Title: Improvements connected with head lamps for motor road vehicles
IPC: F21V17/00
Filed: 1927-05-27
Abstract: 301,334. Fitzgerald, F. W. V. May 27, 1927. Bulbs.-An electric lamp bulb, for use in a vehicle headlamp, is fitted internally with a screen which is fixed between the filament and the lower portion of the reflector, and which is slatted or pronged, or provided with slits or other apertures. The screen may be plane, or angular or semi-circular or otherwise curved in crosssection, and it may be made of nickel or other metal, and gilded or otherwise provided with a coloured reflecting surface on both sides. Bv this means the screen reflects part of the light projected downwardly by the source upwardly on to the upper portion of the reflector, or sideways on to another part of the screen and then on to the lower part of the reflector, so that the intensity of the downwardly directed part of the beam from the lamp is increased and that of the upwardly directed part is decreased. The prongs of the screen may taper towards the front of the-lamp and the screen may be bell-mouthed at its forward extremity. The screen may be arranged to have its greatest screening effect on the near side of the reflector, for which purpose the prongs on the near side may be longer, broader, or both larger and broader, or set at a different angle to those on the offside. In the form shown, an electric lamp bulb 1, Fig. 1, is fitted internally with a screen 3 provided with prongs 4. The screen 3 is attached to the ends of a semi-circular metal strip 5, Fig. 4, which is secured at its centre to a second, strip 7 which is welded or otherwise. secured to the lower limb of the bent rod 8 carrying the filament 2.

Title: Locking or braking devices for the slidable panel of a rigid sliding vehicle roof
IPC: B60J7/185
Filed: 1973-03-27
Abstract: 1361376 Sliding roofs W BAIER W BAIER L SCHOBER and E SCHLUMPRECHT 27 March 1973 [10 April 1972] 14592/73 Heading B7B [Also in Division E2] A vehicle roof slidable panel is provided with braking means whereby upon longitudinal movement of a rod 5 a braking member 9 pivoted thereto engages a cam surface fixed to the panel to cause a swing of the member 9 into enagement with a braking surface 12 on the roof. In a preferred embodiment, Fig. 2, brake rods 5 are mounted in guides on either side of a slidable cover 1. Movement of the rods from right to left relative to the cover 1 by actuating means (not shown) causes braking of member 9 in the form of a pivoted lever to engage a stop 4 fixed on the cover 1 and the brake element 10 is urged against a brake surface 12 on a fixed part of the roof such as the rain channel 2, Fig. 5. A spring 13 pivots lever 9 back from its braking position during subsequent return of the brake rods 5. The lever 9 strikes against a further stop 14, Fig. 4, when the cover is positioned beneath the roof aperture and a pin 17 on the lever 9 is guided in a slot 16 when the cover slides off the guides (not shown) before being raised into the closure position. In another embodiment, Fig. 6, a lever 19 connects articulated joint 8 to cover 1 which allows the guiding of rod 5 to be omitted and prevents backward movement of the cover during its raising movement into the roof aperture. In an alternative arrangement, Fig. 11, resilient toe 27 of lever 21 is caught on block 22 so that when the cover is raised it is simultaneously urged against the front edge of the fixed roof.

Title: Improved apparatus and process for manufacturing cement articles
IPC: B28B21/48
Filed: 1960-04-27
Abstract: 885,188. Making cement &c. pipes. PATENT AND LICENSING CORPORATION. April, 27, 1960 [June 22, 1959], No. 14807/60. Class 99(2). A process for producing cement products on a mandrel 23 comprises the steps of applying cement to a moving web 20 wetting the cement on the web, urging the web by the use of pressure against the mandrel and wrapping a number of layers of cement on to the mandrel. Asbestos fibres or fibre-glass or rock wool may be introduced into the cement. As shown, a moving felt 20 passes a water spray 21, any excess water being removed by pressure rolls, and below a hopper 10 which feeds a mixture of cement asbestos and sand on to the felt. The latter passes between a mandrel 23 and a roll 24, the pressure exerted between the madrel and roll causing water to be squeezed from the felt to wet the cement. A hydraulic lifting device 26 suspended from a rail 27 facilitates the removal from and the placing of mandrels in the pipe-making machine. The finished pipes may be removed from the madrels by applying air between the pipes and the mandrels.

Abstract: 583,363. Rectifying. WHITE, E. L. C., NIND, E. A., and JOHNSON, L. R. J. Sept. 10, 1943, No. 14918. [Classes 38 (ii) and 38 (iv)] An arrangement for feeding current or voltage intermittently to a load, which may be a delay network used to supply pulses to a magnetron, is provided with a rectifier adapted to derive a control potential from the current or voltage fed to the load which is used to maintain constant the current or voltage fed to the load. Fig. 1 shows a rectifier 1 feeding a load at terminals 3 from a transformer 2. The current feeding the load passes through a resistance 5 across which is connected the rectifier 6 as shown a diode, alternatively a selenium rectifier may be used. The rectifier is biassed so as to be operative only at a predetermined voltage and the voltage across the load 6b is applied through a smoothing circuit 6c to an amplifier. The output of the amplifier 7 is applied to a grid controlling the rectifier 1 so as to maintain its output constant. The amplifier 7 may be omitted if an appropriate connection is taken between the load 6b and the grid to the rectifier 1. As shown, the control is peak current operated, but alternatively the mean value of the current or the peak or mean value of the voltage may be stabilized by appropriate choice of the time constant of the rectifier circuit. The screen grid current in the controlled rectifier may be limited, Fig. 2 (not shown), by connecting a diode in series with a resistance between the anode and the control grid so that when the anode is negative the control grid is driven negative to cut off the electron current. In a modification, Fig. 3, for higher frequencies where the capacity in the arrangement described would produce a prohibitive phase shift, a series resistance 14 is provided in the screen grid lead to limit the screen current and a negative pulse is applied by diodes 15, 17 to the control grid to limit the screen current without necessitating the resistance 14 being of a large value. Fig. 4 shows an arrangement in which the screen grid is connected through an inductance 20 and a resistance 21 in series to a high positive potential and through a diode 22 to a lower limiting positive potential. In this way when the anode of the rectifier is non- conducting, an excessive rise in screen current is prevented and a rapid rise in the screen potential is ensured when the anode conducts by the fall of the screen current in the inductance 20. In a modification, Fig. 5 (not shown), the limiting diode 22 is omitted and the limitation is effected solely by the series impedance while the choke ensures rapid restoration of the screen grid potential.

Abstract: 553,635. Conveyers. VICARS, Ltd., T. & T., and CROSLAND, E. M. Nov. 24, 1941, No. 15085. [Class 78 (i)] Two substantially parallel band conveyers 4, 9 moving in the same or in opposite directions are connected by an angularly disposed conveyer 5 so that elongated articles, such as rows of biscuits 1, 2 arranged transversely across the conveyer 4 are transferred firstly to the conveyer 5 and then to the conveyer 9 in such a way that their orientation and also their relative spacing remain the same. The actual spacing after each transference will depend on the relative speeds of the conveyers. To facilitate transfer between the conveyers so that the articles remain face upward an inclined plate or bar 6 receives the oncoming edge of each article as it leaves the upper conveyer and a rotary brush may bear on the tail edge of the article till it drops.

In a method of reducing the number of electrical flaws in a coating of insulating material on a metallic foil, suitable for a transfromer winding, a double coated strip 72 is fed from a roll 70, which also grounds the metal foil to earth, between roller electrodes 78, 80 which are at a voltage sufficiently different from earth to break down and burn out most of the weak points in the insulating material. The treated foil is wound on a roll 92 via a system which ensures that the coil formed has a straight edge. An alternating potential may be applied to the roller electrodes, but the preferred embodiment uses a negative direct potential. Current flow from the voltage source is limited to prevent damage to the foil and provision is made for counting the burned-out and/or residual flaws. The cycle of coating and removing flaws can be continued until the insulation is of the required thickness.
