Title: Improvements relating to clutches for change speed gearing and the like
IPC: F16D23/08
Filed: 1933-03-10
Abstract: 416,090. Claw clutches. LINLEY, C., (Representative of LINLEY, C. M.), 357, Camden Road, Holloway, London. March 10, 1933, No. 7326. [Class 80 (ii).] In order to prevent engagement of a claw clutch except at synchronism, a ball (or roller) 11 is arranged between one dog member 5, provided with a pocket 12 on either side of which the ball is capable of limited arcuate movement, and a disc 13 which is in light frictional engagement, such as by oil drag, with the other dog member 8. The ball is controlled by abutments 7<c> and 13b on a reduced part 7<b> of the shaft 7 on which the member 5 is splined and on an axially-extending flange 13<a> of the disc 13, the pocket 12 being midway between the abutments 7<c> and lying over a spline, whereby on disengagement the spline ejects the ball from the pocket. Alternatively, the ring 13 may have a ball-retaining lip and be itself retained within the member 8, which latter may then be the movable member of the clutch, whereby the ball is withdrawn from the pocket on disengagement. During overrunning, the ball rolls against one or other of the abutments 7<c>, as shown in Fig. 3, and thus prevents engagement, the disc 13 then rotating in synchronism with the member 5 and slipping on the member 8. As soon as the relative direction of rotation is reversed, the ball rolls into register with the pocket and engagement can take place. Instead of or in addition to the abutments 13<b>, the disc 13 may have a radial projection engaging an arcuate slot in the shaft so as to limit its movement relative to the latter. As applied to preselective changespeed gearing, engagement is effected by means of a spring 15 interposed between the setting lever and a fork 14.

Filed: 1973-02-14
Abstract: 1365655 Winches HARNISCHFEGER CORP 14 Feb 1973 [24 Feb 1972] 7357/73 Heading B8B A crane winch comprises a drum 44 driven by a reversible hydraulic motor 34 which is interlinked with a spring operated hydraulically released brake 80, such that when winch lowering is normally selected the brake is first released followed by motor energization, when neutral is then selected the motor is de-energized followed by application of the brake and when winch hoisting is selected the motor is reversibly energized, lost motion linkage permitting the brake to remain applied, but a uni-directional clutch 74 allowing the brake to be over-ridden in this direction. The clutch 74 acts between the output shaft 36 of the motor 34 and a brake disc 72 engageable by discs 78 of the brake 80, which is controlled by a two position spool valve in circuit with the brake cylinder, a pump for the brake fluid and reservoir. The motor 34, which drives the drum 44 through shafts 36, 38 and planetary gearing 50, is controlled by a three position selector spool valve in circuit with the motor 34, a motor pump and reservoir. The degree of displacement of the motor spool valve varies the speed of the motor.

Title: Data transmission systems
IPC: H04B17/40
Filed: 1973-02-15
Abstract: 1401261 Radio frequency signalling; repeaters SIEMENS AG 15 Feb 1973 [14 April 1972 7576/73 Addition 1398961 Heading H4L Monitor signals, which may be selected ones of already-existing data signals such as the frame synchronizing signals in a t.d.m. system, are used additionally to indicate system faults if they are received incorrectly as in the parent Specification 1,398,961 butnow are only partially corrected before retransmission. In a t.d.m. format (Fig. 2, not shown) having 32 8-bit words per frame, and 15 frames per superframe, the first word of each frame is assigned the monitoring function, those of even frames being frame sync words RSW, and those of odd frames being message words MW carrying other channel information. The retention of uncorrected bits in the sync word RSW sent to successive repeaters serves to signal the occurrence of faults while maintaining sufficient correctness in the sync signal for it to perform its synchronizing functions. At each repeater (ZS1, ZS2, Fig. 3, not shown), connecting line sections between end stations (ESt1, ESt2), a circuit E, Fig. 6, recognizes the sync words RSW. If the sync words are correct, the rest of the words of each frame pass via line 1 to the output Fab by way of a circuit V. In this circuit V the bits 2, 3, 4 and 6, 7, 8 (but not bits 1, 5) of the sync word RSW are replaced by new bits from RG1, and bit 2 of the message words MW is replaced by a new bit from MG, this bit always being 1 to distinguish the message words MW from the sync words RSW whose second bits are always 0. For a wholly correct sync or message word the new bits are the same as the replaced bits and this process is merely a regeneration. If small errors occur in the received sync signals or message signals, circuit RGI, MG insert correct bits, as before, so that the next repeater is sent a sync word with at least bits 2, 3, 4 and 6, 7, 8 correct. If the error rate reaches a predetermined level, a circuit FRU operates a "non-urgent" alarm N and signals the fact via line T to the end station. If large errors occur, or even complete loss of received signal, an "urgent" alarm D is operated and signalled to the end stations; and the signal sent over Fab from V to the next repeater is derived from an auxiliary pulse generator HTG, instead of from the input signal, together with the sync word bits 2, 3, 4 and 6, 7, 8 from RG1. In this case the 5th bit of the sync word is derived from RG2 and is inverted relative to bit 5 of the last received sync word as an indication to the next repeater that "pseudoinformation" only is being sent from HTG. The end station can automatically act upon the urgent and non-urgent alarms to initiate automatic correcting procedures.

Title: Improved manufacture of sodium formate
IPC: C07C51/10
Filed: 1920-03-17
Abstract: Sodium formate is produced by introducing carbon monoxide into water containing sodium sulphate and lime, the sodium sulphate being maintained at a concentration not greater than 7 per cent calculated as Na2SO4.  This concentration may be regulated by the presence of basic sodium calcium sulphate, Na4Ca3(SO4)4 (OH)2, obtained by heating calcium or sodium hydroxide in water with sodium sulphate and calcium sulphate, or with substances containing or forming these compounds, e.g. calcium sodium sulphate, or sodium chloride and calcium sulphate.  Another method of maintaining the sodium sulphate concentration consists in adding sodium sulphate or calcium sodium sulphate or basic sodium calcium sulphate to replace the sulphate as it is consumed, excess of lime being either present in the reaction vessel or gradually added thereto. Specification 7875/04 is referred to.ALSO:Basic sodium calcium sulphate, Na4 Ca3 (SO4)4 (OH)23 is produced by heating calcium or sodium hydroxide in water with sodium sulphate and calcium sulphate, or with substances containing or forming these compounds, e.g. calcium sodium sulphate, or sodium chloride and calcium sulphate.

Title: Improvements in short-circuit induction motors
IPC: H02K17/30
Filed: 1930-03-11
Abstract: 345,084. Alternating-current motors. SWENDSEN, J. W., 9, Klingenberggaten, Oslo, Norway. March 11, 1930, No. 7945. Convention date, March 12, 1929. [Class 35.] ' In a short-circuited rotor induction motor in which the rotor is divided into two parts normally 180 electrical degrees displaced but arranged at starting to be gradually brought into line with each other, a longitudinally movable member is provided on the rotor shaft to control the relative displacement of the rotor elements. In Figs. 1 and 2, a strip-wound rotor element 5 is keyed to the shaft 4 and a strip-wound rotor element 6 is rotatably mounted thereon the two elements being normally pulled 180 electrical degrees out of alignment by a spiral spring 24 the movement being limited by a projection 26 on a friction clutch member 20 keyed to the shaft 4. When the motor is started the element 6 moves relative to the element 5 and in so doing acts by means of a camgroove 28 in a projection 27 attached thereto on a projection 29 on a plate 30 to move a piston 32 longitudinally in a cylinder 33 carried by the friction-clutch member 20 which is forced into engagement with a hub 11, carrying the loose rotor element 6. Thus the relative movement between the rotor elements is checked until the pressure in the cylinder 33 is relieved by the escape of fluid through a channel 34, when the friction clutch is released and the rotor element 6 can again move relative to the element 5. The checking action is repeated at intervals until the rotor element 6 is in line with the rotor element 5. Thus, although the motor starts as an induction motor having slipring characteristics with two independent secondary circuits, it runs as an ordinary short-circuited rotor machine. Slots are cut in the rings 18, 19 between the points of connection of the rotor bars 15, 16, so that a resistance is inserted at starting. The rotor bars of each element are connected to corresponding bars in the other elements by flexible conductors 17. In a modification the two rotor parts and the stator are of the usual cylindrical form and the clutch for arresting the relative movement of the rotor parts is actuated by a handlever. In a further modification the hub carrying the loose rotor elements is cut with internal threads engaging with a screwed bush slidably but not rotatably mounted on the motor shaft. In this case the bush is given an axial movement by hand through mechanical gearing, so that a rotary motion is imparted to the loose rotor element relative to the shaft. By regulating this movement it is possible to regulate the speed of the motor in the same way as an ordinary slip-ring induction motor is regulated.
