Abstract: 275,836. Clarke, A. A. Nov. 12, 1926. Planing. - A portable machine for surface smoothing, &c., woodwork, floors, &c. consists of a one-piece casing hinged at 20 to a base 10 and having chambers for a drum 44 carrying cutters, for an electric motor 55, and for a fan 60, and ducts 26<a>, 26<c> for the dust &c. which passes to an outlet 27<a>. The casing and the base 10 are slotted to allow the drum 44 to project to engage the work, and the casing is adjusted about the hinge by a screw 18 engaging a threaded handle 37; a second handle 32 also is provided. The drum runs on ball bearings 42 on a snindle 41, the ends of which are mounted in bushes 39, 40 in the casing, the bush 40 carrying the spindle eccentrically whereby the end of the spindle may be raised or lowered. A tube 46 forms a lubricant housing and prevents access of dust to the bearing from the inside, the outside being protected by gaskets 47. A flexible apron 38 is attached to the casing to confine dust to the duct 26<a>. The motor armature and the fan 60 are carried by a shaft 57 running in ball bearings 58, 59, and the shaft drives the drum through gearing 61 carired in a housing 28. For use in smoothing floors, a carriage 75, Fig. 10, is secured by screws 80 to the base 10, two independent wheels being fitted on the carriage, which also has a handle 76. Air is drawn trough the motor casing by the fan through opening 25<a>, 26<d>. The surface speed of the drum is arranged to lie between 2600 and 3500 feet per minute; the drum diameter is six inches, or less, and the weight of the tool is 40 pounds or less.

Abstract: Arsines of the general formula <FORM:0661284/IV (b)/1> wherein R represents a methylene or an o-phenylene radical, are prepared by heating carbasone oxide with thiosalicylic acid or thioglycollic acid in aqueous alkaline solution and acidifying the reaction mixture. The reactants may be employed in the ratio of about 1 mol. of carbasone oxide and 2 mols. of the required acid.  The aqueous solution may be an aqueous solution of a metal hydroxide, a metal carbonate or a metal bicarbonate.  Strong organic or mineral acids can be used to acidify the reaction mixture.  Salts of the arsine are prepared by treating the arsine with an equivalent amount of an alkali and the sodium, potassium, calcium, ammonium and substituted ammonium salts are mentioned. Two examples are given.

Title: A process for the recovery of aluminium and fluorine compounds from the worn out linings of the electric furnaces employed for the production of aluminium
IPC: C25C3/06
Filed: 1937-10-21
Abstract: Worn out carbon linings of electric furnaces employed in the electrolytic production of aluminium are extracted with a dilute solution of a mineral acid or of an aluminium salt of a mineral acid or a mixture of both, and the extract is worked up into alkali-aluminium fluorine salts, such as cryolite or sodium chiolite, or sodium potassium cryolite, by the addition, for example, of sodium chloride and hydrofluoric acid, or of potassium sulphate and hydrofluoric acid.  The mineral acid, e.g. hydrochloric acid, liberated during the precipitation of the cryolite &c. is employed either for producing the dilute aluminium salt solution, or for the direct extraction of the furnace lining. In examples, the ground furnace lining is extracted at 50-100 DEG  C. with (1) aluminium chloride solution containing 4,1 per cent Al2O3 in the presence of a small quantity of hydrochloric acid, (2) 10 per cent hydrochloric acid, (3) 25 per cent sulphuric acid.

Title: Signal detection system
IPC: G11B20/14
Filed: 1967-06-22
Abstract: 1,121,340. Transistor pulse circuits. INTERNATIONAL BUSINESS MACHINES CORP. 22 June, 1967 [24 June, 1966], No. 28797/67. Heading H3T. [Also in Division G4] Binary signals 15, of the kind in which a data pulse is present or absent between successive clock pulses depending on the bit value, are detected by using the signals to synchronize a ramp signal generator VFO arranged to operate at twice the clock pulse repetition frequency, a gating signal 22 being issued when the ramp voltage lies between predetermined limits. The gating signal 22 is produced by ANDing the outputs of positive and negative threshold devices which are fed with the ramps at 25 and the thresholds of which are adjustable by respective potentiometers, P1, P2. The gating signal 22 is fed to a further AND gate 14 together with the input binary signals 15 and one output of a trigger 12. This trigger is switched at each ramp fly-back, and is preset to a state depending on whether the data or clock pulses in the input binary signals are required to emerge from the further AND gate 14. The ramp signal generator VFO is synchronized so that the input binary signal pulses occur ideally at the ramp mid-points, and could be as in Specification 902,163 which is referred to. As a modification, the input pulses could occur at ramp flybacks, the trigger 12 switching at ramp mid-points.

Abstract: 983,305. Dish-washing machines. ELECTROLUX A.B. Aug. 10, 1961 [Sept. 21, 1960], No. 28889/61. Addition to 918,412. Heading A4F. The dish-washing machine of the parent Specification is provided with a liquid-level-regulating member between the pump inlet and the discharge valve. For "pre-dish-washing" flushing the lever 37 is set as shown in Fig. 6 the water level being regulated by member 44, sump 23 thus being kept full so that pump 32 may operate satisfactorily with a comparitively small quantity of water: a continuous flow being maintained even with low mains pressure. For actual "dish-washing" lever 37 is moved to its far left position (Fig. 5, not shown) closing outlet 35 by means of disc 36. The washing liquid level is then governed by overflow drain 39 which permits a larger quantity of liquid to be retained in the machine for re-circulation. After washing is completed lever 37 is again set as shown in Fig. 6 and rinsing carried out with fresh water. The machine is drained after rinsing by moving lever 37 to its far right position (Fig. 7, not shown) when outlet 35 is open and member 44 is disengaged from the walls of sump 23.

Title: Unidirectional voltage generator
IPC: H02M3/04
Filed: 1945-10-31
Abstract: 602,562. Condenser charging circuits. TRIGGS, W. W. (Farnsworth Television & Radio Corporation). Oct. 31, 1945, No. 28958. [Classes 38 (ii) and 38 (iv)] In an arrangement for producing a D.C. voltage from a pulse source, a voltage multiplier has its high voltage terminals connected across a plurality of impedances in series, and an intermediate terminal coupled through a filter network to the pulse source and to the junction of two of the impedances. A positive pulse is generated at the anode of blocking oscillator 11 when the valve is cut off by regenerative action, and charges capacitor 22 through diode 26. When the pulse ceases, diode 26 is cut off and the potential at the cathode of diode 29 swings negative by an amount substantially equal to the pulse amplitude. Capacitor 22 discharges through the relatively low resistor 21 between pulses and filter 23, 25 smooths the output at terminal 24. Diode 29 conducts during the negative swing at the cathode to charge capacitor 27 to the peak level of capacitor 22 and since resistor 19 is relatively high, the potential at terminal 28 remains substantially at this level.

Abstract: 502,197. Time-alarm signals. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., and WALFORD, H. N. Oct. 23, 1937, No. 29014. [Class 118 (ii)] In an electric clock provided with alarm mechanism operated by the leakage flux from the stator of the motor, a pawl l is set by the dial n to the time at which the alarm is to sound, a freely mounted member h being rotated from the clock mechanism through a lost-motion device such as a pin and slot on wheels t, u. Upon the recess m coming opposite pawl l, the member h is displaced axially by spring c acting through bell-crank lever d bearing on a coned portion g of the member h, the stray flux of the stator of the clock mechanism contained in casing a causing plate b to vibrate to give the alarm. In order to silence the alarm, a spring-loaded pawl, actuated by a push-button (not shown) is arranged to rotate ratchet wheel j, pawl riding up the incline m, the clock mechanism being unaffected due to the lost-motion device. In order permanently to silence the alarm, a lever z may be moved over a projection 2 to maintain the vibrator b against the casing a. As an alternative form of vibrator, Fig. 4 (not shown), the plate b is flat, but of spring material, fastened to the clock casing, the spring c then being unnecessary.
