Filed: 1964-01-01
Abstract: 1,006,984. Compressing gases. W. SOHGEN. Jan. 1, 1964, No. 68/64. Heading F1N. [Also in Divisions A5 and F2] A transfer valve for a breathing apparatus or pump comprises casing formed in two parts 1, 2 having an inlet 4, an outlet 8 and an exhaust 9. A valve body is fixed in the inlet and comprises a circular portion 11 which normally seats on seating 10 surrounding the exhaust and a peripheral lip portion 12 which normally closes the inlet 4. When the inlet pressure rises above the outlet pressure, the lip is flexed to allow flow from the inlet to the outlet. When the inlet pressure falls, the valve closes and the outlet pressure then acts on the circular portion 11 to allow flow from the outlet to exhaust. The lip portion may seat on a chamfered lip of the housing. The valve body may also have a bellows portion between the inner part of the portion 11 and the fixing stem 6. A similar shaped valve is used as a non-return valve for the inlet 25 of a pumping bellows 15. The bellows is provided with recesses 24a-24e for the fingers and thumb.

Filed: 1971-01-01
Abstract: 1332861 Semi-conductor devices WESTINGHOUSE ELECTRIC CORP 1 Jan 1971 [30 Jan 1970] 78/71 Heading H1K At one major surface of a thyristor one emitter region 26 is surrounded by the adjacent base region 22, both regions being contacted by an electrode 50 which shorts the PN junction 34 between the regions 22 and 26. At the other major surface 14 a central surface portion of base region 24 carrying an electrode 40 is surrounded by a zone 20 of the opposite conductivity type carrying an electrode 38. The zone 20 is itself surrounded by a further surface portion of the base region 24 carrying an electrode 42 connected to the electrode 38, and finally another zone 18 of opposite conductivity type to the base region 24 and carrying a further electrode surrounds the last-mentioned surface portion of the region 24. The zone 18 overlies, at least in part, a portion of the lower base region 22 which does not itself overlie the lower emitter region 26. The electrode 42 may, as shown, cross the PN junction 30 between the region 24 and zone 20, and the interconnection of the electrode 42 to the electrode 38 may be by a wire or, as shown, by a body 112 of metal, e.g. Ni-Cr; or conductive ceramic, e.g. a spinal, titanate or niobate, molybdenum disilicide or NiAl. The body 112 may be pressed into contact with the electrodes 38, 4z or may be integral therewith. In the former case the body 112 is pressed upon by a Cu terminal member (120), Fig. 6 (not shown), contacting the outer electrode (36) on the zone (18), an insulating body (132) being provided between the terminal member and the body (112). A central pressurized contact (122) to the electrode (40) passes down through an aperture (124) in the terminal member (120). Suitable semi-conductor materials are Si, Ge, SiC, GaAs, A1P or II-VI compounds. The electrodes 36-42 may comprise Al or Sb in Ag and the lower electrode 50 may be of Mo, W, Ta or alloys thereof soldered to the lower surface of the device.

Title: Improvements in or relating to x-ray diagnosing apparatus
IPC: H05G1/38
Filed: 1959-01-01
Abstract: 906,564. Protective arrangements. SIEMENS-REINIGER-WERKE A.G. Jan. 1, 1959 [Jan. 2, 1958], No. 94/59. Class 38 (5). [Also in Group XXXV] In X-ray apparatus in which the duration of exposure time can either be pre-set by means of a time switch or determined by an automatic exposure device, the time switch is operative when the automatic exposure device is in use to prevent the maximum safe period being exceeded. When the exposure time is to be pre-set by the time switch, the voltage to be applied to the X-ray tube, the current to be taken by the tube and the time of exposure are set by knobs 1, 6 and 9 respectively. These knobs adjust an autotransformer 3, variable resistor 7 and time switch 10 and in addition move taps 11, 14 and 16 on potentiometers 12, 13 and 15. If the setting of the knobs is such that the X-tube would be overloaded, the voltage at tapping 16 biases a triode 18 so that it does not conduct and a relay 19 having contacts 20 is not energized. If the setting is permissible, then the triode 18 conducts, contacts 20 are closed and the exposure is initiated by closing a switch 37 to energize the coil 21 of a contactor 22 and is terminated by the time switch 10. When the automatic exposure device is to be used, a switch 24 is closed. This causes a reversible motor M to adjust the time switch 10 and tapping 16 to their maximum settings as determined by the settings of knobs 1 and 6. When these maximum settings are reached, the voltage at tapping 16 is such that triode 18 is conducting, relay 19 is energized and contacts 20 are closed, and a further triode 31 is non conducting, a relay 30 is not energized and its contacts 42 are closed. Auxiliary contacts 19a, 30a of the relays 19, 30 are now in such positions that the motor field winding 29 is de-energized and the motor stops. The exposure is now initiated by closing contacts 36 to cause the contactor 22 to close. The emission of the X-ray tube is measured by an ionization chamber 41 of the automatic exposure device 38 which, when the required exposure has been made, opens the contacts 36 to terminate the exposure. If, however, the tube 2 has been in operation for the maximum period permitted for the preset load before the automatic exposure device 38 functions, then the exposure is terminated by the time switch 10.

Title: Manufacture of lens, optical system and focusing mirror by minute machining
Inventor: IGOORU AI BORU
IPC: G02B1/02
Filed: 1993-01-04
Abstract: PURPOSE: To form a lens, optical system and focusing mirror by utilizing a highly developed fine machining technique for Si. CONSTITUTION: Smooth three-dimensional curves are manufactured by using two steps of pattern forming stages. In the first step, the edges, i.e., wall parts of an Si block to be curved are delineated on the surface of a substrate 10 by the conventional photoresist and etching technique. In the second step, buffer materials are grown at the edges, i.e., wall parts to be curved. The edges, i.e., wall parts are projected toward the outer side and the inner side by housing the buffer materials, by which a threedimensional bowl shape is formed together with the buffer materials. A mirror finished surface is formed when the buffer materials are removed while the edges, i.e., wall parts retain the bow shape at the end of this step. A lens 20 is formed when the block in which the curved buffer materials are made to remain is removed.

IPC: G06F15/16
Filed: 1990-01-17
Abstract: A method of communication in a computer system is provided for transferring information between multiple, concurrently operating programs, each of which may have a respective window display. The user communicates with each of the application programs through the window display as well as through an input device, such as a mouse or keyboard. A list of information codes is registered with a dispatcher program for each of the application programs which requires data. One or more of the application programs generate templates which include data and a corresponding information code. The generated templates are transmitted to the dispatcher program. The dispatcher program then compares the information code in the received template to the registered list of information codes to find any matches and thereby identify the one or more application programs which have registered to receive the information in the received template. The dispatcher program then transmits the received template to each of the identified application programs. Information communication is therefore carried out between multiple operating programs without user direction for the steps of the communication process.

Abstract: 543,694. Reproducing music &c. ELECTRICAL RESEARCH PRODUCTS, Inc. Jan. 8, 1941, No. 277. Convention date, Jan. 27, 1940. [Class 40 (iv)] A circuit for combining the outputs of two sound-reproducing or other channels in which the currents may be either in phase conjunction or phase opposition includes a switching relay or relays which are dependent on the relative phase condition. In Fig. 1, the two pick-ups associated with a sound record are connected by way of transformers 2, 3 and amplifiers 4, 5 if desired to a pair of transformers 6, 7 each having two secondary windings 8, 10 ; 9, 11. The two windings 8, 9 are connected in aiding relationship and their combined output is applied through a detector 16 to a relay 20, while the two windings 10, 11 are connected in opposition and their combined output is applied through a detector 17 to a relay 21. Thus, according to the type of record being played one or other of the relays 20, 21 is operative to connect the appropriate pairs of windings 8, 9 or 10, 11 to the output circuit 26, 27. A reversing key 100 enables the operation of the circuit to be tested by connecting the same source to both transformers 2, 3. In one modification of this arrangement, the two 'secondary circuits of the transformers 6, 7 are connected through rectifiers to the windings of a differential relay, while in another modification, a single relay is controlled by one secondary circuit only. In Fig. 3, the input transformers 52, 53 feed through amplifiers 54, 55 the two primary windings 56, 57 of the output transformer which have their common point connected through a resistance 58 to the anode battery 59. With the relay 63 normal, the windings 56, 57 are connected for dealing with input currents in phase opposition. If currents in phase conjunction are received, however, current flows in the resistance 58 and through a detector 62 causes the operation of the relay 63, which reverses the connections of the winding 57. In Fig. 5, the input currents are fed through transformers 88, 89 to adjacent arms AC, CB of a resistance bridge, the diagonal CD of which is connected through a detector 95 to a relay 96 arranged to connect either diagonal of the bridge to the output circuit. The various types of push-pull records are explained.
