Title: Direction Indicator Systems for Road Vehicles.
Inventor: THORNLEY DEREK
IPC: B60Q1/38
Filed: 1966-12-21
Abstract: 1,199,576. Road traffic signals on vehicles; direction indicator switches. JOSEPH LUCAS (INDUSTRIES) Ltd. 14 Dec., 1967 [21 Dec., 1966], No. 57180/66. Heading G4Q. [Also in Division H1] In a direction indicator system for a road vehicle having a manually operable direction indicator switch 11 (Fig. 1), resilient means urging the direction indicator switch to its neutral position and electromagnetic means 26 operable on movement of the direction indicator switch to either of its operative positions for maintaining the direction indicator switch in its operative position, a cancelling switch 22, 23 operated in use by a part 34 moving with the steering wheel of the vehicle breaks the circuit to the electromagnetic means 26 on completion of a turn and means are provided for holding the operating member of the cancelling switch out of the path of the part 34 except when the direction indicator switch is in an operative position. When the direction indicator switch 11 is turned to give a right-turn signal, the movable switch contact 32 bridges contacts 12, 13 so as to supply the right signal lights 24 from a flasher 18. Also the movable contact 33 bridges contacts 15, 17 which energizes electromagnets 26, 27 and 28. The electromagnet 26 maintains the indicator switch in its operative position until a switch 22, which is operated by a projection 34 rotatable with the steering wheel, is opened on completion of a turn. The electromagnet 26 is then de-energized and the direction indicator switch is returned to its neutral position by resilient means not shown. The ignition switch 21 has to be closed for the turn signalling system to function. Steering cancellation switch.-The electromagnets 27 and 28 form part of the cancelling switch 29 (Fig. 2), and when energized move a plunger 37 against a spring 47 so that a resilient portion 43 on the end of the plunger is moved into the path of the projection 34 which is rotatable with the steering wheel. As the plunger moves the resilient portion 43 to its operative position the contacts 44, 45 are parted so as to open switch 31 and de-energize the coil 28. Alternatively the switch 31 may be formed as a slider carried by the end 42 of the plunger which engages a conductive strip in the inoperative position and rests on an insulator to break the circuit to the coil 28 in the operative position. The resilient portion 43 is spring biased to a central position and is angularly movable in either direction and operates movable contacts of the switches 22, 23 mounted on a rotary member 41.

Title: Detachable handle
IPC: A47J45/07
Filed: 1966-12-29
Abstract: 1,144,272. Detachable handle. A. W. SERIO. 29 Dec., 1966, No. 58140/66. Heading A4A. A detachable handle, for easy engagement with an integral extension 22 of, e.g., a casserole, comprises, as illustrated in Figs. 3 and 4, a body means 30 having an engagement portion, clamping means 80 of non-circular cross-sectional configuration movably supported by the body means, said body means including spaced guide means 70 and 72 (not shown) for engaging and guiding movement of said clamping means towards the engagement portion and into clamping position, actuating means (comprises essentially an elongated actuating rod 100) movably supported for engagement with said clamping means to move the clamping means into clamping position as shown in Fig. 4, and means permitting tilting movement (this is effected by the sloping surface 110) of said clamping means with respect to the guide means in a direction transverse to said guided movement in order to provide for positive clamping. Alternative forms of the clamping means 80 are shown in Figs. 11 to 14 inclusive (see respectively parts numbered 160, 170 together with 174, 184 together with 188 and 194 together with 198 and 202). Figs. 20 and 21 (not shown) illustrate another form of this type of handle to clamp on to, e.g., a casserole having a curved outer wall. Figs. 15 and 16 show a modification wherein a clamping member 220, which is substantially rectangular in cross-sectional configuration is moved into clamping position by actuating rod 210. When the rod 210 is moved into the release position as shown in Fig. 16 the clamping member 220 pivots into the position shown and the trunnion-like portions 222 drop into the lower parts of slots 224, while when the handle is moved into the operative clamping position shown in Fig. 15, the rod 210 moves to the left thereby moving the lower portion of clamping member 220 to the left causing it to pivot into the position shown.

Title: Lane counter for digital navigational computer system
Inventor: RAPP B E
IPC: G01S5/10
Filed: 1969-12-02
Abstract: 1,236,876. Selective signalling. NORTHROP CORP. 2 Dec., 1969 [1 May, 1969], No. 58873/69. Heading G4H. [Also in Division H4] In a system for detecting when a first signal gains or loses one cycle of phase with respect to a second signal, and for algebraically counting said cycles of phase change, the phase difference between the signals is determined repeatedly by counting relatively high frequency clock pulses, and each time a low count immediately followed by a high count, or vice versa occurs, it is assumed that a change of phase by one cycle has occurred and a position counter is incremented or decremented by one. The system forms part of a radio navigation system in which pairs of ground stations transmit identical signals to form notional hyperbolic lane lines. As described signals derived from the two ground transmitters are produced on lines 38 and 39, Fig. 2, so that a trigger 110 is on for periods corresponding to the phase difference between signals-these periods being referred to as "apertures". Only some apertures pass to the counting circuit 25, as selected by a circuit 24 and relatively low-frequency clock pulses 62, and those that do, open a gate 131 letting relatively high-frequency clock pulses 61 through to a two-decade counter 135, 136. At the end of every such count, a strobe pulse 127 sets a trigger 147 if the tens decade 136 registers 1 or less, or a trigger 148 if the tens decade registers 8 or more. If either of these events occur, one of two gates 151, 152, is primed so that if the immediately next count is either low (i.e. with a tens count of 1 or less) or high (i.e. with a tens count of 8 or more) respectively, one of two triggers 155, 156 is set by the next strobe pulse to decrement or increment a position counter, not shown. The aperture select circuit 24 functions to let one aperture through to the counter in response to each clock pulse 62, and to produce a strobe pulse immediately following the end of the aperture, and the surprising complexity of the circuit arises from the fact that the clock pulses 62 are not synchronized with the input signals.

Title: Photographic lighting method and apparatus
IPC: F21S10/00
Filed: 1973-12-20
Abstract: 1450544 Lighting assembly POLAROID CORP 20 Dec 1973 [2 Jan 1973] 59126/73 Heading F4R [Also in Division G2]  A photographic system comprises illuminating means, positioned adjacent a camera, for illuminating a subject to be photographed, the light having at least two separate and distinct paths so arranged that the shadow of the subject is not seen by the camera. In the arrangement of Fig. 1, a flash tube 18 and reflector 20 are mounted on a camera housing 12. A light directing assembly is formed by a pair of outwardly facing mirrors 24, 26 and a further pair of forwardly facing mirrors 28, 30. Mirrors 24 and 26 are separated approximately by the width of reflector 20. The subject being photographed is a head, of width W S , and at a distance D S  from the camera lens 14. The arrangement of mirrors splits the light from the flash into three distinct parts. The right hand portion is contained within an angle #, and bounded by limiting rays 40 and 42. The left hand is contained within an angle γ, and bounded by limiting rays 44 and 46. Rays 40 and 46 terminate at the point C on the subject face. Light rays 48 and 50 from portions # and γ respectively pass just right and left of the subject head. The shadow of the subject produced on the background 34 is thus hidden from the field of view of the camera by the area of the subject head itself. The central part of the light beam passes through the gap between the mirrors 24, 26, and is bounded by the limiting rays 36 and 38. These impinge on the subject head at points B and D. The mirrors are so adjusted that the illumination is uniform and shadowless across the subject face, which must be at an optimum distance from the camera, and the variables are related by the equation where W L  is the width of the light source and D L  is the distance of the mirror assembly from the light source. In the embodiment of Fig. 5 (not shown) there is no gap between mirrors 24 and 26, which abut each other. In this case the flash beam is split into only two distinct parts. As before, the background shadow is concealed by the subject head, and the mirror geometry may be configured so that the illumination is uniform across the subject face, the equation in this case being In a further embodiment, Fig. 12, a cross-shaped baffle 168 has a central opening for accommodating the camera lens 158. Four equal squareshaped light sources 160, 162, 164, 166 are mounted so as to be movable radially with respect to lens 158, so that varying proportions of the light from each source may fall on the subject, and the equation for the Fig. 5 arrangement is applicable.

Title: A method of forming a stack of laminations
Inventor: LEUENBERGER HANS
IPC: H02K1/06
Filed: 1968-12-16
Abstract: 1,200,279. Laminating metal sheets; jointing; shearing. H. LEUENBERGER. 16 Dec., 1968 [29 Dec., 1967], No. 59640/68. Headings B3A, B3J, B3V and B3W. A method of laminating sheets comprises laying a plain sheet on an underlying sheet 2 having at least one indentation 3 formed therein and using the indentation as a die to form a further indentation in the plane sheet, which further indentation mates with the indentation in the underlying sheet to connect the sheets together. The laminations are of iron and their surfaces are electrically insulated, the stacks of laminations forming magnetic cores for choke coils or transformers. The bottom sheet is punched out initially and the indentations are stamped by a male and female die. The second lamination is punched out and placed on the bottom lamination, which acts as a female die for the second lamination, the original male die being used again. The process is repeated until the stack comprises the required number of laminations. Alternatively the punching and stamping operations may be performed simultaneously. The indentations are alternatively in the shape of a symmetrical trapezium with an open base, Fig. 5 (not shown), and they may be formed in the sheet edges. The stacks of laminations may also be used for stators and rotors of dynamo-electric machines.

Title: Gear shaping machine
IPC: B23F5/16
Filed: 1973-12-31
Abstract: 1431610 Gear shaping STAVELEY MACHINE TOOLS Ltd 20 Dec 1974 [31 Dec 1973] 60187/73 Heading B3L A gear shaping machine having a work spindle and a cutter spindle and means for rotating the spindles simultaneously comprises means in the form of a crank and connecting rod mechanism 6, 7 for reciprocating the cutter spindles parallel to the axis of the work spindle and means displacing the cutter spindle transversely to the work spindle to adjust the depth of cut. In the embodiment described the cutter spindle with its supporting head 5 are subjected to a transverse cyclic motion in synchronism with the reciprocating motion whereby the cutter 3 on the spindle 4 shaves the gear workpiece 2 in one direction of movement but is displaced laterally in the opposite direction of reciprocation to clear the gear workpiece. The superimposed cyclic motion is effected by way of a cam 10 on the cutter spindle drive shaft 8, which engages a roller 11 on one end of a lever 12, the lever being pivotable about a fulcrum position which is secured to spring plates 14, 15 attached to the machine frame. The other end of the lever is attached by a further spring plate 17 to the spindle support 5. The support 5 is, in turn, supported on spring plates 20, 21 and is pivotable about a fulcrum region 18. The pivoting action of the lever and spindle support is not that of simple rotation about a pivot but, as a result of the spring plates action, is of a rotary pivotal deflection. Although in the embodiment described the reciprocation and cyclic motion is applied to the cutter spindle the various motions could equally be applied to the work-gear spindle or of motion related to both work and cutter spindles.

A slip ring assembly for a dynamo-electric machine comprises a number of (carbon) slip rings 1 each having n radially outwardly extending recesses in its inner peripheral surface (4, Fig. 1, not shown), and an insulating carrier 11 having, for each slip ring, n radial projections 2 or 8, each slip ring being disposed against its associated projection, and the axial spacing between the projections for adjacent slip rings being greater than the width of a slip ring. The projections are, except for those (2) at one end of the carrier, smaller in height than the recesses (4) in the slip rings, so that, during assembly, the slip rings can be pushed over the intervening projections into their required positions. The slip rings may be glued to the supporting surfaces of the carrier 11, these surfaces having depressions 10 into which adhesive or cement in tablet form may be placed during assembly, to be subsequently softened by heat to cause adhesion to take place. The projections 8 may have portions constructed as fan blades to assist in cooling the slip rings. Recesses 9 may be provided in the carrier to facilitate removal of the assembly from the machine shaft. Connection to the slip rings may be made by means of bolts 5, one for each slip ring, screwed into a threaded hole 7, in their associated slip rings and insulated from the remaining slip rings by insulation 6.
