Abstract: 644,965. Toys. CASCELLOID, Ltd., SENIOR, H., HENSMAN, J., and WARD, W. T. Sept. 1, 1948, No. 23061. [Class 132 (iii)] A doll having a head 11 and a hollow resilient body 10 forming an air chamber, has in the chamber a liquid container 18 connected by a tube 15 with the mouth, and by tubes 25 with tear openings in the doll's head. The container 18 is tubular, and is connected to internal eye protrusions 22 by the pipes 25 and channels 24, and to the interior of the air chamber by an auxiliary tube 21. If the container 18 is empty, squeezing of the doll forces air out of the mouth to simulate breathing, or if it contains liquid, this may be forced out of the mouth by previously tilting the doll to introduce liquid into the pipe 15, or by closing the mouth, out of the eyes. Tilting the doll puts liquid into the base of the doll, from which it can seep through a passage 26. Reeds may be fitted-in the limbs to make a noise upon the doll being squeezed. Specifications 534,706 and 600,702, [Group V], are referred to.

Abstract: 1486149 Change-speed control BORG WARNER CORP 28 May 1975 [21 June 1974] 23249/75 Heading F2D Actuation of a valve controlling pressurization of a hydraulic motor of a fraction device, e.g. a brake in an automatic transmission of a vehicle, is dependent on the direction of relative rotation of parts of the device so that a smooth ratio shift is obtained in conditions involving a reversal of torque in the device. In a transmission in which a multiple disc brake, corresponding e.g. to the brake 24 in the transmission disclosed in Specification 1,362,424, is applied by a piston 20 in the 3-2 downshift the direction of rotation of driven plates 26 relatively to the fixed piston and cylinder and plates 28 is initially in the direction F so that pressure applied in an actuating chamber 22 causes only partial brake application because a ball 62 in contact with one of the driven plates 26 is rolled in an aperture 64 in the end plate 28 to cause a lever 60 to hold a ball valve 48 off a seat 46 to prevent pressure build up in the chamber 22. When, during the shift which also involves release of a clutch (not shown), the friction plates 26 begin to rotate in the reverse direction R the ball is rolled to the position shown to allow closure of the valve and full application of the brake. Should the shift be made under closed throttle when no reversal takes place the brake will remain only partially engaged until torque is again transmitted. The brake is also applied to effect the 1-2 upshift but in this case the valve is ineffective to delay the application because the plates 26 are initially rotating in the direction R.

Filed: 1966-05-26
Abstract: 1,139,702. Glass melting. LIBBEY-OWENS-FORD GLASS CO. 26 May, 1966, No. 23610/66. Heading C1M. [Also in Division F4] In a method of producing glass wherein a glass batch is heated and melted in a continuous tank furnace 10 having a "hot spot" A intermediate the ends of the tank, heat is absorbed from preselected areas of the bath 12 located adjacent the "hot spot" to modify the thermal gradients and accelerate and control the thermal currents. Batch materials are introduced into the charging end of the furnace and float on the bath 12 and are carried through melting and refining chambers to a discharge end. The absorption of heat controls the thermal currents adjacent the "hot spot" A to sweep unmelted particles of batch material toward said charging end of the furnace and prevent their being carried by the natural flow of the bath into the refining chamber. The heat is absorbed by placing a plurality of cooling elements 28 transversely of the bath closely adjacent the "hotspot" A. These cooling elements 28 project upwardly into the bath 12 through the tank floor, the upper ends terminating just below the surface of the molten glass, and they are spaced sixteen inches apart. The elements comprise a pair of concentric tubes 30, 31 the upper end of the outer one being closed and a cooling medium, e.g. water, being passed up through the inner tube and down and out through the space between the two tubes. The elements 28 also act as a physical barrier to prevent large unmelted batch lumps flowing into the refining area. By this selective absorption better stirring and homogenization of the glass is achieved.

Filed: 1927-09-08
Abstract: 277,954. Siemens - Schuckertwerhe Akt.-Ges., (Assignees of Siemens-Schuckertwerke Ges.). Sept. 22, 1926, [Convention date]. Protective or safety devices, auxiliary; regulation of exciting machines; alternating-current induction machines.-In order to effect rapid demagnetization of an alternating - current machine, the excitation is supplied by the difference of two opposing fields, the greater of which can be caused to disappear automatically in dependence upon change of state in the mains or in the machine. Fig. 1 shows the invention applied to an asynchronous generator 1 feeding mains 2. The excitation for the generator is derived from a compensated commutator exciter 4, the rotor of which is fed from the opposing secondary windings of two transformers 6, 7 the primaries of which are connected to the mains 2. The effect of the transformer 7 preponderates throughout the range of regulation of the transformer 6, but if the mains voltage rises above a predetermined value, a switch 8 opens the primary circuit of the transformer 7 and the excitation of the machine 4 is derived wholly from the transformer 6 and consequently is reversed. In the case of a synchronous machine, the continuous-current exciter has a regulatable shunt field winding and an opposing and preponderating winding fed at constant voltage, the circuit of which can be opened automaticaly as in the first described example.
