Title: Improvements in and relating to putties and mastics
Inventor: SCOTT EDGAR EDWARD
IPC: C09D5/34
Filed: 1960-10-26
Abstract: The invention comprises a putty or mastic comprising a vegetable drying oil and calcium carbonate in finely divided form having particulate or finely divided mica dispersed therein.  It is preferable to replace 2 to 20% by weight, and more preferably 2,5 to 5%, especially 3,75%, of the calcium carbonate in said putty or mastic by the mica and to keep the milling time, after the addition of the mica, to a minimum.  A semi-drying vegetable oil may be incorporated into said putty or mastic.  In the examples linseed oil putty, metal casement putty and curtain wall mastic were each made from putty whiting and mica in the proportions of (1) 99 parts by weight to 1 part, (2) 97,5 parts to 2,5 parts, (3) 95 parts to 5 parts and (4) 90 parts to 10 parts whiting to mica.  The resistance to cracking increased as the percentage of mica increased but the handling properties of (3) and (4) were inferior to those of (1) and (2).

Title: Process for the removal of hemicellulose from hemicellulose- containing caustic liquors obtained in the treatment of cellulose-
IPC: D21H17/25
Filed: 1973-08-02
Abstract: 1409586 Recovering hemicellulose KESKUSLABOBATORIO - CENTRALLABORATORIO AB OY 2 Aug 1973 [23 July 1973] 36805/73 Heading C3A [Also in Division D2] In processes such as the treatment of cellulose with alkali, wherein hemicellulose and cellulose degradation products are dissolved in an alkaline treatment liquor, the alkali is freed from these solutes by precipitating them with one or more organic compounds of boiling point below 100 C. The organic compounds are then boiled out of the alkali and the purified alkali returned to the process. The hemicellulose precipitated may be recovered by filtration or centrifugation and may be used in various ways. When the process is the preparation of alkali cellulose for viscose production, the hemicellulose may be reincorporated in the process. Example 6 discloses the incorporation of the hemicellulose into paper board.

A heel attaching machine of the type described in Specification 607,345 is modified to accommodate lasts with passageways, through which the screws pass, at different angles. This is obtained by pivoting the guide 60, for the hollow spindle 78, by a pin 62, and having a spring loaded plunger 70 which fits into one of two notches in the guide 60 so that the spindle 78 is locked in one of the two positions shown in Fig. 1. To allow for varying sizes of passageways 28, 28a in the last 26, 26a a sleeve 81 may be fitted over the spindle 78 and held in position by a catch 85. In the position of Fig. 2 (not shown) the bed plate 110 must be free to tip backwards, but is prevented from tipping forward, during removal of the shoe, by lugs 117. In the position shown in Fig. 1 the bed plate 110 is prevented from tipping by moving the sliding plate 111 so that it engages the abutment 119. When attaching Louis style heels the hold-down 42 may be replaced by a single U-shaped hold-down (not shown).

Filed: 1928-12-13
Abstract: 302,725. Krupp Grusonwerk Akt.-Ges., F. Dec. 21, 1927, [Convention date]. Thermionic relays.-In a process for separatng materials, particularly raw mining products, the entrance of the material into the field of an induction coil or condenser or both in one of two oscillating circuits, tuned to the same frequency and each acting on an amplifying valve, causes a phase displacement between the anode currents in the oscillating circuits, the current or voltage generated being utilized, either directly or after amplification, to control a separating apparatus. The material is passed through the field of a coil 11 or condenser 12 or both in the circuit 2 which is tuned to the same frequency as the circuit 1 each being connected to a hotcathode valve 3 acting as a high-frequency generator and each anode circuit being provided with resistances 6, 7 respectively. The current produced in the conductor 10 is transmitted through an oscillating circuit 13 and valve 14 to a transformer, the secondary circuit of which contains a glow discharge tube 16, the current through the latter being utilized to control a separating apparatus. In place of the resistances 6, 7 the primary windings of two transformers, the secondary windings of which are in opposition, may be used. With the phase displacement between the two primary currents a resulting E.M.F. is created in the secondary circuit which is transmitted to an amplifier valve in the anode circuit of which is connected the primary winding of the transformer. Specification 284,307, [Class 72 Iron &c.], is referred to.

A deadcentre spring 17 is arranged between the dolly 14 and the contact-member 16. In the form shown the other arm of the member 16 is pivoted to the base, but in modifications it may be pivoted to another bracket 23 and the dolly 14 may also be supported entirely by the strap 12 instead of partly by the base. The limiting positions of the dolly 14 are determined by the sides of a triangular projection on the dolly engaging the side of the lug 20. The point of the projection forms the point about which the dolly pivots. The Figure shows only one half 1 of the switch body. A complementary portion is adapted to be screwed on top.

Abstract: 880,310. Radio direction finding; radio signalling. TELEFUNKEN G.m.b.H. Nov. 3, 1959 [Nov. 6, 1958], No. 37257/59. Classes 40(5) and 40(7). According to one aspect of the invention a system for the supervision of a plurality of vehicles from a control centre comprises a transmitter on each vehicle and a receiver at the control, all operating on a common frequency and each transmitter including a precision clock such that the transmitters are brought into operation at times in accordance with a predetermined programme which allots different transmitting times to each transmitter. The receiver also includes a precision clock so that the transmissions received can be identified by the times of reception. According to another aspect of the invention, a system for the supervision of a plurality of vehicles comprises a receiver on each vehicle, all operating on a common frequency, each receiver including a precision clock such that the receivers are brought into operation at times in accordance with a predetermined programme. A transmitter at a control centre transmits to each vehicle under the control of a precision clock. By the use of spaced receivers or transmitters a fix may be determined. Preferably the transmission consists of pulses and contains information of use to the receptor. In a first embodiment several vehicles F1, F2, F3, each carry a transmitter Sl, S2, S3, and a clock ZNI, ZN2, ZN3. The control comprises a receiver E and a clock ZN. All the clocks are synchronized. If the transmitters are brought into operation in the sequence Fl, F2, F3 at predetermined times, the range of each of the vehicles can be determined by noting the time taken for the initial pulse of each transmission to arrive at the receiver, the time at which transmission started being known by means of the clock at the receiver. It is arranged that the times between the transmission of successively transmitting craft are sufficiently spaced to forestall any possibility of overlap at the receiver. The use of three spaced receivers E5, E6, E7 and clocks ZN16, ZN6, ZN7, Fig. 4, enables a fix to be made by correlating the arrival times 15-17 of signals from a craft F4 in a computer R. The positions of the various craft may be shown on a cathode ray tube display and the tracks of such vehicles will be shown as spots f4, f5, indicating the vehicles positions during a number of transmission periods, if a long after-glow display is used. A device Sp2 may feed additional information to the display, e.g. vehicle identification numbers. The system according to the second aspect of the invention is described with reference to Fig. 6 (not shown), and Fig. 7 illustrates the means whereby a vehicle F15 may obtain a fix using the sequential transmissions from transmitters S12-S14. The transmit times 112- 114 are determined by means of the precision clocks and the fix calculated in a computer R1.
