Title: A book for spatial observation of sterioscopic images
IPC: G02B27/22
Filed: 1959-04-16
Abstract: 919,127. Stereoscopic image books. ARTIA. April 16, 1959 [May 14, 1958; Feb. 2, 1959], No. 12899/59. Class 97 (1). A book containing pairs of images on opposite pages for stereoscopic viewing using the principle of the mirror stereoscope, has said mirror mounted at the central hinged joint of a pair of resilient folding bridge members the remote ends of which are hinged one to each cover of the book, a thrusting bearing near each hinge acting between the book-cover and the underside of the bridge members to tension them into a continuous arcuate span to act as a page guide when the book has been opened to the required angle, the adjacent ends of the bridge arms having lugs which clamp the mirror in the correct operative position. In Fig. 1, the book-back 2 is rigidly connected to one of the covers 1 and hinged to the other cover 4. The bridge arms 9, 10 are hinged at 5, 6 and tensioned by the hinged arm 17, 18 in Fig. 4 which has a ball-bearing 19 engaging a recess 20 in the cover. Fig. 2 shows how the lugs 14 of the bridge arms clamp the pin 16 when the book is opened to hold the mirror rigidly in the correct position as shown by 13 in Fig. 1. When the book is closed, the hinged supporting members 18 fold away from the stop 21 and release the tension on the bridge arms and on the mirror which fold flat within the covers, the mirror fitting into a recessed portion of a spacing plate 23 which is used to compensate difference in thickness in stacks of pictures. Alternatively, the supporting members for the bridge may be in the form of wing-shaped hinged flaps which fold upwards against the underside of the bridge arms. Alternative to the pin 16 for clamping the mirror is a flat projection on the mirror mounting for clamping between the lugs.

Title: Apparatus for measuring the amplitudes of quadrature components of the fundamental of an applied voltage
Inventor: PAUL ROBERT JOHN ALEXANDER
IPC: G01R19/00
Filed: 1958-04-23
Abstract: 845,945. Measuring peak transient voltage and current. SHORT BROS. & HARLAND Ltd. March 20, 1959 [April 23, 1958], No. 12933/58. Class 37. Relates to apparatus for testing the frequency response of a circuit. e.g. a servo mechanism and for measuring the components of the output voltage of the circuit under test which are in phase and in quadrature with a reference voltage applied to the input of the circuit. In Fig. 2 a generator 10 supplies an input reference voltage V i  to a circuit 11 under test. The output voltage V o  of circuit 11, which can be expressed as a Fourier series, is applied to one input of a multiplier 12. Generator 10 also supplies two further reference voltages sin wt and cos wt in phase and in quadrature with V i , one or the other of these further reference voltages being applied by switch Sl to the second input of multiplier 12. With switch Sl in the position shown, the in-phase component of V o  is measured by opening switch S2, switch Cl is then closed by a relay the next time the reference voltage V; (or sin wt) rises through zero, and is closed again at the end of one cycle of V i . The output voltage of the Miller integrator 13 is then the in-phase component of V o  and is measured on a meter (not shown). Similarly the component of Vo in quadrature with V i  is measured by applying the voltage cos wt to the multiplier. Alternatively, both components may be measured at once by permanently connecting the two further reference voltages to separate multipliers having associated integrators and meters. For reference voltage frequencies above 5 c.p.s. the integrator may be switched out of circuit and the output of the multiplier applied directly to a meter reading twice the average value of the voltage applied. Specification 825,978 is referred to.

Title: Improvements in method of and machine for wrapping articles
IPC: B65B51/02
Filed: 1932-05-05
Abstract: 395,483. Wrapping -machines. PACKAGE MACHINERY CO., 132, Birnie Avenue, Springfield, Massachusetts, U.S.A. May 5, 1932, No. 12968. Convention date, July 13, 1931. [Class 94 (i).] During the folding of the projecting end portions of a wrapper that has been applied around an article, an uncreased flap is formed which is flattened in two or more separate operations by applying pressure to different areas of the flap while sealing liquid is applied to different portions thereof. An article A, Fig. 1, is raised to the level of a table 30 bv plungers 31, 32, carrying with it a wrapper b into a pocket formed by members 33, 34, 35. A plate 36 advances to the right to turn up the rear depending edge c of the wrapper and a tucker 37 carried thereon makes the first end tuck. The article is now moved to position B ; the table 30 turns up the front depending edge d and a rail 38 makes the second end tuck. The end of the packet is now as shown in Fig. 11, owing to the proportion of the size of the members 37, 38 to that of the package, the upper and lower flaps e, f are not creased or flattened, the portions of the end tucks adjacent to these flaps being unconfined. At position C, a sealing liquid is applied to the flaps e, f. Resiliently mounted plates 40, 41, Figs. 4 and 12, slightly flatten the flaps, and a dauber 46 moves to the two positions, shown in broken lines in Fig. 4, to apply the liquid. The dauber comprises a casing or reservoir 54 pivoted to links 47, 53, and terminating in a plate 56 forming the core of a system of wicks 57 extending from the reservoir, which is supplied through a pipe 82. The extent of the exposed surface of wicks is limited by guard-plates. The link 47 is pivoted to a stationary bracket and the link 53 to a vertically reciprocable crosshead 50. A roll 61 on the crosshead engages a groove on the link 47 to cause the dauber to reach into the corner at the base of the flap at each applying stroke and to retract from the package in its travel between the two positions. At position D, Figs. 1 and 19, a plate 67 turns up the flap f against the end of the packet and the rail 38, while a second dauber 80, moving with the plate, applies a second coating of liquid to the flap e and flattens it against a plate 81. The edge 74 of the plate 67 is slanting so that at its lowest position it does not completely release the fold until the packet has been moved to the next position, and also tends to tighten up the overlapping portions of the edges c, d with which it contacts. The article is now passed along between side-plates by the succeeding articles into an oscillating holder 86 which turns it through a right-angle into position on a table 88 in front of a plunger 87. The plunger forces the packet between heating plates 89, adjustably mounted to exert a yielding pressure.

Abstract: 741,110. Angular bending. MULLER, K. May 11, 1953, No. 13085/53. Class 83(4). A tube-forming machine has four bending and seam folding tools reciprocable in paths, each of which forms the limb of a cross, to bend a sheet metal plate fed thereto around a central mandrel and to seam the plate thus bent. The machine includes, Fig. 1, four tool guideways 3 arranged in the form of a cross with a mandrel 4 at the centre, tools 5, 6, 7, 8 being reciprocable in the guideway 3 by linkages operated by cams on a hub 23 (not shown) rotatable by a gear 22 on a shaft 21. Metal sheets P are allowed to slide down a shoot 9 one at a time against a stop 11, on the guide 3 for the tool 7, by pins projecting into the shoot and suitably moved in and out by links operated by movement of the tool 6. The tools are moved, Figs. 6-12, so that the tool 6 folds the sheet up against the mandrel 4, the tools 7 and 8 complete the folding around the mandrel and, with the tool 5, interlock the opposed edges of the sheet to effect the seaming of the tube. The mandrel 4 which is divided in the horizontal direction is then reduced in diameter by the withdrawal of a wedge therefrom by a lever 41 (not shown) actuated by a cam 40 (not shown) and the formed tube is stripped off by a stripper 26 carried by a shaft which runs through the hollow shaft 21 and is reciprocated by a cam on the hub 23. In a modification, Fig. 14, the tool guides are mounted on a carrier plate 44 adjustable about a horizontal axis so that the guides may be arranged horizontally and vertically. A metal sheet, cut by a blade 58 from a strip fed to the machine through straightening rolls by rolls 57, is carried to a position below the mandrel either by a rotatable table 53 or an endless band 54. The stripped tubes are fed away by a conveyer 59 (not shown). The upper folding tool is in a forward position while lateral tools 63, 64 effect the bending of the plate round the mandrel, the upper tool is then withdrawn and seaming commenced. In a further arrangement, Figs. 17, 19, strip passse through straightening rolls 76, is ribbed by tools 82, 83, flanged and longitudinally grooved by rolls 77 and cut by a blade 81, the severed blank sliding down a shoot 72 to the bending means. The bending and folding tools are appropriately grooved to take the flange.

Title: Improvements in automatically operated electric fire alarms
Inventor: COCKRAM REGINALD WILLIAM JAMES
IPC: G08B29/04
Filed: 1955-05-06
Abstract: 803,219. Automatic electric fire alarms. PYRENE CO., Ltd. May 7, 1956 [May 6,1955], No. 13211/55. Class 118 (1). An automatic electric fire alarm comprises a detector head 2, Fig. 1, connected to a transmitter 3 and a receiver 4. In the normal position shown the grounded coil 13 of the receiver 4 is energized via switch 12, battery 1 and earth to hold off a switch 15 in circuit with an indicator lamp 17. When the detector head actuates, a switch 9 energizes a slugged coil 10 which breaks its own circuit from the battery 1 via switch 11 and also breaks the switch 12 in circuit with the coil 13. The de-energizing of the coil 13 makes the switch 15 which lights the lamp 17. When the coil 10 is deenergized the switches 11, 12 are re-made to again complete their circuits and re-energize the coil 13 which breaks the switch 15. Thus when alarm conditions prevail the lamp 17 is lit and extinguished intermittently, a steady light indicating a circuit break. In Fig. 3 several coils 13 each supplied as in Fig. 1 are situated in an intermediate station A, and each coil controls two switches, the switch 18 being normally made whilst the switch 19 is normally broken. The switches 18 are in series with one another and with a coil 21 of a receiver operating as in Fig. 1 but having its coil grounded through a battery. The normally broken switch 19 of each pair of switches is connected as shown to its own and adjacent switches 18. If one of the coils 13 is de-energized and energized cyclically it makes and breaks its switches 18, 19 to intermittently pulse the coil 21 at the central station B. The circuit giving the alarm call can be identified at the intermediate station A by its flashing lamp 22. In Fig. 4 the apparatus includes a monitoring system substantially the same as the alarm system of Fig. 1. The complete apparatus comprises three heads 2 (only one of which is shown) each fitted with a test switch 27, a switch 9 in the alarm circuit and a switch 91 in the monitoring circuit. Three receivers 3 are also provided, of which only one is shown, and a control-box 4 is fitted. The box 4 comprises two circuits 29, 29<SP>1</SP> supplied by batteries 30, and each circuit has lamps 17 or 171, relays 15 or 151, test switches 34 or 34<SP>1</SP>, a bell 31 or a buzzer 31<SP>1</SP>, and relays 32, 32<SP>1</SP> actuated by the coils 13, 131. In the alarm condition the coils 13 are deenergized so that the switches 15 and relays 32 are made to light the lamps 17 and sound the audible alarms. In a further modification, the transmitter 3 may be arranged normally to pulse the coil 13 and the lamp 17 and to give a steady current at alarm.

[Class 75 (ii)] In a pleated lamp shade the pleats are anchored at or near one end at two spaced locations leaving the free ends to be expanded until the longitudinal edges meet one another. The shade may be made from a sheet of paper, as in Fig. 1, outward folds being provided along the lines 10 below the zig-zag line 11 and inward folds along the alternate lines 12, while above the zigzag lines inward folds are provided along the lines 10 and outward folds along the lines 12. The sheet is then concertinaed and the folded edges 13, which may have been previously reinforced by adhesive tape 15, may be overstitched together, the sheet then being expanded until the edges 18 meet each other and are secured by press fasteners 19 in the expanded position. A hole may be punched in the sheet in the collapsed position to provide ventilation holes 20 for the lamp shade in use. The zig-zag line 11 may be formed of portions at right angles to each other, as shown, or of portions at an obtuse angle, and the sheet may also be folded along inclined lines so as to produce small outwardly directed pleats 21, Fig. 6, between large outwardly directed pleats 22 in the upper part and similar alternate small and large inwardly directed pleats 23, 24 in the lower part. According to the height of the zig-zag line and whether the upper part is smaller or larger than the lower half and where the pleats are stitched in the collapsed position, lamp shades of various shapes will be formed, some having a comparatively flat top with a conical surround, others having a cylindrical top and outward conical surround and others having a wide pleated top and short conical surround. Instead of being stitched at the top, the upper ends of the pleats may be provided with holes to receive two rings which provide a large opening at the top of the shade, the lampholder being secured to the rings by a spider.
