Title: Improvements in and relating to leakage indicators and protective cut-out arrangements for alternating current circuits
IPC: H02H1/00
Filed: 1932-03-14
Abstract: 396,481. Indicating faults. BRITISH POWER RAILWAY SIGNAL CO., Ltd., GLENN, S. L., and PIERCE, E. E., Windsor Works, Slough. March 14, 1932, No. 7565. [Class 37.] A leakage indicator for alternating current circuits, which may also control protective cutout arrangements, comprises a defiectional type instrument with a movable element 4, control coils 7, 8, and a graduated scale 6 with centre zero, where the effect of the control coils is to neutralize each other, the coils 7, 8 being energized from the respective line conductors 1, 2, so that leakage on either line produce a deflection of the pointer 5. The movable element 4 may be arranged to actuate contact members 15, 16 in an auxiliary circuit including visible or audible devices 23, 25, 27 for indicating normal conditions or a predetermined degree of leakage in either conductor. The movable element may also co-operate with contacts in a relay circuit for operating isolating switches for the defective conductor. To make the device more sensitive, the movable element may include a winding 10 connected across the line conductors. In a modified arrangement, the coils 7, 8 are connected to the line conductors through transformers. In a further modification the indicating devices are controlled through relays, the windings of which are in shunt with the control coils 7, 8.

Title: An improved instrument for determining the latitude of the place in which it is used
IPC: G01C21/02
Filed: 1929-03-08
Abstract: 329,732. Ross, J. March 8, 1929. Latitude instruments.-An instrument for finding local latitude consists of a semicircular board a marked with a scale of dates and a semicircular board b marked with a scale of angles and attached to the board a by an extended pivot d acting as a shadow pin. The boards a, bare mounted on a pedestal c and are brought into the meridian plane. The board b is turned about the pivot d until its diameter lies over the graduation on the board a corresponding to the date at the time of observation, and the graduation on the board b which is covered by the shadow of the pin d at noon is then the desired latitude.

Title: Packaging material register control
Inventor: MILLER ROLAND EARL
IPC: B65B41/18
Filed: 1966-02-22
Abstract: 1,069,705. Packaging machines. NATIONAL DAIRY PRODUCTS CORPORATION. Feb. 22, 1966, No. 7628/66. Heading B8C. A packaging apparatus comprises means for sealing a covering sheet with a series of integral surface markings to an interconnected series of cups filled with material such as food product and means for detecting and compensating for the registry of the surface markings with each of the cups. As described, a continuous strip of thermoplastic material (21), (Fig. 1, not shown), is fed into a forming station (39), where the strip is first heated between vertically reciprocal heated members (96) and (98), (Fig. 6, not shown), and then formed, between vertically reciprocal blowpipe (115) and mould (117), into pairs of side-by-side cups (23). A raised rim (30), (Fig. 3, not shown), surrounds the mouth of each cup (23), thereby forming a groove (31) between successive adjacent cups. The formed cups are next moved to a blanking mechanism (145), (Fig. 12, not shown) which punches out a portion (147), (Fig. 2, not shown), between the side-by-side cups to facilitate subsequent opening of the sealed package. The cups are subsequently filled with jam or jelly etc. at a feeding station (43), (Fig. 1, not shown), whereupon the filled cups are covered with a covering sheet (33) fed from a roll (Fig. 8, not shown) and heat sealed, by vertically reciprocal sealing (189) and cooling units (191), at the raised rims (30) of the cups. The cover sheet (33) has surface markings (35), (Fig. 2, not shown) and equally spaced indicator marks (167), one of which is in alignment with a photoelectric cell (207), (Fig. 8, not shown), when the surface marking (35) is in registry with one of the cups to be sealed. When the photoelectric cell (207) detects the misalignment of the indicator mark (167), a relay is closed to actuate the downward movement of a plate (177), attached to the sealing unit (189). The plate (177) engages the cover sheet (33) tucking it into the groove (31) thereby advancing the cover sheet by a small increment, this operation being repeated during successive sealing operations until the indicator mark (167) is once more in alignment with the photo-electric cell (207). The filled and sealed cups are finally moved to a trimming and severing station (47), which removes the excess portions of the border flange (Fig. 1, not shown) and separates the two side-by-side packages from one another by knife means (283). SeVeral strips instead of a single strip of material may be formed into the parallel rows of cups.

Abstract: 1,269,155. Seaming non-metallic sheet material. PHILIP MORRIS Inc. 23 May, 1969 [20 June, 1968], No. 8135/71. Divided out of 1,269,154. Heading B5K. [Also in Divisions B3 and F3-F4] Two bodies 100, 102, Fig. 1A, are joined in captive, independently rotatable assembly by telescopically interfitting at least a portion of a projecting means 104 on the body 100 in a cavity 106 in the body 102, spinning one of the bodies relative to the other while simultaneously applying pressure to maintain surface contact between the bodies to render at least a portion of the projecting means 104 soft so that it flows against and into the cavity 106, and terminating the application of pressure while continuing the relative rotation between the bodies 100, 102 until the softened portion of the projecting means 104 solidifies within the cavity 106. In the embodiment shown in Fig. 1A, the projecting means 104 is in the form of an annular skirt and the cavity 106 comprises an inclined undercut annular groove. Relative rotation between the bodies 100, 102 is produced either by holding one and spinning the other or by rotating the bodies in opposite directions. A lubricant may be applied to the surfaces of the groove 106 either before or during spinning to prevent adhesion of the parts while the deformed skirt 104 is solidifying. In a second embodiment, Fig. 2A, the projecting means comprises a hollow tubular boss 212 and the cavity comprises a groove 216 having a projecting shoulder. In another embodiment, Fig. 3A (not shown), the projecting means comprises a hollow tubular boss (221) and the cavity comprises an undercut annular groove (223) inclined oppositely to the groove 106 of Fig. 1A. In a further embodiment, Fig. 4A, the projecting means comprises a solid cylindrical boss 231 and the cavity comprises a counter-bore 233 having a conical base. In a modification, Fig. 5A (not shown), the counterbore (243) is undercut at (244) to form a shoulder. In a still further embodiment, Fig. 6, the projecting means comprises an annular skirt 251 on a body 250 which also has a bore 252. The cavity 256 is formed by a boss 254 having a flange 255 thereon. In an embodiment for joining a grip member 12 and a control knob 14 of a razor, Fig. 7A, the projecting means comprises an annular skirt 120 and the cavity is formed by a cylindrical boss 122. Upon relative rotation of the member 12 and the knob 14, the material of the skirt 120 softens and flows into a groove 124, undercut at 126, in the knob 14. The invention is applicable to joining a plastics body to a metal body, a plastics body to a body of dissimilar plastics material, a metal body to a metal body, or a plastics body to a ceramic body. Specified applications are joining fixed and rotatable parts of castors, rollers or wheels for toys and providing seals for obstructing leakage from hydraulic and pneumatic devices, e.g. pump glands.
