Title: Improvements in and relating to the treatment of photosensitised layers
IPC: H01L21/312
Filed: 1965-08-05
Abstract: 1,072,994. Photo-sensitive materials and processes. PHILCO-FORD CORPORATION. Aug. 5, 1965 [Aug. 7, 1964], No.33561/65. Headings G2C and G2M. Photo-resists are produced by coating a support with a layer of photo-sensitized polyvinyl alcohol e.g. a dichromated layer, imagewise exposing the material to actinic radiation, washing the exposed material with water to remove the unexposed parts and then re-exposing the resist to such radiation which improves adhesion between the resist and the support. In the example, a layer of silicon is treated to form an oxide layer, coated with a solution of ammonium dichromate and polyvinyl alcohol, exposed to ultraviolet light through a mask, the unexposed areas washed off, re-exposed to ultraviolet light, baked to harden the resist, etched with HF to remove the silicon dioxide and treated with hot chromic acid to remove the resist leaving a material which may be used to manufacture capacitance diodes.

Abstract: 342,726. Intercommunication systems. POLLAK, J. E., 20, Holborn, London.- (Associated Telephone & Telegraph Co. ; 1033, West Van Buren Street, Chicago, U.S.A.) Nov. 5, 1929, No. 33674. [Class 40 (iv).] In an intercommunication system in which local conversations employ one common and one party wire, the speaking current is supplied from a local battery on local calls and from the exchange on external connections. Facilities for interim conversations with a third party are provided. The instrument, which is of the anti-sidetone type, has dialling facilities. To call a local station the push button PB is rotated to the position of the wanted party and is depressed to make contact with RB. The called party's buzzer B operates from A+, RB, individual line, B to -ve. When the called party removes his receiver this circuit is broken at SH, and the two transmitters are connected between leads - and C+ whilst the receivers are in series from - ve, over the individual line, to - ve. To make an exchange call the key TK1 (or TK2) is depressed, connecting the instrument to the exchange line, T1, T2, and operating visuals V1 at all local stations from battery across S1, S2. The speaking current is derived from the exchange battery. If an interim conversation with a local party is required the push button PB is rotated and depressed as before. This releases springs S of TK1 but springs H remain closed, holding the exchange and maintaining the visuals V1. The re-depression of TK1 re-connects the caller to the exchange line.

Title: Improvements in or relating to machines for making bottles or the like
IPC: C03B9/325
Filed: 1922-12-14
Abstract: 205,738. Wade, H., (Lockwood, L. V.). Dec. 14, 1922. Blowing.-In a machine for making bottles and the like comprising a series of moulds supported on a mould-carrier, a mandrel associated with each mould is secured against rotation while in elevated position. The tip-portion of the mandrel is slotted to receive lugforming members which can be projected and sheathed to form lugs or thread-segments within a bottle neck adapted to receive a stopper provided with threads or thread-segments. As shown in the Figures, the invention is shown applied to a machine having a series of invertible moulds. Each mould B<2> comprises a pair of main-mould sections 3 and a pair of ring-mould sections 3<a>, each pair meeting in a vertical plane and pivoted together on lugs 4<a> carried by a face-plate 1<a>. The sections 3 are connected by links 27 to a plunger passing through a trunnion which supports the face-plate 1<a>. A roller on the inner end of the plunger engages a cam on the centre column A<1> of the machine to open and close the moulds. A tubular member 5a carried by studs 6 and interlocking with the ring-sections 3<a> is provided with a sleeve 5, through which works a mandrel E, having a slotted head 8. Lug-forming levers 9 having recesses 9<b> and cams 9<a> at their upper and lower ends are pivoted at 10 in the slotted head 8. The cams 9<a> work in slots 15 in the mandrel shank 11, which is provided with a gudgeon 12 working in slots 13 in head 8. A spring 14 tends to press the head 8 away from the shank 11, so that on downward motion of the shank sufficient lost-motion is provided to withdraw the recesses 9<b> of the levers 9 from the glass in the ring mould before the mandrel is withdrawn. The mandrels are elevated at the glass-charging station S-1 by means of a device F which comprises a stem 19 having a T-slotted head 19<c> engaging a disc E<1> on the mandrel shank and raised by means of a pneumatic plunger 19<a>. Alternatively, a device F<1> having an inclined portion 29 up which the disc E rides on to the horizontal portion 29<a> may be employed. The mandrels are withdrawn by the cam device G carried by the machine-carriage A. At the bubble-blowing station S-2 the mandrels are held in their lowest position by means of the cam H while the blower I is pressed against the hollow shank 11 by means of the plunger 24. The cam H may be dispensed with and other means, such as the spring catches 16<a> may be employed to hold the mandrels in their elevated or depressed positions. The catches 16a engage vertical slots 18 and recesses 17. On leaving the station S-2, the mandrels are inverted by means of the gears 28 which engage a bevel rack. The moulds are opened and the blanks transferred to a blowing machine. The moulds may be retained in an upright position during their travel by means of a locking device or by frictional contact between the trunnions and bearings 2.

Title: Improvements in or relating to coil driven variable reactors
IPC: G01R17/06
Filed: 1956-11-29
Abstract: 842,604. Non-contact-making relays. UNILEVER Ltd. Nov. 29, 1956 [Dec. 2, 1955], No. 34542/55. Class 40 (9). [Also in Group XXXVI] A variable reactor (especially a capacitor) comprises at least one fixed and at least one rotatable member, the latter being free from control torque and driven by a coil and a magnetic field arranged for relative rotation, and clamping means comprising a part rotating with the rotatable member of the reactor, a non-rotatable part, and electromagnetic means for releasably clamping the two parts together. In Fig. 1 a moving- coil instrument, which is of standard form except that the lead-in wires 12 form such weak springs that they exert no control torque on the movement, has on its shaft 7 the earthed moving plate 14 of a variable capacitor. This plate and the fixed plate 15 are in the form of two diametrically opposed right-angled sectors. Rotation of the shaft is limited by stops (not shown) and the capacitance between the plates is a maximum when the shaft is midway between the two stops. The clamping mechanism comprises a flexible diaphragm 20 mounted on the shaft and co-operating with a coaxial fixed friction ring 23. When current is supplied to the terminals 26, 27 an electromagnet 25 is energized and clamps the diaphragm to the ring, preventing rotation of the shaft. The meter movement can be of the moving iron or ratiometer type. Circuitry (Fig. 2).-The reactor of Fig. 1 (28) is balanced against an unknown impedance 29 in an A.C. bridge of which the other arms comprise coupled windings 30, 31. When the impedances of 28 and 29 are equal the bridge is balanced and there is no residual flux in the core of the windings, but at other times a voltage is supplied to an amplifier 35 and compared with a reference signal in a phasesensitive detector 36. The error signal is passed through a servo loop 38 and fed to the coil of the variable reactor which is thus rotated until balance is obtained. The unbalance voltage can be taken from a secondary winding, and a Wien, Maxwell or Hay bridge may be used in place of that shown.

Abstract: 911,022. Writing telegraphs. COMPTOMETER CORPORATION. Oct. 10, 1960 [Oct. 15, 1959], No. 34625/60. Class 40 (1). In a writing telegraph the signal to control the engagement of the receiver stylus with the recording medium is generated by a switch mounted in the transmitter stylus support arm and operated whenever the transmitter stylus is moved into writing engagement with the recording medium. The stylus support member 15 comprises a channel-shaped plastic member attached to the arm 16 which is a part of the linkage system for generating the signals in response to the co-ordinate components of the movement of the stylus across the writing surface, and the switch is formed by contact 47 mounted on the support arm and contact 44 mounted on the ink conduit 36. The vertical compliance of the ink conduit is increased by flattening a portion 35 and also by breaking the conduit and inserting a flexible plastic sleeve 37 which also provides damping, electrical continuity across the plastic sleeve being maintained by wire 43. Spring 50, the position of which may be adjusted by screw 52, normally maintains the contacts open until the nib portion 38 is moved into marking contact with the recording medium. The stylus arm is manually actuated by a removable pen-like actuator, the end of which is shown at 17, which is attached to the stylus support arm via a ball-andsocket joint in which the ball is retained in the socket by permanent magnet attraction. A plunger 53 is also provided which may be operated by means not shown to move the pen into the marking position when the pen assembly is employed for receiver operation.
