Title: Improvements in and relating to mechanical and signal energy devices and apparatus
IPC: H03D7/00
Filed: 1963-07-10
Abstract: 1,045,495. Semi-conductor devices; piezoelectric elements. PHILCO CORPORATION. July 10, 1963 [July 10, 1962], No. 27303/63. Headings H1E and H1K. Also in Divisions H2 and H3] An electromechanical frequency - con - verter using the Doppler effect comprises a body 16 of semi-conductive material in which mechanical waves are transmitted and reflected from an electrically movable boundary 30. The body 16 may consist of a single hexagonal crystal of CdS or ZnO (both have piezo-electric and semi-conductor properties) which is provided at one end with a transducer formed by applying reverse bias between electrodes 18-24 to a depletion zone 25 at the end of the crystal. A signal at the frequency to be multiplied is applied through a band-pass filter 12 to the transducer 25 and propagated as a mechanical wave along the body 16 towards a second depletion layer 26 formed at the opposite end of the body. The boundary 30 of the depletion zone 26, which forms a wavereflecting discontinuity, may be axially moved by varying the potential applied to the electrode 18. Movement of the reflector causes modification of the frequency of the reflected wave by the Doppler effect. In order to achieve large increases in frequency, the boundary must move towards the incident wave at a constant velocity approaching that of the wave. Since the velocity of the excursion is proportional to the square root of the applied voltage, a sawtooth voltage with a parabolic ramp will produce the necessary effect. The fly-back period is practically instantaneous and produces no Doppler effect. The output wave is transformed into an electrical signal by the transducer 25 and fed to an output band-pass filter 14. In order to isolate the input from the output, the input filter has an output impedance which rises with frequencies above the pass band and the impedance of the output filter falls at frequencies below the pass band. Harmonics arising from parametric effects in the device may be eliminated by operating at frequencies which are not integrally related. In a modification (Fig. 2, not shown), the depletion-layer transducer 25 is replaced by a piezoelectric crystal of quartz or Rochelle salt.

Abstract: 897,336. Toys. MULLER, W. H., [trading as SCHREYER & CO.]. Aug. 8, 1960 [Aug. 7, 1959], No. 27420/60. Class 132(3) An automobile toy has mounted the effigy of a driver, the arms and head of which are movable, the hand of one arm being connected with the steering wheel, or the like, to partake in the movements thereof while the hand of the other arm is connected with a control element such as a gear change lever to partake in the movement of such element which derives its motion from the motor of the vehicle through a suitable transmission and the head is adapted to swivel and also derives its turning motion through the transmission. The movements of the arms 3, 4, head 1, steering shaft 19 and gear change lever 6 are controlled by a lever 15 pivoted at 16. A motor 17 drives a disc 9, having a pin engaging in a slot 14 in the lever 15, through a reduction gear train 8 a worm and wormwheel 10, 11 and a Maltese cross wheel 12 forming part of a Geneva stop mechanism. An arm 20 which engages the hub of the gear lever 6 extends through the lever 15. The lever 15 also pivotally engages a crank arm 21 secured to the head 1. The torso 2 has a drive member 22 engageable by the crank cam 21 after the head has swivelled a certain distance. One end of the lever pivotally engages with an arm 17 which extends from a disc mounted on the steering shaft 19 to move the wheels 18 and steering wheel 5. The direction of the motor may be reversed by axial movement of a spindle 26 by a control lever 23, pivoted at 25 to the body and contacting a cam 24 on the disc. The movement of the spindle 26 moves a reversing gear into the gear train. The spindle may be moved manually. An auxiliary lever 28 for moving the parts pivots on the lever 23. The lever 28 pivotally mounts a lever at one end, the lever having a toothed quadrant meshing with a gear on an extended hub of the gear lever 6. A toothed quadrant 30 along the length of the lever 28 meshes with a gear 31 at the end of the hollow shaft which mounts the torso 2, this movement being in addition to that produced by the crank arm 21. Raising the lever 28 disengages it. Reverse travel may be effected by a control lever contacting a cam on the disc and operating a switch which changes the poles of the motor. The vehicle may be remote controlled by operating a handle 41 disconnecting the automatic drive from the wheels 18 and steering shaft and connecting the remote control. A threeway switch may be used to switch on the motor for operation with automatic control and for forward and reverse travel with remote control. The reduction gearing may provide different speed ratios either by automatic control mechanism or manually.

Title: Improvements in meat packing
IPC: A23L13/00
Filed: 1930-09-15
Abstract: In packing poultry and other meat, the raw dressed meat is subjected to a treatment with common salt, e.g. by immersion in a strong brine, so that it takes up a proportion of salt in excess of that appropriate for seasoning, and is packed in a container together with a substantial amount e.g. 1/3 of the weight of the meat, of an edible gelatine or other jellifying solution.  Air is next exhausted from the container which is then sealed and heated to sterilize the contents and transfer salt from the meat to the jellifying solution to reduce the amount of salt in the meat to that appropriate for seasoning.  The heat treatment may be effected at about 240 DEG  F. for 30 minutes in a steam-heated retort, heated compressed air being introduced to maintain pressure on the container.  Cooling is then effected by spraying water on the container while still under pressure in the retort.  The jelly formed surrounding the meat acts as a preservative.
