Title: Apparatus for speed indication
Inventor: MARSHALL ARTHUR NIEMEYER
IPC: G01P3/10
Filed: 1968-02-20
Abstract: 1,221,246. Speed indicating. A.N. MARSHALL. Feb.20, 1968 [Feb. 20, 1967], No.8200/68. Heading G1J and G1K. Apparatus for speed indication comprises a time carriage 21 (guided by a rod 24) whose displacement from a zero position represents elapsed time, a distance carriage 60 (guided by a rod 43) whose displacement from a zero position represents distance travelled and controls (switches 100, 98) for selectively setting in motion and stopping the carriages 21, 60 beyond their zero positions to identify an average speed of a vehicle being monitored from a vehicle carrying the apparatus, the positions in which the carriages stop determining the speed indicating position of a needle 402. Both carriages can be returned to their zero positions but a latch 305 is provided to prevent return to zero of one carriage and enable checking of speed using the other. The needle 402 is latched by a member 415 and, when released by a button 403, is moved, under the action of a spring 414, relative to a scale 401 until contact is made between a lower leg 406 of a C-member 405 and a pin 65 depending from the carriage 60. The scale 401 is mounted on the carriage 21, on which the needle 402 and member 405 pivot about spaced axes. Sliding coaction between a pin 409 and pusher bar 410 moves their point of contact toward and away from the pivotal axis of the needle 402 to provide increased arcuate movement at higher speeds. A constant speed electric motor 33 controlled by the switch 100 may drive the carriage 21 through a screw 27 and half-nut 36 and an electromagnetic clutch controlled by the switch 98 may connect an odometer drive to a worm 55 to drive the carriage 60 through a screw 51 and screwthreads in an arcuate recess 61 of the carriage 60. The half-nut 36 Fig. 8, secured to the carriage 21 has a coil spring 40 in a recess engaging a ball 41 rolling in a groove 42. The carriage 21 can be moved manually back to zero position after rocking it about rod 24 against the action of the spring 40 whereby the threaded engagement between the screw 27 and nut 36 is broken. If a knob 300 has a flat 304 facing downwards a roller 301 on its shaft 306 is engaged by the carriage 21 when rocked about rod 24 and, by direct engagement of the shaft 306 with a bell crank arm 302, the carriage 60 is drawn back to disengage its recess 61 from the screw 51, allowing a spring 62 to retract it to zero position. If the knob 300 has the flat 304 upwards, a slot 305 in shaft 306 latches the bell crank arm 302 and prevents disengagement of the threads and retraction of the carriage 60. A laminated scale plate, Fig. 15 (not shown) may have graduation marks cut out of an opaque layer over translucent and transparent layers and may be illuminated by reflection from a buffed steel mirror 454 below a lamp 453.

Title: Improvements in and relating to liquid feeding and measuring apparatus
IPC: G05D11/03
Filed: 1960-03-10
Abstract: 879,500. Mixing liquids in flow. HYDRAULIQUE & URBANISME S.a.r.L., and PONSAR, Y. M. March 10, 1960 [March 10, 1959], No. 8547/60. Class 86  In an apparatus for supplying an amount of reagent proportional to an output of water to be treated, the reduction of pressure in a pipe is a function of the flow of water and is used to control the metering of the reagent. In Fig. 4 the pyramidal and cylindrical containers 30, 33 are connected by a pipe 32 and contain fluid sufficient to fill completely the pyramidal container 30: An air blower 36 creates increased pressure in the pipes 31, 37 and reduced pressure in the pipe 35 and above the liquid in container 33. The bottom 39 of the pipe 37 is at the level of the weir 41 over which passes a flow of water Q; any rise in the level of the water flow causes a rise in pressure in the pipes 37, 31 which drives an amount of fluid proportional to the cube of the pressure out of 30 units 33. As the lower end of pipe 34 is subject to atmospheric pressure, the pipe 1 transmits to the metering apparatus, Fig. 1, and reduced pressure proportional to the cube of the difference between the reagent, the level of which is controlled by steam 40; that is, to the square of the quantity of water Q flowing over the weir. The metering apparatus, Fig. 1, comprises a container 3 supplied by pipe 2 with reagent, the level of which is controlled by a float valve 4 and weir 9 which cooperates with a pipe 10 and cap 8 to form a siphon discharge; the lower end of the pipe 10 has a trap 12. When the pipe 1 is at atmospheric pressure the level N of the reagent is level with the top of the weir 9 and there is no outflow. When the pressure falls in pipe 1, reagent is fed at a rate q proportional to the square root of the reduction in pressure, and hence in linear relationship with the rate Q of the water flow. The proportion of reagent may be adjusted by means of the screw cap 8 the lower edge of which co-operates with the weir 9 to form a metering passage. In another embodiment of the metering apparatus, Figs. 2 and 3 (not shown) and applicable to reagent in the form of a suspension, a metering orifice supplies a constant quantity of additive consisting of reagent and dilating water in varying proportions. A constant flow of dilating water equal to the total capacity of the metering orifice is supplied to the apparatus, and a proportion depends on the reduction in pressure in the pipe 1 is removed by an apparatus similar to that of Fig. 1, the difference being made up with reagent. In a modification of the apparatus of Fig. 1, (see Fig. 5 not shown) the main flow of water passes from a constant level through a gate into a second container, the difference in the levels in the containers being a junction of the square of the quality flowing out of the apparatus. The pipe 1 is connected to an elevated container the pressure in which is arranged to vary according to the difference in levels.

Title: Improvements in and relating to the manufacture of condensation products from trimethyl-hydroquinone
IPC: C07D311/72
Filed: 1939-03-18
Abstract: 539,697. Coumarane and chromane derivatives. HOFFMAN-LA ROCHE & CO. AKT.- GES., F. March 18, 1939, No. 8708. Convention date, March 18, 1938. Sample furnished. [Class 2 (iii)]  Coumarane or chromane derivatives are obtained when the trimethylhydroquinone monoalkylene ethers obtained by the interaction of trimethylhydroquinone with halogenoalkylenes containing not more than six carbon atoms in the presence of acid-combining agents are first subjected to rearrangement by heating and the products then treated with acid condensing agents. The halogeno-alkylenes are of the formula hal.CH 2 .CH=CRR<SP>1</SP> ; if both Rand R<SP>1</SP> represent hydrogen a 2-methyl-5- oxycoumarane is obtained, but when both R & R<SP>1</SP> are alkyl, then a 2-alkyl-6-oxychromane results. The products are useful for the manufacture of therapeutic substances. According to the example, trimethylhydroquinone is heated with allyl bromide in the presence of anhydrous potassium carbonate and the resulting mono-allyl ether heated above 200‹ C. and then melted with pyridine hydrochloride, giving 2 : 4 : 6 : 7-tetramethyl-5-hydroxycoumarane.  The sample furnished under Sect. 2 (5) consists of 2 : 2 : 5 : 7 : 8-pentamethyl-6- hydroxychromane and is prepared in a similar manner to the product of the example above, but using, instead of allyl bromide, the γγ- dimethylallyl bromide obtained by treating γγ-dimethylallyl alcohol with phosphorus tribromide. The Specification as open to inspection under Sect. 91 is not restricted to the use of halogeno-alkylenes containing not more than six carbon atoms and includes a further example describing the condensation of trimethylhydro-. quinone with phytyl bromide in the presence of anhydrous potassium carbonate, followed by the conversion of the resulting monophytyl ether with al-α-tocopherol, by first heating in decahydronaphthalene under reflux and then treating with anhydrous zinc chloride while stirring. This subject-matter does not appear in the Specification as accepted.

Title: Mechanically set well packer
Inventor: CLARK EARNEST HUBERT
IPC: E21B33/129
Filed: 1960-03-14
Abstract: 924,231. Wells. BAKER OIL TOOLS Inc. March 14, 1960, No. 8910/60. Class 85. A well packer A adapted to be lowered into a well casing B on a tubing string D comprises a body 10, an expander 16 on the body, slips 12 adapted to be shifted by the expander longitudinally and outwardly of the body, and retaining pins 33 engaging the slips to prevent them being expanded but shiftable longitudinally of the body on rotation of the string to release the slips. When the packer is at the desired depth in the casing, the string and a mandrel 55 carrying the packer are rotated to the right. A drag device rotatably mounted on the mandrel remains stationary during this rotation and causes a left-hand threaded sleeve 38 to move upwardly carrying with it the pins which are released from the slips. On release, the slips are moved by springs 42 outwardly and downwardly along the expander to engage the casing (see Fig. 2). The string and mandrel are pulled to shear screws 17, 20, 24 attaching expanders 16, 19 to the body and slips 23 to the expander 19. The body moves upwardly under the pull to expand the slips 23 which also move upwardly towards the slips 12 to press a resilient packer sleeve 18 into sealing engagement with the casing and the body. The packer is set and cement may be pumped down the string and mandrel to discharge through ports 100 into the space beneath the packer. When the pull is removed from the body the packer remains set since a one-way lock device prevents-separation of the slips 12, 23. The string and mandrel are turned to the right to cause a nut 67, which is rotatable with but axially slidable on the mandrel, to unscrew from the body, and the mandrel is elevated to prevent flow through the packer by means of a valve head 32 engaging a seat 29. If it is desired to remove the string and mandrel from the packer, the string is tensioned to break the valve head from the mandrel at a weakened section 106, the valve head remaining on the seat to prevent upward flow through the central passage of the body.

Record cards are punched under control of program instructions stored in a memory 10. A particular program of instructions is selected by keyboard 14 and comparator 22 which gates out successive instructions as counter 21 is incremented. Each instruction is stored in a register 11. A card having each column punched with the binary equivalent of the column number is mounted on a drum driven in synchronism with card feed through the punch by an escapement mechanism. The binary column numbers are compared at 12 with a field definition number of the instruction in register 11 to control incrementing of counter 21. Decoder 13 selects the punch operation mode, e.g. skip, duplicate; an optical scanner, Fig. 5 (not shown), is controlled by X, Y and field size information to select information from a document for input to the punch via memory 10; the operation in progress or other information is displayed; and the field size information additionally controls entry of non-significant zeros before punching. Program entry is from punched cards (or magnetic tape) which may be sensed by the reader normally provided in such key-punch apparatus, the programs being stored in respective locations of memory 10. Manual and document entry.-Data may be entered from a keyboard or the document scanner mentioned above. Manual entry can be made while automatic punching is proceeding; and in this case the data is stored in memory 10 until the punching operation is completed. Document data enters memory 10 until scanning has been completed. The output of data from memory 10 is through a selector which directs the data to the punch directly or via an accumulator or the zero fill unit. The accumulator enables a check to be made on the sum of a series of entries.
