Abstract: 969,473. Clocks and watches. S. DAVALL & SONS Ltd., and R. W. G. SOMERVELL. Oct. 6, 1960 [Nov. 27, 1959],No. 40357/59. Heading G3T. An escapement comprises two coaxial escape wheels 13, 16, Figs. 1 and 2, interconnected by a spring 26 for relative movement limited by stops 28, 31 extending from the wheel 13. The teeth 17 of the wheel 16 have locking and impulse faces 18, 19, and the teeth 14 of the wheel 13 has locking faces 15 engageable by pallets 21 (not shown) on an escape lever when the two escape wheels are moved relatively against the bias of the spring 26, the arrangement being such that when the wheel 13 is driven to cause successive pallet engagement of the locking and impulse faces 18, 19, the impulse is limited by pallet engagement of a locking face 15 when excessive driving force causes relative movement of the two escape wheels against the bias.

A direct-contact condenser, suitable for use as a feedwater heater for turbine plant, comprises a vessel 30 having an inlet 37 for steam, nozzles 31 for spraying-in the feedwater, and a downwardly-inclined duct 38 into the mouth of which feedwater is sprayed from screen 43 The spray water from nozzles 31 is caught on perforated tray 35, and then descends as droplets 40 into the lower part of the vessel. Steam entering inlet 37 is deflected downwards and passes below tray 35, where some of the steam is condensed by water-droplets 40. Remaining steam flows up around tray 35 into the upper part of the vessel where further steam is condensed by the water-sprays from nozzles 31. The remaining steam, together with non-condensable gases, enters duct 38 through apertures 41, and the remaining steam is condensed. Warm water flows out of the lower end of duct 38 through screens 47. Non-condensable gases are vented from the upper end of duct 38 through outlet 48. The required hot feedwater flows out of the vessel through outlet 49.

Title: Method and apparatus for evaluating echo signals to identify  useful echo signals
IPC: G01S15/18
Filed: 1972-09-01
Abstract: 1358812 Echo-sounding FRIED KRUPP GmbH 1 Sept 1972 40722/72 Heading H4D In an echo-sounding system the reception times of the first two echoes arriving after the transmission reverberation has decayed are compared with one another and with the reverberation duration to determine whether the echoes are valid, possibly valid, or spurious. The invention is applicable to marine sounding in shallow water, where multiple reflection of a transmission pulse occurs between the water bottom and a ship and it is important to know when a multiple echo has given rise to a false distance reading on a digital or pointer instrument. In the embodiment of Figs. 1 and 2 a pulse I from generator 3 triggers the transmitter 4 and starts a timer 8À1. A detector 6 detects the reverberation in the output signal S2 of receiver 5 and the detector output waveform Sn opens a gate 7 at the end of the reverberation. Echo signals E passing through the gate are shaped at 7a to give pulses S3, the first of which stops a timer 8À3 started by pulse I, and the second of which stops a timer 8À3 started by the stopping of timer 8À2. The durations t 2  and t 3  of the output signals S5, S6 of timers 8À2 and 8À3 respectively are tested for equality at 9 and 9À1 to identify multiply-reflected echoes. If t 2 >t 3  or <t 3  by a pre-set margin, an output signal appears at 9À1a or 9À1b respectively. A signal S8 of twice the reverberation duration t 1  is generated at 10 and a coincidence circuit 11 gives an output S9 if the first echo is received within time 2t 1 . The output S9 actuates an indicator 18, to show that shallow-water echoes are being received, and is lengthened by a store 12 to give a signal S10. At a time determined by range selector 2, and shortly before a further transmission pulse, timer 8À1 is stopped and the trailing edge of its output S4 provides an interrogation pulse for logic network 13 (and a stop pulse for timers 8À2 and 8À3 if no echoes have been received). The network gives a first output signal, indicating a valid first echo, if either (a) t2>2t1 or (b) t1<t2<2t1 and t3 = t2. The network gives a second output signal, indicating a possibly valid first echo, if t1<t2<2t1 and either t3> t2 or no second echo was received after 2t1. The network gives a third output signal, indicating a spurious first echo, if t2> t3. Stores 16À1, 16À2, 16À3 are each arranged to deliver a signal after receipt of a predetermined number of logic network output signals.

IPC: A23L23/10
Filed: 1960-11-30
Abstract: A storable food is made by forming a pulp by adding an edible liquid to an edible substance which acquires bonding properties on being mixed with liquids, then adding to the pulp a comminuted, edible, absorbent substance in such a quantity that the liquid of the pulp is absorbed by the absorbent substance, the particles of which remain bound together by the residue of the pulp to form a mass of mouldable consistency, whereupon the mass is formed into shapes and the shapes are dried.  The pulp may contain proteins such as gluten, casein and gelatine, potato, flour, fruit, vegetables, ground cereal products, carbohydrates; the absorbent and flavouring substances may be cheese, mushrooms, spices, sweetening agents, honey, cocoa, dried mean, dried, e.g. spray dried, foods, ground dried fruit, candied peel, "seed grains", skinned milk powder, dried yeast, marzipan, nougat. Examples are concerned with the preparation of pasta-type products, for adding to soup, from strained, cooked vegetable such as asparagus, cooked wheat flour paste, spray-dried mushroom flovouring or powdered dried mushrooms, flour and yeast, the preparation of dry "bread dumplings", for reconstitution in a hot liquid, from a paste of cooked wheat flour, with, if desired, gelatine or gluten and lactic acid solution, bread crumbs or cubes, dried vegetable, dried whole egg and cream of tartar, and the preparation of pasta-like products for sweet dishes, of ingredients for cake or fruit bread, and of cake decorations from casein, boiled comminuted cereal grains, e.g. rice flour, chopped dried fruit, e.g. grapes, dates, almonds, a vitamin preparation, sugar or sugar syrup, crumbed ginger-bread, poppyseed, ground, dried pears.

Abstract: 1504351 Power-assisted steering systems ZAHNRADFABRIK FRIEDRICHSHAFEN AG 8 Oct 1975 [12 Oct 1974] 41225/75 Heading B7H A power-assisted steering system for a vehicle comprises a steering shaft 7, Fig. 1, carrying pins 12, 13 respectively coupled to a reaction piston 10 providing reactive feel and to a control piston 11 controlling fluid flow to servo-chambers 16, 17, the reaction piston 10 being provided with further pistons 62, 62A, Fig. 2, urged apart by a spring 63 and operative to limit reactive feel forces. Reaction chambers 80, 80A associated with the reaction piston 10 are normally communicated with servo-chambers 17, 16 through bores 67, 67A. Excessive pressure in either of reaction chambers 80, 80A causes the adjacent piston 62 or 62A to move against the action of spring 63 so as to interrupt communication with the associated bore 67 or 67A. The steering shaft 7 is connected by a torsion bar 6 to a spindle 5. The spindle 5 is coupled by recirculating balls 4 to a servopiston 2 meshing with a sector shaft 3. The neutral position of the control piston 11 may be adjusted by means of adjustable screws 51, 51A.
