The copolymer latex may be stabilized with a phenyl - alpha - naphthylamine/diphenylamine mixture.  The adhesive may also contain water, toluene, toluene/ethyl alcohol, chlorinated hydrocarbons, sodium butyl thiocarbonate, sulphur, carbon black, and zinc oxide.  Rubber and synthetic rubbers are bonded to metal or fibrous material by applying the composition and heating. Vulcanization, which may be simultaneous with the bonding is achieved with zinc oxide, channel black, phenyl alpha-and beta-naphthylamine, sulphur, stearic acid, pine tar, light process oil, mercaptobenzothiazole and N-cyclohexyl benzthiazyl sulphenamide.

Title: Improvements in or relating to transmitters for step-by-step telegraph systems
IPC: H04L19/00
Filed: 1937-09-17
Abstract: 502,521. Type printing telegraphy. CREED & CO., Ltd., THOMPSON, A. E., and SALMON, R. D. Sept. 17, 1937, No. 16773/38. Divided out of 490,404. [Class 40 (iii)] A transmitter for step-by-step type-printing telegraphy comprises means, actuated by the depression of a key, for releasing a shaft for rotation to a position dependent on the particular key depressed, means for locking the keyboard during transmission of impulses, and means for providing a predetermined delay between the actuation of the locking means and the release of the said shaft. By means described in detail in Specification 490,404, the depression of a key causes the keyboard to be locked and the release for one revolution of a cam 54, Fig. 3. Towards the end of this revolution the cam 54 depresses one end 55 of a pivoted lever to the other arm 56 of which is attached a detent 57 which thus rises and is held by a detent 61. The detent 57 disengages its cam 17 and so allows the rotation of the transmitting contact cams which are mounted on the same shaft as the detent cam 17, A number of impulses is transmitted until a shaft carrying a gear-wheel 29, driven from a gear 20 on the transmitting shaft, has rotated to a position characteristic of the key depressed. The keyboard is then unlocked by means described with reference to the parent case and the latch 61 is released so as to bring the detent 57 into engagement with its cam 17. The partial revolution through which the cam 54 rotates before releasing the transmitting shaft by means of the detent 57 provides the predetermined delay and ensures a definite pause between successive series of impulses.

Filed: 1921-06-20
Abstract: 178,398. National Pneumatic Co., (Assignees of Hedley, F., and Doyle, J. S.). April 11, 1921, [Convention date]. Operating doors electrically and pneumatically.-A sliding door of a vehicle is provided with a yielding buffer on its front edge which contains a pair of normally-separated contact members forming part of the circuit of the door-closing control magnet of the motor whereby, when an obstruction is encountered, the contacts are forced into engagement and the action of the motor is reversed to open the door. The door 1 is operated by a pneumatic motor 2 through a rocking-arm 3, and it is controlled by opening and closing electromagnetically-operated valves 5, 6. The front edge of the door carries a buffer member 7 enclosing a rubber or other flexible tube 11 containing a coiled spring 12 and an axially-positioned rod 14. These members 12, 14 are permanently connected through wires 13, 15 with conducting rods 10, 9 carried by the door and engaging members 20, 21 respectively leading to the magnet control valves 5, 6. When the door in closing meets an obstruction, such as a passenger, the contacts 12, 14 are forced into engagement and the circuit of the magnet valve 5 is completed, to reverse the action of the motor. Instead of, or in addition to the members 12, 14 the member 11 may carry a contact 50 adapted to bridge the contacts 51, 52 connected with the members 9, 10, when the obstruction is encountered. As shown in Fig. 1, the contacts 9, 10 and 21, 20 are out of engagement when the door is fully closed.

Abstract: 384,922. Dressing fish. BAADER, R., 33, Wakenitzmauer, Lubeck, Germany. June 17, 1932, No. 17189. Addition to 320,576 and 334,813, [both in Class 28 (ii), Kitchen and like appliances &c.]. [Class 28 (ii).] The fish is acted upon by angularlydisposed rotary discs b, bl having peripheries formed with radially projecting points d<1>. The discs b, bl operate one on each side of the backbone, and the points d<1> engage the rib-bones and prise them away from the flesh. A stationary knife d, which ploughs out the backbone, is arranged with its point d2 between the operative zones of the discs b, b<1>, and adjacent thereto is positioned a guide f which is shaped to spread the fish. The guide is of V-shape, having flange-like extensions at its widest section, and is slotted at f<2> to assist in the removal of the rib-bones by the discs. A modified form of guide is described for use when preparing fish for pickling, when a smooth flesh surface is of greater importance than the clean removal of the bones. This guide is not gapped at f<2> and the front edges are sharpened. An auxiliary knife is adjustably carried by the modified guide to cut the back of the fish partially or completely through, to prevent the natural resilience of the fish from closing the fish after the removal of the bones.

[Classes 40 (iii) and 40 (v).] To translate unmodulated carrier-wave signals into low-frequency signals, a voltage drop due to rectified high-frequency currents is applied to excite a glow lamp S in series with a valve V into lowfrequency oscillations or discharges. A telephone T or its equivalent is in series with the glow lamp to render the low-frequency oscillations audible. A potential for the glow lamp just below the extinguishing valve is obtained from a potentiometer P across the high-tension battery B, a condenser K is shunted across the glow lamp, and a resistance W is connected in series with the high-tension battery in the anode circuit of the valve. The light from the glow lamp may be used for recording, for example in copying-telegraphy.
