass to a value which corresponds to between 8.5 and 11.0 in a sample of one part by weight of the mass mixed with five parts by weight of water, and extracting the mass with a halogenated hydrocarbon solvent.  As solvent there may be used ethylene dichloride which may be added before or during the partial neutralization with the acid. Preferably the solvent extraction is carried out at 40 DEG  to 65 DEG  C. Detailed examples are given.

Title: Electronically switch differentiating or rate of change circuit
IPC: H03C1/58
Filed: 1956-09-10
Abstract: 809,091. Phase sense sensitive circuits. COLLINS RADIO CO. Sept. 10, 1956 [Oct. 6, 1955], No. 27636/56. Class 38 (4). [Also in Groups XXXVI and XL (c)] In an electronically switched differentiating circuit (Fig. 1) diodes D1, D2 are connected in series with each other and with resistances R1, R2 across the secondary of A.C. energized transformer 22 in parallel with diodes D3, D4 also in series with each other and with resistances R3, R4 but opposed in polarity to D1, D2. Charging capacitance C1 connects to earth the balance adjustable tap of potentiometer Rb across the transformer secondary, while an A.C. input signal of variable amplitude and similar phase and frequency to the transformer excitation is applied over resistance R5 (high compared with R1, R2, R3 and R4) to the junction of D1, D2 and a pulsating output signal of amplitude representing the rate of change of the input is derived over capacitance C2 from the junction of D3, D4 and is shunted to earth by high resistance R6. The diode series resistances are equal and the potentiometer may be eliminated by connecting C1 to an accurate centre tap of the transformer secondary. Alternate half cycles of the transformer excitation drive D1, D2 conducting to charge C1 slowly over R5 to a direct voltage representing the instantaneous input peak amplitude and drive D3, D4 conducting so that C2 is charged slowly from C1 in series with R6. For a constant input, the voltages on C1, C2 become equal, so that zero current flows in R6 for zero output, and for a variable input it is shown that the output signal amplitude represents the rate of change of the input amplitude. The circuit is stated to operate as a narrow bandpass filter centred at the frequency of the transformer excitation, and to produce an output only when the latter is in phase or antiphase with the input; the output being zero for quadrature therebetween. Resistances R1-R4 produce voltage drops on diode conduction to reduce the effective positive voltages on the diodes in the conducting direction; thus permitting the application of a larger peak-to-peak voltage, which thus in the non-conducting condition drives the diode anodes far beyond their inherent control potentials to achieve a high value of impedance therein. The diodes are replaceable by semi-conductive resistances. In an equivalent device (Fig. 2, not shown) a vibratory switch excited by the commutating A.C. source alternately charges a capacitance from the input series resistance and discharges it into the output resistance/capacitance network.

[Also in Division D1] In a direct spinning and drawing process for preparing serviceable fibres having improved tenacity, elongation, and dimensional stability, a fibre-forming thermoplastic polymer, such as polyamide, polyester or polyolefin, is melt spun and the as-extruded filaments are subsequently drawn without winding them up as a package, and then wound as a package, the speed of the as-extruded filaments being maintained at 150 to 350 m./min. and the temperature of the filaments being maintained between the glass transition temperature for the polymer used and 70‹ C. above that temperature at the start of drawing, the drawing ratio being 3-5 to 5. The drawn filaments may be twisted in known manner whilst being wound up, or they may be given a false twist and heat set simultaneously with the drawing. In one embodiment (Fig. 2) the polymer extruded from the spinneret 1 reaches drawing roller 3 after passing round a heated roller 2 and a false twister 5, and is collected on a wind-up bobbin 6. Rollers 2 and 3 rotate at different speeds to give the desired draw ratio, and the temperature and speed of roller 2 is maintained within the limits specified above.

[Class 40 (v)] A superheterodyne receiver comprises a " reflexed " pentagrid valve 1 which serves as a combined local oscillator, mixer, and intermediate-frequency amplifier. The intermediate frequency oscillations are fed through a transformer 11 to the diode electrodes of a diodetriode valve 13, the resulting rectified signals built up across a resistance 14 being passed back through a lead 16, condenser 17, and potentiometer 18 to the control grid e of the pentode. Here they are subjected to one stage of low-frequency amplification, and are then passed on from the primary winding of the output transformer 11 through a condenser 20 to the control grid of the valve 13 which serves as a second L.F amplifier. In a modified arrangement, the rectified signals from the valve 13 are fed back to the pentode through a high-frequency choke shunted by an acceptor circuit tuned to the intermediate frequency.
