Title: Calculating Device
Inventor: HOFFMEISTER ERNEST WALTER
IPC: G06G1/02
Filed: 1967-05-19
Abstract: 1,195,253. Calculating device. E. W. HOFFMEISTER. 19 May, 1967 [25 July, 1966], No. 23328/67. Heading G4B. A calculating device includes two endless tapes A, B bearing logarithmic scabs, an optical projector for projecting the image of a selected portion of each tape in a side-by-side relationship on a screen 20, means for moving each tape independently of the other, and means for connecting the drive to each tape so that the tapes may be moved in unison. Each tape passes over a toothed wheel 30 or 32 secured to a shaft 22 or 24 rotated by a cranked handle 110a or 110b. Fine adjustment of the tapes is achieved by rotating a knob 112a or 112b driving their respective shafts through reduction gearing. Operation of a pull-rod 74 presses a roller 60 against the toothed wheels 30, 32 whereby the tapes may be moved in unison. Brakes 108a, 108b are independently operable by pull-rods 98a, 98b to hold the tapes stationary. Each tape comprises a plurality of side-by-side logarithmic scales marked off in units, tenths, hundredths, and so on, respectively, and is prepared by exposing colour photographic film so that each section of the scales is coloured according to the digit it represents. Decimal-point indicator.-A member wheel 136 rotatably mounted on shaft 24 has pins 140 and 140 projecting from each side, which co-operate with pins 154 and 156 on a wheel 152. The latter is driven by a belt and pulley arrangement on rotation of the shaft 24 whereby the wheel 136 is moved one step each time the datum line on the belt B passes a hairline 21 on the screen. A second member wheel 130 freely rotatable on the shaft 24 is set manually according to the characteristic of a value selected on belt A. The member wheels are held in their selected positions by leaf springs 134, 144.

Filed: 1969-05-09
Abstract: 1,241,090. Electro-physical measurement. ELECTRONIC SENSING PRODUCTS Inc. May 9, 1969, No.23771/69. Heading G1N. A metal detector comprises tuned coaxial transmitter and receiver coils one of which has a reentrant loop so that there is substantially no coupling and only a small signal is received in the absence of metal. The receiver is preferably so placed, and tuned to the higher side of null, that decrease in inductance due to the presence of metal causes an increase in signal. The transmitter is energized with audiomodulated R. F. from a "squegging" oscillator and the tuned receiver coil is fed to a multi-stage transistor amplifier with an adjustable threshold and an A.V.C. feedback from the output stage with a delay network to disregard drift. Signal indication is by meter and phones. In an underwater unit the coils, meter and circuitry are housed in a polyester case shrunk over PVC fittings. An earthed shield of parallel wires may be embedded in the bottom of the case.

[Class 135] [Also in Group XXVII] A predetermined ratio between the fuel and air admitted to the cylinder of an engine is automatically maintained by devices responsive respectively to (1) the temperature of the air delivered to the cylinder; (2) the pressure of this air; and (3) atmospheric pressure. Fig. 1. shows one form in which a servomotor piston 53 controls the delivery of a fuel-injection pump according as a pilot valve 49 is adjusted by a capsule 12 connected to a thermostat 14 in the blower outlet, a capsule 27 connected to atmosphere at 28, and an evacuated capsule 31 subjected to the blower outlet pressure admitted at 11 to the casing 10 containing the devices. The blower pressure also acts on the altitude capsule 27, both being connected at 36 to a lever 26 pivoted at 39 to a sliding guide 40, which is also connected by a lever 46 to the servomotor piston 53 and valve 49. The capsule 12 is connected by a lever 21 and link 23 to a pin 24 sliding in a fixed guide 25 and in a slot 38 in the lever 26. The ratio of the volumes of the capsules 31 and 27 equals the ratio of the swept to the unswept volume of the engine cylinder; or the volumes of the capsules may be equal and the leverage of the connections to the rod 35 arranged to give this ratio. In a modification, the invention is applied to apparatus comprising a variabledatum boost control, for example as described in Specification 482,441, [Group XXVII]. Specifications 453,766, 497,380 and 500,149, [all in Group XXVII], also are referred to.

Abstract: 246,757. Lodge-Cottrell, Ltd., (formerly Lodge Fume Co., Ltd.), and Stallard, N., (Metallbank und Metallurgische Ges. Akt.- Ges.). Sept. 23, 1925. Addition to 176,713. Gases, treating electrically.-In a modification of the apparatus described in the parent Specification, the rod 3, which serves as the rapping tool for the electrodes, is operated by crank or equivalent mechanism which periodically releases the rod in the vicinity of the top of its stroke, in such a manner that the blow against the electrodes to be jarred is caused by the falling of the rod. In the arrangement shown, a crank 6, carried by a rotating shaft having an insulating portion 10 mounted in a leading-in insulator 8, engages a hook 5 at the top of the rod 3, lifts the rod to a certain height and then releases it, thereby allowing it to fall on to the frame 1 carrying the discharge electrodes 2. The striking rods of a number of gas-clearing units may be provided with a common drive, the cranks operating each rod being so arranged that the rods are brought rythmetrically into play one after the other. The rod may work in conjunction with a hammer or like tool, which serves to jar the electrodes, and the rapping arrangements may be applied to the collecting electrodes as well as to the discharge electrodes. The crank mechanism for raising and releasing the rod may be employed in the rapping apparatus described in the parent Specification.
