Patent GB-178084-A (GB)
Abstract: 178,084. National Cash Register Co., (Assignees of Pein, E. J. von). April 4, 1921, [Convention date]. Cash registers; printing totals; interlocking.- In machines of the key-set and operated type provided with independently operated means for printing a total, as described in Specification 142,436, a motor is employed for operating the shaft 89 from which the printing mechanism is driven and is released for operation, by depression of a key 148. An interlock prevents simultaneous manipulation of this key and the ordinary item keys. The starting key 148 pivoted at 149 is connected to a depending slotted spring- controlled link 151 adapted when sufficiently depressed to hook beneath a fixed flatted pin 157. A slide-bar 162 carries two spring-controlled latch members 159, 160 co-operating with each other and with the link and pin. The descent of the link causes an ear 165 thereon to depress the member 159 and thus through a flange 163 the member 160 also. The members are consequently freed from contact with the pin 157 so that the bar 162 can slide to the right under the action of the spring 166. This moves the arm 146 out of locking engagement with the motor clutch and switch for example, and as described in Specification 17534/08, permits the motor to start. The motor shaft 141 thereupon rotates the shaft 89 through one rotation and near the close of this movement a finger 177 returns the arms 146, the slide-bar 162 and the latch 160 to normal position. This return is unaffected by continued depression of the starting key which must therefore be released before a second cycle can commence. The interlock between the motor-starting and item keys comprises a pitman 203 pivotally connected to the key 148 and bearing a projection 202 to co-operate with a slotted disc 200 on the coupler-driven shaft 78. As an alternative to the motor, a hand crank may be used for rotating the total-printing shaft and be arranged to drive through a flexible connection and clutch device so that the motor may operate without turning the crank. In the Specification as open to inspection under Sect. 91 (3) (a), Specifications 20280/98, 27802/03 and 150,735 also are referred to.

Title: Plant for the production of carbon dioxide
IPC: C01B32/50
Filed: 1934-06-19
Abstract: <PICT:0439976/III/1> <PICT:0439976/III/2> Carbon dioxide is generated by combustion, absorbed in a solution of alkali carbonate and recovered by distillation from the absorption liquor, the plant employed being such that the furnace in which the carbon dioxide is generated, the boiling device in which the carbon dioxide is driven from the absorption liquor and heat exchanging means are combined in a single structional unit and the arrangement being such that heat exchange is provided between the hot gases of combustion, the inflowing absorption liquor and the out-flowing spent absorption liquor.  As shown, coke is burnt on a grate 31, Fig. 4, of a combustion chamber 29, the gases passing down through pipes 34 into a receiver 35 and from thence out of the apparatus to an absorption tower through a pipe 2.  The main combustion air is introduced at 32, and a secondary air supply at 33.  Lye from the absorption tower charged with carbon dioxide enters the apparatus through a pipe 14 and passes through a coil 37, chamber 36 and pipes 38 to a sprinkler which sprays the lye into an evaporating pan 40.  The expelled carbon dioxide passes out through a pipe 16 while the spent lye overflows into a chamber 41 and passes away through a pipe 11, this pipe is so constructed that the coil 37 is kept immersed in the out-flowing lye. Heat exchange between the out-flowing combustion gases in pipes 34, the inflowing lye in the coil 37 and chamber 36, and the out-flowing spent lye in chamber 41 is thus effected.  The gases leaving by the pipe 2 are driven by a blower through an ash trap and a coke filled cooling and purifying scrubber into an absorption tower for treatment with alkali carbonate lye supplied through the pipe 11 and a reservoir.  The carbon dioxide flows through the pipe 16 for storage after the removal of water vapour by condensation.  Gases, treating with liquids.--The combustion gases containing carbon dioxide passing through the pipe 2 enter an outer coke filled scrubber 4 irrigated with water from a sprinkler 8.  The cooled and purified gases are pumped by a pump 6 through a jet distributing device 7 into an inner concentric absorption tower 5 fed with potash lye by means of an atomizing device 12 whereby the carbon dioxide is absorbed.  This combined scrubber and absorption tower may be replaced by an absorption tower which is provided with means which cools both the entering lye and the absorption space.  The absorption tower is also jacketed for the upper part of its length.  In this jacket, carbon dioxide which has escaped absorption in the main absorption tower bubbles through further alkali lye which eventually overflows into pipes which lead to the bottom of the absorption tower.  In this modification the gas inlet to the jet distributing device is directed downwards.

Title: Direction indicator for automobile vehicles
Inventor: CHEZEAU PAUL
IPC: B60Q1/36
Filed: 1954-06-23
Abstract: 769,420. Road-traffic signals on vehicles. ETABLISSEMENTS DUCELLIER. June 23, 1954, No. 18422/54. Class 118 (2). An oscillating direction indicator of the electromagnetically - operated semaphore arm-type comprises a casing 1 in which is pivoted an arm 3. The arm 3 carries lamps 5 and has an extension piece 6 shaped in a circular arc concentric with its pivot 4 and comprising a non-magnetic part 6a and a soft iron part 6b. A co-operating curved solenoid 2 is so arranged that upon energization it attracts the soft iron core 6b and thereby raises the arm 3 to the horizontal position. Contacts 10, 11 are connected in the circuit of the solenoid 2 and are allowed to open by the cam 9 when the arm 3 is in its horizontal position; the arm 3 then falls under gravity or a return spring whereupon contacts 10 and 11 are closed; the arm 3 thus takes on an oscillating motion. A resiliently mounted permanent magnet 7 acts as a stop and means for locking the arm when in the unoperated position; the relative polarities of the magnet 7 and solenoid 2 are such that the latter when energized causes repulsion between permanent magnet 7 and the core 6b. The portion of the arm 3 containing the lamps 5 is circular and translucent and when the indicator is at rest a circular segment projects from the casing 1 to act as a vehicle light. The indicator is fitted in a vehicle body by insertion into an aperture of the same size as the casing 1; firstly a lug 13 is introduced obliquely, and then pressure is exerted on the lower portion to bring the casing vertical and cause a stud 14, mounted on a blade spring 15, to lock the device in position. Alternatively the indicator may be fitted outside the body so as to protrude from the contour of heavy vehicles.
