Title: Sound insulating floors
IPC: E04B9/00
Filed: 1979-04-10
Abstract: In a floor structure suitable for multi-storey buildings and moderate spans and of the kind comprising, in addition to a statically load-supporting component composed of a number of prefabricated floor slabs e.g. (20) supported in side by side relationship, a ceiling (22) supported at a distance below the load- supporting component, there is achieved, a very good impact noise insulation by giving the floor slabs (20) a weight per surface unit below 150 kilogrammes per square metre and at the same time such a design that they neither in their entirety nor in any portion have a natural frequency falling within the frequency range between 50 and 600 Hz. A soft floor covering 21 is preferably employed on top of the structural floor, which may comprise a double-ribbed structure formed from a cast cementitious material. <IMAGE>

Title: Vehicle headlamp
IPC: F21V7/00
Filed: 1979-05-11
Abstract: A vehicle headlamp for producing a Z-beam pattern has a reflector defined by rotating an ellipse about an axis which passes through the inner focus of the ellipse and is inclined at an acute angle (1-2 DEG ) to the focal axis of the ellipse. A bulb having a shielded filament for producing an inclined cut-off (Figure 6) is orientated in the opposite sense to that in which it is orientated in a conventional headlamp. Lensing portions at the front of the reflector split the basic beam immediately below a horizontal portion 7 of the cutoff line into parts 51a and 51b which define upper and lower, mutually laterally displaced horizontal cutoff portions 60 and 62 (Figure 7) in the required Z-beam. One lensing portion also utilises a part-circular cut- off portion of the basic beam to define an inclined portion of the Z-beam and further lensing portions depress and/or laterally shift other portions of the basic beam to reinforce other portions of the Z-beam. <IMAGE>
Patent GB-2021835-A (GB)
Title: Making and examining security documents
IPC: G07F7/08
Filed: 1979-05-21
Abstract: This invention relates to the recovery of data from the security features of a security document. By reference to the position of a coded "sentinel" within the data message the bits chosen to represent the data may be retrieved. By erasably recording the position of the "sentinel" on the document at personalisation, false recovery of the data is avoided. A cash dispenser credit card has a security element in the form of a magnetic tape bonded to the card. The tape before application to the card has a permanent magnetic structure arranged to form code or identity numbers sandwiched between sentinel codes. A length PR of the tape is bonded to the card. The length may contain only one sentinel code. Additional information is recorded on the card in a portion of the card containing erasable data, to indicate the position of the sentinel. <IMAGE>

Title: Gate valve
IPC: F16K3/18
Filed: 1980-03-07
Abstract: A gate valve comprises two spaced plates (18, 20) which move together from an open to a closed position in which a peripheral portion of each is received in a recess defined by walls (14) surrounding inlet and outlet ports and a bridge member (16). Means (21, 22) are provided for forcing the plates apart when the plates (18, 20) are in the closed position to compress a seal (28) between each plate (18, 20) and a recess wall (14). This forcing means comprises links (22) coupling each plate (18, 20) to a common shaft (21) which also serves to open and close the damper. A further pair of links (24) is mounted on a common pivot (26) and abuts the bridge member (116) in the closed position of the valve so that continued movement of the shaft (21) rotates the links (24) to urge the plates apart. <IMAGE>

Title: Rear view mirror assembly
IPC: B60R1/064
Filed: 1980-05-02
Abstract: A rear view mirror assembly has a head 10 mounted on a base member 54 by means of two arms 14 and 16. The arm 14 is coupled by a universal joint to a knob 68 and has a screw-threaded portion 32 which engages in a nut 30 on the mirror head 10. Thus rotation of the knob 68 moves the mirror head 10 about a vertical axis. The base member 54 is rotatably mounted on the shaft 48 and held stationary by friction pads 56. If the knob 68 is pressed to the left (as viewed in the drawing) it engages, via friction pads 72, with the end of a stem 44 on which the base member 54 is mounted. Further depression of the knob 68 disengages the friction pads 56 so that rotation of the knob 68 then causes rotation of the base member 54 to move the mirror head 10 about a horizontal axis. <IMAGE>

Title: Method for chemical nickelling of metal parts
IPC: C23C18/34
Filed: 1980-05-16
Abstract: In the electroless deposition of nickel, three concentrated solutions are used, the first containing a nickel salt and an accelerator, the second a reducing agent, a complexing agent, stabiliser and a wetting agent, and the third the same reducing agent as the second solution, a complexing agent and a stabiliser. The work solution is prepared by mixing the said first and second concentrated solutions together with water in a predetermined ratio to give a bath of predetermined chemical composition suitable for effecting chemical nickelling; and the composition of the work solution is regulated in the course of the chemical nickelling by direct addition of equal volumes of the said first and the third solutions, the volumes used being chosen as a function of the area loading of the work solution. The temperature of the work solution is preferably increased linearly in the course of the nickelling, starting from the optimal work temperature and reaching a temperature of 2 DEG C lower than the boiling temperature of the work solution.

Title: Electromagnetic noncontacting measuring apparatus
IPC: G01R27/06
Filed: 1980-07-23
Abstract: To follow the changes in impedance of a substance (68) located within a specified investigation zone (56), a bidirectionally focused electromagnetic beam having a pair of foci (12a, 12b) is aimed with one of its foci located adjacent such a zone. A receiver (14) located adjacent the other one of its foci is monitored for electrical changes therein, and such changes are interpreted as indications of impedance changes in the selected zone (56). Microwave energy is radiated by a ring aerial 23 and focussed by a polystyrene lens 12 having director rings parallel to the aerial ring on its inner surface (not shown). The microwave signal is applied across diametrically opposite points of the aerial 23 and picked up similarly by the tubular detector 14. The apparatus is pivotally suspended for ease of poisitioning to monitor the impedance of the wall of the human heart or to detect flaws in metal. <IMAGE>
