Title: Improvements in or relating to objective housings for photographic cameras
IPC: G03B3/02
Filed: 1958-02-17
Abstract: 850,545. Photographic cameras. LEITZ G.m.b.H., E. Feb. 17, 1958 [Feb. 21, 1957; Sept. 19, 1957], No. 5048/58. Classes 97(1) and 98(1) An objective housing for a photographic camera comprises focusing setting means and aperture setting means, a common setting member being provided for individually operating both the focusing and the aperture setting means. As shown, rotation of a pivoted lever 17 in the direction of the arrow causes the toothed part 19 to mesh with a gear 21 on the periphery of a tube 22 to move the tube 22 axially of the objective; this motion is transmitted in suitable 'ratio - by means of a differential worm - to an inner tube 29 fast with the lens to effect focusing. Whilst the lever 17 is held relative to its pivot 18 in the position corresponding to the required focus, rotation of the lever about the objective axis rotates a ring 7 which - if linked to a further link 6 by a latch 5 - sets a diaphragm ring 15 by means of a pin 8 of the ring 6 engaging a further ring 9 which links with a sleeve 12 connected to a ring 13 which meshes with the diaphragm ring 15. In a further embodiment, a manually rotatable sleeve coaxial with the lens axis is normally spring urged against an aperture setting ring for adjustment thereof, but is axially movable to link with a coaxial focusing ring, for adjustment of focus; alternatively, a lever is provided which in rest position is spring urged against the aperture setting ring, but which is rockable about an axis normal to the lens axis to engage a focusing ring; adjustment of either member being effected by rotation of the lever about the lens axis. In a final embodiment, the lever has a longitudinal extension which engages an axially displaceable collar such that pivoting of the lever causes the collar to link with either the aperture or the focusing setting ring.

Turning-gear.-A kick starter for motor-cycles &c. comprises a spindle 2 rotated by the kick lever 1 and provided with a spring-controlled plunger & slidable in a transverse slot 5 in the spindle 2 or an enlargement 4 and coacting with internal rat. chet teeth in a loose gear wheel 11, which meshes with a pinion 17 fixed on the shaft 18 of a changespeed gear. A fixed cam 15 holds the plunger 6 out of engagement with the ratchet teeth when the lever 1 is in the initial position. In the form shown, the spring 7 acting on the plunger 6 abuts against a plug 8 fixed in the enlargement 4. In a modification, the abutment 8 is slidable in the slot 5 and in the inactive position of the starter enters a recess in the cam member 15. On the actuation of the lever 1, the slidable member rides out of its recess and compresses the spring 7, which brings the plunger 6 into engagement with the ratchet teeth. The shaft 18 is connected to the engine shaft by chain gearing.

Abstract: 565,457. Bed-pans. KINGDON, D. E. March 23, 1944, No. 5411. Addition to 561,707. [Class 26] In a modification of a urine bottle, according to the parent Specification the sloping inlet tube 11, Fig. 1, is disposed externally of and overlies the bottle body 10 in reaching across the same from the front to the locality of the back. The body has a frontal roof portion raised above the delivery passage 13 of the inlet tube to provide an air trap 15, so that on tilting the bottle forward some of the air may escape through the passage 13 and allow any excess liquid in the delivery tube to pass down into the body. An air vent passage 23, Fig. 4, may be provided for the same purpose. The inlet tube may be separate from or integral with the body, and, in the latter case, the tube and body may have a common wall 12, Fig. 1. The inlet tube, when separate, may engage the body by means of a fast-pitch screw 18, Fig. 4, or other means of connection which allows the tube to be raised from its normal position to allow air to escape and excess liquid to pass into the body. The fast-pitch screw allows the inlet tube to be turned to project from the body to meet special requirements of the user of the bottle.

Abstract: 1,159,491. Centrifuge control system. AMERICAN FACTORS ASSOCIATES Ltd. 9 Aug., 1966 [29 Sept., 1965], No. 5658/66. Headings BID and B2P. Massecuite enters a vertically oriented, perforate or imperforate centrifuge basket (Fig. 3 not shown) through a butterfly valve 9 which is opened to a variable degree, against the action of spring (102), by a continuous flow of air delivered to valve actuator 10 through solenoid valves 6 and 7. The basket is rotated, through a belt drive, by an electric motor 2, and the motor current is monitored by an electronic circuit 5 (Fig. 2 not shown), which acts through valve 6 to vary the position of valve 9 and maintain a constant amount of massecuite in the basket. The same part of the circuit causes valve 9 to close completely if the current rises to a limit indicating overfilling of the basket. The current-monitoring transformer 4 saturates at 10% above full load to protect the circuit. The circuit also stops the motor and closes valve 7, to close valve 9 completely, if the current falls to a value which indicates that the drive belt has broken. Another part of the circuit allows for the heavy current taken when the motor starts and places the main circuit in a state to open valve 9 as soon as the basket reaches full speed. The centrifugal strainer illustrated has a perforated filtering surface in the basket and an adjustable partition which divides the filatrate into two fractions.
