Title: Improvements in or relating to lubricating arrangements for machines and mechanisms
IPC: F16N7/16
Filed: 1947-07-05
Abstract: 629,379. Automatic lubricators. STIBBE & CO., Ltd., G., STIBBE, E. V., and SMITH, B. July 5, 1947, No. 17787. [Class 12 (iii)] [Also in Group XXIV] An automatic device for periodically lubricating a machine comprises a four-armed Geneva disc 42, Fig. 5, having attached thereto an arm 41 hingedly depending from which is a spoon 13 which, in describing a path P delivers in turn, a predetermined quantity of lubricant from a trough 11 to each of four receiving cups 12, whence it is conveyed to the parts to be lubricated by tubes 27 ... 30 connected to tubes 5, 6 and holes 7, 8, Fig. 2. As shown for a knitting-machine, a constant oil level in the trough 11 is maintained by a "birdfountain" reservoir 9, Fig. 6, and is adjusted by grub screws 38 abutting against a flange 39 on the reservoir cover 36. To prevent flooding when the cover is removed, yet permit oil flow, the reservoir 9 has a spring-loaded valve 10 with a poppet head 10a which normally projects through a port at 34 and is held open by the rim 37 of the cover or by a spring 40. The lubricator is actuated by the reciprocation of a plunger 56, Fig. 2, housed in a stationary dial cap 3. This plunger oscillates a bell-crank lever 57 whose portion 62 is connected by a rod - 58 to a further bell-crank lever 53 in the trough 11 and having a spring-loaded pawl 54 engaging the teeth of a ratchet-wheel 49 to which is secured a disc 47 having a lug 48 to rotate the Geneva disc 42. Adjustments in the quantity of oil delivered may also be effected by using ratchet-wheels having a different number of teeth or by means of a stop 63 which enables more than one tooth to be fed at a time. The reservoir and trough, supported on an arm 16 extending from a boss 17 in a collar 18, are located by the engagement of a locking plunger 23 in a central boss 19. To facilitate servicing, the assembly may be swung away from its normal position by withdrawing this plunger whose handle 24 locks in a slot 25, 26 in the boss 17. The reservoir 9 and its cover 36 may be of transparent material.

Title: Automobile driving lamps
Inventor: HOLLIS ARTHUR J
IPC: B60Q1/076
Filed: 1970-04-14
Abstract: 1,254,814. Vehicle headlamps. G.T.E. SYLVANIA Inc. 14 April, 1970 [14 April, 1969], No. 17809/70. Heading F4R. [Also in Divisions G1 and H5] The attitude of a vehicle headlamp 1 is adjusted by means of an assembly comprising a pivotally mounted lamp housing 2, 3, and a stack of bimetallic discs 7 provided with electric  heating elements and arranged in a casing to deflect the lamp housing about its pivot by means of a push rod when the stack is heated and expanded by the heating elements. A spring assembly 9 returns the housing to its undeflected position when the heating elements are off. Operation of the heating elements and thus the assembly is controlled by a switch which is operated when the rear of the vehicle is loaded beyond a critical value. To avoid operation of the assembly due to changes in ambient temperature a gap is arranged to be present between the lamp housing and the push rod attached to  the stack of bimetallic discs when the heaters are off. The heaters are flat positive temperature coefficient resistance heater discs sandwiched  between pairs of bimetallic discs in the stack.

Title: Variable parameter electron beam amplifier and method of amplifying
IPC: H01J25/49
Filed: 1959-05-26
Abstract: 929,015. Space-charge wave tubes. ZENITH RADIO CORPORATION. May 26, 1959 [May 28, 1958; July 10, 1958], No. 17872/59. Class 39 (1). A method of amplifying signals comprises converting signal energy into transverse oscillations of the electrons of a beam, as in plane coupler 23, Fig. 3; subjecting the oscillating electrons, over a number of cycles of oscillation, to a field set up by means, such as curved pumping structure 25c, having an inhomogeneous component such as to subject them to changing transverse forces to expand the oscillations; and extracting signal energy from the expanded transverse oscillations, as by plane coupler 26. Preferably the fast mode is used so that beam noise can be stripped off, although the arrangement will operate with the slow mode. The pump frequency is chosen so as to constitute the idler as a backwardly-moving fast wave from which the noise can be removed by an upstream attenuator such as a lossy transmission line between the gun and the signal coupler; alternatively the signal coupler can also strip the idler noise. In Fig. 3 the pump field is of dipole configuration consisting of two curved plates 97, 98 energized by source 99 through coupling network 100a resonant at the difference frequency; in the degenerate case a simple tapped transformer may be used, Fig. 4 (not shown). The magnetic field strengths H 1 , H 2 , H 3  may be the same in the different sections, or different. In a further embodiment the unhomogeneous pumping field is produced by a series of conductors 103, Fig. 5, spaced in a plane opposite plane electrode 104 and fed alternately with oppositely phased voltages from circuit 100c. When the signal velocity differs from the cyclotron frequency, the phase velocity of the signal wave is finite, and the lumped structures must be replaced by travelling-wave couplers e.g. helical lines 118, Fig. 6, wound on opposed flat insulating sheets 117. In a further form, Fig. 7 (not shown), a series of opposed plates is disposed along the beam and connected alternately to opposite sides of the pump source and also to a D.C. source for electrostatic focusing. Quadruple forms of pump structure are described where the ideal parabolic shape is approximated by flat plates, Fig. 11 (not shown), helices, Fig. 12 (not shown). Where the phase velocity of the pump wave is finite the quadruple plates 195, Fig. 13, may be twisted as shown.

Title: Improvements in wide aperture radio aerials
IPC: H01Q19/19
Filed: 1965-04-28
Abstract: 1,088,175. Aerials. H. C. HUSBAND. April 28, 1966 [April 28, 1965], No. 17832/65. Heading H4A. In an aerial system in which radiation is directed by a primary paraboloidal reflector 2 upon a secondary reflector 3, and thence through an aperture 5 in the reflector 2 to a tertiary reflector 7, to be focused at a point 8 in a waveguide 9, means are provided for sensing geometric changes of the elements of the system and for compensating by moving and/or distorting the secondary and/or tertiary reflectors. As described, the tertiary reflector 7 is located at the elbow of a bent horn 6 and is mounted upon gimbals which permit tiltings about two orthogonal axes (A-A), (B-B), Fig. 2, lying in a plane perpendicular to the axis (C-C) of the reflector. Linear motions in the directions of the three axes are also possible, and the shape of the reflector may be changed by applying stress along the axis (C-C). Hydraulic plungers or electrically driven screw devices may be used to obtain these effects. The sensing means may comprise electrical strain gauges mounted, for example, on the support members for the secondary reflector 3. Alternatively, there may be a system of beams of light reflected from mirrors attached to various parts of the structure and falling upon photo-cells which produce signals representative of relative displacements. Thus, a light source attached to the rim of the reflector 2 may project a beam via an optical reflector secured to the reflector 3 back to a photo-cell device also attached to the reflector 2. The signals from the sensing means are suitably processed and are applied to control the means for adjusting the reflector 7, a closed loop servo system with damping being normally included.

A bellows pump or a compressed fluid operated bellows comprises a longitudinally extensible and collapsible corrugated tubular shell Fig. 1 of polygonal e. g. hexagonal cross-section and formed of six longitudinal extending laterally corrugated circumferentially spaced relatively movable elements 2 which together provide the hexagonal configuration; the gap 3 Fig. 2 between any two adjacent elements 2 being sealed by an interposed resilient member 4 which is correspondingly corrugated and the elements being prevented from deformation due to lateral forces by retaining members 9. When operating as a motor, brace plates 5 are located externally of the shell against the wall elements 2 in zones between adjacent valleys and crests defined by the corrugations. The plates 5 of different wall elements are separate from one another but those of any one element 2 are coupled together at their outer ends by channel members 6 which permit relative rolling movement between the associated pair of plates 5. The inner ends of each plate projects through and is resiliently sealed to a slot in the wall 2 and hooks over the hexagonal retaining ring 9. The ends of the shell are closed by plates one of which has a fluid inlet and exhaust port 13. When used as a pump the brace plates 5 are located within the shell as are the channel shaped coupling members 6; the returning rings being externally of the shell. In a modification the brace plates are dispersed with and the corrugations form alternately inwardly and outwardly facing folds (14a, 14b) Fig. 7 (not shown) each of substantially circular cross-section when collapsed. An annular retaining element (15) is located around the shell either in each outwardly facing fold or in each inwardly facing fold and is complementary in cross-sectional configuration to its fold when collapsed.
