Title: Improvements in or relating to record-card-controlled statistical machines
Filed: 1928-04-05
Abstract: 314,928. Keen, H. H., and British Tabulating Machine Co., Ltd. April 5, 1928. Statistical machines; total-taking -A "grouped-card" statistical machine in which successive cards are compared by upper and lower reading devices in series for the purpose of automatic control, has a shunt across one card-reading device (preferably the upper one) which has a higher resistance than the part of the series circuit which is shunted, there being an operative electromagnet in the shunt circuit which effects the automatic control. The upper brushes 10 and lower brushes 12 are in series in circuits 40 having resistances 42 of about 3,000 ohms each, the brushes 10 being shunted by resistances 50 of about 4,000 ohms each when the upper card at brushes 10 disagrees as to its control perforation with the lower card at the brushes 12. Normally when the cards agree the current flows through circuits 40 and the current in circuits 50 is insufficient to energize the single magnet 56 in series with the circuits 50. When the cards at the brushes disagree the current is entirely through the shunts 50 and the magnet 56 energizes the motor control relay 27 which effects total-taking and resetting of the counters in the usual manner. A rotary currentinterrupter 48 closes the reading circuits just after each hole-position reaches the brushes and opens the circuits before the edges of the holes separate the brushes from the contact bar, thereby preventing sparking at the brushes. A modification is described in which the invention is applied to a machine operating on major and minor groups as in Specification 254,761. Instead of two sets of brushes in series, only one set of brushes may be used as in Specification 215,842, in which the functions of the lower brushes are performed by a delay-action device set up by the reading of each card and effective one card-cycle later. Specifications 190,144 and 250,953 also are 'referred to.
Patent GB-431422-A (GB)
Title: Improvements in and relating to means electrically responsive to the establishment of a contact of short duration
IPC: H01H47/22
Filed: 1934-04-05
Abstract: 431,422. Electromagnetic switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. April 5, 1934, No. 10364. Convention date, April 5, 1933. [Class 38 (v)] In an arrangement for the indication of or response to a contact of short duration, means such as a relay has included in its energizing circuit a condenser and a seriesconnected saturable inductance, the supply to this circuit being so adjusted that when in response to the establishment of the transient controlling contact a small change of voltage is set up in this circuit, the circuit is caused to " silt " and a relatively large change of current in the controlled circuit occurs. In the circuit shown in Fig. 2, the relay winding R is normally in series circuit with a saturable inductance D and condenser C and also with an additional impedance Z across which is connected a contacting member K. Normally when the contacts of K are disengaged the voltage across the members C, D is of a value E3, Fig. 1, below the value E1 at which a sudden rise of current occurs. If, however, the contacts K are closed even momentarily, short-circuiting the impedance Z, the voltage rises slightly above E1 so that a rapid rise of current occurs immediately and the relay R is operated. On re-opening of the contacts the relay R is maintained operated as the fall of voltage to E3 is not sufficient to cause the sudden fall of current shown in the upper curve for falling voltages. This sudden diminution is, however, produced by the subsequent opening of a switch W normally short-circuiting a resistance Z which reduces the voltage across C, D to a value below E2 and thus causes the opening of the relay R. The initial condition of the circuit may then be restored by reclosure of the switch W. The Specification as open to inspection under Sect. 91 also describes a similar but modified arrangement (Fig. 3, cancelled, not shown), designed to operate a relay in response to the movement of a cage in a mine shaft, variations of voltage in the controlling circuit being produced by variation of the reluctance of inductive chokes due to the movement past them of a body of magnetic material carried by the cage. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in door latches
IPC: E05B65/34
Filed: 1956-04-06
Abstract: 786,622. Latches. GENERAL MOTORS CORPORATION. April 6, 1956 [April 22, 1955], No. 10527/56. Class 44 In a door latch, a manual actuator is connected to a bolt-releasing mechanism by a pair of levers adapted to transmit angular motion, one to the other through an abutment which is adjustable to vary the angle between the levers. As shown, a rod 65 which is operatively connected at one end to a push-button mechanism (not shown), is connected at its other end to a lever 104 which is pivoted coaxially with a lever 100 on a stud 102. The levers are biased towards one another by springs 46 and 106, and a follower 114 formed integrally with lever 104 engages a cam 108 pivotally mounted on the lever 100. An end 106a of the spring 106 holds the follower in constant engagement with a serrated surface 112 of the cam 108, the arrangement being such that the cam can be set manually to provide, between limits, any desired angular relationship between the levers 100, 104, thus to compensate for variations in the length of the actuating rod 65. The latch comprises a freely rotatable bolt 34 on the outside of the latch casing 30 attached to a cam 40 on the inside of the casing, which is engaged by a detent 42 urged into engagement with the cam by the spring 46. A lever 48 engages a slot 42b in the detent 42 and is movable out of engagement with the detent to free the bolt by an inside handle operatively connected with the lever 48 through a lever 60 and a rod 64. The door may be locked from the inside by a button (not shown) connected through a rod 66 and lever 68 to a lock lever 74, having tabs 78, 80 which engage a swingable link 82, an arm 92 of the link 82 then blocking the lever 48 by engagement with an arm 56 thereof. The lock lever 74 may also be moved to locking position from the outside by means of a key-operated cylinder lock operating through pivoted levers 84 and 88. The link 82 is pivoted about a stud 98 on the lever 100, the arrangement being such that pivotal movement of the lever 100 in a clockwise direction by means of the press button operating through the rod 65, frees the arm 56 of the lever 48 from the link 82 and thus the detent 42.

Abstract: 1,128,130. Alkaloids; tenuazonic acid. INSTITUT NATIONAL DE RECHERCHE CHIMIQUE APPLIQUEE. 8 March, 1967 [15 March, 1966], No. 10928/67. Headings C2C and C2G. [Also in Division C6] In order to increase their yield of extractable alkaloids, poppies prior to any alkaloid extraction treatment operations, are caused to ferment by means of micro-organisms applied thereto, particularly of the species Alternaria tenuissima, Alternaria chartorum or a variety designated Alternaria Pl, all isolated from capsules of poppies naturally contaminated by mould. The isolated moulds may be cultivated and maintained in a medium consisting chiefly of poppy powder, kept in suspended animation in a medium having a reduced proportion of nutrient substances, or lyophilized. Crushed, sterilized and humidified poppies, particularly those of the species Papaverum album or Papaverum nigrum, are submitted to aerobic fermentation conditions while immersed in water, at a temperature ranging from 5‹ to 40‹ C. for a period of from one day to one month. The resulting fermentation product is subjected to alkaline extractions with chloroform, benzene and isobutanol followed by an acid extraction with chloroform. Small amounts of tenuazonic acid and other non-alkaloid substances are recovered by the acid extraction. In an alternative extraction procedure, the fermentation product is macerated twice in water and then in hydrochloric acid. The filtrate is rendered alkaline by ammonia to pH 9 and extracted with 3: 1 chloroform and isobutanol. The dry residue obtained by evaporating the solvent, is redissolved in chloroform and the alkaloid bases are extracted from this chloroform solution using a solution containing 2À33% by weight of hydrochloric acid. The acid-aqueous phase is then washed with chloroform, whereby the alkaloid bases of the isoquinolinic constituents (noscapine and papaverine) can be extracted from the organic phase. The acid aqueous extract free of alkaloids removed by the chloroform, is rendered alkaline by ammonia to pH 9 and this basic aqueous solution is then washed with 3: 1 chloroform and isobutanol, whereby the alkaloid bases of the phenanthrenic compounds (morphine and codeine) can be extracted from the organic phase.

Title: Process for removing carbon impurities from refractory rare metals, particularly tantalum
IPC: C22B9/14
Filed: 1930-04-08
Abstract: A process for removing carbon impurities from refractory rare metals for example tungsten, molybdenum, niobium, and particularly tantalum consists of mixing the metal with a suitable proportion of an oxide of a volatilizable metal which volatilizes at a temperature below the meltingpoint of the rare metal and heating in vacuo to a temperature at which the carbon will be oxidized and the volatile metal volatilized, the temperature of the mixture being maintained below the melting point of the rare metal.  The powdered mixture of oxide, for example magnesium, lithium, or beryllium oxide, and the metal is pressed into bars and heated for example by passing through the charge an electric current inside a sintering furnace.  The carbon monoxide is pumped away and the volatile metal deposits on the cooler parts of the furnace.  The oxides employed should preferably have a high proportion of oxygen.
