Title: Improvements in electrical recording apparatus
IPC: G01D15/08
Filed: 1950-10-14
Abstract: 710,411. Recording-apparatus. BOSCH GES., R. Oct. 14, 1950 [April 26, 1949], No. 25113/50. Class 106 (4) Apparatus for electrically recording the readings of measuring instruments comprises means for moving a recording surface of metal coated insulating material and a stylus attached to a movable pointer and supplied with marking current for burning a trace into the metal coating, the coating being applied by vaporization between 0.002Á and 0.3Á in thickness. An insulating recording strip 1, Fig. 1, to which a metal coating has been applied by evaporation is moved by means of two rollers 2, 3 of insulating material and carbon respectively and a current of from 15 to 30 volts is supplied to a stylus 8 attached to a pointer 7 from a source of supply 5 through a circuit including the carbon roller 3 and metal coating of the strip 1. To actuate switches or signalling means when a certain reading is attained a recording strip 10, Fig. 2, is subdivided uniformly by oblique, insulating lines 11 and electrodes 14, 15 are disposed in contact with the metal coating in predetermined positions so that a relay circuit is completed through the electrodes 14, 15 and metal coating and is broken when the insulating trace 13 burnt in the coating through the stylus 12 passes between the electrodes 14, 15 to give a signal. If a signal is required only when the reading is held for a predetermined time, a second pair of electrodes 16, 17 are provided in parallel with the electrodes 14, 15 at a predetermined distance corresponding to the required time. Each of the electrodes may comprise two wires in parallel in contact with the metal coating. Each of the auxiliary electrodes is wider than the width of the lines 11 and the pairs of these electrodes are so disposed that at least a part of each electrode of a pair is in contact with one and the same contacting strip at the same time. If the actuating force of the pointer is small, it is preferable to burn the metal by a spark discharge across a gap between the stylus and recording strip. If the deflections are rapid, a uniform record may be obtained by placing a spark gap or a semi-incandescent lamp in parallel with the stylus circuit.

Patent GB-632762-A (GB)
Title: Indicating device for the end of a page on typewriters
IPC: B41J29/44
Filed: 1947-09-17
Abstract: 632,762. Typewriters. CAMZI, J. P. Sept. 17, 1947, Nos. 25338 and 25339. Convention dates, June 1, 1945, and Sept. 29, 1945. [Class 100 (iv)] In mechanism as claimed in Specification 587,978, the rotatable stop is held in releasable engagement with the crown by at least one spring-loaded projection on the one member entering into recesses on the other, the notches of the crown being so shaped that if the platen tends to continue to turn, the fixed stop exerts a pressure on the rotatable stop which is greater than the said spring-loading to disengage the latter stop from the crown, and permits the platen to continue to turn. The construction described in Specification 587,978 is modified by the notches of the crown having each one inclined face. In another form, Fig. 13, on a sleeve 52 receiving the platen shaft is mounted a support 46 secured to the carriage and carrying the fixed stop and a movable guide 55 having a cursor 39. The notched crown 41 is driven from the shaft through pinions 54, 42 and has a radial seating for a spring 43 urging a ball 44 into notches 45 of an exterior disc 40 carrying a rotatable stop 37. If the platen continues to turn after meeting of the stops, the ball moves from one notch 45 to another to allow such movement. In another form of the warning bell arrangement, Fig. 15, the rotatable stop before reaching the fixed stop 47 rotates a member 48 against a spring 49 and thereby draws back the hammer 35 from the wall of the plate 5 along a slot 5a. As the rotatable stop continues it releases the member 48 and the spring 49 causes the hammer to strike the wall of the plate 5. On contact of the stops, an inclined plane on the stop 47 causes the supporting disc of the rotatable stop to move axially to disengaged position, thereby supporting the action of the notches of the crown. The index 16 has a projection held in one of the recesses in the disc 5 by a spring 16c, and on pressing on the index it can be displaced around the disc 5. The rotatable stop is fixed to its supporting disc by two screws displaceable in elongated apertures and fixed to regulate the position of the stop.

Abstract: 618,968. Hinges. MUNSTER SIMMS & CO., Ltd., and EVES, F. S. Aug. 24, 1946, Nos. 25354/46, 37612/46 and 15190/47. [Class 6S (ii)] [Also in Group XXX] An upright standard near the gunwale of a fishing vessel and supporting sheaves for a fairlead (see Group XXX) is adjustable angularly to permit the sheaves to be aligned with the rope. In one form, Fig. 2, the column 1 fits, at its lower end in a footstep bearing 2 below the gunwale 3 and passes through a split bush clamp 5 in which it may be vertically and angularly adjusted. A tapered portion SA of the clamp 5, engages a corresponding hole in a plate 4 countersunk in the gunwale 3 and the clamp is held against rotation by an arm 6 carrying a projection 7 which is held in a corresponding hole in the plate 4 by a bolt 8 screwed into a boss 9 on the plate. In another form a shackle 26, Fig. 6, having a removable pin 25 normally held in place by a spring urged pin 27 connects a ring 29 to lugs 24 upstanding from a deck plate 23. ' The ring 29 rotatably carries the lower end of a sleeve 30- which is detachably connected to the column 22 by means of cones 31 which can be forced by a bolo 34 to expand a split ring 33 against the inside surface of the hollow tube. The column 22 carries a flange 37, Fig. 8, of forked cross-section adapted to embrace an arcuate flange 38 of an inverted cup-shaped member formed in two parts 39 fixed on a plate 40 rotatable on the column 22. The plate 40 carries two tapered projections (not shown) adapted to be held in corresponding recesses in a plate 43 countersunk in the gunwale by a screw 45 to hold the plate 40 against angular movement. Thus the column 22 may be held against rotation by a screw 47 engaging complementary holes in the flanges 37 and 38. The shackle 26 permits the column 22 to be raised sufficiently to disengage the. projections holding the plate 40 when the screw 45 has been loosened, so that the column may be swung inwards to leave the rail free.
