Title: Improvements in or relating to book-keeping machines
IPC: G06C21/00
Filed: 1961-02-02
Abstract: 913,448. Typewriters &c. KIENZLE APPARATE G.m.b.H. Feb. 2, 1961 [Feb. 27, 1960], No. 3974/61. Class 100 (4). [Also in Group XIX] A tabulating column control arrangement for a book-keeping machine allows any desired programme to be carried out by the control of column stops actuated by electromagnets mounted on the carriage. The control bridge 1 of a book-keeping carriage mounts column stops 15 which can be projected to an operative position by electromagnets 4. In operation upon selection of the desired stop 15 by manually operable contacts or under the control of a punched card or other programme-control device its electromagnet 4 operates and through linkage 7-14 the stop 15 is lowered. A corresponding blocking lever 20 is then swung by its spring 21 to hold the stop 15 operated when its magnet 4 is de-energized. A tabulating stoplever 49 is now momentarily released from a stop 52 and the carriage moves from its initial position until arrested by the operated stop 15. This movement allows a lever 44 to drop off a cam 46 and through a linkage to pivot a rod 32 so that a drive pawl 30 comes opposite a lug 29 of a pawl 28 so that on return of the carriage a slider 24 is moved and by a notch 25 a pin 22 is forced upwards to pivot the blocking lever 20 to allow the stop 15 to restore. During this action the pawl 28 is slowly pivoted so that its lug 29 becomes disengaged and a spring 59 can restore the slider 24 while the return of the carriage by its cam 46 restores the lever 44 and all parts thus reach their initial positions. In order to position the carriage in each column for totalling without returning it to its initial position between each column as in normal operation a second programme is brought into effect automatically or manually. A shaft 53 is turned and by a lever 58 moves the slider 24 so that the pins 14 are forced down oblique surfaces 62<SP>1</SP> to cause each pin 15 to be projected.

Abstract: 234,417. Kilchling, K. Feb. 12, 1925. Gravity, measuring force of. -In a torsion balance for detecting and measuring variations in the strength of the gravitational field, a slow, uniform rotation is impacted to the upper end of the torsion filament, the variations in the field being measured by the varying rate of rotation of the suspended element. The Figure shows an E÷tv÷s balance comprising a torsion filament h from which is suspended a rod i carrying equal weights k, l. the upper end of the f.lament being attached to a spindle d which is rotated uniformly by clockwork c. The variations in the speed of rotation of the rod i may be indicated by means of a pointer g suspended by filaments e, f from the clockwork and rotating uniformly therewith; this pointer may be formed as a casing protecting the whole suspended system from air currents in the casing a. Alternatively the indications may be obtained optically or photographically. The measurements may be facilitated by using two instruments disposed at 180‹ tc each other, so as to be equally and oppositely affected by variations in the gravitational field.

Title: Particle-size spectrometers
IPC: G01N21/53
Filed: 1973-01-26
Abstract: 1422197 Photo-electric particle size measurement SARTORIUS-MEMBRANFILTER GmbH 26 Jan 1973 [28 Jan 1972] 4057/73 Heading G1A The number of particles per unit volume and/or size distribution of particles in a flowing carrier fluid is determined by illuminating the fluid and analyzing the light scattered by the particles over an angle whose minimum value is near 180 degrees. A beam of light and a stream of the fluid are arranged to intersect to form a centre of scattered light within a chamber having an inner surface, at least a part of which is arcuate and arranged to collect and direct scattered light to a photomultiplier, the part of the surface extending to points adjacent to the light beam both in front of and behind the centre of scattered light. Fig. 1 shows how the fluid is illuminated; light from a print source 2 is focused to a line by lenses 4, 14 and 20, the focus being in a stream of carrier fluid passing from capillary tube 32 into collection tube 37. The light passes through apertures in screens  6, 22, 24, and also through holes 28, 29 before being absorbed in horn 30. Carrier fluid is passed through a capillary tube 33 to guide the particle containing stream into the collection tube, and is also passed into apertures 40 for collection by tube 37. The tube 37 is connected to a pump to maintain the apparatus below atmospheric pressure, and the particle concentration is such that they pass through the light beam one at a time. Light scattered from the particles is passed to a photomultiplier, and the resulting signal may either be displayed to give the number of particles in each of several ranges of size, or may be integrated to give the number of particles per unit volume of carrier fluid. The particles may be conveyed by a gaseous or liquid carrier medium. In Fig. 1 the section taken is such that the arcuate surface and photomultiplier are not shown. Fig. 4 shows a modification in which light scattered from the particles is collected over a solid angle of substantially 4#. The chamber 8 here has a spherical form 8a and has a matt white inner surface. Light is conveyed to the particle stream 10 by a tube 49 whose outer surface is reflective. The scattered light is measured by a photo-multiplier 46 connected to the sphere via aperture 44, screen 48 preventing scattered light passing directly from the particles to that aperture. In Fig. 5 a set of light guides are used to convey the light from surface 54 to photo-multiplier 46; these guides lie in a common plane so that the scattered light is measured over an arc rather than a solid angle. Mirrors 56, 57, 62 direct scattered light on to surface 54, the walls of the chamber 8b being matt black. Screen 60, also matt black, prevents light diffracted at mirror 56 reaching the guides.
