Abstract: 818,656. Date indicators. BENDIX AVIATION CORPORATION. June 19,1967 [Aug. 9, 1956], No. 19359/57. Class 106 (4). A calendar clock actuated by a daily pulse at 101 comprises a day register 61, month register 62 and year register 63 each advanced a step upon release of an assciated solenoid 71, 82, 94, with circuitry for causing the month register to advance a month and the day register to be reset to the first day at the end of each month in a manner appropriate to the length of the particular month, the circuitry including a switch 77 in the month register 62 for preparing a respective energizing circuit over a line 112, 111 or 105 at the end of a 31-day month, 30-day month or of February; a switch 89 in the year register for extending the February energizing circuit over line 105 either through contact 56 over lines 114, 110 in leap years or through contact 55 over line 104 in non-leap years; a switch 65 in the day register 61 for completing the prepared energizing circuit in the 31-day, 30-day, 29-day and 28-day positions respectively and a self-stepping motor 71 actuated upon completion of one of these energizing circuits to advance the day register to first day position. Upon receipt of the pulse at 101 at the end of the last day of a month a relay 103 is actuated through one of the energizing circuits associated with the last four positions of the day register over which the relay 103 is then held by a current source 120. At the end of this daily pulse, the solenoid 71 closes make and break contacts 113 and is immediately reactuated by current source 120 over the energizing circuits now interconnected by the relay closed contacts 106 (a-e), thus acting as a self-stepping motor to advance the day register to the first of the month. When the switch arm 65 moves off the 31st contact, the holding circuit breaks, releasing the relay 103 and the month solenoid 82, so that the months register 62 also advances. A further circuit is prepared by the switch arm 77 through contact 116 and line 117 to cause stepping of the year register when the month register changes from December to January.

Title: Method of and apparatus for purifying zinc metal
IPC: C22B19/32
Filed: 1933-07-10
Abstract: 412,775. Distilling zinc. NEW JERSEY ZINC CO., 160, Front Street, New York, U.S.A. -(Assignees of Ginder, P. M. ; Palmerton, Pennsylvania, and Hixon, H. G. ; Depue, Illinois, both in U.S.A.) July 10, 1933, No. 19468. Convention date, April 6. Addition to 395,602. [Class 82 (i).] In an improvement in the method described in the parent Specification for recovering zinc from mixtures of zinc with substances having higher and lower boiling points than zinc, such as lead and cadmium, a common source of heat is utilized for the distillation and for supplying extraneous heat to the rectification treatment for freeing the zinc from the contaminants with boiling points lower than zinc. The furnace structure shown in sectional plan in Fig. 2 is divided into two units by a partition 11, each unit comprising distilling retorts 13 with associated charging wells 36 and leadeliminating columns 24, and a cadmiumeliminating column 19 built in a compartment within the heating chamber 12 for the retorts. Heat is supplied to the cadmium-eliminating column through walls 16 and is regulated by shelves 45 on which may be built heat-insulating brick, and ports 46 which may be closed by loose brick. The front wall of the compartment contains removable brick to permit the heat regulating adjustments to be made. Impure zinc is charged from a ladle 38 through troughs 39. Each lead-eliminating column comprises a heat insulated cylinder containing saucers 28 for retaining pools of molten metal, and communicating with a heat insulated conduit 31 which extends along the entire side of the furnace and inclines slightly from each end to a point opposite the cadmium eliminating column. Dampers 35 control the admission of the vapour into the conduit. Zinc high in lead refluxes into the retort and lead-free zinc vapour passes into the conduit 31 and thence into the cadmium eliminating column through an elbow pipe 42. The cadmium-eliminating column consists of refractory trays 17 provided with ribs 19 of progressively increasing size and openings 18 in staggered relationship. Cadmium-rich vapour passes out through a dephlegmator 21 and refined zinc flows into a receptable 44. A lower row of retorts 14 serve as deflectors for the fuel gases flowing through the heating chamber.

Abstract: 1,204,276. Cleaning vehicle lamp glasses. FORD MOTOR CO. Ltd. 17 April, 1969, No. 19586/69. Heading A4F. A device for cleaning a vehicle lamp glass comprises means for moving strips 1, 2 relatively to one another around the periphery of the lamp glass to actuate wiper blades 5 so carried by the strips that relative movement of the strips causes each wiper blade 5 to sweep over an area of the lamp glass, the blades 5 being constructed and arranged to be around the periphery of the lamp glass when inoperative. In the illustrated embodiment each wiper blade 5 is pivotally connected to the strip, 1 and has a lug 9 extending into a gap 4 in the strip 2. By a manually operated or electric motor driven Bowden cable the strips 1, 2 are relatively displaced so that interaction of the lugs 9 and the strip 2 causes the wiper blades 5 to swing inwardly to positions 5a, the strips 1, 2 being then moved together through an arc of approximately 70 degrees and subsequently allowed to return by resilient means to their original positions. Means may be provided for directing a jet of water over the headlamp glass during the wiping operation.

Title: Electrolytic facsimile recorder apparatus
IPC: H04N1/40
Filed: 1963-05-17
Abstract: 1,043,821. Facsimile electrolytic recorders; protecting transistor circuits. HOGAN FAXIMILE CORPORATION. May 17, 1963 [May 31, 1962], No. 19615/63. Headings H3T and H4F. Carrier modulated facsimile signals applied a terminals 1, 2 pass through amplifier stages 7, 8 to a rectifier circuit 15, 16 and thence through emitter follower 24 and output transistor stage 25 to an electrolytic recorder 26, 31, the arrangement being characterized by the provision of an emitter feed-back resistor 35 which is included in circuits connected between the emitter and collector of both transistor 24 and 25. The circuit functions as a constant current source and delivers an output which is largely independent of the resistance of the electrolytic recording medium. Damage to stage 25 in the event of a short-circuit in the recorder is prevented by rectifier 45 which reduces point 42 nearly to zero potential. This reduces the current through a transistor 46 and correspondingly reduces the base bias of amplifiers 7 and 8 until they become non-conductive. The signal to the output stage is thus removed. Amplifiers 7 and 8 are also rendered non-transmissive by a pulse source 54 applied to the base of transistor 46 for the purpose of preventing inter-line synchronizing signals from marking the recording.

Abstract: 862,047. Current measurement; measuring instruments. SANGAMO WESTON Ltd. June 21, 1957 [June 22, 1956], No. 19639/57. Class 37. A load 10 (e.g. the motor of a machine tool) is connected to an A.C. source 11 through the primary of a current transformer 16 whose secondary is connected across a first diagonal of a modulator bridge 21 comprising four series assisting copper oxide or thermionic half-wave rectifiers 21-24. Adjustable and centre tapped potentiometers 32, 28 are connected across the first and second bridge diagonals, and their tappings are connected to the A.C. source through a limiting resistance to derive a polarizing voltage which on alternate half cycles drives alternate pairs of rectifiers 21, 23; 22, 24 to cut off and to conducting saturation respectively. A D.C. meter 33 is connected to the bridge through a variable potentiometer 34 in parallel with potentiometer 28, and is traversed by a unidirectional pulsating current of which the excursions are coincident with successive A.C. half cycles and which is shown to be proportional in amplitude to the in-phase component of the load current. Potentiometer 34 is adjustable to vary the sensitivity and particularly to set the meter full scale deflection to indicate maximum load current. Potentiometer 32 is adjustable to balance out the inphase current when the load is in an idling condition so that the meter reads zero and is able to indicate directly the working values of in-phase current.
