Abstract: The printer has a thermal printing head 20 which is interchangeable with an ink-jet printing head. Each of the heads can be mounted on a carriage on the printer and has terminals 23a for engagement with terminals on the carriage. The head 20 has an arm 27 which is detected by a photo-sensor on the carriage to identify the presence of a thermal printing head. The ink-jet printing head does not have such an arm. The photo-sensor determines the appropriate set of pulse currents to be supplied by the electronic circuit of the printer through the terminals 23a to operate the printing head which is in use. Alternatively the nature of the printing head which is in use can be sensed electronically in dependence on the resistance of the resistors in the two heads.

Abstract: A hand-controlled mechanism is described for producing signals to move the position of a cursor in a computer display. The mechanism includes a shaft (12) with an elongated axis and a cylindrical member (10) mounted coaxially around a portion of the shaft (12), the member being both rotatable about and slidable along the elongated axis. The cylindrical member (10), has sets of encoding markings (18,20) directly emplaced thereof, which markings are parallel to and transverse to the elongated axis of the shaft (12). Optical sensing devices (60,62,64,66) are provided and are responsive to the movement of the sets of encoding markings to provide signals indicating both rotational and axial movement of the cylindrical member. Decoder circuits (92) are responsive to those signals to produce additional outputs which may be used to move the position of the display cursor.

Abstract: A fuel injection device of an engine for a vehicle having a power transmitting system connected between the engine and the drive wheel. The relative angle of torsion between the opposed ends of the power transmitting system is maintained at the converging angle of torsion determined by a required amount of fuel when a cruising operation of the engine is carried out. When the required amount of fuel is changed from a first required amount of fuel to a second required amount of fuel, a pre-injection is carried out prior to the main injection. The amount of fuel and the injection time of the pre-injection and the start time of the main injection are determined so that the relative angle of torsion becomes equal to the converging angle of torsion determined by the second required amount of fuel when the main injection is started, and that the relative angle of torsion is maintained at the converging angle of torsion determined by the second required amount of fuel after the main injection is started.

Abstract: A pneumatically operated hand-held wire stripping tool having a first housing for supporting operating elements of the tool and a second housing for substantially containing pneumatic elements of the tool is constructed such that the first housing is rotatably coupled to the second housing for rotation into either a left hand or right hand operating position. The operating elements of the tool include a first pair of opposed clamping jaws and a second pair of opposed cutting blades. The jaws and blades are coupled such that initial actuation of the tool closes the jaws and blades and continued actuation displaces the jaws with respect to the blades. The pneumatic elements comprise a pneumatic valve and a diaphragm supported on a stem with the stem extending through the diaphragm and into engagement with one of the operating elements of the tool. An aperture extends coaxially with and substantially through the stem and terminates adjacent the operating element. A viaduct extends from the valve and into the aperture for providing air communication between the valve and aperture. An opening in the stem passes through the aperture for communicating air to one side of the diaphragm.

Abstract: Disk storage apparatus comprises driving means (78) responsive to a drive signal for moving a head radially across any storage disk compatible with the apparatus. The velocity of the head moving across the disk is detected by velocity detecting means (74). A target velocity of the head is indicated by a velocity profile stored in a memory (86). Control means (200) measures the time required for moving the head by a predetermined distance at a predetermined velocity. A drive signal generator (90) generates the drive signal as function of the difference between the target velocity and the output from the velocity detecting means and the difference between the measured time and a predetermined value. This advantageously permits the velocity of the head during a seek operation to be controlled independently of scatter in circuit constants or variations in disk structure, and allows successful transition between seek operation and track following operations.

Abstract: A pipeline connection arrangement, consisting especially of plastic, contains a first pipe (2) or moulded part which has a collar (4) with a bead (10), and a second pipe (14) or moulded part whose tip end can be pushed into the collar (4). Arranged in the bead (10) is a sealing element (20) whose sealing lip (26) rests in a sealing manner on the tip end and to which an annular apron (22) is connected. This connection arrangement is intended to be constructed to the effect that, with a low production and material cost, the transition between different pipe systems is sealed in a functionally-reliable manner. It is proposed that, for use in the transition region of two different pipe systems which have a different internal diameter and/or wall thicknesses, the external diameters of the sealing element and of the apron (22) be matched to the first pipe system, and the internal diameter of the sealing element (20) and of the apron (22) be matched to the second pipe system. <IMAGE>

Abstract: A depilation apparatus having a number of disc-shaped pinching plates (19) provided on a drive shaft (7) and a number of thrust cogs (41) provided on an auxiliary shaft (21), by means of which cogs the pinching plates are each tiltable about a first and a second tilting axis (81, 91) from a catching position into a pinching position in which the relevant pinching plate (19) exerts a pinching force on an adjacent pinching plate (19) tilted into the pinching position. Each pair of pinching plates positioned next to one another (19a, 19b), (19b, 19c), (19c, 19a) has a unique thrust cog (41a, 41b, 41c), so that each pinching plate (19) is in cooperation with each of its two adjacent pinching plates (19) and the hair catching range of the pinching plates (19) extends over the entire depilation opening (3). The thrust cogs (41a, 41b, 41c) are provided on the auxiliary shaft (21) at mutual angles of 120°, so that an even operation of the depilation apparatus in time is achieved and an undesirable contact between the pinching plates (19) at a side of the drive shaft (7) remote from the depilation opening (3) is prevented. The pinching plates (19) each have a central, star- shaped opening (65, 67, 69, 71) by means of which the relevant pinching plate (19) is mounted in recesses (59, 61, 63) of three comb-shaped support ridges (51, 53, 55) of the drive shaft (7), which ridges extend parallel to a central portion (57) of the drive shaft (7) at mutual angles of 120°. A favourable moment arm ratio for the pinching force and a stable support of the pinching plates (19) in the pinching position are achieved by this.
