Class 98(1) In a camera having a built-in exposure meter, means are provided for reflecting into the viewfinder the galvanometer needle of the meter, and also image field demarcations. The camera shown has a viewfinder objective 9 and eyepiece 10, into which eyepiece a second rangefinder image, from an aperture 12, is reflected via a mirror 13, pivoted lens 14, lens 15, and semi-transparent mirror 11. The image field demarcations are formed by apertures in a plate 21, and are reflected into the viewfinder by a mirror 25, lens 26, and mirror 11. (Mirror 25 has a central opening 27 to allow passage of the light rays for the second rangefinder image.) The galvanometer 4 of the exposure meter is rotatably mounted, and is coupled by a lever 41 to control the aperture and shutter speed. The galvanometer needle 31 projects into an aperture 30 in a stepped part 29 of a cover plate 28. The aperture 30 is spaced from the bifocai lens 16 at the same distance as is the demarcations plate 21, and its image is seen in the viewfinder through a cut-out portion 34 of the mirror 25. An inspection window 35 in the cover 2 provides illumination for the needle and aperture 30. On looking into the viewfinder eyepiece 10, there appear, in addition to the subject to be photographed, the field demarcations, and images of aperture 30 and the needle point. A fixed reference index is provided, to which the needle point can be adjusted by adjustment of the regulating members for the diaphragm aperture and shutter speeds.

IPC: E05B85/22
Filed: 1960-06-24
Abstract: 929,958. Latches; key-locks. WILMOTBREEDEN Ltd. June 13, 1961 [June 24, 1960], No. 22127/60. Class 44. In a door fastening device comprising a spring-urged sliding latch bolt 3, a bolt-operating lever 9 and a contactor lever 16 are mounted for pivotal movement about separate axes substantially parallel to the movement of the bolt and the contactor lever 16 is adapted for operation by a lever-type handle to release the device and is slidable transversely of its axis from a normal position in operative engagement with the bolt-operating lever to a locked position in which it is not so engaged therewith. As shown, the operating lever 9, pivoted about an axis 10, is formed with a portion 12 which extends in front of the bolt 3 and with a portion 13 which extends through a slot 14 in the bolt. The contactor lever 16 is mounted on a pin 17 for limited sliding movement which is determined by a slot 21 and which is indexed by a return spring 18. The upper end of the contactor lever overlies the portion 12 of the operating lever 9 with which it makes a pin-and-slot connection 22, 23, such that in the position shown, anticlockwise movement of the lever 16 effects similar movement of the lever 9 and hence withdrawal of the bolt 3. If-the lever 16 is raised from the position shown, so that the pin 22 moves into the upper part of the slot 23, the lever 16 is ineffective to operate the bolt. A link 27 of a remote control linkage makes a pin- and slot connection 25, 26 with the lever 16 and includes a peg 30 which is engaged by a part 29 of a lever type outside handle (not shown). The lever 16 is moved to the raised or locking position thereof by means of a forked lever 32, arms 33, 34 of which are arranged on opposite sides of the portion 20 of the lever 16, the lever 32 being rotatable by an inner knob to engage one or other of the arms 33, 34 with the portion 30. Ears 38 on the lever 32 engage a shaft connected to an outside key-operated cylinder lock. A striker 42 for the bolt 3 includes a portion 43 which is adapted to enter a guide portion 5 of a back-plate 1 and through which the bolt is projected by its spring 6.

Abstract: 964,744. Fluid-pressure brakes. BENDIX WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO. June 7, 1962 [June 28, 1961], No. 22139/62. Addition to 944,821. Heading F2F. The compressed fluid braking system of the parent Specification is modified in that additional valve means is provided including a valve element movable between a first position, wherein the pressure responsive valve is responsive to the pressure of the main source of pressure, and a second position wherein the pressure responsive valve is responsive to an auxiliary source of pressure. In one embodiment, Fig. 1, the additional valve means is a valve 120 of identical construction to the pressure responsive valve 92 shown in Fig. 2 of the drawings accompanying the parent Specification. The valve 120 is arranged with its lower inlet 136 connected to the pressure line 26 supplied by main reservoir 14 and its outlet 138 connected to the upper inlet of valve 92. The valve element of valve 120 is normally left in its upper position so that the circuit functions as if valve 120 were not there. Upon depression of the valve element, inlet 136 is disconnected from the outlet 138 and the latter is connected to upper inlet 134, which is fed with compressed air stored in an auxiliary reservoir 126 supplied from main reservoir 12 via a non-return valve 130. If, therefore, the pressure in the main reservoir falls below the predetermined value, causing the valve element of valve 92 to rise to its upper position and initiate an emergency spring brake application of the tractor brakes (and via relay valve 48 and emergency application of the automatic trailer brakes), the driver can release the brakes at will by first depressing the valve element of valve 120 and then returning the valve element of valve 92 to its lower position, in which it will be retained since the system pressure is again restored to a value higher than the predetermined value. In a second embodiment, Fig. 2, the valve 120 is replaced by a conventional double check valve 176 embodying a shuttle piston which automatically sets itself to communicate whichever of the two pressures, in the main and auxiliary reservoirs 14, 177, is the highest to the upper inlet of valve 92. The auxiliary reservoir 177 is normally disconnected from the associated inlet of the double check valve to conserve pressure in it, a pair of chuck members 192, 194 being provided so that when pressure in the main reservoir has fallen below the predetermined value, and resulted in an emergency brake application, the chuck members can be connected together to enable the brakes to be released.

[Also in Group XXVIII] In a turbo-alternator rotor having hollow conductors 9 for the passage of cooling water, these conductors are Roebel transposed to enable connections to inlet and discharge manifolds 27 to be made at the slot-bottom cross-over points. These manifolds consist of insulation hoses (see Group XXVIII) which lead into headers 6, 10 connected to inlet and outlet pipes 5, 12. The water enters through a stationary supply pipe 1 which passes along the hollow rotor shaft, its outer surface being threaded at 3 to prevent reverse flow, and discharges through an outer tube 13 to a volute 14 for recirculation. As shown in Fig. 3 (for a reduced number of turns and coils, by way of illustration) the alternate coils employ reverse handed transpositions, so that the paths between inlet and outlet headers are substantially of equal length. The leads to the slip-rings 21 or other excitation source may also be hollow for water cooling. It is stated that the coolant manifolds could extend between the slots.
