Abstract: 1373108 Hydrocyclones BANYASZATI KUTATO INTEZET 3 Dec 1971 [4 Dec 1970] 56275/71 Heading B2P In a hydrocyclone having a separator body 1, 2 of circular cross-section, a feed pipe 4, an outlet pipe 6 and an adjustable drain opening 5, the feed pipe is so shaped that in use a liquid mixture or suspension fed through it is subjected to a uniformly increasing centrifugal force, the feed pipe axis extending in a plane perpendicular to the longitudinal axis of the hydrocyclone and its cross-section being generally rectangular in the region where it debouches into the separator body. The feed pipe is generally shaped to follow a curve of an order of osculation higher than two, the curve osculating with the circle of the crosssection of the separator body. As defined in the Specification "osculation of order n" between two curves means that at their common point all the differential coefficients of the two curves up to the nth are equal, that the curves are capable of differentiation at least (n+ 1) times, but their (n + 1) differentials are not equal at said common point. A rubber liner 3 is secured, e.g. by sticking to the iner surfaces of the cyclone body and feed pipe. The size of the opening 5 may be altered by the variable compression of an elastic block 11, or an elastic ring 7, Fig. 1 (not shown) by means of a nut 9. The cross-sectional shape of the feed pipe 4 varies from circular at v-v to the shapes illustrated in Figs. 6 and 8 at vi-vi and viii-viii respectively.

Abstract: 1,175,116. Control of A.C. motors. BRUSH ELECTRICAL ENG. CO. Ltd. 27 Feb., 1968 [16 Dec., 1967], No. 57238/67. Heading H2J. For stable operation of an A.C. motor M which is supplied through a variable frequency inverter P from a D.C. source S, a link-current signal developed across resistor R is applied to potentiometer E associated with differentiating amplifier D. The frequency of operation of the inverter is a linear function of the frequency of pulses derived from an oscillator O whose input current is controlled by transistor T. When the rate of change of link-current becomes positive, a current passes through resistor R 2  to reduce the input to the oscillator and so decrease the frequency of the inverter. When the rate of change of link-current is negative, the output voltage of amplifier D exceeds a bias potential and the current through the resistor R 2  is reversed. This increases the input to the oscillator whereby the frequency of operation of the inverter is increased.

Title: Printer
IPC: B41J19/18
Filed: 1973-12-13
Abstract: 1424380 Automatic positioning INTERNATIONAL BUSINESS MACHINES CORP 13 Dec 1973 [26 Dec 1972] 57882/73 Heading G3N [Also in Division B6] A serial printer has a document support (cylindrical platen 13) and a printing mechanism (golfball 11) which are relatively movable linewise and characterwise. Sensors 43, 54 detect respectively rotational movement of the platen 13 and lead screw 17. Thus the character and line position of the printer is compared with character and line position data specified by manual input to the panel 60. A discrepancy between the actual position and the specified position is then remedied by the control circuit actuating motor 50 and line feed mechanism. As shown the panel 60 has rows 71 and columns 77 of conductive bands. A membrane 69 has holes 63b corresponding to each intersection of the bands 71, 77. To specify a particular character and line position probe 64 is inserted in the selected hole 63b. Thus two circuits are closed as one of the bands 71 is pressed against plating 73 and one of the bands 77 against plating 75. Encoders 81, 91 translate these circuit closures into binary code. A switch within the probe 64 is closed when it is pressed into a hole 63b. This switch closure gates the input to registers 83, 93. Comparison circuits 85, 95 compare the output of the registers 85, 95 and the coded output of the sensors 43, 54. Depending on the discrepancy, directional commands issue to feed 40 and motor 50. When the desired and actual positions coincide, the gates 84, 94 output to stop the motor 50 and feed 40 and actuate a detent 51 on the ratchet 52.

Title: Apparatus for labelling articles
IPC: B65C9/40
Filed: 1968-12-11
Abstract: 1,246,840. Labelling machines. NEW JERSEY MACHINE CORP. 11 Dec., 1968 [13 Dec., 1967], No. 58941/68. Heading B8F. The labelling machine described in Specification 1,178,902 is provided with means for detecting articles having labels which are incorrectly positioned or missing, or to which an incorrect label has been applied. As shown each label is provided with dots of magnetic ink 30, 31 adjacent two opposite sides, and a code marking 33 in magnetic ink adjacent a third side. As each pair of articles leaves the labelling machine, a pair of appropriately spaced detector heads 55 (which are mounted on a reciprocating beam 50 which also carries presser blocks for firmly attaching the labels to the articles) come into engagement with the labels on the pair of articles. Each detector head has means for sensing all the magnetized markings provided on each label. If the label is correctly positioned on an article magnetic detectors on the head 55 exactly register with the magnetic ink dots, and electric pulses are created which are transmitted to a detector chassis 60 which accepts pulses from both heads. When pulses are not received from one of the heads, a signal is supplied to a solenoid-operated -valve of an air cylinder unit 65, the piston-rod of which acts via racks and pinions 67, 68 and 70, 71 to pivot gates 74 about pins 75 and thus push the detected article on to a reject table 80. If the correct code markings 33 are missing from a label the article will be rejected in similar fashion. Instead of having the detector heads constructed to sense magnetic markings, they could sense non-magnetic ink markings or holes in the label or make optical readings on given portions of the label. They could also be constructed to detect the location of the labels by optically scanning the edges of the labels. In addition to the reject gates 74, an audible alarm could be sounded, or the machine stopped. It is also possible to arrange for the machine to be stopped if a given number of reject signals are received in a given period.

Abstract: 1442995 Multi-cell storage battery ELECTRIC POWER STORAGE Ltd 14 Dec 1973 [21 Dec 1972] 59094/72 Heading H1B A multi-cell lead-acid battery comprises a case formed with intercell partitions 11 having holes 15 for intercell connectors (not shown). The partitions 11 and case end walls 12 have ridges 16 with slots 14 to receive lintels 10, there being a pair of lintels for each cell. The lintels 10 are cemented in the slots 14 and to the ease lid (not shown) whereby air is trapped in the two compartments formed in each cell by the lid, case side wall 13, partition 11 or end wall 12, lintels, and the electrolyte surface, which extends above the lower edges of the lintels. The intercell connectors are situated in these airfilled compartments and are normally above the electrolyte level so that should the battery be moved to cause slopping of the electrolyte the trapped volume of air prevents entry of electrolyte into the compartments and the connectors are not flooded. In modifications (Figs. 2- 4, not shown) the upper edges of the partitions are slotted and the lintels extend across all the cells so that only two lintels are required.

A stray A.C. field produced by the human operator induces in the knob a voltage which is amplified and detected 34, Fig. 5, by transistors Tr1 Tr2 to produce a control voltage at Tr2 emitter which, for example, turns on a FET 1 to earth a point P1 in the A.F.C. loop. The knob, Fig. 4, has two conductive portions 28, 29 connected respectively to terminals 32, 33 by way of bearings 23, 24. These knob portions are connected to separate detector circuits (34a, 34b, Fig. 10, not shown) each similar to the Fig. 5 detector to control separate F.E.T.s (1, 2) which shunt apart and the whole of the A.F.C. signal respectively, so that partial or complete disabling of the A.F.C. is possible by touching one part of the knob or the other. Alternatively (Fig. 6, not shown) a muting circuit (51) is made operative to suppress interstation noise during tuning by using the detector (34) output to turn on a F.E.T. (2); and a two-level muting circuit (Fig. 7, not shown) responds to which part of the two-part knob is touched. Another muting circuit (Figs. 9, 12, not shown) is enabled to operate by the turning on of a transistor (TR4) in response to either detection circuit (34a, 34b) producing an output, and a variable gain muting signal circuit (51a) adopts one of three different gains according to whether one or the other or both of the knob portions is handled. Thus one of-three possible signal levels can be selected at which muting is stopped by conduction of a transistor (TR5) in response to the rectified output of the variable gain circuit (51a). Both A.F.C. and muting circuits may be controlled (Fig. 8, not shown) by respective knob portions.
