Title: Pressing iron
IPC: D06F75/22
Filed: 1963-11-25
Abstract: 984, 513. Steam and spray irons. SUNBEAM CORPORATION. Nov. 25,1963 [May 14,1963], No. 46461/63. Heading D1A. A steam and spray iron has a pump 39, Fig. 3, mounted with its inlet in a reservoir 21, a spray nozzle 65 which has means to impart fast rotary motion to the ejected spray, and a conduit 66 joining the pump and the nozzle. The iron has a handle 30 with a forwardly extending shelf 30f, and is attached to the iron by a U-shaped clamp 44, the bight 44a of which is screwed to shelf 30f and the ends of the legs are bent outwardly and grip under the edge of opening 40 in the top of the reservoir. The pump 39 comprises a cylinder 70, Fig. 4, having an inlet part 80 controlled by a valve 81 and surrounded by a screen 83, and a piston 74 operated by a rod 72 which has a button 85 at its upper end. The pump body is held down by a spring 84 between bight 44a and a sleeve 77 attached to cylinder 70. The piston is held up by a spring 87 between the shelf 30f and a collar 88 on stem 72. The spray nozzle 65 is mounted on a bracket 94 attached to bight 44a and is situated in the reservoir filling opening 42. Behind the nozzle opening 100 is mounted on hexagonal plug 102 the front face of which is grooved as shown in Fig. 7. Water which is forced forward by the pump finds its way between the flats of the hexagonal plug and the interior of the nozzle body and is forced along grooves 104 to annular groove 103. The water is thus ejected through the aperture 100 with a fast rotary motion. The iron also has conventional flash boiling mechanism and temperature control mechanism.

Abstract: 1378755 Testing high voltage lines for presence of voltage BRITISH RAILWAYS BOARD 5 Oct 1972 [7 Oct 1971] 46700/71 Heading G1U A high-voltage line (3) Fig. 1 (not shown) is tested for the presence of voltage by a rod-shaped unit (1, 4, 5, 6, 7) having a hook (2) at one end for contacting the line and including a dropper resistor (7A) and a transistorized detector circuit (7B), Fig. 2 which is arranged to energize a green lamp L 1 if the line is dead and a red lamp L2 if it is live. A fraction of the voltage on the line 3 is extracted by a potential divider RD, R1, R2, and coupled Cl to a switching emitter-follower VT1. If the voltage on the line is sufficiently high (e.g., above half the nominal line voltage) then the output from the emitter-follower is sufficient to switch a trigger VT2, VT3, so as to turn a transistor VT4 on and energize a relay RY having a change-over contact in the lamp circuit, relay chatter being avoided by a capacitor C2. The circuit may be tested by depressing a switch PB1 thereby simulating a live line condition. (For Figure see next page)

Abstract: 1480858 Data transmission; ciphering INTERNATIONAL BUSINESS MACHINES CORP 24 Nov 1975 [24 Feb 1975] 48153/75 Heading H4P In apparatus for ciphering blocks of data bits under the control of a set of cipher key bits, such a block, e.g. of 32 bits, is first stored, and the set of key bits linearly transformed to provide a permuted set of, for example, 48 bits. Predetermined ones of the stored data bits are then duplicated to provide an expanded block having bits equal in number to the number of permuted cipher bits. The bits in the expanded block are then combined with the permuted cipher bits, e.g. by modulo-2 addition, and the result is non-linearly transformed to provide a substitution set of bits equal in number to the number of bits, e.g. 32, in the original block of data. Finally, the substitution set is linearly transformed to produce a product block cipher of the stored block of data bits. Suitable circuit arrangement for effecting the ciphering process are described with reference to Figs. 1 to 8 (not shown).

Abstract: 1,094,216. Superconductor switched inductors. RADIO CORPORATION OF AMERICA. Nov. 30, 1964 [Dec. 6, 1963], No. 48570/64. Headings H1K and HIT. A switched inductor consists of a superconducting current-carrying conductor located close to a superconductor control plane. When the control plane is made resistive the magnetic field of the conductor expands from the restricted region it occupies when the control plane is superconductive. The inductance associated with the conductor thus increases. A sheet of ferromagnetic material may be placed below the control plane to increase the inductance in the high inductance state. The current-carrying conductor is so shaped that the return path of the image current induced in the superconducting control plane is short compared to the length of path over which current is induced. The magnetic field associated with the return path is thus confined to a small space so that the low state inductance of the device is kept to a minimum. The embodiment shown has a conductor of lead spaced from a control plane 31 of tin by a layer of silicon monoxide (not shown). An optional ground plane 32 of lead restricts the field emanating from the end portions 28, 30 of the conductor and prevents field spreading from the part of the return path on the underside of the control plane. Other constructions are described in which the shapes of the conductor, control plane, and ground plane are different. In all the embodiments described, the control plane is made resistive by passing a current through it, but it is suggested that a magnetic field, radiant energy, heat, or microwaves could be used in other devices.

Complementary clock inputs C, C are applied to respective inputs (transistors Q3, Q5) and the output S is fed back to one of the inputs of gate 11 (Q7). Operation.-Assume reset input R=logic 1 throughout i.e. Q6 is OFF, with C=logic 0, C = 1, Q3 conducts and Q4 is OFF. Thus inputs A and B have no effect.

If at least one of A and B are logic 0, at least one of Q1, Q2 will conduct, Q4 is OFF, S is 0 and Q7 is ON, Q8 is OFF. If A and B are both 1, Q4 is ON, S is 1 and Q7 is OFF. When clock C goes back to logic 0, C = 1 and the output state of S prior to this clock transition is retained. Applying a logic 1 to R at any time forces S to logic 0. A plurality of AND circuits similar to 10 may be used, the collectors of the respective reference transistors being connected to the common resistor R0. The batch may be used as a register element in a multi-bit register system (Fig. 2, not shown) to form master-slave units, masters (R1, R2) feeding slaves (R11, R12). Fixed width clock pulses are generated by suitable means (30) such as feeding a signal and a delayed inverted signal respectively into two inputs of a NAND gate (33). The delay and inversion may be obtained by feeding the signal via an odd number of inverter gates.
