Title: A disc brake actuator with slack adjustment
Inventor: ENDLER WOLFGANG
IPC: F16D65/56
Filed: 1985-11-22
Abstract: A disc brake actuator comprises a thrust member (23) which is adjustable in length to take up slack and which is constituted by an adjusting spindle (25) and an adjusting nut (24) engaging in each other through a non-reversible thread (26) and a rotatably supported actuating member (12), which transmits, via a device (16, 17) for the conversion of a rotary motion into an axial motion, an axial brake applying force to the nut of the thrust member in order to axially urge the latter against brake piston (2). When a predetermined brake clearance is exceeded a rotatable follower device (43) is engaged by the actuating member (12) through a lost-motion coupling (46, 47), and, via a unidirectionally acting coupling, in particular with a free-wheel coupling (52), transmits the rotation of the follower device (43) to the spindle (25) of the thrust member thus effecting adjustment to take up slack. In order to ease the resetting of the adjusting apparatus and to eliminate expansions of the calliper during the adjusting operation, a friction coupling (57) is arranged between the unidirectionally acting coupling (52) and the thrust member (23), said friction coupling transmitting torques up to a defined amount to the thrust member (23) and being ineffective instead beyond that amount of torque. <IMAGE>

Patent GB-2176070-A (GB)
Title: Digital to analogue converter
Inventor: REIBER HANS
IPC: H03M1/00
Filed: 1986-05-28
Abstract: A D/A converter is followed by a low-pass filter. To convert the digital signal values with a small amount of circuitry to an analogue signal that permits high-quality reproduction (e.g. stereo sound), the D/A converter is preceded by a coding circuit which transforms the digital signal values into pulse packets (22) each consisting of a number of pulses following each other without interruption. The repetition rate of these pulse packets is a multiple of the repetition rate of the signal values. The pulse packets (22) are largely symmetrical with respect to centerlines (ML) spaced at equal time intervals. A pulse on one and/or the other side of the centerline (ML) has an amplitude smaller than or equal to a maximum value, and all other pulses of the pulse packet (22) have the maximum value. The voltage-time area of each pulse packet (22) corresponds to the respective digital signal value. <IMAGE>

Title: Golf practice device
Inventor: WEIR JAMES KENNETH
IPC: A63B69/00
Filed: 1986-06-30
Abstract: A golf practice device comprises a reel assembly upon which a length of line 38 is wound, one end of the line being attached to a golf ball 44 such that the line 38 unwinds from the reel 18 when the golf ball 44 is struck. Means is provided for arresting the motion of the golf ball 44 as said line 38 approaches its maximum extension, and means is provided for rewinding the line upon the reel 18. Preferably the arresting means absorbs the momentum of said golf ball in a progressive manner. The other end of the line 38 may extend from the reel 18, and said arresting means may comprise a second reel 50, upon which the last few feet of the other end of the line 38 are wound. A bobbin 61 is mounted on a common rotatable spindle 52, the bobbin 61 having a second shorter length of line 60 wound thereon, one end of which is attached to a tension elastic 58 such that as the last few feet of said line 38 is unwound from the second reel 50, the bobbin 61 rotates, winding the second length of line 60 upon itself and so stretching the spring 58 and absorbing the momentum of the ball. The line 38 is rewound on reel 18 using an electric motor 66 which is axially slidable into and out of engagement with the reel axis. <IMAGE>

Title: Electromagnetically actuable fuel injection valve
Inventor: HANS WALDERMAR
IPC: F02M51/06
Filed: 1986-09-18
Abstract: An I.C. engine fuel injection valve comprises a nozzle body (9) with a valve needle (27), which is guided therein and has a shoulder (39) upstream of which is an abutment plate (12) having an opening (20) penetrated with radial play by the valve needle (27).

The wall of the opening (20) is interrupted by, apart from the passage (37), further recesses (42). Sticking between the abutment plate (12) and the needle shoulder (39), as can occur through adhesion forces and residual magnetic effects, is avoided through such a construction of the abutment plate. <IMAGE>

Title: Anchor nut
Inventor: ERLAM DAVID PAUL
IPC: F16B37/04
Filed: 1986-08-29
Abstract: A fastener (1) for use in securing a panel member to an apertured wall structure (5), is of resilient construction and comprises interengaging first and second parts (3, 4). The parts (3, 4) are formed so that by manipulation, the wall structure (5) is secured between portions of the parts (3, 4). (See Figure 4). The first part (3) of the fastener (1) comprises a bifurcated block having a head portion (3a) housing a screw-threaded insert which receives a fixing screw. The two jaw-like bifurcations (3b) of the first part (3) define an elongated hollow (12) which provides a lead-in for the fixing screw. The second part (4) of the fastener (1) comprises a flange portion (4a) defining a central hole (20), and four hooks or lugs (4b) disposed at the corners of an imaginary square. The hole (20) is sized to locate, with clearance, the fixing screw. To install the fastener (1) in the aperture (25), parts (3) and (4) are assembled whereby the lugs (4b) of part (4) are pushed or "snapped" over landings (18) of part (3). The interengaging assembly (3/4) is next pushed en bloc into the aperture (25) whereby the bifurcations (3b) of the part (3) initially collapse towards each other. The fastener (1) is firmly installed in place by pushing the part (3) away from the part (4) until the resilient bifurcations (3b) are free of the restraint provided by the aperture (25) and move apart, to "snap" into position wherby the lugs (4b) grip the bifurcations (3b), so that the flange portion (4a) and the end walls (18) are clamped securely together.

Patent GB-2232093-A (GB)
Title: Hydrocarbon vapour recovery.
Inventor: LUNT CHRISTOPHER JEROME
IPC: B01D53/14
Filed: 1989-05-17
Abstract: A method and unit for hydrocarbon vapour recovery from air contaminated with such vapour involves an adsorption phase in which the contaminated air is passed through a first adsorption bed (A) venting substantially pure air to atmosphere (34), and a subsequent regeneration phase in which recovered hydrocarbon is desorbed from said bed by vacuum extraction (84), the extract being passed to an absorber column (90) supplied with liquid absorbent (95) which absorbs hydrocarbon vapour extracted from said bed. The vapour from the head (99) of absorber is recycled through a second adsorption bed (B) during the adsorption phase of the process for that bed. The increase in weight of each adsorption bed during each adsorption phase is monitored by computer means. This enables the amount of hydrocarbon recovered to be measured, and in addition provides means of controlling the sequential operation of the adsorption phases to improve their efficiency. The supply can be cut and/or an alarm raised if any bed should approach saturation. Moreover, if one bed is not nearly saturated and regeneration of the other bed is completed, the vacuum pump can be turned off, saving energy.
Patent GB-2232238-A (GB)
Title: Damper control arrangement
Inventor: TAKAYAMA YUKIO
IPC: B60H1/34
Filed: 1989-05-25
Abstract: A damper control arrangement employs friction in providing resistance against the motion of a manually-operated disc 7. The disc 7 is complete with an actuator lever 3 for manual adjustment of the conditioning air flow. A friction plate 8 and the disc 7 are secured on a boss 21 mounted on the housing 1 by a screw 9. The outer edge 26 of the plate 8 is located in an annular recess 24. The elastic force exerted by the plate 8 upon tightening of the screw 9 forces the disc 7 against a spacer ring 28. This provides an inherent stiffness in the adjustment of the disc 7. <IMAGE>
