Title: Improvements in and relating to change-speed planetary gearing
IPC: F16H3/66
Filed: 1936-12-24
Abstract: 475,843. Change speed planetary gearing. FLEISCHEL, G. Dec. 24, 1936, No. 35391. Convention date. Dec. 26, 1935. [Class 80 (ii)] Change-speed gearing comprises a main planetary train controlled by one or more other three-element planetary trains. In the arrangement of Fig. 1, of a main three-element train 2, 3, 6, the sun gear 2 is fast on a driving-shaft 1, the planet-carrier 3 is fast on a driven shaft 5 and the element 6 is permanently connected to a first element, the carrier 7, of a controlling train, the other two elements 9, 10 of which are each adapted to be alternatively clutched to a rotating part and braked. Thus, when springs 13 are allowed to expand freely, a clutch cone 11a rigid with the sun 9 is engaged with a clutch cone 14a fast on the driving-shaft 1 and a clutch cone 11b rigid with the annulus 10 is engaged with a cone 14b rigid with the driven shaft 5. An overall solid drive results. When a braking cone 20a is advanced alone to disengage the clutch 11a, 14a and to hold a cone 12a, a reduced drive results. When a braking cone 20b is advanced alone, another reduced drive results. When the cones 20a, 20b are advanced together, there is a double reduction. These braking cones are operated by opening valves 18, 48 alternatively to pumped oil. An arrangement is described with a reversing train in front of the gearing shown in Fig. 1. An arrangement is indicated in Fig. 7 (not shown) in which a second element such as 10 of a first controlling train is permanently connected to a first clement of a second controlling train like the train 9, 7, 10 of Fig. 1. This yields eight speeds. An arrangement yielding sixteen speeds is indicated in Fig. 8 (not shown), in which in addition to the second element 10 of the controlling train of Fig. 1 being connected to a second controlling train, the third element 9 of that train is also similarly permanently connected to a first element of a third controlling train, the other two elements of which are adapted to be clutched and braked alternatively. In a seven speed arrangement shown in.Fig. 6, the main planetary gear has triple planets supported on a carrier 74 fast on a driving-shaft 51 and meshing with a sun 70 fast on a driven shaft 55 and meshing also with two reaction suns 52, 53 which are adapted to be connected alternatively by a shift clutch 66 with a first element 54 of a controlling train. The two other elements 56, 57 of the controlling train carry armature discs 84, 85 which can be clutched at 87 and 92 respectively and braked at 62 and 63 respectively.

Patent GB-1281885-A (GB)
Title: Digital information storage devices
Inventor: ASPINALL DAVID
IPC: H01L27/07
Filed: 1968-07-26
Abstract: 1281885 Transistor bi-stable circuits D ASPINALL D J KINNIMENT and D B G EDWARDS 25 Sept 1969 [26 July 1968] 35931/68 Heading H3T [Also in Division G4] An integrated circuit associative store comprises a matrix of single-bit storage cells, each formed as a bi-stable circuit having two doubleemitter transistors. One emitter of both transistors in a cell is connected to a word line common to all the cells in a row. The other emitters are connected to respective digit lines common to all the cells in a column. When the store is to be interrogated each bit of the interrogate word is applied to one or the other, dependent on the bit state, of the lines of the respective digit line pair, the resultant change, if any, in the word lines being detected by means not described. In one embodiment, Fig. 1, the bi-stable storage cell shown is interrogated by raising the potential of digit line Da or Db above that of the word line. If, for example, T1 is conducting, raising Da will cause the current in T1 to flow to the word line, but raising Db will cause no current flow. To write a bit in to the cell the potential of the word line and of one or other digit line is raised. The transistor connected to the digit line at the lower potential will then be forced to conduct. To increase the temperature operating range and to reduce the possibility of destroying the stored bit during interrogation the collectors and bases are cross-coupled by diodes (D1, D2), and the bases are connected to earth via resistors, Fig. 2 (not shown). To reduce current leakage from each cell to the word line the forward collector-base current is reduced by a diode and a resistor connected in series between the collector and base of each transistor, so preventing saturation, Fig. 3 (not shown). To counteract the effect of a voltage supply drop in line 1 the circuit is modified as shown in Fig. 4, T3, T4 replacing the diodes (D1, D2) referred to above. The integrated circuit form of Fig. 4 is described with reference to Fig. 5 (not shown).

Abstract: 368,329. Driving magnetos. SCINTILLA AKT.-GES., Solothurn, Switzerland. Nov. 29, 1930, No. 36060. Convention date, March 10. [Class 35.] A trip-mechanism for a magneto consists of a driving part F and a driven part G connected by a spiral spring H and enclosed in a casing A. Within the casing A are a fixed segment M and an adjustable segment M<1> provided with serrations whereby they can engage with a serrated plate C attached to the magnate casing. Pawls J, K on the part G engage with the edges of the segments M, M<1> until disengaged by cams L on the part F. The timing is regulated by adjusting the casing A with respect to the plate C, and the speed of rotation at which the trip mechanism acts by adjusting the segment M<1> to alter the width of the gap O between the segments M, M<1> at the upper side of the device. The pawls J, K are so weighted that when the motor has speeded up they are kept by centrifugal force from engaging the segments M, M<1>.

Title: Improvements in balancing apparatus for roller shutters and doors
IPC: E06B9/62
Filed: 1934-12-17
Abstract: 441,233. Balancing-apparatus. DECAT, J., and DECAT, L., 60, Place Jules Ferry, Montrouge, Seine, France. Dec. 17, 1934, No. 36122. Convention date, Dec. 21, 1933. [Class 78 (ii)] [See also Group X] Balancing-apparatus for a roller shutter c comprises a chain of counterweights m, one end of which is attached to a cable d wound on a drum a in the reverse direction to that in which the shutter is wound on its roller, and the other end of which is connected to a bracket g fixed to a wall or pillar at a sufficient height above the floor to prevent contact therewith of any member of the chain as the cable d unwinds from the drum a. The counterweights m are preferably made up of plates p, any number of which can be threaded on bolts, but may consist of pivoted receptacles adapted to contain variable amounts of heavy material. Instead of using counterweights as above spaced apart at equal distances, counterweights of uniform weight may be used, and the desired result produced by varying the distances between them. When rapid and automatic closing of the shutter is required, the counterweight is arranged to exert a smaller turning moment than the shutter in all positions, and is held by a releasable arrangement. The first and last members of the chain of counterweights may be made lighter and heavier than normal to facilitate the starting and braking of the shutter. The apparatus is stated to be applicable to bascules and trap doors. The Specification as open to inspection under Sect. 91 comprises also a spring catch for engaging automatically with the last element of the counterweight, which is released by hand, by a fusible element, or by a thermostat. This subject-matter does not appear in the Specification as accepted.

[Also in Division F2] A typewriter is provided with a clutch for the carriage return or case-shift mechanism and the clutch comprises a disc 1, Fig. 5, which is integral with a cam 2 and made of a plastics material, the free face of the disc 1 being provided with a pawl 5, Fig. 1, so that when the latter is released its projection 5a, with the clutch mounted on a continuously rotating snatch roll 11, rocks into engagement with the teeth on the snatch roll to rotate therewith through one revolution. One revolution of the clutch causes the cam 2 to rock a lever 16 of the carriage return or case-shift mechanism. The pawl 5 is released on depression of a carriage return or case-shift key 14 whereby a lever 15 is rotated clockwise and its associated lug 15a is lifted upwardly to release the pawl, which is arrested after one revolution by the lug 15a if the key 14 has been released or by a lug 13a on a key lever 13 if the key 14 is still held in the depressed condition. The pawl 5 is guided by lugs 9, 10 and co-operates with a locking pawl 6, Fig. 5, mounted on a pin 4 and interconnected with the pawl 5 by a spring 7, Fig. 1, to prevent reverse rotation of the clutch. The locking pawl also determines the initial position of the clutch.
