Abstract: 727,138. Watches. HEWISON, D. K. Nov. 26, 1952 [Nov. 27, 1951], No. 27789/51. Class 139. A self-winding watch has its movement completely encased in a permanently hermetically-sealed envelope of plastic, which is transparent at least where it lies over the face, and has means operable through the envelope for setting the hands and for fine adjustment of the regulation device. The movement 4, Fig. 1, is. enclosed in a plastic envelope comprising two sealedtogether dishes 5, 6. A tube 7 is used for the introduction of an inert gas and thereafter sealed off. Hand setting. A shaft 9, Fig. 2, geared to the minute wheel carries a disc 8, the periphery, of which is milled to co-operate with two shoes 10, 10<SP>1</SP> pivoted respectively to levers 11, 11<SP>1</SP> which are pivoted at 14 and have projections which, under the pressure of springs, abut the interior surfaces of deformable patches 12, 12<SP>1</SP> of the plastic envelope. The ends 21, 21<SP>1</SP> of a lever 20 pivoted at 23 to a sleeve 25 retained in a housing 26 of the outer casing 19 abut the exterior surfaces of the patches 12, 12'. A stem 29 having a button 30 normally extends centrally through the housing 26, the sleeve 25 and the lever 20, but may be pulled out against the pressure of a spring 34 and tilted so that its inner end 31 engages either of two notches 33 in the upper edge of the lever 20. Depression of the stem 29 will then cause a clockwise or counter-clockwise movement of the lever 20 and the appropriate lever 11 or 11<SP>1</SP> will be rocked so that the shoe 10 or 10<SP>1</SP> will rotate the disc 8 counter-clockwise or clockwise to set the hands, after which the stem 29 is allowed to return to its original position. If the stem 29 is given a quarter turn a projection 38 at its lower end prevents its accidental outward movement. Regulating. The oscillation weight 43, Fig. 4, carries a plunger 45 normally urged outwardly by a spring 47 and having a wedge-shaped inner end 51 which can be brought adjacent the end 50 of an extension 49 of the index 40. The end 50 of the extension 49 and the end 51 of the plunger are visible through a hole 53 in the weight 43 and a transparent part of the envelope. The weight 43 can be so located and held by manually deforming the envelope that upon repeated depression of the plunger 45 the index 40 is moved in the desired direction to the appropriate extent.

Abstract: 753,586. Electroplating with copper. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Oct. 13, 1953 [Oct. 21, 1952], No. 28120/53. Class 41. To improve the smoothness and uniformity of the deposit in copper plating and to increase the plating current and hence the rate of plating, when using an aqueous cyanide electrolyte containing dissolved copper, 0.075- 3.0 grams of lithium are added to each litre of electrolyte. Preferably each litre of the electrolyte contains 15-112.5 grams of copper, sufficient alkali metal cyanide to complex the copper in solution and to provide 3.75-37.5 grams of free alkali metal cyanide and 15-90 grams of alkali metal hydroxide while it may contain 0-150 grams of alkali metal carbonate. 22.5-60 grams of potassium sodium tartrate may be present. The electrolyte may also include known plating improvers, viz. 0.03- 4.27 grams/litre of zinc and/or 0.75-75 grams/ litre of thiocyanate while whether these are included or not the known improved method of plating using a periodically reversed current may be employed, by repeatedly causing a plating current to flow for 0.2-300 seconds and then causing a deplating current to flow so as to apply from 10-90 per cent of the coulombs applied during plating. The lithium may be introduced as the hydroxide, carbonate, nitrate, citrate, or thiocyanate and the zinc may be added as the oxide, cyanide or thiocyanate or by anodic dissolution of a zinc electrode. The addition agents may be added to the electrolyte as dry mixtures containing lithium, zinc, thiocyanate and cyanide radicals. Reference has been directed by the Comptroller to Specifccations 630,165, 662,660 and 710,375.

Title: Improvements in latching devices for the doors of horizontal chamber coke ovens
IPC: C10B25/12
Filed: 1951-11-30
Abstract: 692,297. Coke oven doors. KOPPERS GES., H. Nov. 30, 1951 [Nov. 30, 1950], No. 28179/51. Addition to 689,056. Class 55(i) The coke-oven door latching-means of the parent Specification are modified so that if the springs are removed and the latch reversed, the latching means are manually operable if this becomes necessary. In the drawing, Fig. 1, lying to the right of the centre line shows the means arranged for spring-closing, whilst Fig. 2, lying to the left of the line, shows the latch 10 reversed and the spring omitted. A bearing 11 is secured within a flange 5 on the door plate 4 and is screwed to receive the latch screw 12 which is held against rotation in the bearing 11. A housing 23 is secured to the bearing 11, the walls of the housing having recesses which are engaged by ears 26 on a plate 20 which conveys the thrust of the springs 22 to the latch 10. A nut 14, having a squared or like end 16 to be engaged by a manually operable key or by the coupling of the mechanical latching means, has a shoulder 15 which is in thrust-transmitting opposition to a shoulder 18 on a bush 17 screwed into the latch 10. In Fig. 1, the thrust is applied, by turning the nut, through a ball bearing 19 to the compression plate 20 which is secured by screws 21 to the bush 17 which is thereby held against rotation. When the pressure of the latch has been released from the hooks 9, the subsequent disengagement of the latch, by turning it on the screwed bush 17, moves it slightly away from the oven. This movement relieves the latch from pressure against the flange 5 if the nut 14 has been excessively turned. When manual operation of the latch is required, the plate 20 is transferred to the other side of the latch which is reversed on the nut 14, the springs having been removed. The plate 20 again engages recesses in the housing 23 and the sealing pressure on the door is transmitted through the screw 12, by unscrewing the nut 14, against the ball bearing 19 and the shoulder 18.

Title: Measuring instruments
IPC: G01R19/32
Filed: 1977-07-05
Abstract: For electronic measuring instruments, the measuring mechanism of which exhibits a computer with a memory, an analog/digital converter, a temperature sensor and a time base device, an error compensation method is proposed which also uses the existing computer and memory. For this purpose, correction values of all components which can influence the measurement result, and of the reference quantities are recorded. In addition, temperature coefficients and aging-related change values of the reference quantities and components with respect to the time since the device was first used are detected and stored. All these values are taken into consideration by the computer in the calculation of the final measurement result. In this process, the correction values for the components and reference quantities are determined with the inclusion of all assemblies of the measuring instrument so that their errors are also taken into consideration.
Patent GB-647050-A (GB)
Title: Improvements in or relating to electrical protective arrangements
Inventor: RAYNER THOMAS ROBERT
IPC: H02H3/44
Filed: 1948-10-30
Abstract: 647,050. Protective cut-out systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Oct. 30, 1948, No. 28200. [Class 38 (v)] In an arrangement for controlling the switching-in of phasecomparison equipment of the carriercurrent, lock-in type, means is provided for detecting a fault in cases where the maximum permissible load under some conditions is greater than the three - phase fault current in other conditions. For this purpose, potentials dependent on the currents in the different phases are balanced in pairs, so that if the difference potential of any pair is sufficiently great, the control relays operate. Three current transformers RT, YT, BT supply the primaries of six transformers RF1, RF2, YF1, YF2, BF1, BF2 over a summation transformer SCT, the secondary outputs being rectified by bridges RR1, RR2, YR1, YR2, BR1, BR2, the outputs of which are connected to resistors RA1, RC2, RB1, RA2, RC1, RB2, respectively. Normally, the voltages in the pairs of resistors RA1, RA2, RB1, RB2 and RC1, RC2 balance and the control relays LS, HS are de-energized. On lack of balance, due, e.g. to a single-phase fault, one or other of the resistor pairs will be unbalanced and the relays will operate. One resistor of each pair is shunted by a condenser QA-QC so that on a sudden increase of current, the voltage across that resistor will build up more slowly than the other, so that operation will ensue. The secondaries of the transformers RF1 &c. are shunted by non-linear resistors RN1, RN2, YN1, YN2, BN1, BN2, the characteristics of which are different for the two members of a pair, so that a difference potential is produced at a predetermined overload. The low-set relay LS controls the phase-comparison equipment, but the actual tripping of a circuit-breaker cannot occur until the high-set relay HS operates. The phase-comparison equipment is connected across the secondary of transformer SCT whereby carrier current may be applied to the line.

Abstract: 427,026. Valve modulating - circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London, and DITCHAM, W. T., Tudor House, Broomfield Road, Chelmsford. Oct. 13, 1933, No. 28359. [Class 40 (v)] A valve modulating-circuit of the series modulation type is arranged to vary the average carrier intensity according to signal volume. The modulating-valve V4 is connected in series with the carrier wave amplifier V5 between the positive and negative high tension supply leads. The grid of the valve V4 receives a negative bias from a battery B4 and the modulating-signal is impressed on this grid from an input transformer T1 through resistance coupled amplifiers V1, V2. The output of the amplifier V1 is also fed through a potentiometer T to an amplifier V3, the output from which is applied through a full-wave rectifier D1, D2 to a resistance R4. Signal frequencies are shunted by a condenser C4, whilst variations in signal volume cause variations in the D.C. voltage across the resistance R4. As this resistance is in the grid circuit of the modulator valve V4, the average carrier strength is adjusted according to signal volume. In a modification, Fig. 2 (not shown), the output from the rectifier D1, D2 is amplified by a direct-current amplifier system before being applied to the grid of the modulator V4.

Abstract: 756,062. Rail vehicle retarders. COAL INDUSTRY (PATENTS), Ltd. Jan. 13, 1955 [Oct. 14, 1953], No. 28364/53. Class 103 (1). A rail vehicle retarding device comprises a ramp consisting of side angle members 6 and a cover plate 7 welded thereto, having renewable wearing strips 8 thereon, the ramp being pivotable about pins 11 at one end, so that it can be raised by springs 27, which act through rods 26 and a yoke 24 upon wedge members 17, into the path of the vehicle axles, the vehicle being positively lifted by engagement of the axles and ramp. The action of the springs 27 is arranged to be overcome by a fluid pressure operated piston 35 in a compressed air cylinder 37. The vehicle strikes a trip lever as it approaches the retarder device, thus opening a valve to admit compressed air to the cylinder to cause the piston 35 to move to the left so as to place the wedges 17 in a position in which the ramp is lowered. By suitably controlling the air flow to the cylinder it may be arranged that provided the vehicle is travelling below a predetermined speed, the ramp may be lowered clear of the axle path before the vehicle reaches the retarder.
