Title: Improvements in type wheel typewriters
IPC: F16D67/00
Filed: 1927-11-09
Abstract: 292,013. Mayer, P. OÀ Nov. 9, 1927. Index type-wheel machines. - A type-wheel and setting-devices therefor and an ink-supply roller are mounted on a lever which rocks on a vertical pivot and is moved horizontally towards the platen to effect impression; the lever may carry a feed-pawl which co-operates with a rack on the carriage to effect letter-spacing, and the typewheel may be associated with case-shift mechanism. In the machine shown in plan in Fig. 1. a lever 3 pivoted on a vertical pin 2 on the base 1 is provided with a pin 6 supporting a type-wheel 5, the lever being moved towards the platen 7 by means of a fingerpiece 4 to effect impression. Setting-mechanism for the type-wheel comprises a rack 18 mounted on the lever and gearing with a pinion 24 on the type-wheel. The rack is actuated by a knob 50 secured to a spring blade 20 pivoted to the rack, the knob being set with reference to an index plate 21 and having a ball 22 for engaging recesses 23 therein. Aligning for impression.-The pinion 24 on the type-wheel 5 co-operates with an aligning-tooth 43. Case-shift mechanism.-The type-wheel 5 has three rings of type and is raised to bring the middle or bottom ring to the printing line by depressing a key 34 which is pivoted on a lever 33 engaging the type-wheel. On depressing the key vertically, the bottom ring is brought to the printing line, but if the key is rocked before being depressed it is arrested by a stop 38 and the middle ring is brought to the printing line. Roller inking-arrangements.-An ink-roller 25 is mounted on a yielding part 30 of an arm 26 which is pivoted on a pin 27 on the base and has a lug 28 engaging a notched part, 29 of the lever 3. On moving the lever, the ink roller passes over the type-wheel and over an ink-supply roller 31 which is mounted on the lever. Letter-spacing mechanism.-A rack 9 on the carriage 8 co-operates with a pawl 11 consisting of a bell-crank which is slotted to engage a pin 10 on the lever 1 and is connected to returning- springs 12, 16. On moving the lever, the pawl engages the rack to effect letter-spacing, and then engages a stop 14 and moves idly on the pin during the further movement of the lever to effect impression. In some cases the pawl is merely pivoted on the pin and is arranged to yield on engaging the stop. The lever is normally arrested by a pin 40 on the base 1, but when it is necessary to effect spacing without impression a stop-sleeve 39 on the pin is depressed to arrest the lever before the type-wheel reaches the platen. Paper-shields.-For limiting the length of the typed line, the carriage 8 is provided with a coloured transparent shield 45 covering the end of the platen. The shield is mounted on a pivot 44 and can be raised to permit of typing in the margin.
Patent GB-315641-A (GB)
Title: Improvements in or relating to variable transmission gear and gear boxes
IPC: F16H29/08
Filed: 1928-10-18
Abstract: 315,641. Pritchard, H. C. Out. 18, 1928. Variable speed gearing with a quasi-ratchet action comprises oscillated slotted levers 6 with a transverse fulcrum bar 15 which is moved by levers 41 along the levers to vary the speed. A driving crankshaft 1 is connected by connecting-rod 3 to the levers 6 by pins 14 which slide in guides 5 in the casing 2. Links 9 are thus variably oscillated and these drive a shaft 11 in one direction through ratchet-toothed clutches 29 which are intermittently engaged and disengaged by cams 31 on the shaft 1 acting through rock-shafts 33 and forks 34. The one-way shaft 11 drives back to a tail shaft 23 in line with the driving-shaft 1 through a reversible countershaft 14. When a clutch 26 is put in to connect the aligned driving and driven shafts 1, 23 directly, catches 43 through levers 44 hold the rock mechanism 33 for the clutches 29 out of action. The shafts 14, 23 are geared constantly together by a pair 24, 25, and the shaft 11 is constantly connected by a pair 12, 13 to a sleeve 37 loose on the shaft 14. On the sleeve 37 is a bevel gear 17 constantly meshing with an idler 18. A splined clutch 40 and a splined gear 22 are adapted to be operated from a rod 39 so that the clutch 40 can be engaged with the sleeve 37 for forward driving, or the gear 22 with the idler 18 for reversed driving. Specification 275,886 is referred to.
Patent GB-365070-A (GB)
Title: An improved machine for looping tied strings into a chain of loops
IPC: A22B7/00
Filed: 1930-10-08
Abstract: 365,070. Knot-tying machines. RIDDLER, T., 30, Raymond Street, Timaru, New Zealand. Oct. 8, 1930, No. 30181. [Class 112.] Strings for tying up the legs of mutton carcasses are gathered into a chain of loops, for easy withdiawal without tangling, by a Knotter which loops each string into a loop formed by another string. The baseplate 1 has a knotter 2 of construction similar to those used in reaping and binding machines. The loopforming wheel 12 is housed in a casing 5 supported by members 3. A guide 4 has a slot 7 for a pivoted loop-holding lever 8 provided with a hook 10. The wheel 12 is rotated by a gear 13 nounted on a spindle 14 having a sprocket wheel 15 driven by a chain 16 from a wheel 17 on a horizontal spindle 18 rotated by bevel gears 19 from the spindle 20 of the knotter 2. A transverse spindle 24 has an arm 26 carrying a needle 27. A trip lever 29 on the spindle is retained in its rearward position by a spring 30 and has a quadrant 31 having a pin 32 engaging the lever 28. The string 60, Fig. 2, from a ball 61, passes through tension rollers 62 through an eye 63 on an arm 46 and then through ar. eye in the needle so that when the crank 37 is moved the needle is carried over to the position shown in Fig. 3, the end of the string being caught by the plates 65 and gripped in the usual way. The handle makes a complete rotation and the needle moves back to the position shown in Fig. 2. As the crank still rotates, the roller 47 of the needle arm 46 strikes the guide 51 and swings the needle on the opposite side of the loopforming frame 5, as shown by the dotted lines of Fig. 1, carrying the string into the mouth of 57 and down to the knotter plate 65 to the position shown in Fig. 3, the string entering the plates 65 in which it is again caught and held. As the needle reaches this position the spindle 20 of the knotter commences to rotate, the teeth 66 on the wheel 21 engaging the gear 23. The sprocket wheel 17 is thus rotated, turning the wheel 15 and causing the loopforming wheel 12 to rotate. Fig. 5 shows the wheel 12 in the same position as in Fig. 3, but with a loop 67 in the previously formed loop 68, and a loop 60 about to be formed in the loop 67. The loop 67 is held at the end 10 of the trip lever 8, passes below the loop 60 and is doubled back through the notch 53. The loop 67 is carried out of the notch 53 to the mouth of the wheel 12. The arm 28 then contacts with the tongue 32 of the lever 29 to release the loop 60. The string of loops is wound on a spool 70.

Patent GB-373924-A (GB)
Title: Improvements in alternating-current potentiometers
IPC: G01R1/28
Filed: 1931-11-02
Abstract: 373,924. Potentiometers ; current meters; frequency measurements. CAMPBELL, A., Culmora, Girton Road, Cambridge. Nov. 2, 1931, No. 30267. Addition to 342,441. [Class 37.] The potentiometer claimed in the parent Specification is modified to enable the phase splitter to be correctly set without knowledge of the frequency. The phase splitter shown in Fig. 1 corresponds with that shown in Fig. 6 of the parent Specification. The ratios of the resistance R and inductance L of the loop circuit that includes the secondary winding of the mutual inductance M to the corresponding values r, l of the loop circuit that contains the variable resistance s are made equal, so that R/r = L/l = c, where c is unity or other constant. The currents i1, i2 in these two loops are passed through the circuits of a differential ammeter, or two separate ammeters, and the resistance s, or the mutual inductance M, or both are adjusted until I1 = cI2' where i1, i2 are the R.M.S. values of the currents t1, i2. The currents i1, i2 are then in quadrature, and the frequency may be deduced from the observed values of the mutual inductance M and resistance s, or these may be calibrated to read the frequency directly. The differential ammeter shown comprises heaters #1, #2 acting on opposed thermopiles or thermojunctions in series with a galvanometer, the heaters being shunted if necessary. Alternatively the piles or junctions may be in opposing coils of a differential galvanometer, or the differential ammeter may consist of two circuits carrying the currents i1' i2 tending to deflect a ferromagnetic member or an eddy-current circuit such as a plate or closed loop. Mutual inductance between the two deflecting circuits may be compensated by external opposing coupling. The in-phase and quadrature components vb, va of the unknown voltage may be determined by including potentiometric resistances in the two loop circuits, or after the setting for frequency has been carried out the loop connected to the mutual inductance M may be open-circuited and the other loop made non-inductive without altering@ts resistance, the in-phase component being determined by potentiometric sliders and the quadrature component by varying the mutual inductance M. Standardization of the voltage v2, Fig. 3, in the third coupled circuit, i. e. the circuit of the coil D shown in the parent Specification, may be effected by means of a three-way switch which in its right-hand position removes the coil #2 from its loop circuit and connects it, through an adjustable resistance z3, across a shunt s3 in a direct current circuit carrying a standard current id. Tho resistance z3 is adjusted so that s3 + #2 + z3 = s and the current i is adjusted until the current in the coil #2 is the same for each position of the switch. The voltage v2 may then be calculated from the values of the mutual inductance M, the resistance s3, and the standard current id.

Filed: 1974-07-10
Abstract: 1443611 Underground storage SOC FRANCAISE DE STOCKAGE GEOLOGIQUE GEOSTOCK 10 July 1974 [10 July 1973] 30509/74 Heading E1F A heavy flowable substance which is solidified at normal storage temperatures, e.g. heavy fuel oil, is stored in a series of parallel underground galleries 2a, 2b .. 4a, 4b which open into a common central channel 5 and which have beds lying in the same horizontal plane, the substance being allowed to solidify; and is removed from storage by circulating a hot fluid over the surface of the substance so that the substance is progressively liquified and flows with the hot fluid towards the central channel 5 where it can be pumped out of storage. As described the substance is heated before being introduced into the galleries 2a.. 4b through the normally closed ends of the galleries via working gallery 6. The substance is then allowed to solidify. Fig. 2 shows the arrangement for removing solidified fuel oil from a gallery 14 having a basin 15 for collecting water. Line a-a represents the top 'surface of the solidified fuel oil and line b-b represents the oil-water interface. Steam is supplied along line 13 to heat exchangers 23 and 36. Heat exchanger 36 heats oil in a closed circuit including lines 38, 40, 42, pump 41. tank 37 and heat exchanger 39. The heat exchanger 39 liquifies the fuel oil in the region of pump 26 at the beginning of the removal operation to allow the pump 26 to remove oil along lines 27 and 11. Pump 16 then pumps water from the basin 15 along line 17, through heat exchanger 23 and along lines 24, 25 to the end 25a of the gallery 14. The hot water flows over the surface a-a of the solidified fuel oil to progressively liquify it and entrain it towards the pump 26 which pumps it out of storage. The hot water is removed from the liquified fuel oil by separator 2. In a modification the hot water is replaced by hot fuel oil which flows along lines 31, 33 and 25 to the end of the gallery 14.
