Title: Improvements in or relating to photographic shutters having built-in flash lamp synchronising devices
IPC: G03B9/70
Filed: 1940-08-26
Abstract: 537,209. Synchronizing flash-lamps and photographic shutters. KODAK, Ltd. Aug. 26,1940, No. 13470. Convention date, Jan. 26. [Class 98 (i)] The release trigger of a photographic shutter moves a contact which completes the circuit of a flash lamp before the shutter mechanism operates, in order to compensate for the time interval between the completion of the circuit and the flash. In the form shown, the release trigger 14 is formed with an arm 40 having a nose 41 which, when the trigger is operated, engages a spring contact 44 and completes the flash-lamp circuit, after which the arm engages a lug 39 on a pivoted latch 30, which is thus tripped to release the master-member 16, which then operates the blade ring. The time between the completion of the lamp circuit and the operation of the shutter may be varied by adjustment of an insulated pin 45, which may be spring-pressed into one of a series of holes in the shutter body, and which adjusts the position of the spring contact 44. The leads from the lamp circuit are connected to the shutter contacts by a plug 48, as described in Specification 535,754. A spring 23 urges the setting-lever 15 to its unset position, so that the master-member has not to overcome the inertia effect of the lever.

Title: A rotary churn washing machine
IPC: B65G65/23
Filed: 1945-05-30
Abstract: 600,671. Churn-washing machines. HARGREAVES (METALS), Ltd., and HARGREAVES, A. May 30, 1945, No. 13537. [Class 138 (i)] [Also in Group XVII] In a rotary hand-controlled churn-washing machine in which the churns are carried by a turntable through a number of positions in which washing and steam sterilizing are effected, a supplementary cistern provided with a float chamber is adapted to be put into and out of communication with a hot water tank through a valve that is opened and closed by connections from a hand lever which also imparts movement to a slidable bar by which valves controlling the water-spraying and steaming are controlled, the bar having a member that locks and unlocks a member on the turntable shaft, and being locked in the turntable locking position by a catch actuated by the float. After rotating the turntable to a given position, a lever 10 is moved to the " on " position shown, thereby closing a valve 3 through which a cistern 1 is supplied from a hot water tank, and opening spring-closed valves 16, connected to the spraying jets for a pre-rinse operation, admitting steam for a steaming operation and for actuating a water raiser 27 which takes water from the cistern 1 and delivers it to sprays for a " hot rinse " operation, and 26, connected to the jets for a washing operation. The lever 10 is attached to a slidable bar 15 which is also connected to a stop contacting a star-wheel 24 on the turntable shaft 25, so that the turntable is locked while the sprays are in action. The lever 10 cannot be moved owing to a stop 19 engaging a notch 18 in the bar. When the spraying and steaming operations are complete, the cistern 1 is empty and a float 21 in the float chamber 22 falls so as to release the stop 19, so that the lever 10 can be moved to the " off " position, thereby releasing the turntable, closing the spraying and steaming valves and opening the valve 3 so that the cistern 1 refills and the stop 19 is pressed against the bar 15 ready to enter the notch 18 as soon as the lever 10 is again moved to the " on " position..

Title: Improvements in and relating to the condensation of metal vapours
Inventor: QUINTIN ALBERT ANDRE JOSEPH
IPC: C22B19/18
Filed: 1960-04-20
Abstract: <FORM:0944590/C3/1> <FORM:0944590/C3/2> A surface condenser for metal vapour, e.g. Zn, consists of an enclosure surrounded by a jacket which contains a first cooling liquid or molten substance; a second cooling liquid is circulated through pipes situated within the first liquid and the heat abstracted by the condenser is varied by altering the level of the first liquid in the jacket and/or the amount of the second liquid circulating through the pipes.  The first liquid may be a molten substance or low melting-point metal, e.g. Pb, Cd, Sn, Bi, Na, K or an alloy of these, and the second liquid may be an organic liquid, e.g. diphenyltetrachloride, or pressurized water. Either or both liquids may be circulated to an apparatus for the utilization of heat.  The first liquid is maintained at a temperature above or below the said solidification temperature of the metal to be condensed according to whether the condensing surface is a metal or an inert refractory material.  Fig. 1 shows a condenser having an inlet 1 and an outlet 14 for any carrier gases. The condensing surface 3 is cooled by a first liquid filling an annular chamber 5 and heat is withdrawn from this first liquid by coils 7, 8, 9 containing a second liquid which are connected to a heat utilization apparatus (not shown).  Valves 71, 81, 91 regulate the amount of liquid passing through the coils and enable the temperature of the first liquid to be maintained constant at various levels.  Fig. 2 shows a condenser in which the annular chamber 5 is surrounded by further chambers 16, 17 both containing further first liquid and connected at their lower ends.  Cooling coils 8 contain second liquid and the level of liquid in the chamber 16 is varied by increasing or decreasing the gas pressure in the chamber 17 by means of a valve 18.  If the condensing surface is a refractory material the chamber 5 may be omitted.

Abstract: 1,075,419. Automatic control of current and voltage. INTERNATIONAL STANDARD ELECTRIC CORPORATION. March 30, 1966 [March 30, 1965], No. 13999/66. Heading G3R. In a voltage regulator of the series transistor type, the impedance of regulating transistors Q1 Q4, connected as a Darlington pair, is controlled by a negative feedback loop including Zener diode Z and transistors Q3, Q2, Q5 so that the output voltage is maintained constant up to a predetermined value of load current, Q5 being saturated. If the current increases further the output of voltage drops sharply causing Q2 to saturate and limit the current through Q1; the regulator then supplies a constant current and there is no feedback round the loop. A still further decrease in load resistance causes a further fall in voltage so that Q5 is lifted out of saturation reducing the drive to Q1, Q4 so that the output voltage falls rapidly to zero because of the positive feedback now provided. The output voltage is set by adjustment of potentiometer R4, and the short circuit current is determined by resistor R10 which is connected in series with an overload alarm lamp L across transistor Q1. A reset switch S is provided so that normal operating conditions can be restored when the overload is removed. A modified arrangement, using one transistor instead of the Darlington pair, is described with reference to Fig. 2 (not shown).
