Title: Study of luminescent materials by electron beam microscope - involves spectroscope with slit adjustable in height and width
IPC: G01J3/02
Filed: 1973-10-01
Abstract: Luminescent materials are studied by the observation of the light emitted when they are excited by an electron beam. A spectroscope is inserted between the sample and the photomultiplier tube and is operated to obtain optimum quality of image for the wavebands of interest. A sample (E) is set at an angle such that the telescope (10) receives the maximum energy from the source. A cylindrical light beam of reduced cross section is obtained at the output doublet (13). This beam is directed onto a dispersive glass prism (21) with minimum deviation for the sodium D radiation and then onto an achromatic condenser (31, 32). A slit (41) with adjustable level and opening selects the spectral region and intensity for the photomultiplier (PM).

Title: Knitting machine needle selector device includes flexible rods - selectively attracted from permanent magnet by electromagnet
IPC: D04B15/78
Filed: 1974-11-22
Abstract: A knitting machine (e.g. circular/flat bar) has a needle selector device comprising a flexible rod associated with pref. a needle jack of each needle, the rods being anchored at one end and being permanently attracted into a deformed position by a permanent magnet having a central pole piece. On the opposite sides of the rods is a group of electromagnets which are selectively excited to attract selected rods away from the permanent magnet to a position in which they can allow lifting of the associated needle. The arrangement reduces wear on the needle jacks and electromagnets and reduces fluctuations in the magnetic flux of the electromagnets.

Title: Wrist watch strap connection using strap resilience - has built in dowel projecting each side, with clearance to snap into frame
IPC: A44C5/14
Filed: 1975-04-23
Abstract: The connection to attach a wrist-watch strap to the watch body, uses the inherent elasticity of the strap to secure the attachment. The fittings are fixed to the strap and separate telescopic pins are not required. In one design the end of the strap (2) has a dowel (1) projecting from each flank, to engage sockets on the opposed internal faces of two cantilever arms. This dowel is longer than the distance between the cantilever arms (3), and can have a central section of increased dia. fixed in the strap. The remaining dowel lengths within the strap are housed in clearance holes. The connection is made by inserting one dowel in its socket. Continuing transverse pressure on the strap end then causes the strap to compress elastically and the dowel to gain further penetration, until sufficient clearance obtains to insert the other dowel. The strap then returns to its original size and the connection is secured.

Title: System controlling length of bar cut by continuous cutter - has regulator in cascade control chain and cutter move on which bar speed and buffer station depend
Inventor: SCHRODER NORBERT
IPC: B23D36/00
Filed: 1975-09-30
Abstract: The electromechanical mensuration control system is for use on a machine which continuously cuts e.g. bars (3) into specified equal lengths. The machine accepts a linearly displacing bar (3) into a similarly displaceable cutting (10) chariot (1). The system measures bar speed, sets up compatible chariot motion, and uses signals from a chariot mounted buffer (9) to synchronise the two displacements whence the cut is authorized. The bar speed may be measured by a tachometer (11), the speed value transmitted to control, and the chariot displaced in accordance with the relationship between the buffer (9) and its datum. The bar encounters the buffer which is displaced and further corrective chariot motion effected.

Title: Automatic machine for mounting small parts on metal wire - to avoid hand jigging prior to electroplating the parts
IPC: C25D17/28
Filed: 1975-12-09
Abstract: The workpieces, e.g. washers, are stacked in a magazine from which a reciprocating feeder pushes the washers one after the other on to a table to a work station, and metal wire flows freely from a spool over the washer. A reciprocating plunger drives a loop of the wire through the hole in the washer. A slide then bends the vertical loop of wire so it is horizontal and aligned at 90 degrees to the direction of travel of the washers, and the end of the loop is bent upwards and over the periphery of the washer by another forming tool. The result is that a row of washers is securely clamped on one length of wire. The wire on which the workpieces are clamped is mounted on a frame for electroplating, e.g. with Cr, where the wire forms the cathode connection. Method eliminates expensive manual labour involved in mounting small parts by hand on conductor wires prior to electroplating. Such parts can be barrel plated which is inexpensive, but the coatings obtd. are of mediocre quality. The invention permits parts to be vat plated without expensive hand jigging.
