Title: Improvements in, or relating to, electrical switches of the tumbler type
IPC: H01H23/20
Filed: 1933-12-02
Abstract: 428,877. Tumbler switches. CRABTREE, J. A., Endwood, Little Aston Park, Sutton Coldfield. Dec. 2, 1933, No. 33883. [Class 38 (v)] A snap-action tumbler switch is constructed so that the first part of the breaking movement takes place at low speed so that when used on alternating current a short arc only is drawn and is extinguished when the voltage cycle passes through zero. The tumbler a drives through a spring toggle lever b a contact arm c pivoted on the tumbler pivot pin c<1>. At the lower end of the arm c is a massive insulator d through which passes a contact bar e adapted for engagement with a contact clip f. The toggle link b is formed with flanking levers b<1> which are arranged on either side of the spring, (not shown), and which engage fixed abutments b<2>, b3 to give a positive start to the contact arm as described in Specification 425,424. The switch is shown in the dead centre position and the contact f is just about to leave the contact e. As the effect of the spring is small at this point, and owing to the inertia of the mass d, the first part of the breaking movement will be relatively slow, and the latter part will be rapid as the spring has greater effect.

Abstract: Monomeric methylol derivatives of quaternated ureas are prepared by condensing such a urea with formaldehyde, or a substance yielding formaldehyde, at a pH of 7-10 and a temperature of 10 DEG C.-20 DEG C.  The quaternated ureas are prepared by converting a polyamine containing at least 3 amino groups, at least 2 of which are primary or secondary amino groups, into a polyurea containing at least one free amino group, and quaternating the free amino group(s).  As polyamines there may be used diethylene triamine, triethylene tetramine, dipropylene triamine, tripropylene tetramine; polyamines obtained by reduction of the addition products of acrylonitrile with polyols, amines and other compounds containing active hydrogen atoms; aromatic polyamines; long chain amines obtained by the condensation of polyamines with polyhalides.  The conversion into ureas may be carried out by reacting the polyamine with alkali cyanates, nitro-urea, phosgene, ammonia or urea.  The quaternation may be carried out with dialkyl sulphate, alkylhalides, or derivatives (e.g. esters or amides) of halogen-carboxylic acids.  Several examples are included in the Specification.

Abstract: 957,651. Preserving and curing cheese. ARMOUR & CO. Sept. 14, 1962, No. 35190/62. Headings A2B and A2D. [Also in Division B8] In a method of packaging and curing consumer size cuts of cheese, cheese curd is moulded to make green cheese, the cheese while green is cut into consumer size pieces which are then individually wrapped in consumer type wrappers prior to aging, the consumer size pieces of cheese are cured in the consumer type wrappers and the gas accumulated during curing is withdrawn, as by the application of vacuum. Preferably a consumer type label wrapper having a mould inhibitor coating (sorbic acid or propionates) on a surface next to the cheese is used and the wrapper is folded about the cheese with substantial overlap providing mould inhibitor treatment on surfaces which air must pass between the folds of the wrapper to reach the cheese, Figs. 3 and 4, and the unsealed consumer size pieces of cheese wrapped in the consumer type wrappers are stacked in merchandising boxes or containers 20, Fig. 5, in storage for a sufficient period for the curing of the cheese as wrapped. If the pieces are sealed, a brief exposure to vacuum during or following the curing period will withdraw the surplus gas. The wrappers may be sealed or resealed after curing either by steam treatment, whereby the natural oiling of the chees causes the wrapper to adhere to it, or by conventional heat-sealing of the lapping plies of the wrapper. The curing and sealing may be carried out in a chamber 21, Fig. 7, provided with vacuum and steam lines 22 and 23, respectively. Wrapping films mentioned: "Saran" or "Cellophane" (Registered Trade Marks) to which metal foil has been laminated, with or without a coating of wax, or Cellophane film coated on both sides with Saran by extrusion or lamination. Such a composite film may be further laminated or coated with polyethylene before being coated with wax.

Title: Improvements in or relating to printing telegraph exchange systems

Filed: 1936-12-23
Abstract: 471,406. Telegraph exchange systems. SIEMENS & HALSKE AKT.-GES. Dec. 23, 1936, No. 35298. Convention date, Dec. 23, 1935. [Class 40 (iii)] A releasing signal is sent to both calling and called subscribers on occurrence of a breakdown of an established connection. Normally, a calling party is unaware of the breakdown and in the case of an automatic exchange, continuation of transmission may result in the setting up of a false connection. The arrangement shown in Fig. 2 comprises a connection between two four-wire lines FL1, FL2, the dotted lines representing connections over plugs and jacks or selector switches. In the setting up of a connection, contacts represented by keys, Tea, Teb, are operated and supervisory relays A, B operate and hold in series with the transmitting relays SR1, SR2 of the two directions, the contacts being restored when the connection is established. If either of the dotted connections is broken, the corresponding supervisory relay falls back so that the transmitting relays SRI, SR2, are connected to negative battery to transmit a negative release signal to both subscribers. Further, if the battery supply fails, relays A and B, on relapse connect relays SR1, SR2 to condensers C1, C2 which have been charged so that SR1, SR2 send the release signal in this case also. Rectifiers G1, G2 or high resistances prevent discharge of the condensers over other circuits connected in parallel. The relays A, B are constructed to hold in spite of current reversals and may control supervisory lamps La, Lb.
