Title: Improvements in mobile applicators for dispensing liquids
Inventor: JOHNSTON DOUGLAS
IPC: A01M7/00
Filed: 1970-11-04
Abstract: 1299587 Spreading implements DEFCO Inc 4 Nov 1970 [19 Nov 1969] 52459/70 Heading AID [Also in Divisions El F2 and B2] A mobile applicator for dispensing liquids comprises a tank 153 for a liquid to be dispensed in air compressor 147 for maintaining a predetermined pressure in the tank, nozzle means 155 for spraying liquids released from the tank and a centrifugal governor operated diaphragm valve 20 actuated by movement of the applicator for controlling the volume of liquid sprayed so that it is proportional to the applicator speed and a constant volume per unit area is delivered. The control unit is driven through a flexible shaft 142 from a wheel 144 in frictional engagement with the applicator wheel 152. The control unit Fig. 5 comprises a centrifugal governor having weights 93 pivotally mounted on a spider 90 which in turn is mounted on a shaft 87. A cone 88 is mounted on shaft 87 and is driven from flexible drive 142 by a wheel 124. As the speed of the applicator increases the weights tend to rise and lift a cam plate follower 95 which, by means of a thrust plate 97, lifts a spindle 40 to open a valve 39 from its seat 36 which allows more of the spraying medium to pass from the inlet 77 to the outlet 78. Two diaphragms 41, 42 are provided in the control unit the former being exactly equal in area to the valve 39 and acting to balance the pressure acting on the valve 39 which tends to close it by receiving an equal force in the opposite direction. This allows the diaphragm 42 to balance the force provided by the rotating weights of the governor. The position of the wheel 124 relative to the core 88 can be adjusted according to a setting dial 128 so that a predetermined volume of spray per unit area can be selected. If the applicator moves so quickly that the control unit governor is at its maximum then the weights 93 contact the striker 101 of warning bell 100.

Title: Process for making carpets
IPC: D04H11/00
Filed: 1965-12-13
Abstract: Sheet material for use as the base of a pile fabric is made from scrap pieces of foamed polyether, polyester urethane, or rubber latex.  The scrap is granulated to a crumb size of about 5 mm. and placed in a mixing chamber having an atmosphere of dehydrated air or nitrogen. A two-component binder, preferably one or more glycols and one or more diisocyanates, is introduced into the chamber by a screw or gear pump, the two components being injected separately or simultaneously; a small amount of water may be added to generate carbon dioxide by reacting with the diisocyanate, thereby foaming the binder.  The mixture is placed in a cylindrical or other mould and compressed to one-sixth of its original volume.  It is then set by removing from the mould and storing at room temperature for several days; alternatively it is set whilst still in the mould by heating at 100 DEG  C. for 1 hour in a damp atmosphere. Finally, the block is sawn into a continuous sheet.ALSO:Pile fabric is made by electrostatically flocking nylon or rayon fibres on to a base sheet consisting of an agglomeration of small pieces of foamed polyether, polyester urethane, or rubber latex obtained from scrap material.

Abstract: 1393050 I C engine sumps DAIMLERBENZ AG 20 Nov 1973 [13 Dec 1972]  53839/73 Heading FIB [Also in Division F2]  Resonance of an engine, clutch and gearbox system, excited by vibrations generated at undesirable frequencies, particularly second order couples, by a five cylinder in-line injection-type internal combustion engine with asymmetric crank-shaft, are prevented by raising the natural frequency of vibration of flange-connected clutch and gearbox housings (7, 8) and 9, and the engine by stiffening the flange connections between the engine and clutch housing, and/or between the clutch housing and the gearbox. The latter connection is stiffened by inclining a half to four-fifths of the upper wall 15 of the gear casing 9 20 degrees upward towards the clutch housing (8), thus prolonging the clutch-gear housing flange connection upwards to an extent greater than that required for the internal space of the gear. The upper wall of the clutch housing (8) continues such inclination. Between the clutch housing (8) and the engine is a short intermediate housing (7) having a series of lattice-like or honeycomb ribs (21), Fig.6 (not shown), particularly around openings therein. The engine oil sump (4) is also provided at its rear wall with a honeycomb ribbing (19), Fig.5 (not shown), and an adjacent downwardly tapered rib (20), Fig.4 (not shown), at each side. These assist in bracing the engineclutch-housing flange connection.

Title: Seismic energy waveshape control apparatus and method
IPC: G01V1/387
Filed: 1970-11-12
Abstract: 1332927 Seismic source BOLT ASSOCIATES Inc 12 Nov 1970 [14 Nov 1969] 53957/70 Heading H4D A seismic source for underwater use comprises two chambers from the first of which gas under pressure is released abruptly into the water to generate an acoustic pressure pulse and from the second of which the gas is released through a restriction to provide a delayed after-flow of gas and so reduce the secondary pressure peak arising from oscillation of the abruptly released gas bubble. As shown, the two chambers 41, 42 are defined in a casing 54 by a barrier 44 having an apertured plug 46 which provides the restriction. When the source is "fired" by actuating solenoid valve 20 to reduce the differential pressure on head 30 of a spool valve 14, valve 14 accelerates from the closed (Fig. 1) position to the open (Fig. 2) position. Gas in chamber 41 is then abruptly released through ports 16, followed by a slower release of gas from chamber 42 via plug 46 and chamber 41. Casing 54 is detachable and contains removable sleeves 61-64 of various lengths (or is internally threaded, Fig. 4, not shown) so that the position of barrier 44 can be adjusted. This adjustment, and a change of the aperture size in plug 46, enable the generated seismic wave shape to be selected. The gas may be, e.g., air, N 2  or CO 2 , and its pressure may be enhanced by burning fuel therein. A second barrier may be provided in casing 54 to define a third chamber for further control of the wave shape.

Abstract: 1,274,620. Printers. GENERAL ELECTRIC CO. 19 Nov., 1970 [23 Dec., 1969], No. 54931/70. Heading G4H. In a font selection system for a cyclic printer having a plurality of fonts of characters, in which numbers representing required characters or character positions are stored for comparison with numbers representing type-faces for corresponding characters or character positions as the type-faces are cyclically brought into all potential printing positions, the system adds font-indicating numbers to the two sorts of numbers. As disclosed, type-faces are provided on respective fingers moved along the print line on a belt, there being two fonts. A finger counter is reset along with a font flip-flop as the beginning of the first font passes a predetermined point, clock pulses thereafter incrementing the counter to indicate the belt position, until a predetermined count is reached when the counter resets itself and sets the font flip-flop to indicate the second font. Each count of the finger counter is serialized in a shift register together with a bit from the font flip-flop and added to the required columns of the characters to be printed from a column memory, the sum in each case being compared with the identity of the character to be printed in that column, this identity coming from circulating storage including a shift register and containing a bit inserted in the shift register from a font selection flip-flop set according to the desired font. On equality, a pulse is routed to the appropriate hammer driver under control of the column memory. A print drum could be used instead.
