Title: Improvements in electric irons
IPC: D06F75/26
Filed: 1921-09-08
Abstract: 189,573. Denny, C. W. Sept. 8, 1921. Retractive switches; switches, quick-break; handles; springs, arrangement and disposition of. -Retractive switches for electrically heated irons &c. are provided with a latching arrangement in conjunction with a pivoted spring-pressed contact blade, so arranged that a comparatively weak spring pressure on the operating handle has to be overcome while gripping the handle, the stronger spring producing a quick break on the switch blade being brought into action only when the operating handle is sufficiently released, the circuit being broken simultaneously at four points in series. The blade B pivoted at b with retractive spring E has a nose B<3> which is engaged by a spring-pressed sliding catch D when the operating lever C is depressed. The handle C is pivoted at c and has a comparatively weak retractive spring F. As the handle is released, a cam surface C' engages ears on the catch D, releasing the blade B which is moved with a quick action by the spring E to break the circuit. The switch contacts comprise pairs of fixed V-contacts A<1>, A<3>, A<3>, A<2>, bridged by insulated plates B<1>, B<2>, carried by the switch blade. The pair of contacts A<3> are integral or electrically connected together, leads J, J' being connected to the outer pair A<1>, A<2> so that the circuit is broken at four points in series. To make these breaks simultaneously the fixed contacts are suitably stepped or bevelled. The operating-lever C is shaped to conform with the handle G when the switch is in the closed position, Fig. 2, the switch parts being arranged within a recess in the handle.

Title: Improvements in or relating to calculating apparatus for multiplying
IPC: G06F7/44
Filed: 1945-09-24
Abstract: 599,767. Statistical apparatus calculating-apparatus. BRITISH TABULATING MACHINE CO., Ltd., and BAILLIE, G. H. Sept. 24, 1945, No. 24694. [Class 106 (i)] Apparatus for multiplying two factors, each of a plurality of denominations, of which at least one comprises a non-decimal denomination, has product relays in a four-figure system for each denomination of one factor with all denominations of the other factor and has the contacts of the product relays connected in addition chains, and is characterised by means for selecting, for each denomination, a single one of the addition chains so as to give a result of digits in this denomination, for operating the indicating or recording device which represents digits in this denomination, and means for transferring to the selected addition chain those parts of the results from the other addition chains which contain digits in this denomination. In one embodiment, two digits of a decimal multiplier are sensed in a record card by brushes 10, 11, Fig. 2, co-operating with a roller 8 connected by a brush 9 to a supply line 3a and operating in known manner. An emitter 13, operating in synchronism with the feeding movement of the card, connects a supply line 3+ to the appropriate magnet 1 ... 9 when an impulse arrives from the brush 10 upon sensing a hole in the card. The energized magnet, Fig. 1a, closes one or more contacts to connect those of the lines 8, 4, 2, 1 to the supply 3+ which represent its value (thus, the " 7 " magnet connects up lines 4, 2 and 1). The system of contacts is represented by a dotted rectangle 1a in Fig. 2. The impulses supplied to lines 8, 4, 2, 1, Fig. 2, serve to establish holding circuits for corresponding magnets 14 and these set up similar holding circuits in a further set of magnets 16 before they are cleared to receive data from a succeeding card. Similar arrangements are provided for the other multiplier digits and the multiplicand digits. - The partial products of multiplier and multiplicand digits are represented by relays, e.g. for multiplier units x multiplicand pence, 8.8d, 4.8d, 2.8d ... &c., Fig. 1b, which control contacts in an addition chain. Certain partial products which are equal but cannot be energized together have their relays arranged on a common core, e.g. 4.8d, 8.4d. Transfers from the addition chain are provided for at convenient points by energizing relays, e.g. 4S3, 2S3 ... which control contacts in the addition chain of the next higher denomination. Moreover, according to the characteristic feature of the invention, only one addition chain in each denomination is connected to the final indicating devices, e.g. lamps 7, all secondary addition chains being connected to transfer relays in the "primary " indicating chains. The factors may be set up by means of a keyboard instead of a record card and the result indicating lamps 7 may be replaced by printing magnets, an accumulator, or punches for reproducing the result in a card.

The strip 4 is detachably attached to the front 7 of the envelope by side lugs 5 engaging with vertical slits 6, and the free end of the strip is folded over and gummed to the back of the envelop, thus preventing other postal packets from entering the open end of the envelope. To inspect the contents, the finger or thumb nail is inserted beneath the edge 11 to withdraw the lugs 5 from the side slits 6. The strip may be weakened or creased at the fold 9. The usual closing flap 8 can be dispensed with.
