Filed: 1940-01-13
Abstract: 538,092. Blowpipe burners. LINDE AIR PRODUCTS CO. Jan. 13, 1940, No. 781. Convention date, Jan. 14, 1939. [Class 75 (i)] [Also in Group XXII] In de-seaming or de-surfacing ferrous metal bodies such as billets, ingots, blooms &c. particularly prior to rolling operations, a large jet of oxidizing gas is impinged along and obliquely against the heated surface to form a groove and at the same time a small jet of oxidizing gas is impinged at one or both sides of the large jet sufficient to react with the fin-forming material ejected from the groove but insufficient to react with the surface of the body. The blowpipe which is arranged obliquely to the surface T may be provided with a nozzle having a central oxygen passage O1 surrounded by heating gas passages H, the wall of the passage O1 being provided with slots S forming wedge-shaped passages through which auxiliary streams of oxygen pass to impinge against the edges of the groove G formed by the jet O1 in order to exhibit the formation of ridges or fins. A series of blowpipes may be arranged in a row in a head the auxiliary jets being arranged to be overlapping in the areas of ridge formation between the grooves and the outer auxiliary streams exhibiting fin formation along the borders of the de-surfaced area. The slots may be arranged at 90 degrees apart as shown or at 180 degrees apart. The blowpipe may first be held upright to direct the heating jets issuing from passages H around the surface and when the work becomes red hot the blowpipe is tilted so as to effect the de-surfacing operation. Another form of blowpipe consists of a nozzle with a main oxygen passage 03, Fig. 7, and a fan of auxiliary oxygen passages S3 which lead from the passage 03 at 15, Fig. 9, and are inwardly directed over the edges of the groove or alternatively arranged parallel with the main passage.

Title: Improvements in or relating to apparatus for holding animals in position whilst being slaughtered
IPC: A22B5/02
Filed: 1931-01-09
Abstract: 361,180. Holding animals during slaughter. MOIR, J. R., One House, Henley Road, and SANDERS, C. E., 96, Bramford Road, both in Ipswich. Jan. 9, 1931, No. 848. [Class 81 (ii).] Apparatus for holding an animal during slaugliter of the type comprising a rotatable cradle, is provided with automatically operated means for holding the animal therein during part of the rotation and for releasing said holding means for ejection of the carcass. The cradle 6, comprising two endplates 6a, 6b, side walls 6c, 6d, which may be hollowed to conform to the shape of the animal, and platform 6e, is rotatable on rollers 7 about a tie-bar 5 passing through arcuate slots 6h in the endplates. A lever 8, actuated by a pedal 9, engages slots 10, 11 and locks the cradle in a vertical or horizontal position respectively. The platform 6e is hinged at 12 to a tie-rod 6i and comprises a main portion 13, and a trap 14 at the end of the apparatus. The weight of the animal on the trap moves the trip lever 18 and, through a rod 17, releases the catches 15 allowing the platform to drop. A pedal for operating the trip mechanism is also provided. The animal is wedged between the outwardly inclined walls 6c, 6d and is then stunned. On depressing the pedal 9, the animal's weight rotates the cradle to a horizontal position, where it is locked by the lever 8 engaging the slot 11. The animal is stuck and the pedal again depressed to allow the cradle to rotate and eject the carcass, when the cradle returns by gravity to its normal position. The platform 6e is so weighted as to swing at the same time into its normal or closed position. The means for securety holding the animal during the rotation may comprise an inclined portion 6g of the wall 6c hinged at 22 to the vertical portion 6f and normally locked in the inclined. position by a bolt 23 engaging a socket 24 and, at its lower end, the edge of the platform 6e. The platform as it drops pulls down the bolt 23, and the hinged portion 6g springs to the vertical position. Upon rotation to the ejection position, the weight of the body depresses the hinged portion which engages the bolt 23, the body slides out and the platform 6e swings into the closed position under the catch 25 of the bolt 23. A modified securing means, Figs. 3 and 4, comprises a frame 30, 31 having a screen 33, suitably of sheet metal, hinged thereto at 32. Catch members 34, 35 on the cradle and screen respectively lock the screen during part of the rotation, and become disengaged during the rotation into the ejection position, allowing the screen to be pushed aside bv the carcass. The end of one of the walls is cut away at 36 to give access to the throat, and a water supply pipe 37 is provided.

Patent GB-1334953-A (GB)
Title: Echo-sounding
IPC: G01S7/60
Filed: 1971-01-07
Abstract: 1334953 Echo sounding ELECTROAOUSTIC GmbH 7 Jan 1971 [7 Jan 1970 (2)] 901/71 Heading H4D [Also in Division G4] A method of recording echo signals from two soundings made in opposite directions using a recording member moving in only one direction includes storing echoes received from one direction in their order of occurrence and reading them out of the store in the reverse order, whilst recording. Cam N, Fig. 1, closes contact NK1 as stylus SN reaches the bottom of record sheet RP. This causes a pulse to be transmitted towards the surface from transmitter SW1 mounted on a fishing net. Also gate G7 is opened allowing clock pulses to shift register SR. Echoes are received and fed to the register input through gate G9. Generator CG also drives a ring counter RZ having the same number of stages as the register. When the counter RZ reaches its zero position bi-stable M6 is triggered through gate G6 stopping the shifting of the register RS and counter RZ. Bi-stable M7 is also triggered, blocking the echo and trigger inputs to the register and opening gate G10. When the pen SN reaches the top of the sheet RP contact NK2 is closed and the clock pulses are once again fed to the ring counter R7 which opens the gates G1 ... G5 in succession, thereby reading the store contents out in the reverse order on to the writing conductor KS through gate G10. When the counter reaches its zero position, bistables M6, M7, M8 are all triggered and the transmitter SW2 transmits a pulse towards the sea-bed, the echoes therefrom being recorded directly via receiver EW2 and amplifier E2. In a second embodiment, Fig. 2, the record pen cam N produces a single timing pulse which is delayed in units V1, V2, V3 to provide all the triggering pulses. When a pulse appears at the output of V2 a signal is transmitted from SW1 and bi-stable M1 opens gates T2 and T3 such that echoes from receiver EW1 and clock pulses from generator CG 1 are fed to register SR which has n stages. After a delay V3 bi-stable M1 is triggered back and the storage cycle stops. When the pen SN reaches the top of sheet RP contact NK is closed which triggers bi-stable M2 through gate T5, thus opening gate T6, allowing the register SR to be clocked by pulses from generator CG2 operating at (n-1) times the frequency of CG1. CG2 also drives a ring counter RZ having (n-1) stages and the output of one stage is fed to gate T8 which also receives the output of register SR. The register SR is now connected in a ring through gate T7 and so every (n - 1 ) clock pulses the register output is fed via monostable M3 to the record pen SN. Since the register has n stages, the information is thus read out in the reverse order. After a delay V1 each element of the store has been read out and bi-stable M2 is re-triggered and the downwardly directed pulse is transmitted from SW2. The delay V3 may be replaced by a threshold circuit SS which detects the strong surface echo, to terminate the storage cycle.

Title: Method of evaluating and apparatus for analyzing recording characteristics of a recording medium with a prescribed analog electrical signal
Inventor: EFRON EDWARD
IPC: G11B27/36
Filed: 1991-03-21
Abstract: Method and means for evaluating the quality of audio and/or video transfer characteristics of a device upon which, or through which, audio and/or video information is contained, or passes, respectively. Both method and apparatus concern the evaluation of the quality of information transfer in the recording and playing back of a recording medium or in the transferring of audio and/or video information through an information handling device referred to as a throughput device. Unit evaluation is accomplished by establishing an input signal of known content, measuring selected parameters of selected parts of the input signal, feeding the input signal to the unit under test, measuring the parameters of parts of the output signal from the unit under test corresponding to the same selected parts of the input signal, and comparing the selected parameters of the input signal with the corresponding parameters of the output signal. Whether monitoring the quality of the signal transfer characteristics of a throughput device, a magnetic tape containing program material, or a video disc, master disc or replica, a "siganture" is created for the unit under test, and subsequent analysis of the unit as it progresses along a production line or of a copy made on the same or alternate recording medium results in a second "signature" which is compared against the first signature to make a determination as to the quality of the signal handling or transfer characteristics of the unit. In this manner, out-of-tolerance conditions can be automatically detected, thereby eliminating subjectivity and providing consistency in the quality level of device testing.
