Abstract: 402,372. Opening and emptying hollow organs of the body. VOGEL, R., 11, Rothenbaumehaussee, and LIND, J. H., 5, Adolf-Hitler Platz, both in Hamburg, Germany. Aug. 1, 1933, Nos. 21568 and 21569. Convention dates, Aug. 1, 1932 and July 19, 1933. [Class 81 (ii).] A device for opening hollow organs of the body having infectious contents, such as intestines and gall cysts, comprises a hollow tubular element connected to suction and so formed at one end that it forms an air-tight seal with the wall of the organ to be treated, which wall is then opened by an instrument guided within said hollow element through which element the contents of the organ are led away. A stiff rubber tube 4, which may be funnelshaped at its lower end, in fitted to a tube 6 closed by a stopper 7 through which passes a wire 2 connected to a diathermy apparatus. A branch 5 leads to a collecting vessel connected with a suction pump by a tube carrying a manometer. The wire 2 is connected to a holder 16 for two crossing sheet metal electrodes 13, 14 formed with projections 15 which contact with the wall of the intestine 1 and cut by diathermic action. Four metal strips 17 hold the electrode in position. When the intestine has been opened and discharged, the hose 4 can be sewn to the wall, the stopper 7 with the electrode removed, and another closure member fitted. Several instruments may be used simultaneously connected to a common suction vessel, In a modification, Figs. 4 and 5, a tube 21 with a cutting blade 22 slides in a tube 20, being guided by a pin 25, engaging a helical slot 24 and capable of being held in retracted position by the aid of a knob 27 mounted in a casing 28 which is carried by a sleeve 29, screwed on the tube 20 and held by a bolt 30. A rod 31, hollow at least at its lower end and carrying a wire guard 35, slides in the tube 21, a slot 33 engaging the pin 25. The tube 20 has a branch 36, and a mouthpiece 37 enclosing an annular space 38 communicating with a tube 39. The edge 41 projects beyond a ring of openings 40.

Title: Improvements in or relating to electric circuits employing transistors
Inventor: GARLAND BERNARD
IPC: H03B5/36
Filed: 1961-06-16
Abstract: 982,568. Transistor amplifiers, oscillators and limiters. GENERAL ELECTRIC CO. Ltd. June 13, 1962 [June 16, 1961], No. 21882/6#. Heading H3T. A circuit comprises first and second transistors 48, 51 of opposite conductivity having first electrodes connected together the arrangement being such that when no input is supplied to the first transistor 48 the second conducts to clamp the first electrode of the first transistor, and when an input is applied to the first, the second transistor 51 is cut off, and the first functions as an amplifier. As described, the circuit forms a limiting amplifier 48, 51 in the control circuit of a constant amplitude oscillator. The D.C. control signal is fed to the base of transistor 8 in the oscillator 8, 9, Fig. 2, via the common emitter amplifier stage 48, and in order to prevent the transistor 8 from saturating on switching on, the output from PNP transistor 48 is shunted by the collector-emitter path of NPN transistor 51 which is biased to conduct when no input is applied to transistor 48, and so limit the collector potential of transistor 48 to a value insufficient to cause transistor 8 to saturate. The oscillator comprises two reciprocally coupled transistors 8, 9, with a crystal 18 in one of the coupling circuits. The output is taken from a tuned circuit in the collector of transistor 8 and fed via a tuned negative feedback amplifier 23, 24 to the output circuit 3, 4. A portion of the output is also taken from a tuned circuit 33, 34 and is fed back to provide the control signal. Specification 982,569 is referred to.

Title: Improvements in thermionic valves
IPC: H01J19/02
Filed: 1933-08-04
Abstract: 420,546. Thermionic valves; valve modulating and generating circuits. SCHUETZ, F., 11, Reichsratstrasse, and TOMBERG, V., 2, D÷blergasse, both in Vienna. Aug. 4, 1933, No. 21981. [Classes 39 (i) and 40 (v)] The plate of a thermionic valve is replaced by a piezo-electric plate 3 excited to resonance and oscillating at least partly in the direction of impact of electrons from the cathode 1, the plate 3 being rendered conductive on its side 4 facing the electrons. A tuned circuit 8, 9 connected to metal coatings 4, 5 on the plate 3 may be excited from a generator of the frequency of the plate 3, the coating 4 being maintained at a constant or alternating potential. As shown, a reaction coupling between an anode coil 7 and a grid coil 6 causes the valve to oscillate. One frequency may thus be modulated by another frequency or the plate 3 may be excited by electron impact. In a Barkhausen-Kurz oscillator, the plate 3 may be used for modulation of the ultra-short waves.
