IPC: B41J5/16
Filed: 1983-07-20
Abstract: A keyboard sub-assembly for a typewriter has a baseboard (1) formed with a plurality of upstanding projections (3) which receive keys (4) with a snap action. Each key (4) is a push-fit onto the correponding projection (3), and each key (4) is retained on the baseboard (1) by means of a lug (15) having a lip (17) which snap-engages within a recess (12) on the underside of the baseboard (1). A coil compression spring (18) is interposed between each key (4) and the corresponding projection tion (3). The sub-assembly of the baseboard (1) and the keys (4) can be assembled into a deck with a push-fit, as a result of the baseboard having projecting lugs (27) which snap-engage within slots formed in the deck. The keys (4) shroud the projections (3) so as to prevent foreign matter reaching the underside of the baseboard (1). <IMAGE>

Title: Rivets
Inventor: WRIGHT JOHN MICHAEL
IPC: F16B19/08
Filed: 1985-05-16
Abstract: A self-piercing rivet comprises a head (11) and a shank (3). The shank has a circular external profile and is formed with a hexagonal poke (4) whereby zones of weakness are formed at each apex of the hexagon.

Patent GB-2185135-A (GB)
Title: A pulse counter meter
Inventor: BERMINGHAM AUGUSTINE ANTHONY
IPC: G06M3/12
Filed: 1986-08-05
Abstract: A pulse counter meter for counting pulses of frequency and voltage within predetermined limits on telephone exchange lines (9 and 10) to determine the number of units used in a telephone call comprises a power circuit (14) which draws current from the exchange lines (9 and 10) to power a pulse monitoring circuit (12). A voltage is developed on capacitor C1 and zener diode ZD1 which charges the primary winding (16) of a transformer T1 through a transistor TR2 controlled by an oscillator IC1 and a flip-flop IC2. The secondary winding (17) of transformer T1 charges capacitors C4, C5 and C6,which store energy for the pulse monitoring circuit (12). The voltage of the pulses is detected by zener diodes ZD5 and ZD6 and transistors TR4 and TR3. The output from transistors TR4 and TR3 is fed through a low pass filter R20 and C9 to a pair of monostables 18 and 19. The monostable 18 is set to timeout in a time just less than the cycle time of the upper predetermined frequency limit, while the monostable 19 is set to time out in a time just greater than the cycle time of the lower predetermined frequency limit. Both monostables feed a counter circuit IC4, which in turn advances counter meters CR1 and CR2 through transistors TR5 and TR6. For pulses within the predetermined frequency limits monostable 18 provides counting pulses to counter circuit IC4 and monostable 19 prevents counter circuit IC4 resetting.   <IMAGE>

Probe height may be controlled by two piezo-electric crystals (13, 14) (Fig. 2) respectively responsive to lower and higher frequency signals. In (Fig. 3), current through hot wire (27) attached to hinged, turntable supporting, arm (25) effects movement of the arm relative to the probe, a feedback loop assuring control. <IMAGE>

Title: Offset printing
Inventor: RAUSING GAD
IPC: B41N1/00
Filed: 1986-12-16
Abstract: Cylinder provided with printing pattern for reproduction according to offset-printing comprising a layer (4) consisting of a lipophilic material which is coated on the outside with a very thin layer (5) of hydrophilic material. The hydrophilic material layer (5) is broken through within areas which correspond to the actual printing pattern so as to expose active ink transferring surface portions (6) of the underlying layer (4) serving as a printing medium within the said areas. Such a printing pattern is obtained preferably in that a cylinder surface consisting of lipophilic material is coated first with a very thin, wholly covering coating (5) of hydrophilic material, e.g. through vacuum precipitation, whereupon this coating (5) is removed within areas corresponding to the actual printing pattern, e.g. through burning off with the help of a computer-controlled laser beam, so as to expose corresponding active, inktransferring surface portions (6) of the underlying lipophilic cylinder layer (4) within the said areas. A cylinder having a thermoplastics lipophilic layer overlain by an evaporated film of aluminium is disclosed. <IMAGE>

IPC: G01N33/535
Filed: 1987-04-06
Abstract: An analyte is detected in an enzyme-linked assay, wherein the presence of a first enzyme is related to the amount of analyte. The first enzyme converts an inactive precursor of PQQ to PQQ or an active analogue thereof. The PQQ complements an apo-enzyme such as apo-GDH to form an active second enzyme (GDH). The second enzyme catalyses a reaction leading to a detectable signal. This signal is preferably measured bioelectrochemically such as by a GDH electrode as shown in Fig. 1. <IMAGE>
