Title: Improvements in or relating to calculating devices particularly applicable to mean speed indicators
IPC: G06G3/00
Filed: 1929-09-12
Abstract: 340,013. Wendling, H. Sept. 12, 1929. Logarithmic calculators.-Apparatus for calculating products and quotients of simple factors or of factors raised to a power incorporates two toothed cams interengaging to give a logarithmic conversion. The apparatus shown in Fig. 2 for calculating a quotient, in this case mean speed, comprises a cam H1 driven from a flexible drive R<1>, whose angular rotation is proportional to the magnitude of one factor, through the successive 10 to 1 gearing trains D1, J1 &c. the wheels D1, &c. gearing with wheels F1 &c., fast on the shaft E and toothed over <1>/6th of their circumference, the toothing on each of these wheels being displaced angularly by that amount with respect to that in the preceding wheel, and the circumference of the wheels F1 &c. being 5.4 times that of the wheels D1 &c., in order that, the factor varying from 1 to 10, the wheel D1 makes <9>/10 of a turn engaging all the teeth on the wheel F1 and rotating the shaft E 1/6th of a turn, and the factor varying from 10 to 100, the wheel D2 makes <9>/10ths of a turn and the shaft E 1/6th of a turn and so on. The cam H1 is rotated from the shaft E through the gear train G multiplying the movement by six and engages with the toothed cam H1<1>, giving a logarithmic conversion. The cam H1 makes a complete revolution corresponding to the completion of each decimal place effected by the wheels F1, F2 in succession. The cams H2, H2<1> are driven from a shaft, rotating through an angle proportional to the other factor, through gearing similar to that driving the cams H1 and H1<1>. The rotations of the cams H1<1>, H2' are transferred to a differential with sun wheels V1, V2, planet wheels W, W<1>, and frame S giving a rotation equal to half the difference of the rotation of the cams H1<1>, H2<1> which is thus a measure of the quotient of the factors. The simultaneous gearing of the cams H1, and H1<1> at the two points h and h<1>, Fig. 1, is facilitated by a pivoted sector I urged by the spring i<1> against an abutment i on the cam H1. The return to zero is effected by causing the shaft E to complete the rotation commenced, a lag of <1>/54th of a turn of the shaft being provided (the wheel F1 carrying supplementary teeth on <1>/54th of its circumference) to eliminate the initial error due to the logarithm of 0 not being mechanically translatable.

Title: A testing apparatus for comparing high tension currents
IPC: F02P17/00
Filed: 1937-10-16
Abstract: 490,635. Detecting faults; testing ignition. CUNNELL. R. J. Oct. 16, 1937, No. 28183. [Class 37] [Also in Group XXVII] A testing device, particularly for the ignition system of an automobile internal - combustion engine, comprises a multispark gap assembly consisting of at least three electrodes 1, 2, 3 of which the electrode 3 is common and adjustable in a support 4 to form two or more mutually adjustable spark gaps 5, 6. This assembly is combined with a two-pole-two-way switch 14, which, when thrown to the left, Fig. 2, connects the primary of a standard induction coil 13 in series with an ammeter 17 and an interrupter 11 driven by a motor 12, across the low tension supply, for example, from the automobile, at terminals 18, 19, whereby the high tension winding of coil 13 produces a spark across the gap 5. By throwing switch 14 to the right, the low tension winding of the ignition or other coil under test connected across terminals 20, 21, is connected in series with the contact breaker 11 and ammeter 17 across the supply 18, 19. The high tension side of the coil under test is connected to terminal 25 and a spark produced across the gap 6 by this coil may readily be compared with the spark across gap 5 caused by the standard coil 13 by moving switch 14 from one position to the other. The speed of the contact breaker may be varied by altering the motor speed through a rheostat 28 and regulator 29 which may be short circuited at 30. A regulating resistance 31 in the primary circuit of coil 13 may also be cut out by a switch 32. Condenser tests are made by connecting the condenser to be tested between terminals 22, 23 and throwing a two-way switch 16 firstly to the right-hand position and then to the left, thereby connecting a master condenser 15 and then the condenser under test successively across the interrupter contacts 11. The switch 14 being in the left-hand position, sparks are produced across the gap 5 by the coil 13 and the alteration in the sparks as the switch 16 is operated gives an indication of the state of the test condenser. The amount of sparking at the interrupter contacts 11 gives an additional indication as to the condition of the test condenser. Insulation tests are effected by test prods connected to terminals 18, 24, with the switch 14 in the left-hand position, defective insulation being indicated by sparks passing between one of the prods and the article under test when the other prod is connected to the metallic parts of the test article. The behaviour of the ammeter 17 gives an additional comparison when testing ignition coils and is provided with terminals 39 for connecting it to the contact breaker of the ignition system under test for comparing the latter with the interrupter 11. The apparatus is mounted on base panels 7, 8, in a box 9 provided with a hinged lid 10, and a volt meter 40 is provided for voltage tests. Three or more spark gaps and further master induction coils may be provided with addition switching means to accommodate test coils requiring different voltages.

The roller 2 is either thicker at the middle or at the ends and may be formed of removable elements 4 spaced along a boss 3 by tie bolts 7. The die 8 is of a shape conforming to the roller 2 and is formed from a stack of laminations. Holddown rollers 9 movable through the die 8 independently of the die continue to hold the plate 5 against roller 2 when the die 8 is withdrawn. The plate 5 is fed forward by rotating the roller 2.

A hose 2 of rubber or other elastic material is secured at either end to the shaft 1 by a spring ring 7 clamped between an abutment 8 and a clamp ring 10. Air under pressure is supplied to the space 14 between the hose and shaft 1 through bores 12 and 13 and a valve 17. The hose 2 is expanded by the compressed air, such that the bars 22 bow outwardly to grip a cardboard tube 23. In a modification, the shell 3 may comprise a plurality of separate bars welded together at their ends. Alternatively, separate bars may be mounted at their ends in dovetail slots to permit axially sliding movement of the ends durmg bowing. Compressed air may be supplied by a hand pump. In a further modification, the hose 2 is replaced by a double-walled bag, preferably of rubber, connected to a tube supplying compressed air.

Abstract: 692,274. Respiratory appliances. DRAGER, O. H. Nov. 20, 1950 [March 24, 1949], No. 28374/50. Class 81 (ii). [Also in Group XXVIII] An air pump for artificial respiration apparatus comprises an air bellows 1 fitted with super-pressure and negative pressure valves 3, 4 and a nipple 2 adapted to be connected through 'a flexible pipe with the respiration apparatus, and actuatec through a rod 5 by a double acting hydraulic motor 6 7. Hydraulic fluid is sup plied by an electrically operated pump 13 alternately to each end of the motor cylinder through a change-over valve 10 actuated by abutments on the rod 5 or on the bellows. An adjustable by-pass valve 15 controls the delivery of the pump 13 and hence the reciprocation frequency of the bellows, and a further adjustable valve 17 controls a second bypass from one side of the motor cylinder to the suction side of the pump 13 for varying the relative duration of the pressure and suction phases of the bellows. The valves 15, 17 may be coupled for operating in unison so that the frequency is not varied when the phase ratio is adjusted and vice versa. The motor may alternatively be fed from a supply main. The bellows may be operated manually by a bell-crank lever 18 in the event of power failure, the change-over valve 10 being then adjusted to connect the ends of the motor cylinder together.
