Patent GB-370633-A (GB)
Abstract: 370,633. Cash registers &c. KRUPP AKT.-GES., F., Essen, Germany. March 21, 1931, No. 8738. Convention date, June 12, 1930. Addition to 353,662. [Class 106 (i).] Adapted for multiple-item transactions.-The control of the various auxiliary functions of the machine is now vested in the clerk's keys, instead of in the amount keys as in the parent Specification and the initial controlling operation is performed by the machine drive and not directly by the setting operation. When a clerk's key 13, Fig. 1, is depressed it lowers a pitman 165 to place a lug 167 in the path of an arm 171 fixed to a shaft 69. In the subsequent operation of the machine therefore this shaft remains stationary and consequently the totaltaking stops are not placed in position and the link 83, Fig. 4, is not moved. If the item is a single one this results in operation of the link and therefore of the shaft 92 operating the various auxiliary devices. If on the other hand the multiple-item key 14 is also depressed the link 95 is displaced to the left so that no movement of the link 83 and shaft 92 takes place. To take a multiple-item total (the key 14 being down) the total lever is shifted and this through a cam 187 raises the pitman 165 to allow the shaft 69 to turn so that a total is taken, the auxiliary devices operated, and the clerk's and multiple-item keys released. If a total is required from a clerk's totalizer, the total lever is shifted as before and the clerk's key depressed. Consequently the shaft 69 is freed for operation by the cam 187, despite the depression of the clerk's key, and therefore the total-taking stop is rendered operative. No rotation of the shaft 92 occurs however as link 95 is not shifted and therefore link 83 is not reciprocated.

Abstract: 813,494. Compacting wet fibrous tubes. BROWN CO. Dec. 5, 1956 [Dec. 12, 1955], No. 37148/56. Class 87(2). A wet fibrous tube on an imperforate mandrel is pressed, to remove water, by placing it between three arcuate pressing members 36, 38, 40 having perforated surfaces, which members are held in a retracted position by springs 70, and then forcing the members against the pipe by supplying fluid to cylinders 24. The water from the pipe drains away through pipes 58, 60. A part 14 of the machine frame 10 may be pivotally mounted at 16 to facilitate the entry of the tube, and it may be locked in a closed position by a pin 20. To avoid the formation of marks on the pipe at the joint between the members, pieces of wire 80 may be soldered to the members. In a modification, Figs. 9 to 13 (not shown), the two upper pressing members are pivotally mounted, and each member is pressed against the pipe by an inflatable bladder.

Title: Variable band width intermediate frequency system
Inventor: DOELZ MELVIN L
IPC: H03G5/26
Filed: 1955-12-29
Abstract: 787,826. Variable selectivity apparatus. COLLINS RADIO CO. Dec. 29, 1955, No. 37299/55. Class 40 (5). In a variable band width amplifier an input signal is applied in turn to mixers 11, 17, 24, Fig. 1, separated by highly selective band-pass filters 16, 23, the mixers 11, 24 being fed with oscillations from oscillators 12, 19 while the mixer 17 receives oscillations from a difference mixer 18 receiving oscillations from the oscillators 12, 19. The maximum (or minimum) frequency passed by the circuit may be lowered (or raised) by decreasing (or increasing) the frequency of either oscillator and by both maximum and minimum may be effected by adjustment of both oscillators in opposite directions. The filters are preferably of the mechanical type as described in Specifications 722,645 and 722,664, [both in Group XL (b)]. Assuming the input signal has a frequency of 470 kc/s. and the oscillator 12 a frequency of 720 kc/s., then the output passes through the filter 16 having a centre frequency of 250 kc/s. and a band-width of 4 kc/s. Assuming the response of filter 16 to be according to curve A, Fig. 2, then adjustment of the oscillator 12 to a frequency of 719 kc/s. will displace the output from the mixer 11 to the form of curve B, Fig. 2, so that part of the response is lost. Due to the change in frequency of oscillator 12 the output of the difference mixer 18 rises to 206 kc/s., but since the signal received at mixer 17 is only 3 kc/s. wide it passes unaffected through filter 23 to mixer 24 where it is restored to the input frequency. By variation of the frequency of oscillator 19 the band-width of the system may also be varied, Fig. 3 (not shown). The mixers 11, 17 and 24 are preferably of the heptode type, Fig. 4 (not shown), energized from oscillators of the cathodecoupled type, Figs. 5 and 6 (not shown).

IPC: B21B1/04
Filed: 1961-10-18
Abstract: 934,741. Control of A.C. motors. LICENTIA PATENT - VERWALTUNGS - G.m.b.H. Oct. 18, 1961, No. 37392/61. Addition to 908,921. Class 38 (3). In the speed control arrangement for a multiunit rolling mill described in the parent Specification the storage device and comparator are replaced by differentiating and integrating devices 43 and 40. The current in armature 31 is measured by a current transformer 39 connected to the differentiator 43, whose output is thus proportional to the rate of change of the current. As shown, when the strip 5 reaches switch 6, 611 closes and the integrator 40 then operates and its output is used via amplifier 42 and field generator 38 to control the speed of the second stand until said output is reduced to zero, i.e. the total, algebraic, change in armature current is zero. A deliberate bias can be applied by a device 41. The contacts 611 may alternatively be closed when the sudden variation in armature current due to the strip 5 entering the second stand is detected, and the integrator may be disconnected at 7<SP>11</SP> either by switch 7, by a time delay switch, or automatically when the output of the integrator becomes a minimum. This output may also operate an indicator which shows the thrust or tension in the strip 5 between the stands.

Abstract: 1,008,868. Distillation of water. KUWAIT OIL CO. Ltd., and L. V. HELLIER. Sept. 27, 1963 [Oct. 4, 1962], No. 37627 /62. Heading B1B. [Also in Division F4] In a plant for the production of distilled water from salt water, the heater for the salt water comprises a tube 1, Fig. 3, which rotates on rollers 2 inside a stationary tube 7 with a clearance of about 1/ 16  inch between the tubes at the bottom. A gas-burner 3 is mounted inside one end of the inner tube and heat passes through the wall of this tube to the salt water which is fed through inlet 8 into the space between tubes 1 and 7. The steam formed in tube 7 passes through outlet 9 to a condenser. Tubes 1 and 7 are mounted within a jacket 10 so that the hot gases, which leave tube 1 through holes 6, pass back over tube 7 to stack 11. Scale is continually rubbed off the walls of tubes 1 and 7 owing to the small clearance between the tubes at the bottom. Blowdown with scale is discharged through outlet 12. The steam leaving the heater through outlet 9 is divided into two streams, and one stream is condensed in conduit 17, Fig. 4, which is provided with fins 18, by heat-exchange with gas flowing upwards through casing 13. The gas is injected through eight nozzles 16 against turbine wheel 14, which drives reducing-gear which in turn rotates the heatertube at about 20 r.p.m. The gas leaving the condenser through outlet 19 is burnt off away from the plant. The remainder of the steam is condensed in tube 24 in heat-exchange with salt water feed which is thereby heated to 150-155 ‹F, before it is introduced into the heater through inlet 8. An alternative form of condenser is shown in Figs. 9 and 10. In this condenser the steam passes through a pipe 33 in feed preheater tank 32 and then enters chamber 44 where it is condensed by sprays 36 of distilled water. The mixture of cooling water and condensate flows through pipe 37 into tank 38. Some of the distilled water is withdrawn as product through pipe 46, and the remainder is cooled in radiator 41 and then pumped to the spray 36. The rotary heater may be used to heat salt water which is then passed to a 20-stage flash evaporator wherein circulating distilled water is used as cooling- medium in the condenser tubes.
