Engraving.-In an engraving-machine, applic. able also for straight or circular dividing, the work is supported on a table b movable rectilinearly on a revoluble support a, and is engraved by a tool q mounted on a universally pivoted shaft p which is controlled either manually by passing a tracer t over patterns on a plate r, or automatically by a pattern cam j which is geared to the revoluble support a and engages a link k connected by a lever n and link o to the shaft. When the shaft is controlled manually the lever n is thrown out. The cam is mounted on a gear-wheel carried by a slide j' which is adjusted when a different gear-wheel is substituted. The shaft b passes through a sleeve x trunnioned in a yoke w which is adjustable in a guide v, revolubly mounted in a slide u, by means of balls v<1>. The slide is adjustable vertically on a standard m by means of a rack and pinion u<1>. By adjusting the slide u or yoke w, the patterns can be enlarged, reduced, or distorted; the pivot of the lever n may also be adjustable for this purpose. The plate r bears a number of patterns and inscriptions and can be turned to bring any of these into register with the tracer. In employing the machine for dividing, the lever n is thrown out, the tracer is passed over a line on the pattern,. and the table is moved rectilinearly or revolubly after each operation of the tool q. The table can be moved rectilinearly in two directions at rightangles by means of screws operated by micrometer heads i, i<1> respectively. The screw f of the head i engages a threaded depression in a lever which is held in engagement or released by means of a set-screw. The table is moved revolubly by means of a worm-spindle e which engages a, wheel d on the support a and is operated by a micrometer head.

Title: An improved method of and apparatus for measuring distances by means of sound waves
IPC: G01S1/72
Filed: 1956-02-24
Abstract: 809,337. Machine-tool details. HOFFMANN, E., [trading as HOFFMANN, WERKSTAETTEN FUER OPTIK UND PRAEZISIONS-MECHANIK, E.]. Feb. 24, 1956 [Feb. 26, 1955], No. 5886/56. Class 83 (3). [Also in Group XXXVIII] The carriage 43 of a machinetool is displaced a predetermined amount relative to the frame 47 thereof by generating a standing mechanical-wave 31 of sonic or ultrasonic frequency in a rod or tube 1 mounted on the frame 47, such that a sensing-hoop or hoops 23, 23<SP>1</SP> surrounding the rod 1 and attached to the carriage is moved along the rod when the carriage is moved, the carriage being displaced until a predetermined number of nodes or antinodes of the standing-wave has been recorded by a counter 28, Fig. 7, connected via a valve-voltmeter 26, Fig. 5 (not shown), to the sensing-loops. Alternatively the standing-wave may be generated in an optically-transparent doubly-refractive-medium which is illuminated with polarized light, the standing-wave producing a corresponding variation in the refractive index which is sensed photo-electrically. As shown in Figs. 6 and 7, a rod 1 of magneticmaterial magnetized by a coaxial-coil 14 is attached at its left-hand end to a cylindrical magnetic casing 2, and standing waves 31 are generated in the rod 1 by a quartz-transducer 3 energized from an oscillator 6. The casing 2 is slidably mounted on a guide-track 48 in the machine-frame 47 so that it can be displaced parallel to the axis of the rod 1 by a threadedspindle 51, the pitch of the thread being #/2 where # is the wavelength of the vibrations produced by the transducer 3. The spindle 51 is turned by a hand wheel 52 and carries a dial 53 graduated in fractions of #/2 which is projected optically onto a viewing-screen 54. The sensing-loops 23, 231, Fig. 8 (not shown), are mounted on an annular-disc 21, Fig. 6, mounted in a ring 16 slidable axially within the casing 2, and having a lug 44, Fig. 7, projecting through a longitudinal slot 15 in the casing 2, the lug 44 being attached to the carriage 43 which is moved by a hand wheel 46. The equipment is set-up by setting the dial 53 to zero by the hand wheel 52, and then adjusting the carriage 43 by the hand wheel 46 so that the loops 23, 23<SP>1</SP> coincide with a node. If the required displacement comprises an integral multiple of A/2 plus a fractional part thereof, the casing 2 is displaced by hand wheel 52 until the dial 53 indicates the required fractional part. The carriage 43 is then displaced by hand wheel 46 until the hoops 23, 231 again coincide with a node, the counter 28 is zeroed and the carriage 43 is then further displaced until the required integral number of #/2 displacements is indicated by the counter 28.

Abstract: 525,622. High-tension switches. FLURSOHEIM. C. H., DAVIDSON, G. W., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Feb. 23, 1939, No. 6101. [Class 38 (v)] Arc-extinguishing contacts 2 ... 5 in a liquidcontaining casing 1,.and a series isolator 16 are operated simultaneously or one after the other by a common mechanism. When the rod 22 is lowered to straighten the toggle 23, a spring 8 causes the floating lever 26 to pivot about its lower end whereby the rod 27 and crank 28 close the isolator. The lever 26 then pivots about its upper end and the rod 7 is moved against the action of spring 8, to close the. contacts 4, 5. The reverse process occurs in opening the circuit, arc-produced jets of liquid being forced through ports 21 in a partition located just below the liquid level. The breaks may occur in the same or different compartments and the casing 1 may be arranged vertically or slantwise. The parts 26 ... 28 may be mounted in a compartment such as 5 of Fig. 1 of Specification 506,857, and the breaker may be operated by oil-pressure as in Specification 489,336. By arranging for the rod 22, on fault, to rise through part only of its stroke and then fall again, one or more reclosures may be effected at the arcing contacts before permanent opening of the circuit occurs.

[Also in Group XL (b)] In a brake press, or other press, wherein a sliding guard 6 is actuated by a cam shaft 4 which also controls the operation of the ram and which is driven by a continuously running electric motor through an electrically controlled clutch and brake, switches 22 in the brake and clutch circuits are operated by a safety rail 21, which may be in sections, resiliently mounted along the bottom edge of the guard so that should the rail meet an obstruction, such as an operator's hand, the cam shaft 4 is brought to rest. Alternatively the brake and clutch may be controlled by a stationary photo-cell co-operating with a stationary light beam passing immediately above the work and under the lowest position of the guard, so that an operator's hand or other obstruction is forced downwards to interrupt the light beam. In operation, on depression of a foot switch the brake is released and the clutch engaged to rotate the cam shaft 4, whereupon cams 5 thereon lower the guard against the action of return springs 19. As the guard closes, a cam 7 opens an air valve to start the ram shaft 9 and a cam 10 closes a switch to energize a solenoid which holds the valve open. A cam 13 opens a switch to stop the cam shaft 4 after one revolution, while a cam 15 on the ram shaft 9 opens a switch to release the air valve after one stroke. The cams 5 allow the guard 6 to be raised rapidly by the springs 19 just before the work is shaped, to avoid obstruction of the work by the guard.

Title: Water distillation plant designed for automatic continuous operation
IPC: F28G1/08
Filed: 1961-02-20
Abstract: In a calandria-type, vertical tube evaporator, for use in the distillation of sea water, provision is made so that rods, mounted in the upper section of the evaporator, automatically pass down inside the tubes at predetermined intervals, so that the walls of the tubes are de-scaled without shutting down the plant.  The apparatus shown comprises two evaporators 10, 12, connected in multiple-effect, and a condenser 14.  The water to be distilled is pumped through heat exchanger 77, and used as coolant in condenser 14, before it is introduced into the evaporators through pipe 69. The water flows from pipe 69 through float valves 71 and 73 into one of the heating tubes 22 of each of the evaporators.  The heating jacket of evaporator 10 is supplied with superheated steam from coil 51, which is heated by burner 53.  Uncondensed steam, discharged from the jacket through pipe 60, is <FORM:0926744/III/1> mixed with distilled make-up water, supplied through valve 89, then compressed by compressor 59, and returned to the heating jacket via superheating coil 51.  The steam generated from the sea water, as it boils in the tubes 22 of evaporator 10, is passed through pipe 49 into the heating jacket of evaporator 12.  The steam generated from the sea water in evaporator 12 is passed through pipe 96 into condenser 14, from which the condensate (i.e. distilled water) is withdrawn through pipe 81.  The condenser is maintained under reduced pressure by means of pump 97. Most of the distilled water is withdrawn as product via heat exchanger 77 and pipe 82, and the remainder is supplied to valve 89. The condensate from the heating jackets of both evaporators is mixed with the distilled water in pipe 81.  Waste brine is discharged from the evaporators by pump 42.  The cleaning mechanism comprises two sets of rods 93, corresponding in number to the tubes in each evaporator, carried on plates 90, which are connected to pistons 95 by rods 94.  The rods are moved down into the tubes, at predetermined intervals, by compressed air supplied through pipe 98 and manifold 103, forcing the pistons down, while air under the pistons is discharged through manifold 99 and exhaust pipe 102.  The admission and discharge of air into and out of piston-cylinders 32 and 47 is controlled by solenoid valves 106, 107, 108 and 109, which are actuated by an electric clock and relay system (not shown).  When the tips of the rods have passed p  entirely through the tubes, the pistons engage switches 116, and this causes the solenoid valves to be de-energized whereby compressed air now forces the pistons upwards, so that the rods are pulled up out of the tubes.  The cleaning of the tubes can be timed to take place every 12 hours.
