Abstract: 1,231,347. Cigarette batch feeding apparatus. MASCHINENFABRIK FR. NIEPMANN & CO. 28 May, 1969 [2 July, 1968], No. 26847/69. Heading B8C. Apparatus for feeding a batch of cigarettes to a cigarette-packing machine, comprises a support base 2 beneath the discharge end of a feed hopper 1 which has at least one nozzle 8a on its internal wall directed towards the discharge end of the hopper and is arranged for connection to a supply of compressed gas 9, discharge of which from the, or each, nozzle serves to accelerate the fall of cigarettes within the hopper. As shown, a number of shoots 3 extend between the front and back plates la, 1b of the hopper 1, the base-plate 2 supporting each batch of cigarettes as it is pushed, by a reciprocating ejector 4, into an arbor 5. After receiving a batch of cigarettes the arbor 5 is lowered so that a flight 7a on a conveyer chain 7 moves the batch out of the arbor and along a packer feed track 6. A batch of cigarettes falls squarely upon the base-plate 2 as the ejector 4 is completely withdrawn from the hopper and an L-shaped retainer plate 10 is simultaneously swung up clear of the shoots 3, the fall of the cigarettes being accelerated by supplying, at the same time, a brief supply of compressed air through the nozzles 8a. A compressed-air pipe 8, fitted with a valve, not shown, and having a series of nozzles 8a, is fitted to the front and back plates la, 1b of the shoot, the valve being opened briefly, e.g. by rotating cam mechanism, while the ejector is in the retracted position.

An electrostatic loudspeaker element includes two perforated spaced apart plates 11, 12 of rigid insulating material each including a conductive surface 29, 16 on the side facing away from the other plate which surface is perforated with holes of larger diameter 21 than the holes in the respective plates and a diaphragm 15 of flexible insulating material coated with electrically resistive material secured between said plates. Plates 11, 12 are made either by a printed circuit technique or from a sheet of copper coated epoxy glass laminated. The conductive areas are produced by an etching process and the holes produced by drilling and counterboring or countersinking. The finished plates are encapsulated or varnished at 23 which produces a slight flaring at each hole leading to improved acoustic properties. The diaphragm 15 consists of polyvinyl or polyvinylidene chloride 0À0004 inch thick and is coated with resistive material on both sides to give a resistivity of 1 x 10<SP>7</SP> to 5 x 10<SP>8</SP> ohms/square inch. It is secured to an outer frame and shrunk before cementing to rear spacer member 13 when the outer frame is removed. After assembly the diaphragm is gripped between spacer members 13, 14 around each loudspeaker element and is electrically connected through contact 24. The array of loudspeaker elements may be curved to improve its directional characteristics.

Abstract: 1,256,776. Automatic control of chemical composition. WESTINGHOUSE ELECTRIC CORP. (Fuller Co.). Dec. 10, 1969. No.60308/69. Heading G3R. In a system in which a characteristic of a product is modified by the addition of a chemical, the characteristic of a sample of the modified product is varied by further addition of the same chemical to detect a minimum or maximum and the difference between this and the characteristic of the modified product is maintained constant by utilizing it to control the chemical addition. In Fig. 3, a sample of water treated with lime is withdrawn from a water softener (not shown) by a pump 16 and passed through a conductivity cell 1 the output of which, by means of a follow-up servomotor (not shown), rotates a shaft 4 carrying a pair of arms 37, 38 to a position corresponding to the conductivity. A programmer 23 periodically opens a valve 19 so that an increasing supply of untreated water is mixed with the sample in a coil 20. This causes the conductivity to vary through a minimum and arms 37, 38 to be set to a datum clockwise position by virtue of a stop and slipping clutch (not shown). Then, when the programmer closes valve 19, arms 37, 38 move to a position corresponding to the conductivity of the sample relative to the minimum. Magnets 44, 45 at the ends of arms 37, 38 control switches 31, 30 so that, if the relative conductivity is above or below predetermined values, a relay 43 or 42 is operated to run a servomotor 40 in the appropriate direction to correct the conductivity by controlling the rate of supply of lime to the water softener. The relative position of arms 37, 38, the position of the limit stop, and the position of switches 30, 31, are adjustable to select desired operating conditions. The specification also refers to control of chemical addition in dependence on measurement of temperature, viscosity, density or pH relative to a minimum or maximum value.

A multi-stage reciprocating compressor comprises a differential area piston 7 arranged to compress gas in two stages in a stepped cylinder 1, the compressed gas being delivered through a conduit 29 and a side port 30 to a cylinder 17 for further compression by a plunger piston 18 attached to the piston 7 and slidable in an annular seal (36), Fig. 2 (not shown). The first stage of compression takes place in the cylinder space above the piston 7 and the second stage in the annular space 25. After final compression gas leaves the cylinder 17 through a spring-loaded poppet valve 31, Fig. 10 (not shown), having a seat substantially the same diameter as the cylinder 17. To accomodate errors in the concentricity between the cylinders, the plunger piston 18 is attached to the piston 7 by means which allow slight lateral movement. In other embodiments a number of the compressors shown are formed in a single unit having a common crank-shaft 5 and cylinders arranged in-line or V formation. When the cylinders are arranged in V formation, Figs. 6, 7, and 8 (not shown) they may be inter-connected in a variety of ways depending on the quantity and pressure of the gas required. An in-line cylinder configuration, Fig. 9 (not shown) has the output from the first and second stages of three cylinders combined for subsequent compression in the final stages of two cylinders followed by compression in the final stage of the remaining cylinder.

The course contour structure of the character is compared with reference structures to determine which reference most closely matches the scanned character. The reference structure represents a group of characters, e.g. 5, 6, 9, which have the same coarse contour structure. To determine which of the characters in the group most closely matches the scanned character the store is read to provide signals representing parts of the contours of the character, these parts being sufficient to identify the character. The signals may represent the ratio ho2 : ho1 Fig. 5a (part shown), for example. The probability of the identification being correct is noted at each stage in the recognition. If the probability reaches a certain level it is assumed that the character is correctly identified and further investigation is stopped.
