Title: Improvements in or relating to tackers
IPC: B25C5/11
Filed: 1940-04-17
Abstract: 540,611. Stapling. LINSKY, B., and LINSKY, J., (trading as SPEED PRODUCTS CO.). April 17, 1940, Nos. 6964 and 6965. Convention dates, July 22, 1939 and Feb. 17, 1940. [Class 89 (iii)] In a stapling machine of the type in which a driver is adapted to force a U-shaped staple through a passage in the head of the machine and through a thickness of material placed at the end of the passage, the machine having a magazine for the staples and means for feeding the staples into the path of the driver, a cover is provided tor closing the magazine, the staple-ejecting driver being movably guided by the cover and having a shock-absorbing plunger movable relatively to the driver. The head is weighted in line with and above the driver to reduce recoil. Shockabsorbing spring means normally hold the plunger depressed, and power spring means normally hold the driver depressed. Means are provided for indicating the near exhaust of the staples. Staples 22 are carried by an inverted channel-shaped strip 16 and urged toward the driver by a follower 24 advanced by a spring 155. The driver 90 is carried by a block 89 bored to receive a spring 80 abutting at its upper end against plates 76 of a recoil-absorbing laminated metal core. The bore through the block is divided by a plate 100, and below the plate a shock-absorbing spring 107 stronger than the spring 100 abuts against a plunger 104 normally contacting an anvil 110. The upper part of the stapler serves as a cover for the magazine, to which it is pivoted at 45, a saddle or seat 54 having upstanding sides 52 normally widely spaced from the sides of the cover but laterally movable against locking means provided by dimples in a spring member 60 to permit either upstanding side to contact with the side of the cover. The spring 155 passes round a roller 152 carried by a latch 146, the pivot of the roller co-operating with recesses 162 in projections from a housing 13 for the magazine, to hold the cover in position. An operating handle 119 for the stapler is pivoted at 116 to the cover. When the handle is depressed against the thrust of a spring 134 a pawl 120 raises the driver until the pawl slips past the edge of a notch 130 to allow the spring 80 to depress the block 89 to drive the staple. To prevent the end staples being lifted when the cover is lifted about the pivot 45, a bridge piece 175 joins the sides of the magazine housing near the delivery end. To indicate the near exhaust of the staples, the follower 24 has a red spot which ultimately registers with an opening 171 in the magazine housing.

Title: Separation of liquid mixtures and concentration of solutions containing solids
IPC: C01D1/42
Filed: 1968-02-13
Abstract: 1,221,673. Separation of liquid from a solution by evaporation. VARTA A.G. 13 Feb., 1968 [13 Feb., 1967; 18 Feb., 1967; 11 March, 1967; 1 April, 1967 (2)], No. 6995/68. Heading B1B. [Also in Division H1] Liquid is separated from a solution of two or more liquids or from a solution containing dissolved solid by contacting the solution, preheated if necessary, in chamber 02 with one side of a porous solid layer 01, impermeable to the solution, whereby vapour is evolved from the solution into a diffusion space on the opposite side of the layer and is then condensed on a condenser surface spaced opposite the porous evaporator layer. When the apparatus as shown is used to separate a liquid mixture, a temperature gradient is established along the direction Z of layer 01. Vapour of the liquid of highest volatility diffuses across gap 05, which contains a gas (e.g. hydrogen), the vapour condenses in the pores of porous layer 03, and the condensate passes into cooling chamber 04. A portion of the condensate is returned by conduit 09 from chamber 04 to chamber 02. The feed mixture is supplied through inlet 06 at a position where the composition of the mixture in the apparatus is the same as the composition of the feed. A lower boiling distillate fraction is withdrawn from the apparatus through valve V03; and a higherboiling, residual fraction is withdrawn through valve V02. When the apparatus is used for the distillation of water, conduit 09 is not operative; and the water-to-be-distilled is introduced at inlet 08. In some systems heat has to be fed to the evaporator walls. A rectification apparatus is also described comprising a plurality of cells each comprising an evaporation and condensation chamber separated by a diffusion gap, the cells being connected by conduits through which the condensate from one cell can be passed to the evaporation chamber of the adjoining cell, and non-evaporated liquid can be returned to the condensation chamber of the first-mentioned cell (Fig. 4, not shown). The separation of methanol and ethanol from aqueous solutions thereof is mentioned. The porous solid layers may be made by hotpressing nickel powder to form plates, and then treating the plates with polyamide resin so that it forms a burled coating which covers only a small portion of the area of each plate. Apparatus is described for the re-concentration of electrolyte from a battery of fuel cells (see Division H1).

Abstract: 1287217 Supply systems for consuming apparatus TRW Inc 13 Feb 1970 [17 Feb 1969] 7069/69 Heading H2H [Also in Division H3] A circuit arrangement for energizing loads with a relatively heavy direct current is provided with means for timing the supply to the loads which means cut off the supply to the loads automatically at the end of a desired period of energization. Window heating elements 19 of a motor vehicle together with an indicator lamp 20 are energized over a contact 26 which closes when a relay 22 is energized by operation of a push-button switch 16 after closure of the ignition switch 17 which causes a coil 23 to be energized, which energization is then maintained by a circuit including resistor 30. Simultaneously with the energization of the loads 19, 20 a timing circuit comprising resistor 32 and capacitor 33 is energized and a voltage developed on the gate 35 of a programmable unijunction transistor 37. Capacitor 33 charges up and after a predetermined time the charge on the capacitor reaches a value at which the transistor 37 becomes forwardly biased whereupon the transistor fires and the capacitor 33 discharges through a second winding 24 of the relay 22. Winding 24 is arranged to buck winding 23 such that energization of winding 24 causes the contact 26 to open thus terminating the supply to the loads 19, 20. A thermistor 40 is connected in parallel with resistor 34 to provide over-compensation for the temperature characteristics of the capacitor 33. Thus the energization time of the loads 19, 20 is longer at lower temperatures than at higher temperatures.

Title: Manufacture of dinitroparaffins
IPC: C07C205/02
Filed: 1945-03-23
Abstract: 1 : 3-Dinitropropanes of the formula R1CH(NO2)-CR2R3-CHR4NO2, wherein R2 and R3 may be alkyl radicals, the same or different, or may together form part of a cycloaliphatic ring and R1 and R4 may be hydrogen or alkyl radicals, the same or different, are prepared by reacting a nitro-alcohol of the formula R2R3C(OH)-CHR4NO2 or its ester with a nitroparaffin of the formula R1CH2NO2, the radicals R1, R2, R3 and R4 having the significance given above, in the presence of a primary or secondary amine.  The reaction may be brought about by allowing the reaction mixture to stand at room temperature; the dinitroparaffins may be isolated, for example, by treating the reaction mixture with aqueous mineral acid to dissolve out the amine and then separating or extracting the dinitroparaffin from the resulting mixture and finally distilling it.  The dinitroparaffins so obtained may be reduced by conventional methods to yield nitroamines and diamines and are useful in the manufacture of dyestuffs and medicinal substances.  The nitro-alcohols of the above formula wherein R2 and R3 are alkyl radicals may be prepared by interacting a ketone and a nitroparaffin in the presence of a basic substance or by hydration of the corresponding nitroolefine.  Suitable nitro-alcohols are nitro-tertbutanol, 1-nitromethyl cyclohexanol, 1-nitro-2-methyl - 2 - butanol and 3 - nitro - 2 - methyl - 2 - butanol.  Suitable esters of nitro alcohols include those of mineral acids and organic acids, for example nitro-tert-butyl acetate and 1-nitro-2-methyl-2-butyl acetate prepared by reacting the corresponding alcohols with acetic anhydride.  Specified primary nitro-paraffins are nitro-methane, nitro-ethane and 1-nitropropane. Amines mentioned are n-amylamine, diethylamine and piperidine.  In examples: (1) nitro-tert-butanol, nitromethane and piperidine or n-amylamine are mixed together and allowed to stand at room temperature until there is no further separation of water, i.e. for about two weeks: 1 : 3-dinitro-2 : 2-dinitro propane is isolated by neutralizing the mixture with hydrochloric acid and extracting with ether; (3) nitro-tert-butanol, nitroethane and piperidine are mixed together and allowed to stand at room temperature for 3 months, 1 : 3-dinitro-2 : 2-dimethyl butane then being recovered as above; (4) nitro-tert-butyl acetate is used in place of the alcohol in (1) above; (5) 1-nitromethyl cyclohexanol, nitromethane and diethylamine are boiled under reflux for 12 hours and 1 : 1-di-(nitromethyl) cyclohexane recovered as in (1) above.  Specification 584,789 is referred to.
