Title: Carriage drive for typewriter - has stepping motor drive and line start point registered by contacting stop with identification of location
Inventor: PFEIFFER ULRICH
IPC: G05D3/00
Filed: 1980-12-19
Abstract: The carriage drive for a typewriter includes a control circuit facility for providing positioning to a stop at the start of a line. The carriage of the typewriter (1) is moved by a continuous belt drive (2) that receives an input from a stepping motor (5). The motor receives pulses at a controlled rate from a microprocessor based control unit (9) over a drive stage. Identification of the end position is obtained by running the carriage against a stop. This results in an induced voltage being transmitted back to interrupt the drive pulses and to register the position for subsequent use.

Title: Method and device for controlling the chimney flue or the vacuum conditions in the burner space of a heating boiler
Inventor: RUDOLPH FRIEDRICH
IPC: F23N3/02
Filed: 1981-01-27
Abstract: The invention relates to an improvement to known smoke-gas flap regulators and their control. Smoke-gas flap regulators serve for reducing high waste-gas losses and therefore for increasing the efficiency of a heating system, an offtake of hot waste gases through the smoke-gas flue being prevented by closing the smoke-gas flap in the smoke-gas flue during the standstill time of the burner, and consequently the heat occurring during the afterglow of the lining of the burner space being utilised. Known smoke-gas flap regulators are controlled via solenoid valves or servo-motors, special thermostats and current-dependent switching and regulating devices being required, these being complicated to produce and being susceptible to faults during operation, for example in the event of a sudden power failure. In the smoke-gas flap regulator according to the present invention, a simple and reliable control of the chimney flue or pivoting of the smoke-gas flap takes place via a double-acting adjusting cylinder subjected to the pump pressure of the oil burner of the oil-fired heating system, the smoke-gas flap being pivoted into its opening position, during the standstill time of the pump and venting of the double-acting adjusting cylinder, by mechanical return means.

Patent DE-3204522-A1 (DE)
Inventor: BRAUN KARL
IPC: A61B17/10
Filed: 1982-02-10
Abstract: A stapler, particularly for suturing skin wounds or incisions, is disclosed which comprises a channel in which a driver is advanced by a slide in the direction of an anvil surface. A staple magazine which extends substantially parallel with the driver includes a curved section which opens into the channel to deliver staples into the channel for engagement by the driver. During forward displacement of the driver, a projection on the driver presses a leaf spring to which the anvil surface is connected. The anvil surface at the forward end of the leaf spring is thereby brought into its operating position and is automatically moved back into its retracted position upon release of the spring after the driver is retracted. The curved section in the staple magazine enables the stapler to have a slim profile which does not obscure the working area during a stapling operation. After completion of a stapling operation, the anvil surface is automatically retracted from a closed, implanted staple.

Inventor: WOLF FRANZ JOSEF
IPC: F16D13/68
Filed: 1982-03-26
Abstract: The rotationally elastic coupling makes possible the utilization of large twist angles between the two half couplings by converting the relative twist of the two half couplings into a radially directed translation by means of an eccentric link, a crank link or another appropriate movement-converting link which converts a rotational movement into a translation; the radially directed translation has an effect in the radial direction on sprung elastic intermediate links. The rotationally elastic coupling is particularly suitable for application in motor vehicle clutches and as a suppressor.

Title: Fliegende schere, insbesondere trommelschere
Inventor: DIEKMANN HEINZ-OTTO
IPC: B23D25/12
Filed: 1982-04-20
Abstract: Beim Schneiden mit Scheren dürfen Ober- und Untermesser nicht senkrecht übereinander stehen, um nach vollzogenem Trennschnitt nicht aufeinander zu stoßen. Die Schneidkanten der Messer (1, 2) werden daher mit Spiel (e) eingebaut. Während des Trennschnittes treten Kräfte senkrecht zur Schnittkraft auf, genannt Kaukräfte. Insbesondere bei Trommelscheren bewirken die Kaukräfte ein starkes Auseinanderdrücken der Messer (1, 2). Das kann soweit führen, daß das Schneidgut (3) nicht durchgeschnitten wird. Ein von Kaukräften kaum beeinflußbares Abscheren wird erreicht, indem der Drehmittelpunkt (Mo) des Messerträgers für das obere Scherenblatt (1) zum Drehmittelpunkt (Mu) des Messerträgers für das untere Scherenblatt (2) versetzt angeordnet ist. Die Drehmittelpunkte (Mo, Mu) liegen somit schräg übereinander, wodurch vor Schnittbeginn das Obermesser zum Untermesser ein Übermaß (-e) aufweist. Im Verlaufe des Schnittes verringert sich das Übermaß (-e) bis auf Null und nimmt erst mit dem Schnittende das erforderliche Spiel (e) ein.

Title: Synchroniser for shifting clutches
Inventor: MUELLER ERICH
IPC: F16D23/06
Filed: 1982-05-13
Abstract: In a synchroniser for shifting clutches, in particular of manual gearboxes for motor vehicles, which have a gear shift sleeve (9), a gearwheel (2) coaxial with the gear shift sleeve and having a clutch body (7) attached to it, and have a synchroniser ring (10) arranged between the gear shift sleeve and the clutch body, there is the risk that torques will be transmitted due to frictional forces between tapered surfaces (15, 16) on the clutch body (7) and on the synchroniser ring (10) even in the idle position of the gear shift sleeve and these may result in an unbraked vehicle being moved forwards. Such frictional forces can be avoided if the synchroniser ring is loaded by pressure elements arranged displaceably in bores of the clutch body with a force which acts in the axial direction and tends to separate the tapered surfaces (15, 16), so as to ensure that the gap between these tapered surfaces assumes the maximum possible value in the free-running position of the gear shift sleeve. As pressure elements it is possible, in particular, to use balls or pins which are either loaded by a spring or pressed against the front face of the adjacent synchroniser ring solely by centrifugal forces. <IMAGE>
Patent DE-3219519-A1 (DE)
Title: A direction-fixing element for castors
IPC: B60B33/02
Filed: 1982-05-25
Abstract: A direction-fixing element for castors has a stop plate which is fixed to a rotational bearing head which rotatably holds the wheel fork, on which plate a spring-loaded locking lever is movably mounted. This locking lever connects with an actuation lever and, when locked, detachably engages into a recess of the back of the wheel fork. In order to avoid operation of the actuation lever in opposite directions, the latter is displaceably guided on the stop plate between a locking position and a release position. At the same time, the actuation lever locks in the locking position with a locking nose on the flanged-on plate and can be tilted out of this locking position counter to the force of a restoring spring which then automatically moves the actuation lever back into the release position together with the locking lever.
