Title: Improvements in and relating to the regeneration of lubricating oils
IPC: C10M175/00
Filed: 1926-10-16
Abstract: 268,284. Bensmann, H. [Firm of]. March 25, 1926, [Convention date]. Recovering waste lubricants. - The regeneration of used lubricating-oils, particularly those employed in internal-combustion engines or under conditions of high temperature, is effected by first treating them with a polymerizing agent such as tin tetrachloride, aluminium chloride, sulphuric acid, or phosphoric acid, at 40-70‹ C. in order to precipitate and remove the decomposition products and with them the finely dispersed carbon, and then filtering them through an adsorbent material, such as aluminium magnesium hydrosilicate, to eliminate organic acids and tarry matters. The oil may be heated to 40-50‹ C. in a vessel B provided with stirring-means M and be agitated with 1-3 per cent of the polymerizing agent for ¢ hour while the temperature is raised to 70‹ C. The sludge, containing the polymerization products and carbon, is allowed to settle and then drawn off through a cock 1. The oil is passed through a pipe 2 to a settling vessel A, and thence through a pipe 3 to a filter F adapted to be heated and having therein a perforated tray, covered by a filter cloth on which the adsorbent material is carried. Purified oil passes by a cock 4 to a container T. A vacuum vessel V, connected to the filter F by a pipe 5, serves to remove oil retained by the adsorbent.

Filed: 1951-11-09
Abstract: 690,609. Internal shoe - drum brakes. PORSCHE KONSTRUKTIONEN GES. Nov. 9, 1951 [Feb. 1, 1951], No. 26304/51. Class 103 (i). An internal shoe-drum brake of the kind in which the shoes are applied to the brake drum by means of a hydraulic cylinder 2 and piston 4 located outside the brake drum and operating against a two-armed lever 13, the other end of which projects within the brake drum, is characterized in that force is transmitted to the brake shoe webs by two expanding levers 11 and 12 which guide one another. The two-armed lever 13 is pivoted on the lever 12 and has a notch 21 by which it engages the lever 11, which is U-shaped to allow it to slide over the lever 12. The different lengths of the arms a and b of the lever 13 cause a greater proportion of the force exerted by the hydraulic piston 22 to be applied to the non-servo-shoe 8 so that the work done by each shoe is made more equal. Provision is also made for mechanical actuation by means of terminal 25 interlocked with a guide-piece 23 in front of the plunger 22.

Title: Improvements relating to the amplification of electrical oscillations
IPC: H03F1/54
Filed: 1934-09-13
Abstract: 432,618. Valve amplifying circuits. NUMANS, J. J., 45, Van Soutelandelaan, The Hague. Sept. 13, 1934, No. 26339. Convention date, Sept. 13, 1933. [Class 40 (v)] To prevent distortion, in an L.F. amplifier particularly of the mains-driven type, where the resistance of the input circuit causes a shift in grid-bias potential when grid current flows, the grid potentiometer is shunted by a neon lamp or auxiliary valve designed to maintain the biassing-potential constant. As shown in Fig. 3, the potentiometer 8 supplying grid-bias to the main amplifier 2 is shunted by a voltage-control valve 9. The grid-bias on that valve is regulated by a resistance 11 in the anode-cathode circuit in such a manner that the voltage across the potentiometer tappings is kept constant irrespective of changes in the grid current taken by the main amplifier 2. The curve A in Fig. 5 shows the normal increase of grid-bias voltage Vg1 across the potentiometer 8 as the amplifier grid-current Igl rises ; curve B shows the improvement obtained by shunting a suitably-biassed valve across 8 ; whilst curve C shows the straightline effect produced by a valve having a biassing- resistance 11 as in Fig. 3. Fig. 4 shows the invention applied to a push-pull amplifier of the kind described in Specification 298,169, [Class 40 (v)]. The grid potentials of the amplifiers 2, 2 are adjusted by a potentiometer 15 and resistance 14. The voltage-control valves 12, 13 are biassed from a no-load source E, and serve to offset the effect of grid current taken by the main amplifiers.

Title: Automatic trap nest
IPC: A01K31/16
Filed: 1933-09-26
Abstract: 422,502. Trap-nests. THORLIN, W. J., 13, Hill Farm Road, North Kensington, London. Sept. 26, 1933, No. 26443. [Class 5 (ii)] A bob-wire A<1> free to swing inwards or outwards is pivoted at the top of the entrance opening and carries a sliding shutter S which normally rests on cranked portions of the wire. Pins T, projecting from the ends of the shutter S, normally register with notches U in the front wall of the trap but are prevented from passing outwardly through such notches by pivoted flaps X : other notches V are provided at a higher elevation through which the pins may pass to the outside of the nest. A bird, entering, pushes the bobwire inwards and steps on a platform C mounted on a pivot C<2>: should the bird be a non-layer it can return through the entrance by pushing up the sliding shutter S until the pins T can pass through the notches V when the bobwire can swing outwards. Should an egg be laid however it rolls through an opening D and falls on to a cup E this cup descending through the weight and rocking two levers G<1>, G', the one lever G<1>, lifting a locking arm B1 that engages and holds the bobwire in the closed position and the other G<2>, moving an arm J out of the path of a sliding shutter K<1> this shutter falling and opening a passage at the rear of the trap. Until an egg is laid the bobwire is prevented from being pressed inwardly by a second bird by a stop-piece C<1> that is raised into the path of the wire by the rocking of the platform C as the bird settles itself to lay. The egg rolls from the tray E into a drawer O. The bird having laid the egg, passes out through the aperture left open by the fall of the shutter K<1> and steps on a pivoted platform L. This platform, on being depressed by the weight of the bird, actuates a lever M which raises the shutter K1 to its closing position again, the stop arm J then falling back into position to maintain the shutter in this position and the levers G', G<2>, taking up their original raised position in which the arm B<1> is withdrawn from its locking position. The platform L, after the bird has stepped into the pen of laying birds, is returned to its original position by a weight N.

Title: Improvements in and relating to electronic relay arrangements for protecting power systems
IPC: H02H3/40
Filed: 1949-10-14
Abstract: 659,610. Protective cut-out systems. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 14, 1949, Nos. 26445 and 26446. Convention dates, Oct.. 14, 1948. [Class 38(v)] [Also in Group XL(c)] An electronic relay arrangement for protecting a power line 2, 4 includes a valve 20 having a control grid 19 supplied with an operating potential in accordance with the instantaneous values of current and voltage in the line, and a suppressor grid 32 supplied with an intermittent operating potential from a peaking transformer 29 controlled by a valve 26 fed by a voltage dependent on the system voltage, the valve 20 being rendered conductive when the potentials are applied simultaneously to the grids. A voltage is induced in transformer secondary 15 and is compared with the voltage induced in the secondary 8 of a combined transformer and reactor 6 fed from a current transformer 1 in the line. The arrangement is such that the grid 19 is biassed negative when the voltage in 15 exceeds that in 8, but when the latter is equal to or greater than (i.e. on fault) that in 15, the grid 19 is biassed positive to render valve 20 conductive. The phase of the voltage in 8 is shifted by means of a condenser 10 and variable resistor 9. The voltage induced in secondary 24 renders the valve 26 conductive once every cycle and thus an impulse from transformer 29 is applied to grid 32 once every cycle. When both grids 19, 32 are biassed positive, valve 20 fires and drives negative the cathode of a gas-filled valve 34, which thereupon fires to energize a coil 35 which closes a contact 37 in the trip circuit of circuit breaker 40. In the arrangement shown, the grid 25 of valve 26 is supplied with the vector sum of the voltage in secondary 24 and the voltage across a condenser 48 connected to a secondary 46 of transformer 6, so that the impulse from the peaking transformer is displaced in phase relatively to the voltage applied to grid 19. This secondary 46 may be omitted, Fig. 1 (not shown), in which case the impulse occurs at the maximum of the line voltage. The harmonic component of the voltage in secondary 8 is damped by means of a condenser 13 connected across a secondary 12 of transformer 6. The primary 28 of transformer 29 is connected in the plate circuit of valve 26 and is tuned by a condenser 33 so that a peak voltage is maintained for several cycles after a fault occurs. The valve 26 is arranged to saturate in response to a small change in its grid voltage, so that the voltage peaks applied to grid 32 are of substantially constant value. The grid 19 may alternatively be supplied with a voltage derived by comparing two voltages dependent, e.g. on the currents at each end of a section, or on either side of an electrical apparatus. The theory underlying the invention is set out in detail in the Specification. Specification 548,931 is referred to.
