Title: Improvements in means for feeding lubricating oil to the induction systems of internal-combustion engines
IPC: F01M5/00
Filed: 1946-11-23
Abstract: 619,171. Treating charge. BEST, D. M. C., and CLERK, R. C. Nov. 23, 1946, Nos. 34820/46 and 9746/47. [Class 7 (ii)] A device for feeding lubricating oil to the induction pipe comprises a chamber 19, Fig. 2, filled slowly from a reservoir 17 through a tube 1b containing a porous plug 21, and emptied at starting through a pipe 2 leading to the induction pipe, means being provided to prevent the flow of oil either into the chamber 19 or through the pipe 2 after starting. A pipe 3 permits air to be drawn through the pipe 2 after chamber 19 is emptied, the air entering at 22 and flowing through an annular passage 1a to the top of chamber 17, thereby preventing oil flowing to chamber 19 until the engine stops, when it is refilled in about the time the engine takes to cool. A duct 5 containing a porous plug 25. and controlled by a needle valve 24 may permit a small amount of oil to flow to chamber 19 when the engine is running, e.g. in a new engine. The plugs 21, 25 may consist of felt, porous bronze, silicate, or other filter-like material. In one modification the air entering at 22 passes through a filter in the reservoir lid, and in another the pipe 2 contains a cock operated from a choke valve to close after starting, the pipe 3 connecting chamber 19 directly to atmosphere. In Fig. 5 oil under pressure from pump 42 enters a reservoir 17c and feeds the engine lubricating system through a pipe 43, a ball valve 45 shutting off communication with a chamber 19c connected to the induction pipe through a pipe 2. When the engine stops, the valve 45 opens and the chamber 19c, vented to atmosphere through a duct 50, fills slowly through a passage 1c and porous plug 21c. A duct 46 allows oil to escape if the valve 45 fails to close when the engine is running. In Fig. 6 the device is integral with the engine sump 17D, a pipe 1D being connected to the throat of a venturi 53 in the inlet pipe of the oil pump. When running, the suction prevents oil flowing to the chamber 19D connected to the induction pipe.

The food may be prepared by (a) forming a sheet or ribbon of each portion by mixing the components of each portion, cooking (e.g. 190-300‹F.) the mixtures at superatmospheric pressure and extruding the mixtures into the atmosphere, (b) superimposing the sheets and (c) forming the superimposed sheets into a loaf-like mass so as to distribute the white portion in the red portion while the average temperature of the sheets is between 120‹F. and 170‹F. In step (c) a random pile of the superimposed sheets may be compressed or the superimposed sheets may be rolled. The food is preferably in the form of a roll which has an overlay of the white portion.

Title: Unsafe velocity detection system
IPC: G05B19/4063
Filed: 1970-07-20
Abstract: 1323315 Controlling velocity INFORMATION STORAGE SYSTEMS INC 20 July 1970 [18 July 1969] 35113/70 Headings G1A and G1N In an unsafe-velocity detection system for monitoring the velocity of a servo-positioned load, a train of pulses representative of the velocity of the load is compared with a reference pulse train such that any variation in the spacing of the "velocity" pulses produces a signal operative to alter the velocity of the load. The system is used in the data processing field to control the positioning of an array of magnetic read/write heads radially of a rotating disc stack. In this case, the load velocity increases from zero to a maximum at the centre of its traverse, then decreases to zero again Fig. 1 (not shown). The pulses representing the velocity of the load are derived from an elongated mask 13 having a pattern thereon, which is attached to the load, and a sensor arrangement 12, 14. As shown, the mask comprises transparent areas of equal width separated by opaque areas whose width increases towards the mask centre Fig. 3, (not shown). A photo-cell 14 receives light from a source 12 passing through the transparent areas, and as long as the mask is moving at the appropriate velocity for its position (see Fig. 1) the pulses from the photo-cell are equally spaced. These pulses are first shaped to a square wave form then supplied to a latch circuit 16, flipflop 17 and inverter 19. The latch output both resets the flip-flop and also triggers a ramp pulse generator or one-shot multi-vibrator 21, providing the reference pulses, whose output, via a threshold device 22, resets the latch circuit. If the photocell output pulses are regularly spaced, resulting pulses from the flip-flop 17 and inverter 19 reach an AND-gate 18 in anticoincidence, and hence no output is produced. If the pulse spacing varies, this situation no longer obtains and the resulting output from the AND-gate is fed back to the servodevice to adjust the speed of the load. In another optical embodiment, the mask is formed of absorbing material applied to a strip of reflecting material. The pattern on the mask 13 may alternatively be magnetically recorded, in which case the pulses are derived from a magnetic reading head. In a further embodiment, the mask is formed of conductive material and the pattern is formed by a series of slots suitably spaced along one edge. In this the sensing means is an eddy current probe.

Abstract: 907,248. Shuttle stop motion. WEBSTUHLBAU KARL - MARX - STADT VEB. Oct. 16, 1959, No. 35141/59. Class 142 (2). A shuttle stop motion for a loom in which shuttles can be picked simultaneously through two superposed sheds (in either the same or opposite directions) has the fingers 15 operated by the shuttle swells of the upper boxes mounted on a shaft 10 passing through a tubular shaft 9 carrying the fingers 14 operated by the swells of the lower boxes. At one end of the loom, the inner shaft 10 has an arm 16 carrying a roller 16a engaging an arm 17 on the stop rod 3, while at the other end of the loom similar mechanism is provided for the tubular shaft 9. When the sley is at the rear part of its stroke, rollers 7 ride on to fixed cams 8, thereby turning the stop rod 3 clockwise to free the arms 16 for movement by the shuttle swells to the position 16b. As the sley moves forward, a spring 18 turns the stop rod 3 to lift the daggers clear of the stop mechanism 5. If either shuttle fails to box, the appropriate arm 6 remains in the position shown to hold the dagger down.

Flux coated welding rods 2 are conveyed on an endless conveyer comprising belts 1, 1, supporting the rods 2 and a series of pairs of slats 4, 5, each pair of which forms a compartment for each rod 2. The size of the compartment can be varied (to suit different rod sizes) by moving chains 6, 6, carrying the slats 4, relatively to chains 7, 7 carrying the slats 5. This is done by moving a member (21) (Fig. 2, not shown). Thereby drive sprockets 15, 15 of the belts 7, 7 are moved relatively to the sprockets 14, 14 of the belts 6, 6. The depth of the pockets may be varied by raising skids (26) (Fig. 3, not shown), which support the belts 1. The rods 2 may be fed to a conveyer (37) (Fig. 4, not shown) which is similar to that described above, by a slatted conveyer belt (36) running at a slower speed than that of the conveyer 37.

Abstract: A catalyst especially suitable for the hydrocatalytic desulphurization of petroleum oils is prepared by passing a fluorine compound into a fluidized bed of oxides of cobalt and molybdenum supported on activated alumina at an elevated temperature so that fluorine is introduced into the catalyst.  In an example the bed is fluidized at 780 DEG  F. by cycling hydrogen and then tertiary butyl fluoride is introduced into the recycle gas. Alternatively, hydrogen fluoride may be used as the fluorine compound.  For autofining, the catalyst advantageously contains 2.5-6 per cent by weight of fluorine.  Specification 719,627 is referred to.
