Title: Improvements relating to ventilation panels or windows
IPC: B60H1/26
Filed: 1944-11-24
Abstract: 583,735. Windows; ventilators. AUSTER, Ltd., and SMALL, W. W. Nov. 24, 1944, No. 23428. [Classes 20 (iii)] and 137] A window or panel assembly comprises a non-slidable panel and a slidable panel lying flush with the other panel when closed, a pin or projection on one panel engaging a cam slot or groove in the other or in a part carried by it so as to cause the non-slidable panel to tilt or be displaced transversely to allow the slidable panel to pass over or behind it. The upper part of an omnibus window 1 comprises three glazed panels mounted between bars 2, 3, the middle panel 4 being non-slidable but transversely movable and the outer panels 5, 6 capable of sliding over it, but lying flush with it when closed. The three panels are interconnected at their lower edges by the engagement of pins 16, 17 at the inner corners of the outer panels within slots 10, 11, formed in the underside of a bar 9 secured to panel 4, which is positioned in relation to the main frame by the engagement of an upstanding fixed stud 13 in a transverse slot 12 at the middle of bar 9. The upper edge of panel 4 is yieldingly pressed by a blade spring 21 against bar 2, so that when, e.g., panel 6 is moved inwardly by handle 29 and pin 17 in first travelling along an inclined portion 11a of slot 11 causes the panel 4 to tilt, the inclined face 27a of the vertical edge of panel 6 moves over the middle panel forcing its top edge outwardly against the spring. If. the other end panel is also moved panel 4 assumes a laterally displaced position parallel to the other two. The spring may be replaced by pins and slots at the upper edges of the panels or the middle panel may be mounted on parallel motion links. A channel casing 37 enclosing the spring has at each end a number of slots 32 and louvres 33, holes 35, 36 also being provided in the top flange of the panel and bar 2 so that air is extracted from the interior during motion of the vehicle.

Abstract: In acetylene generators of the type comprising a lower carbide container detachably fixed to an upper water container and having valve means for controlling the supply of water to the carbide container, three independent passages or tubes are <PICT:0637127/IV (b)/1> <PICT:0637127/IV (b)/2> <PICT:0637127/IV (b)/3> <PICT:0637127/IV (b)/4> <PICT:0637127/IV (b)/5> provided in the closed water container, one of which contains the housing for the water valve and extends through the water container into the carbide container, the second which constitutes the water levelling tube is open at both end and extends from outside the top of the water container down to the desired level of water in the water container, and the third is open at both ends and extends from outside the top of the water container to nearly the bottom of the water container, and is in communication with the first tube below and above the level of the bottom of the second tube to allow water to pass from the water container to the valve housing, and to provide an outlet to the open through the valve for any excess gas generated in the carbide receptacle.  The three tubes may be formed by using a central valve tube and enclosing same in or towards the centre of a casing so as to form two side tubes, one of which is the second water levelling tube and the other is the third tube for water admission and gas outlet. The three tubes may be assembled together, or the first and third tubes may be assembled together and the second tube in an independent position.  In Fig. 1, the water container 2 is above the carbide receptacle 1.  The central valve tube 16 constitutes the valve housing and is fixed in the centre of a casing 19 to form two side passages 17 and 18.  Passage 17 is the water levelling tube and extends from outside the top of the water container to the requisite depth inside.  Passage 18 extends from outside the water container to near the bottom, therefore to allow water to flow up through the bottom of the passage 18 through orifice 28 into the valve housing 16 and thence into the carbide container.  Excess gas generated can pass up through the valve housing 16 and escape through orifice 29 above the bottom of the water levelling tube 17 into passage 18 and thence to the atmosphere.  Figs. 4 to 7 inclusive are cross sections of varying arrangements of the three passages.

Title: Instrument for Phase Measurements on Microscopic Objects
Inventor: BEYER HERMANN
IPC: G02B21/14
Filed: 1966-05-26
Abstract: 1,150,624. Microscopes. CARL ZEISS JENA VEB. May 26, 1966, No. 23586/66. Heading G2J. In an arrangement for making phase measurements on microscopic objects a Mach-Zehnder interferometer 7, 10, is placed near the exit pupil of the microscope objective 4 or, as shown, near the image 8 of the exit pupil produced by an intermediate imaging system 5, 6, the interferometer either having glass wedges 9, 13, in one of the partial beams to deflect it by a variable amount or a diaphragm, not shown, conjugated to an illumination diaphragm 2, so that interference is produced between the two partial beams. As shown, the slit diaphragm 2 is imaged by condenser 1, objective 4 and intermediate imaging system 5, 6, at 8 which is thus the image of the exit pupil. Since any ray passing through the exit pupil parallel to the optic axis forms an image on the optic axis, and any ray inclined thereto at the exit pupil forms an image displaced from the optic axis by an amount depending on the inclination, variable deflection wedges 9, 13, cause the image produced by one partial beam of the interferometer to be displaced relative to that produced by the other partial beam. The images can be observed through a monocular or binocular eye-piece along either the direction 11 or 11'. A phase shifter 12 enables charges of brightness, or in the case of white light, changes in colour, to be made. A plane parallel glass plate 14 and a glass wedge 15 compensate the optical path length in wedges 9, 13, and phase shifter 12. If a wedge is exactly at the exit pupil, or image thereof, 8, there will be separation of the object images and not of the pupil but if the wedge is placed between the exit pupil and object image there will be separation of both image and pupil. By rotating the wedges 9, 13 in opposite senses about an axis not parallel to the axis of wedge 15 the image separation can be entirely or partly cancelled so that the exit pupil separation can be chosen independently of the image separation. For small objects the slit diaphragm 2 is replaced by an annular one and the wedge system 9, 13, replaced by an annular diaphragm conjugated thereto. If the object is sufficiently small and the second diaphragm sufficiently narrow, the light diffracted by the object is blocked almost entirely by the annular diaphragm in one partial beam, so that interference occurs between two wave fronts, one representative of the object structure and the other not representative. The measuring accuracy may be increased by a half-shadow plate 16 one of whose phase steps lies in the intermediate image 3' of the object and the equality of brightness on either side of the step is used as a criterion for adjustment.

Abstract: 1490260 TDM loop systems; conferences HASLER AG 3 June 1975 [17 June 1974] 23907/75 Heading H4K A loop highway system is provided with means for setting up conference connections, the system being of a type in which no central exchange is provided. Each telephone station is provided with a receive store 5, a transmit store 8, a decoder 9, control logic 7 and three registers 22-24, comprising a transmit address register 22, a receive address register 23 and an auxiliary address register 24. During a normal two party connection the transmit and receive address registers 22, 23 both contain the identity of the station with which communication has been established. A station B of two stations A and B in communication, can add a further station C to the connection by first depressing a hold key to cause the address of A to be stored in auxiliary address register 24 and registers 22, 23 to be cleared. A signal is also sent to station A to cause the address B to be erased from the receive address register thereat. Station B now sets up a connection with station C, on the establishment of which the registers 22, 23 in station C contain the address B and the registers 22, 23 at station B contain the address C. To complete the conference connection station B now depresses a conference button causing a signal to be sent to station C which includes the address A from register 24 at station B. In station B the address A replaces address C in the receive address register 23 and register 24 is cleared. Receipt of the signal from station B at station C causes the address A to replace the address B in the transmit address register 22 and a signal is sent from station C to station A to cause the address C to be set up in the receive address register of station A. A conference loop is thereby set up, which further stations may be added. The stations are further provided with means for ensuring that the speech from only one station circulates at a time round the loop, the means including an arrangement for comparing the signal level received at the station with that being produced by the microphone of the station. A speech switch at the station is operated should the speech level thereat exceed the level being received and a signal is sent on round the loop to the other stations of the conference to cause similar switches thereat to operate to cause signals received by them to be transmitted on to the next station in the conference loop, in addition to being supplied to the speech reproduction circuits of the respective stations. The speech signals will therefore be finally received back at the station which produced them where they are prevented from further onward transmission because of the position of the speech switch.
