Abstract: 816,405. Vibrators for mixing. FLEXIBLE DRIVES (GILMANS) Ltd., and WALKER, D. W. R. Aug. 20, 1957 [Aug. 24, 1956], No. 25903/56. Class 86 [Also in Group XXIV] In a rotary vibrator, particularly for consolidating a plastic mass such as concrete at a vibrational frequency higher than the rotational speed, an inertia sleeve 10, Fig. 4, guidedfor radial movement in a tubular casing 1 is oscillated by a cam-shaped inner member 7 rotating coaxially in the casing I in upper and lower bearings 5, 6, Fig. 2. As shown the member 7 is driven by a flexible shaft 4 and is in the form of a three-lobed cam shaped to maintain constant engagement with two pairs of rollers 17 mounted on pins 18 in the sleeve 10. Alternatively the member 7 may comprise a five-lobed cam. In order to guide the sleeve 10 for radial movement upper and lower diametrical slots 11 therein engage tongues 12 on rings 13, 14 rigidly keyed in the casing 1. The casing 1 is provided externally with fins 19 at right angles to the plane of oscillation. In modifications the inner member 7 is flat and the sleeve 10 is replaced by an inertia body which is radially slidable thereon and which is oscillated by cam lobes on the inner surface of the surrounding casing. Either the casing or the inner member may then be rotated. If the vibrator is to be applied to the outside of a container, rather than be inserted in a plastic mass, then the casing may be apertured to facilitate cooling.

Title: Improvements relating to hydraulic stabilizing arrangements applicable to steam turbines
IPC: F01D17/26
Filed: 1952-10-16
Abstract: 714,023. Fluid-pressure servomotor-control systems. GENERAL ELECTRIC CO. Oct. 16, 1952 [Oct. 17, 1951], No. 26004/52. Class 135 A hydraulic stabilizing device for a hydraulic servo-operated pressure regulator controlling the steam supply from a boiler 2 to the shaft glands 3a of a steam turbine 3, comprises a first variable volume chamber 17 constituted by bellows 16, 18 housed in a casing 11 and responsive to the pressure at the glands through a pipe 13, and a second variable volume chamber 26 housed in a reservoir 28 and connected by pipes 1a, 20 with the first chamber. Springs 23, 24 tend to maintain the chamber 26 at a predetermined volume, and a throttle valve 21a in a pipe 21 connecting the reservoir with both the chambers determines the speed at which the bellows 16, 18 react to any pressure changes in the pipe 13. With the throttle 21a fully open and, e.g. an increase in pressure at the glands the volume of the chamber 17 is immediately reduced to adjust through the spring-loaded rod 4 a pilot valve 6 supplying hydraulic fluid to a servomotor 7 to open a valve 9 to admit steam from the boiler to a condenser 3b and so permit the partial closure of a valve 8 admitting steam from the boiler to the glands to reduce the pressure at the glands. In this case, the chambers 17, 26 have little effect on the movement of the rod 4, the liquid from the chamber 17 being quickly transferred to the reservoir 28. On partial closure of the throttle 21a, the rate of transfer of liquid from the chamber 17 to the reservoir 28 is reduced and transfer of liquid from the chamber 17 to the chamber 26 is resisted by the spring 23. Specification 498,351 is referred to.

As shown, for a variable-speed ratchet gear, the member 1 consists of spaced plates, 1, 1a and pivots about bearings 4, 4a. Oppositely revolving weights 11, 11a, and 12, 12a, are mounted on the beam the weights 11, 11a, being 180 degrees out of phase with the weights 12a, 12, respectively. The four weights are interconnected by bevel gearing as shown in Fig. 4, the weights 11, 11a being rotated from a motor 27a, and the weights 12, 12a from a motor 27. The motors are carried by the member 1 and oscillate therewith. The movement of the member 1 produces reciprocation of links 30, 30a, Fig. 5, which motion is transformed into unidirectional rotation of a shaft 39 through gears 32, 32a, 34, 34a, 36, 36a, and oppositely acting ratchet clutches 40, 40a. The shaft 39 may be the drive shaft of a vehicle.

Title: Improvements in or relating to quick-cooking cereal and method of making same
Inventor: ALLISON JIM E
IPC: A23L1/18
Filed: 1953-09-22
Abstract: In making a quick-cooking puffed cereal, e.g. rice, oats, wheat, farina (centres of hard wheat) and hominy, having for about 20 minutes after immersion in water at 200 DEG F. a rate of hydration at least one third higher than the original cereal, air is removed from the cereal, e.g. by moistening it and reducing the pressure, and replaced by steam under pressure, the cereal is cooked in steam at increased temperature and pressure, e.g. to effect substantially complete gelatinization of the starch content, the pressure is reduced explosively to puff the cereal and kept reduced until the cereal is set, i.e. does not collapse when it comes under atmospheric pressure.  The puffed cereal may be dried in air or in steam under reduced pressure.  Preferably, the moisture content of puffed wheat, farina and hominy is brought to a value between 10 and 15 per cent before reimposition of atmospheric pressure.  The cereal may be cooked at a pressure between 25 and 75 lb. per sq. inch which may be reduced to 2 inches of mercury absolute or less, e.g. to a value between 0,1 and 0,2 inch.  During the puffing and setting of rice, its temperature may be brought below 101 DEG F., preferably, below 40 DEG F. The puffed rice may contain small uniformly distributed cavities and after being immersed for 4 minutes in water at temperatures between 190 and 210 DEG F. it may absorb 20 to 28 per cent of its dry p  weight of water per minute for a period of 10 minutes.  The ratio of the puffed volume to the original volume may be between 1,66 and 3,50 for rice, oats and wheat, between 1,50 and 2,50 for farina and between 2,50 and 5,50 for hominy.  The ratio of the specific gravity of the puffed cereal to that of the original cereal may be between 0,285 and 0,600 for rice, oats and wheat, between 0,400 and 0,666 for farina and between 0,182 and 0,400 for hominy.  Specification 675,292 is referred to.  Reference has been directed by the Comptroller to Specification 759,478.

Title: Improvements in signal regenerators for telegraph and like systems
Inventor: DUUREN HENDRIK CORNELIS ANTONI
IPC: H04L1/00
Filed: 1948-10-06
Abstract: 683,607. Code telegraphy. HET STAATSBEDRIJF DER POSTERIJEN TELEGRAFIE EN TELEFONIE. March 15, 1949 [Oct. 6, 1948], No. 26099/48. Class 40 (iii). A signal reshaper for a system in which signals consist of mark and space elements received over a radio link and in which elements of one sort are distorted by elongation so that the elements of the other sort are too short to operate their associated receiving device comprises means for producing a predetermined adjustable delay between the time of application of both said elements to an input device and the response of an output device, the delays being different for marking and spacing elements respectively, or the delay being different at the beginnings of elements of one sort, e.g. marking elements, from that of the ends of said elements of said one sort. In the space condition of the circuit of Fig. 1, the valves B1, B5 are conducting and the valves B2, B6 non-conducting, the appropriate winding of the relay Re being energized to operate its armature to the spacing contact. Assuming the tap on the resistance R3 to be set at its mid-point and the values of the capacitances C1, C2 to be chosen to provide a charging period equal to half the length a, Fig. 2 (p), of a signal element period, on the reception of a marking element rendering the valve B1 non- conducting, the condenser C1 becomes charged after an interval of a/2, Fig. 2 (q), to a value which renders the valve B2 conducting. The valve B5 becomes non-conducting and B6 conducts so that the marking winding of the relay Re is energized and moves the armature to the mark position. At the termination of the mark signal B1 again conducts and the valve B2 is cut off. After a lapse of time a/2, the capacitor C2 is charged to a value such that the valve B5 conducts and the valve B6 is cut off, the operation of relay B5 moving the armature of relay Re to the spacing position. To allow for the elongation of, for example, marks relative to spaces, the tap on the resistance R3 is moved to a non-central position in which the time taken to charge the capacitor C1 is increased by a predetermined amount and the charging time of the capacitor C2 is reduced by the corresponding amount. The adjustment is for an increased time relative to a/2 by half the difference between the elongated marks and the normal time period a, Figs. 2 (r, s). A preferred or average adjustment is an increase of a/4 so that the beginning of the mark signals is retarded in the output device by 3a/4, but the marks are of the correct length a, the time of charging of the capacitor C2 being reduced to a/4, Figs. 2 (r<1>, s<1>). A modification, Fig. 3 (not shown), for response to frequency-shift signals generally duplicates the circuit of Fig. 1, but includes a flip-flop operation of the relay-control valves corresponding to the valves B5, B6 of Fig. 1.

Abstract: 966,175. Telegraphy. CREED & CO. Ltd. July 4, 1963, No. 26460/63. Heading H4P. In a telegraph transmitter, the transmission contacts are actuated by the arrangement shown. Code bars 1, operated by a keyboard, cause levers 6 to be selectively unlatched and to bear against cams 9. For an unlatched lever, as its cam 9 rotates lever 6 moves frame 16 anticlockwise and tongue 18 pulls slider 18 leftwards. The slot in which tongue 18 engages is wider than the tongue, so that, if frame 16 bounces, the bounce is not reproduced in movement of the slider. The angular position of striker 27 depends upon that of the slider, and at every bit interval cam 11 causes the striker to be moved substantially vertically so that one or other of its arms 35, 36 engages with rocker 39, moving it to left or right. The rocker opens one or other of leaf spring transmission contacts 43, 44. Although striker 27 is lowered during each bit, rocker 39 does not move because it is held frictionally in position by spring 41. Due to the large striking faces of the arms of striker 27 and of rocker 39, wear at these surfaces is reduced.
