IPC: G07C9/00
Filed: 1920-02-20
Abstract: 164,085. Knispel, H., and Gerbsch, F. Feb. 20, 1920. Electrically-operated fastenings; locks, permutation.-Relates to electric locks for doors &c., and consists in providing a number of contacts at different places on the door &c., which are so connected and arranged that the lock is opened only when a circuit is closed by the external connection of a predetermined pair of the contacts, an alarm being given if connection is made between some of the other contacts. Switches may be arranged in the circuits of the different contacts in order to change at will the pair which enables the lock to be operated. In the arrangement shown in Fig. 1, a lock b is provided with an electromagnet which, when energized, opens the lock. The magnet is connected to a plate c covering the ordinary door-lock and to a battery l, which is also connected to a name-plate d. When the contacts c, d are connected, e.g. by means of a chain i, the circuit is completed and the lock b is thus opened. Two groups of contacts f<1>, f<2> are also provided on the door, and are connected in the circuit of a battery m as shown, so that if a person who is unaware of the connection necessary for operating the lock, joins any contact f<1> to any contact f<2>, this contact is closed, and an alarm, shown as a bell n and an optical signal p, is thus brought into operation. A relay o is arranged in conjunction with the alarm so as to enable it to remain in action independently of the battery m after it has been started as described by a current from the battery. A modification is described and shown in which a set of switches is provided on a common switchboard and enclosed by a cover, the switches comprising movable contact-arms which are connected by leads to contacts on the door, (such as d, f<1>, and f<2>, Fig. 1), and which can be set as desired so that any one of these door-contacts can be selected as one of the lock-operating contacts. When the selected contact is connected by a chain to the lock-plate (c, Fig. 1). which is permanently in the lock circuit, the lock is opened, but if an unauthorized person connects the lock-plate to any other of the door-contacts, an electric alarm is brought into action.

[Class 2 (iii)] Higher boiling hydrocarbons such as gasoline are produced from lower boiling hydrocarbons such as isoparaffins alkylated with olefines or polymerized olefines in the presence of an inorganic acid, an emulsion of hydrocarbon and acid is withdrawn, the reaction product is recovered and at least a part of the acid is returned to the reaction zone, the acid in the system being maintained in intimate contact with lower boiling hydrocarbons during at least 75 per cent. of the time it is in use in the process. The time may be reduced by carrying out the separation of product by extraction with the isoparaffin being alkylated. An emulsion breaking agent may be added to the reaction mixture, or demulsification can be hastened by cataphoresis or by supersonic vibrations. The separation is preferably carried out in two stages, so that the acid from the first stage, still containing hydrocarbon, is returned quickly to the reaction zone. The acid is preferably mixed with the isoparaffin before contact with the olefine. Examples are given of the alkylation of isobutane with butylene which may be replaced by propylene, isobutylene, cyclopentene, cyclohexene, amylenes or higher olefines. Polymers of the olefines or esters, ethers or alcohols, may also be used. The acid may be sulphuric, halosulphonic, phosphoric, or hydrofluoric or mixtures of sulphuric or phosphoric acids with boron fluoride and/or a hydrogen halide.

Title: Preparation of derivatives of sparingly soluble compounds
IPC: C01F11/00
Filed: 1941-04-28
Abstract: 547,019. Obtaining chemical derivatives from sparingly soluble, compounds. OCEAN SALTS (PRODUCTS). Ltd.. and ADAMS, B. A. April 28, 1941, No. 5493. [Classes 1 (i), 1 (ii) and 1 (iii)] Derivatives of sparingly soluble compounds are obtained by a process comprising forming a composite bed of the compound and an iron exchange material and passing a suitable liquid through the bed whereby concentration of the required ions is effected by alternate and repeated dissolution of the compound and ion exchange. The compound and ion exchange material may be stratified or intimately mixed together. A suitable method of producing the mixture is by passing a suspension of the compound upwardly through a column of the exchange material so that the compound is deposited in the interstitial spaces of the exchange. material. An effluent from the composite bed may be passed through an anion absorbing material and the effluent (water) from this step through the composite bed. In an example ground barytes was deposited in organic cation exchange material and after washing with water, hot water was passed through the material whereby an effluent containing sulphuric acid was obtained and passed through a bed of anion absorbing material (e.g. a metaphenylene diamine resin) from which sulphuric ions were subsequently removed by treatment with sodium carbonate to yield a solution of sodium sulphate. The barium ions were removed from the cation absorbing means by treatment with hydrochloric acid to give a solution of barium chloride.

Title: Improvements in and relating to electric signalling
IPC: H04L5/06
Filed: 1921-02-17
Abstract: 177,356. Davies, B., and Eastern Telegraph Co., Ltd. Feb. 17, 1921. Type-printing telegraphs.-In a system of signalling in which the selection depends on the use of different frequencies, the number of frequencies used is reduced by using in addition to the alternating currents, continuous currents of different strengths, each signal being represented by an alternating or continuous current alone, or a combination of both. A thermionic valve may be used at the receiver for relaying both currents or only the alternating current. The alternating current may be produced by a generator, but in the example shown, Fig. 1, an interrupter A, B is employed comprising discs N1, N2, N3, N4, 5, 5<1>. An ordinary transmitter operated by a perforated slip selects one of the brushes b1, b2, b3. The selected key connects one of three voltages V1, V2, V3, positive or negative, to line L through one of the interrupter discs N, &c. or continuous discs 5, 5<1>. The relay M short-circuits the line when no signals are taking place, a small inductance L delaying the rise in current through the tongue at the instant of closing. The signal currents, which are regarded as having alternating and direct components, flow through a number of tuned circuits L1, S1 &c. corresponding to the interrupter N1, N2 &c. and a " magnifier " M. Currents induced in one of the tuned circuits L1, S1 &c. pass to a thermionic amplifier A1 &c. and thus cause the operation of one of the magnets m1, m2 &c. The " magnifier " M supplies currents from a local battery B1 to the coil C in a strong magnetic field NS., these currents being proportional to the signal currents received. The arm J is thus moved to one of the contacts - V1 - V2 - V3, + V1 + V2 + V3 to close a circuit to energize one of the magnets M1, M2, M3, &c. Inductances l1, l2 are inserted to prevent the energizing of magnets M1, M2 when the arm J is moving to the contact V3. Alternatively, the same end may be achieved by the corresponding apparatus described in Specification 178,575. The movements of the two selected armatures conjointly act on the selecting bars of a perforator or printer, or may be used for relaying the signals.
