Patent GB-675837-A (GB)
Title: Manufacture of magnetic record carriers
IPC: G11B5/64
Filed: 1951-01-05
Abstract: A method of depositing a magnetic coating on an electrically-conductive carrier comprises subjecting the carrier as cathode to at least partial electrolytic action in an aqueous bath which includes metal ions in a concentration in the range .2 to 1.7 N, cobalt ions in a concentration in the range .2 to 1.0 N and hypophosphite ions in a concentration in the range .04 to .2 N.  The action is not wholly electrolytic since deposition of metal and liberation of hydrogen are in excess of that to be expected from the flow of electric current.  For best results the bath concentrations comprise .84 N nickel, .84 N cobalt, .145 N hypophosphate, and in addition ammonium chloride in a molar concentration of 1.9.  The pH value of the bath lies between 3 and 4.2 and is preferably approximately 4.  Minor amounts of various metals such as iron manganese, magnesiu, zinc and lead may be added to the bath.  The hypophosphite may be in the form of sodium, potassium, or ammonium hypophosphite.

Abstract: 1,055,061. Transistor circuits. TRW SEMICONDUCTORS Inc. Jan. 7, 1964 [Jan. 8, 1963; April 23, 1963], No. 673/64. Heading H3T. A transistor amplifier is provided with negative feedback via an inversely-operated transistor so as to minimize the effects of temperature and radiation. Fig. 23 shows a common emitter amplifying stage 310 in which the emitter current is fed back to the base via an inversely-operated transistor 320, operating as a constant current device. The beta of the inversely-operated transistor 320 should be in the range 0À01-1À0. Fig. 21 shows a three-stage amplifier in which each stage comprises a pair of transistors as shown in Fig. 23, the inverselyoperated transistors 260, 260<SP>1</SP> having an additional emitter to which the output 265 is connected. The transistors 270, 280 of stage 2 are of opposite conductivity type to the remaining transistors. The collector of the inverselyoperated transistor may be left open circuit or fed via a high-impedance load. Equivalent circuits (Figs. 1A, 3A, 7A, not shown), are included. In Fig. 26 (not shown), an amplifier having a high pass characteristic is provided by including a low-pass filter (316, 317) in the feedback path. In Fig. 27 (not shown), the lowpass filter is provided by a capacitor connected between collector and emitter of a transistor (320). In Fig. 30 (not shown), an amplifier having a low-pass characteristic is provided by including a high-pass filter (308, 307) in the feedback path. An amplifier having a bandpass characteristic may be provided by the use in the circuit shown in Fig. 23, of a first transistor 310 having a higher cut-off frequency than the second transistor 320 so that negative feedback only occurs during the low-frequency region when both transistors are operative, giving a high gain over the frequency range when transistor 310 only is operative.

Title: Process for the recovery of zinc from zinc plant residues
IPC: C01G9/00
Filed: 1963-01-07
Abstract: A process for the extraction of zinc from zinc-zinc ferrite residue comprises leaching the residue in an oxygen-free atmosphere above the boiling point of the solution at atmospheric pressure with H2SO4 in excess of that stoichiometrically equivalent to the zinc in the residue prior to leaching the residue under oxidizing conditions at 150 DEG -200 DEG  C. with H2SO4 and is characterized by the addition of a reducing agent selected from zinc sulphides, zinc powder, sulphur dioxide and hydrazine sulphate during the first leaching stage. Undissolved residue may be separated from the first stage leach solution, which may be reacted at a temperature between 150-220 DEG  C. with oxygen to form and precipitate basic iron sulphate.  In a preferred form, the process comprises leaching zinc-containing residue with H2SO4 containing-recycled zinc plant electrolyte solution in an autoclave using an atmosphere of sulphur dioxide at 40 p.s.i. and heating to 180 DEG  C.  The second stage leach may be effected using oxygen at 120 p.s.i. and the same temperature. Nitrogen or steam may be used in the first stage.

Abstract: PURPOSE: To exchange metallic molds with a pin in a short time, by fitting knock-out pins separately into a standard holder and a metallic mold to be fitted to the standard holder so that a knock-out mechanism which maintains a necessary overlapping area between the end face of each pin may be built in the equipment.  
     CONSTITUTION: A sheet material is placed on a lower die 14 fitted to a holder 10' under a removing- and fitting-free condition, and an upper die 12 fitted to a holder 10 under a removing- and fitting-free condition is pressed against the lower die 14. At this time, a knock-out pin 15 in the lower die 14, which is supported by a supporting spring 18 in such a way that the pin 15 does not extrude from the fitting surface at the time of fitting, is pushed down and presses the sheet material together with the upper die 12. When a product 5 is manufactured, the knock-out pin 15 is lifted and the product 5 is discharged from the lower die 14. When a press ram 2 is lifted further, a push lever 1 strikes a fixed rod 1' and the push lever 1 is pushed downward. Therefore, a knock-out pin 11 is pushed down by the lever 1 and the product 5 which adheres to the upper die 12 is removed from the upper die 12.

Title: Fitting structure of mirror

Filed: 1996-01-08
Abstract: PROBLEM TO BE SOLVED: To obtain a fitting structure of a mirror which can suppress optical path variation due to thermal deformation even when an optical box is fixed to a main body frame with a screw as usual. SOLUTION: A plane mirror 26 is held with a projection 36 and a leaf spring 38 so that it can slant. The reflecting surface of the plane mirror 26 is supported with a 1st arm 40 and a 2nd arm 46 positioned at an interval (d) with the 1st arm 40. The 1st arm 40 and 2nd arm 46 extend or contract in mutually opposite directions owing to temperature variation to generate moment of rotation in the plane mirror 26, which then slants to a specific direction. Therefore, even if the optical path of a light beam which is reflected by a polygon mirror is displaced owing to the temperature variation, since the mirror slants to the direction wherein the optical path is corrected, the light beam which is returned by the plane mirror 26 is made incident on a photosensitive body at a desired position.
