Title: Photographic camera
IPC: G03B7/00
Filed: 1959-05-01
Abstract: 911,824. Photographic cameras. AGFA A.G. May 1, 1959 [May 2, 1958], No. 15035/59. Class 98 (1). [Also in Group XL (b)] A camera having an automatic exposure regulating device includes transmission means arranged to derive movement from a manual release member and connected either to diaphragm or shutter speed setting means, both setting means being interconnected by means adapted, when the one of the interconnected means connected to the transmission means has reached the end of its range of setting movement, to lock the interconnected means together for common movement in which the second of the interconnected means enters a range of setting movement, the exposure regulating device being arranged to arrest the transmission means in a position in which the exposure set thereby corresponds to the measured light intensity, and the manual release member being arranged for continued movement, after arrest of the transmission means, to release the shutter. In the embodiment shutter speed setting ring 6 carries a pin 7 penetrating a slot 8 in diaphragm setting ring 5. Member 12 is displaceable in direction X by a knob 13 and is further connected to a photo-electric exposure regulator to move in direction X, as described in Specification 888,973, independently of the path of knob 13. A pin 16, attached to a shutter housing, penetrates a slot 17 in the diaphragm setting ring and the pin serves to anchor a return spring 18 connected by pin 19 to the diaphragm ring. As illustrated the diaphragm ring is set to the widest aperture and the shutter ring to the lowest speed. On depression of knob 13 the exposure regulator is brought into operation to control member 12 and shutter speed is varied by ensuring clockwise movement of pin 7. With high ambient light, member 12 is displaced further and pin 7, after reaching the end of guide 8, moves the diaphragm setting ring to adjust to a smaller aperture whilst the exposure time remains at its lowest value. After exposure, member 12 and therewith the shutter speed setting ring are returned to their original positions by spring 15, and the diaphragm setting ring is restored by spring 18.

Title: Acid calcium lactates and methods of preparing same
IPC: C07C51/41
Filed: 1934-05-23
Abstract: Acid calcium lactates in anhydrous crystalline form, containing 3 and 4 molecules of lactic acid to one atom of calcium referred to as CaL3 and CaL4 respectively, are prepared by crystallization from solutions containing an excess of lactic acid beyond the quantity combined with the calcium; the CaL3 being crystallized from ethyl alcohol, and the CaL4 from water, methylalcohol, acetone, or acetic acid.  The excess of lactic acid in the solution may be 5--15 per cent in the case of CaL3 and 50 per cent in the case of CaL4.  To produce CaL3, a solution of calcium lactate or carbonate in lactic acid may be evaporated to dryness and the residue dissolved in ethyl alcohol containing free lactic acid and crystallized, or the excess lactic acid may be added to the initial solution, in which case it need not be added to the alcohol.  To produce CaL4, a solution of calcium lactate or carbonate in water, methyl alcohol, acetone, or acetic acid containing a large excess of lactic acid is crystallized; for instance, lactic acid may be partially neutralized with calcium carbonate and the solution evaporated until it contains 30 per cent of water, when methyl alcohol is added and the mixture cooled for the crystallization, but if desired the evaporation may be stopped when the solution contains 50 per cent of water; or the water remaining may be 10--20 per cent, when methyl alcohol, acetone, or glacial acetic acid is added and the mixture cooled.  The Specification as open to inspection under Sect. 91 includes crystallizing the lactates from solvents miscible with water and lactic acid or an aqueous medium containing such solvents.  This subject-matter does not appear in the Specification as accepted.  Reference has been directed by the Comptroller to a document other than Specifications.

Abstract: 529,291. Thermionic valves; generating circuits. STANDARD TELEPHONES & CABLES, Ltd May 26, 1939, No. 15707. Convention date, June 28, 1938. [Classes 39 (i) and 40 (v)] A generator comprises an amplifier and a closed feed-back loop, the latter including one or more four terminal reactance networks, each proportioned to produce a phase shift of 90 degrees at the operating frequency which is stable with respect to variations of the network terminating impedances the networks together with the amplifying means producing a total phase shift of zero at the operating frequency. Fig. 6 shows an amplifying path in which network 12 produces a lead of 90 degrees and a feed-back path in which the network 13 produces a lag of 90 degrees. The phase shift of the network 12 varies slowly with frequency while the piezo-electric crystal CX in the network 13 produces a phase shift which varies rapidly with frequency. Alternatively the piezoelectric crystal may be in the shunt arm of the feed-back network in which case a grid leak is provided for the amplifier input Fig. 7 (not shown). A single valve amplifier may be used with the networks in the feedback path in cascade Fig. 8 (not shown) or a pair of valves in cascade may be used with the networks in the feed-back path Fig. 10 (not shown). In the latter arrangement the branches of the two networks are given the same magnitude so that the central impedance element formed by the adjacent shunt arms of the networks becomes infinite and may be omitted. Fig. 9 shows an arrangement in which the central impedance element LC2 is retained and an output in phase with the input is obtained and the two networks produce opposite phase shifts and the single valve 18 is arranged to produce zero phase shift by having a negative amplification constant. In this arrangement the output is connected to the space charge anode 20. U.S.A. Specifications 1,896,781 and 1,976,570 are referred to.
