Title: Improvements in acoustic radiators
IPC: G10K13/00
Filed: 1962-12-11
Abstract: 1,030,119. Acoustic radiators. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Dec. 11, 1962 [Dec. 11, 1961], No. 46832/62. Heading G5J. An acoustic radiator comprises a rectangular vibrating strip 1 driven by two transducers 21, 22 connected to the same face of the strip at opposite ends thereof. The transducer 21 transmits a wave along the strip to provide, in the surrounding medium, a directional wave indicated by the lobe 211, Fig. 4. By varying the frequency of the transducer, the whole of the right-hand quadrant can be scanned. Similarly, the left-hand quadrant can be scanned by the lobe 221 provided by the transducer 22. With equidistant parallel reflecting elements 3 on the strip 1 to break up the radiating surface, the lobes may be made to scan the backward quadrants as shown in Fig. 3. The Specification acknowledges prior devices in which a strip is driven by a single transducer at one end and is supported at the other end by acoustic cement or putty.

Title: Control systems for sterilizers
IPC: G05B19/07
Filed: 1974-10-31
Abstract: 1458718 Automatic control of sterilizers SYBRON CORP 31 Oct 1974 [28 Nov 1973] 47187/74 Headings G3N and G3R A gas-humidity type sterilizer includes a chamber which is pre-heated, and a plurality of fluids which are also pre-heated. Following the pre-heating stage, the fluids are fed into the chamber sequentially for timed periods. The process is shut down if the chamber temperature exceeds upper and lower limits, and a process termination signal is produced at a predetermined time after the end of the pre-heating stage. In the system shown, a sterilizing gas, water and steam, and a sterilizing chamber are heated by respective circuits 10, 12, 14. Temperature sensors 32, 34, 36 energize an AND gate circuit 34', detailed in Fig. 5 (not shown), which produces an enabling signal when all the desired temperatures have been reached. This signal starts a cycle timer circuit 44, using a PUT pulse generator and flipflop counter arrangement, Fig. 6 (not shown), a circuit 26 which admits steam to the chamber for a time determined by a delay circuit 40, and timing circuits 36', 38 which include PUT's and control the admission of gas to the chamber for a pre-set time following an initial delay. A circuit breaker release circuit 58, including a silicon unilateral switch and controlled rectifier, Fig. 4 (not shown), removes power from the whole system in response to signals from under and over temperature detecting circuits, 54, 52, the under temperature circuit 54 becoming operative only after the circuit 34' produces an enabling signal. A chamber door interlock switch 33 also removes the power supply. Temperature regulation of the steam and water supplies and the sterilization chamber is controlled by individual circuits, as shown in Fig. 2, each including a thermistor sensor 86 connected to a Schmitt trigger circuit 84 which changes state when a desired temperature is reached, thereby supplying a signal on line 90 to the enabling circuit 34' and simultaneously turning off a uni-junction transistor oscillator 70 which controls a triac 62 connected in series with a heater 64. If the temperature subsequently falls, the trigger circuit again changes state to energize the heater and restore the desired temperature.

Abstract: 998,791. Double-twist spindles. BARMER MASCHINENFABRIK A.G. Dec. 17, 1962 [Dec. 16, 1961], No. 47566/62. Heading D1D. In a double-twist spindle comprising a stationary carrier for two or more rotatable packages arranged side-by-side from which the threads are drawn off tangentially to be ballooned around the package, the spindle proper stops short of the adjacent package, the packages are supported for movement transversely of their axes on elements arranged on a fixer part, and a freely rotatable cylindrical support is provided against which the packages can bear with pressure. In the inclined two-package arrangement shown, the packages are mounted on discs 3, 4 carried by a fixed part 1 to slide, under the pressure of spring- hinged rollers 15, 16, towards a two rotatable cylindrical supports 10,11. These are mounted on pivots 6, 7, 8, 9 in the member 1 and an endplate 5 of a member 2 also carried by the part 1. Fixed or rotatable thread guide rods 19, 20 or eyelets are arranged between the parts 1 and 5 and balloon-restricting rings may be carried by the members 3, 4, 5. The supports 10,11 may be arranged to move inwardly as the packages are unwound as also may be a member simular to the supports which may replace the spring- pressed rollers 15, 16. The members 10,11,15,16 being rotatable equalize the rates at which the yarns are withdrawn. A horizontal arrangement is described, Fig. 7 not shown, in which the discs are replaced by plates with U-guides for the sleeves of the packages, while the rollers 15, 16 are dispensed with, the packages moving by gravity.
