Title: Overload protection device for a handling device
IPC: B25J9/10
Filed: 1981-02-03
Abstract: An overload protection device for a handling device, comprises an arm 4, which is carried by and movable relative to a carrier 1 and carries a tool, a safety switch 22 provided between the carrier 1 and the arm 4 and included in the drive control circuit, a receptacle 2 carried by the carrier 1 and an element 3 which is carried by the arm 4 and is movable relative to the receptacle 2 and subjected to a yielding pressure force by springs 19, 20 and connected to the receptacle 2 by conical stops 17, 18 cooperating with counterstops in the form of conical openings 14, 15, 16 carried by the receptacle 2, which yielding pressure force determines a position which is limited by the stops 17, 18 and can be re-established by a movement of the stops 17, 18. The switch 22 de-energizes the drive in response to axial and angular relative movements between the receptacle 2 and the element 3. The element 3 is so mounted as to be also transversely movable relative to the receptacle 2. The springs 19, 20 may be replaced by magnetic coupling between the element 3 and the arm 4, while the conical stops 17, 18 may be replaced by subtantially hemispherical stops. <IMAGE>

Patent GB-2102998-A (GB)
Title: Portable alarm
Inventor: COOPER LEONARD CLAUDE
IPC: G08B13/14
Filed: 1981-04-10
Abstract: A portable alarm comprises a casing 11, 12 containing a powered audible-signal-producing means 18 powered by a replaceable battery 17. The battery 17 is coupled to the signal-producing means 18 via an "on/off" switch 21 which is resiliently biased "on" and which can be held "off", against the biasing action, only as along as pressure is applied to and maintained on a trigger 25. If the pressure is released, a part 26 of the trigger 25 flies out of contact with a spring-loaded plunger of the switch 21 and leaves the switch permanently "on". The trigger 25 is prevented from parting company altogether with the casing 11, 12 by a tail 28 which fastens the trigger 25 to the casing. Other embodiments are described, e.g. where the casing is deformable for operating the switch, and where the trigger can part company altogether with the casing. <IMAGE>

Title: Spectrometric gas analysis
Inventor: MAIDEN ADRIAN JOHN
IPC: G01N21/35
Filed: 1981-11-16
Abstract: Apparatus for determining the concentration of a gas, particularly a hydrocarbon gas, in the atmosphere employs a non-dispersive infra-red spectrometer priciple of transmitting a beam of infra-red radiation through the atmosphere and examining the signals produced as a result of its detection at a wavelength  lambda 1, at which the sought-for gas absorbs radiation, and at a wavelength  lambda 2 to which the gas is transparent. The detector 25 emits a pulsed beam containing the two wavelengths alternately in sequence from source means 27, 28 associated with the respective wavelengths. The radiation source in each source means is a gallium arsenide l.e.d. 29, 30 emitting at a shorter wavelength to excite a phosphor 32, which emits at the wavelength associated with that source means. A filter 33, 34 may be employed to limit radiation to a narrow band at the associated wavelength. By employing two electrically switched sources rugged and simple apparatus is possible. <IMAGE>

Title: Apparatus for ultrasonic imaging
IPC: G01S15/89
Filed: 1979-03-27
Abstract: In ultrasonic imaging apparatus comprising a portable scanning module including a liquid-filled enclosure (51) having a window (52) through which a beam of ultrasonic energy from a transducer (80) scans a subject, the beam to and from the transducer (80) is focussed by means of a lens (90) having a thickness defined by a surface of revolution around the axis of the beam. The lens preferably has an elliptical periphery which matches the shape of the transducer. Scanning may be effected by reciprocating a reflector (70), as shown, or by reciprocating the transducer (80) in the absence of a reflector, the transducer then being mounted at the end of the portable scanner. In another form, the reflector is omitted, the ultrasonic energy from the transducer passing directly through the window (Figure 6, not shown) with scanning being effected by oscillation of the transducer. <IMAGE>

Title: Photocopying machine
Inventor: GOEMANS HERMAN
IPC: G05B19/042
Filed: 1982-09-20
Abstract: In a photocopying machine, information is transferred between microprocessor controlled systems by means of a microprocessor input/output communication bus. One or more peripheral devices, such as automatic overlay, each including its hardware and an auxiliary microprocessor for controlling the auxiliary function is attached to the basic photocopying machine. The auxiliary cpu communicates with a central cpu in the basic machine by means of a parallel data bus. Noise in the system is substantially eliminated by transmitting messages in accordance with a strict protocol wherein each message contains a given number of bytes, a first instruction byte being provided for identification, a last byte being provided for checking (at least the first and last bytes having predetermined logic levels), intermediate bytes containing data and the start and finish of each byte being substantially synchronised with a given clock frequency. Noise is further reduced by voltage conversion of the messages transmitted to and received by each microprocessor. A predetermined waiting period after each transmitted message enables retransmission of a message if a receiving microprocessor is engaged.

The minimum dot diameter of the thickest ink of magenta and cyan MK and CK is larger than that of yellow, the matching points between the inks being indicated by L1-L5. Yellow ink having only one density may be used. 
<??>In a second embodiment which provides good skin colour reproductivity it is arranged that the minimum dot size which can be produced in cyan is smaller than that for magenta and yellow. In this embodiment (Fig 11) magenta, yellow and black inks of one concentration are used together with cyan inks of two kinds of dye concentration. For low OD values a dither matrix may be employed. Only one kind of cyan ink having a lower dye concentration than those of the yellow and magenta inks may be used, and the lowest drive voltages for the magenta and yellow inks may be set lower than that for cyan ink (Fig 16). The two embodiments may be combined (Fig 17). Electrophotographic or thermal printers may be used instead of ink jet printers.
