IPC: F16H1/28
Filed: 1932-05-20
Abstract: 386,519. Epicyclic toothed gearing. STOECKICHT, W., 3, Erika-Strasse, Solln, Munich, Germany. May 20, 1932, No. 14407. Convention date, June 23, 1931. [Class 80 (i).] In order to equalize the loading of the planet pinions 2 of helically-toothed epicyclic spur gearing, theinternallytoothed annulus 3 is tiltably mounted about the centre of the' gearing. The sunwheel 1 also may be tiltable or, in epicyclic gearing without an external annulus, the sun wheel alone is tiltable. As shown, 'the annulus 3 is carried by pins 10 in a gimbal ring 9 supported by pins 11 in the stationary casing 8, centring of the annulus being allowed by play along the axis of the pins. The axial reaction of the helical teeth on the sun wheel 1 is taken by a thrust-bearing on its shaft, the reaction couples on the planet pinions 2 by stub-axles 4 on the planet carrier (not shown), and the axial thrusts on the annulus 3 by the universal mounting, whereby the annulus adjusts itself to equalize the loads on the pinion teeth.

Abstract: 175,221. Owens, F. W., and Howells, D. J. May 24, 1921. Wind - screens. -In a wind-screen for vehicles comprising upper and lower transparent sections, the upper section is pivoted at its top edge and adapted to be angularly adjusted, while the lower section, to the bottom edge of which is attached an expanding or contracting screen, is arranged to slide in guides behind the upper screen so as to be protected by it. The angular gaps at the sides formed when opening the upper screen are closed by expanding or contracting lattice screens. The upper screen 3, Fig. 4, is angularly adjusted and the lower screen 4 slidden up behind it and locked in position by the spring bolt 14. The gap between the bottom 6 of the lower screen 4 and the dashboard of the car is closed by an expanding or contracting screen 7, which may be of the roller-blind type. The projection 13 forms a cover when the screen 7 is collapsed, and a protection from eddy-currents when the screen is in its raised position. The sides of the screen 3 and the vertical supports of the screen are connected by a lattice screen 19 of fan shape which closes in the angular gap when the screen 3 is open. The pivot 20, Fig. 5, of the upper screen 3, may be adjusted to any angular position by means of the pinion 22<x> on it, engaging with a toothed segment 23 which can be set in any position by means of the spring- actuated pawl 26 engaging in a recess in the casing. The spindle 24 is rigidly attached to the segment 23 and has a screwed end projecting beyond the casing which is fitted with a wing nut capable of maintaining the segment and casing in frictional contact.

Title: Improvements in shock absorbers
IPC: B60G13/04
Filed: 1923-06-04
Abstract: 202,247. Mitchell, H. R. June 4, 1923. Vibration-dampers.-In shock-absorbers of the kind which employ two series of friction drag plates, the shock-absorber is completely encased with adjusting-means operated from without the casing and all end thrust on the casing is obviated, and the shock-absorber is so arranged that there is a central neutral position within the limits of which the normal movements of the vehicle will cause relative oscillations of the frictional plates, which will be but little restrained but with greater movements the oscillations will be more strongly restrained. the upward movements of the vehicle body relatively to the axle being more strongly restrained than the downward movements. Two series of friction plates, comprising fixed plates 3 secured to the hub sleeve 1 mounted on the frame 4, alternate with oscillating plates 2 which are caused to oscillate by means of pins 22 with the arm 20 attached to the wheel axles. The plates 2 have studs 25 of some material such as cork. Pressure is transmitted to the friction plates by means of a spider 5 which projects through transverse openings in the hub member into the axial bore 1 thereof and is then acted upon by a spring 6 through the medium of cam discs 7, 8. The pressure is adjusted by means of nut 12. and the end thrust is taken up by a collar 100 mounted on the hub member. A casing 23 is provided, as shown. The cam disc 7 fits over the spider, and is non-rotatable, while the cam disc 8 is caused to oscillate with the arm 20 by means of the rod 9. The cam discs have cams 71, 81 which are higher than the cams 72, 82, and the discs are so proportioned that during normal oscillations the cams do not engage, and therefore do not compress the spring 6 to transmit pressure to the friction plates. When during abnormal oscillations the frames moves downward, the cams 72 and 81, 71 and 82 respectively will engage to check such movement through increased tension of the spring, while if the frame is thrown upward, cams 71 and 81 will engage, and consequently the maximum checking effect will be produced.

Abstract: 833,160. Control systems for arc-welding apparatus. AIR REDUCTION CO. Inc. May 9, 1958 [May 9, 1957], No. 14899/58. Class 38 (4). [Also in Group XL (c)] A time delay device comprises an electron discharge tube 5 in series with a relay 10 and an initiating device having two normally open pairs of contacts and one normally closed pair, a capacitor 17 being connected between the grid and, via one normally opened pair, to the negative supply terminal the side of the capacitor 17 remote from the grid being connected via a charging path such as R1 to the positive terminal. A variable resistance R2 in series with the other normally opened pair is connected between the grid and the positive terminal, the normally closed pair being connected between the grid and the negative terminal. As shown, the contacts of an initiating relay 13 first charge capacitor 17 via resistor R 1. The timed period is started by energizing the initiating relay 13 by means of a switch, not shown, so that the cathode is connected to the negative supply terminal. Capacitor 17 now discharges at a rate determined by the setting of resistor R2 and tends to recharge in the reverse direction so that the angle of incidence between the discharge curve and the critical voltage is large. When the critical grid voltage is reached, the gas-filled or vacuum tube fires or conducts, energizing relay 10 which closes a load circuit 18. The circuit is reset by releasing the initiating relay 13 so that the tube is cut off and the capacitor recharges. The device may be used to control the length of an arc welding period.

Title: Method and devices for wave frequency discrimination and digital measurement, using sampling and logic circuits
IPC: H03M1/00
Filed: 1967-03-31
Abstract: 1,123,641. Digital frequency measuring. COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 31 March, 1967 [4 April, 1966; 10 March, 1967], No. 14998/67. Heading G4H. In apparatus for measuring the difference between an unknown frequency and a reference frequency the unknown frequency is sampled for polarity at recurring instants, the samples being translated into binary signals ("1" and "0") and combined in differently spaced pairs in modulo 2 adders, the outputs of which are applied to majority decision circuits to determine whether "1's" or "0's" preponderate, the outputs of the decision circuits then representing in binary code the frequency difference to be measured. If a frequency of F is sampled at the same frequency successive pairs of samples will have the same polarity, i.e. they will both be represented by "1" or by "0". If any pair of pulses is added in a modulus 2 adder the output will be "0". If a frequency F is sampled at half this frequency, alternate samples will have opposite polarity and the adder will give "1". For input frequencies between F and half F some adder outputs will be "1" and some "0", the maj ority indicating that the frequency is nearer F or nearer half F. In the apparatus described, Fig. 2, sampling is effected by a diode gate 2 actuated by clock pulses 3. These pulses are applied as shift pulses to a trigger chain 101-132. The sample pulses from gate 2 are applied to the first stage 101 and the outputs of subsequent stages 102, 104, 108 &c., are applied with the output of gate 2 to half-adders 11, 12, 13 &c. The output of gate 2 and the output of stage 102 represent two samples of a series having a frequency of F. Similarly the output of gate 2 and the output of stage 104 represent two samples of a series having a frequency of half F and so on. Each of the half-adders gives a succession of "1's" or "0's" indicating that the two input samples had different or the same polarity. Majority decision circuits 21, 22, 23 &c., determine which predominate in each adder output, and give a binary signal at 31, 32 &c. These output signals then represent the difference between the input signal and the centre frequency of the band-width of the system. The majority decision circuits (Fig. 3, not shown), each comprise an auxiliary shift register the outputs of which are gated together so that if the majority of signals in the register are "1's" the output will be "1" and if the majority are "0's" the output will be '' 0 ''.

Title: Improvements in or relating to the production of arylaliphatic diamines
Filed: 1945-06-13
Abstract: p - Dialkylaminomethylbenzylamines are manufactured by condensing an aromatic nitrile, substituted in the p-position by a halogenmethyl group, with a dialkylamine and then reducing the cyano group to an aminomethyl group.  The products are starting materials for the preparation of industrial products such as detergents, cosmetics, vulcanization accelerators and pharmaceutical products.  In an example, 4-bromomethylbenzonitrile is heated with excess of diethylamine in alcohol and the resulting 4-diethylaminomethylbenzonitrile is reduced with hydrogen in tetrahydronaphthalene solution in the p  presence of a Raney nickel catalyst, yielding 1 - aminomethyl - 4 - diethylaminomethylbenzene. The Specification as open to inspection under Sect. 91 comprises also the manufacture of other arylaliphatic diamines of the general formula NH2 - CH2 - Ar - CH2 - NR1R2, wherein Ar represents an aryl group, which may be substituted by one or more alkyl or alkoxy groups, or both, and R1 and R2 represent the same or different alkyl or aralkyl groups, which may form part of a closed ring containing the nitrogen atom, which ring may contain a second hetero atom, e.g. oxygen or nitrogen.

Title: Improvements in apparatus for regulating the volume of flow or pressure of fluids
IPC: G05D16/20
Filed: 1920-06-03
Abstract: 144,304. Reineke, J. H. Feb. 23, 1918, [Convention date]. Switches, actuating; pneumatic.-Relates to valve apparatus for regulating fluid flow or pressure, of the kind described in Specification 144,283, [Class 135, Valves &c.]. When the pressure increases a bell float 36 rises and closes the contacts 24, 26 and short circuits a resistance 31, so that a three-phase motor, having slip rings connected to the wires 32, increases speed and operates to reduce the opening of the valve. When the pressure falls unduly the float 36 opens the contact 27 and cuts out an additional resistance 29, normally in parallel with resistance 30, so that the motor slows down, and increases the opening of the valve 1. When the fully open position is reached a sliding sleeve 12, moved outwards by a screw 11 on the shaft 10, abuts against the boss of the sprocket wheel 7 and disengages the dog-clutch 9 so that the wheel 7 stops. The valve is automatically closed, in the event of the fluid pressure failing, by means of a second bell float 38 which closes the switch contacts 34, 35 and short circuits the resistances 30, 31. This causes the controlled three-phase motor to run faster, and the valve is closed. In closing, a screw 6 operates a lever 4 whereupon a switch 2 is opened by a spring 5 and opens the circuits of both motors. The valve cannot be opened again until the switch 2 is closed by hand.
